NOTICE!

  • During a power outage, the stove will shut down safely. Do not open the main door or ash pan door. During a power failure, the exhaust fan will not run. Keeping the doors sealed will allow the exhaust vent to draft out naturally. When the power is restored, the stove will not restart. If the exhaust temperature is still 126° F (52° C) when power is restored, the exhaust and convection fans will continue to run until the stove cools.
  • Over Fire Protection: If the stove is being over fired or burning too hot, the high limit switches will automatically shut down the stove to avoid damage to other components. If the temperature on the hopper reaches 197° F (92° C), the auger will automatically stop and the stove will shut down. The exhaust fan will continue to run until the proof of fire switch cools. Allow the stove to cool before attempting to re-ignite.

WARNING!

  • If the electrical power fails at any time when the stove is hot, keep all stove doors closed. This will limit the amount of smoke in the space.
  • Never shut the stove down (while running) by unplugging it from the power source.
  • Never shut the stove down (while running) by switching off the main power switch on the rear of the stove.

Installation

Pre-Installation
Unpacking:
Remove cardboard lid, outer box sleeve, and packing foam. Inspect for any shipping damage. (Preferably before delivery team leaves) Unscrew the mounting L brackets that secure the rear of the stove to the pallet. (4mm Allen) Open hopper lid and remove control panel, power cord, remote control, and all literature and packing material from the hopper. Open the front door via the latch on the right side behind the magnetic side panel (see picture) and remove cardboard packing material from the firebox chamber. Remove any tape or adhesive on the outside of the glass.

  • Front Door Latch

Mounting the Control Panel:
Remove all four Phillips mounting screws along the top rear of the stove where you wish to mount the controller bracket. Line up the holes in the back to the mounting bracket and secure in place. (Note: Universal mounting brackets are used, so only the far left and two right screws align. This is normal, and will still secure the panel to the stove) Find the data cable line at the rear of the stove, and plug it snugly into the back of the control panel. The universal mounting bracket will also allow for the control panel to be mounted to the side farthest from the exhaust port for specific vertical venting scenarios. (The two left and the far right screws are used in this case).

Placement:
Where you place your stove can significantly affect its performance and safety. Sketch out a plan for installing the stove, including dimensions, before permanent placement. When determining the location for the stove, wall stud location is critical. You may need to adjust the location of the stove to avoid encountering a wall stud. Before placing the pellet stove, connect the vent to allow for minimum clearances to combustible walls. Pro Tip: It is recommended that your pellet vent pipe be installed and serviced by a professional installer.

  • Side Mounting

Surge Protector

Protect the electrical components of your stove by using a surge protector.
WARNING!
Asphyxiation Risk:
DO NOT INSTALL IN A SLEEPING ROOM. Stove consumes oxygen in the room.

Floor Protection

Floor Protection
Non-combustible material (such as a hearth pad) is required underneath your stove.
ComfortBilt HP22 PELLET STOVE BLACK 17

The stove must be installed on a noncombustible floor, with proper floor protection, or on a masonry hearth. When a clean out T-vent is installed on the inside of a home, the floor protector must extend 2 inches beyond the rear of the T-vent.
When stove is vented straight through the wall and the clean out T-vent is on the exterior of the home, the minimum clearance is 2 inches from the back of the stove to the wall.

  • It is necessary to install Ember Protection: a type 1 floor protector for this stove.

  • The floor protector must be non-combustible material, extending beneath the stove with a minimum of 6 inches (152mm) in front of the glass, and 6 inches (152mm) to both sides of the stove.

  • Non-combustible floor protection must extend 2 inches (51mm) beneath the flue pipe of installed horizontal venting or under the top vent adapter with vertical installation. CANADA REQUIRED, USA RECOMMENDED.
    Notice:
    Be careful to protect the bottom of the stove and floor surfaces when moving the stove. Bottom edges of the stove may be sharp and can scratch surfaces.
    ComfortBilt HP22 PELLET STOVE BLACK 17

  • This will satisfy safety standards for both USA and Canada

Notice:
Clearances may only be reduced by means approved by the regulatory authority having jurisdiction.

Clearances to Combustibles

Confirm required clearances to combustibles (Combustibles include wood, drywall, etc…)
ComfortBilt HP22 PELLET STOVE BLACK 18Horizontal installation

  • Back walls to Stove rear corners: 5″ (13cm)

  • Back wall to Stove back: 2″ (5cm)

  • Side wall to Stove: 7″ (18cm)
    ComfortBilt HP22 PELLET STOVE BLACK 19Vertical installation

  • Back walls to Stove rear corners: 5″ (13cm)

  • Back wall to pellet pipe: 2″ (5cm)

  • Side wall to pellet pipe: 2″ (5cm)

  • Side wall to Stove: 7″ (18cm)

Notice:
When interior vent is installed vertically, the clearance to the back wall is determined by the vent size used. Install vent at clearance specified by the vent manufacturer. Take into consideration any upward turning elbows or tees.
CAUTION!
Take appropriate precautions to locate utilities within the wall and avoid contact.
Vent Termination Clearances
The stove vent must terminate on the outside of the building. Horizontal terminations must extend a minimum of 12″ from the wall. Vertical terminations must protrude a minimum of 24″ from the roof surface. In addition, all clearances listed below must be met.

  • Must have an approved cap (to prevent water from entering) or a 45 degree downturn with rodent screen.
  • If the termination is located on a windy side of the house, we suggest using an approved house shield to prevent soot from building up on the side of the house.
  • A vent must not be located where it may become plugged by snow or other material.

ComfortBilt HP22 PELLET STOVE BLACK 20A: Minimum 48″ clearance below or beside any door or window that opens. (This clearance may be reduced to 18″ if using outside air). We recommend the door or window be kept closed during operation. Minimum 12″ clearance below or beside any window that does not open.
B: Minimum 12″ clearance above any door or window that opens.
C: Minimum 24″ clearance from any adjacent building.
D: Minimum 7′ clearance above any grade, when adjacent to public walkways.
E: Minimum 24″ clearance above any grass, plants, or other combustible materials.
F: Minimum 36″ clearance from any forced air intake of another appliance.
G: Minimum 24″ clearance below eaves or overhangs.
H: Minimum 12″ clearance horizontally from combustible wall.
X: Must be a minimum of 24″ above the roof.
NOTICE:
Do NOT terminate vent:
In any location that will allow flue gasses or soot to enter or stain the building.
In any location which could create a nuisance or hazard.
In any enclosed or semi enclosed area such as a carport, garage, attic, crawl space, under a sun deck or porch, or narrow walkway.
Closely fenced area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway, etc…
Do NOT terminate vent below air inlet.
It is recommended that at least 3 ft of vertical pipe be installed when the stove is vented directly through a wall – this will create a natural draft, which will help prevent the possibility of smoke or odor venting into the home during a power outage.
Venting
Adding bends in the exhaust path restricts air flow, reduces performance, and provides a collection point for ash deposits requiring more frequent cleaning.
CAUTION!

  • Do NOT connect to any air distribution duct or system.
  • Do NOT install a flue damper in the exhaust venting system of this stove.
  • Do NOT Connect this stove to a chimney flue serving another appliance.
  • The structural integrity of the manufactured home floor, wall, and ceiling/roof must be maintained.
    Required: Only use a 3″ or 4″ type “L” or “PL” pellet venting system (such as DuraVent or Selkirk).
    ComfortBilt HP22 PELLET STOVE BLACK 21
  1. Mark and cut wall for venting penetration on exterior wall (if needed).
  2. Install wall thimble (sold separately) per manufacturer specifications.
  3. Install venting.
  4. Use a sealant (such as silicone) to create an effective vapor barrier at the location where the chimney or other component penetrates the exterior of the structure.

CAUTION!
Ensure that your stove venting terminates above the stove or the follow may occur:

  • Improper drafting.

  • Smoke may seep into the house.

  • Excessive soot.
    Install at least one smoke detector on each floor of your home to ensure your safety. They should be located away from the stove, and close to the sleeping areas.
    You should have separate CO monitors for areas near the stove
    Install pellet venting through wall and connect vent/pipe to stove

  • The pellet venting pipe (also known as L vent) is constructed of two layers with air space between the layers. This air space acts as an insulator and reduces the outside surface temperature of pipe to allow a clearance to combustibles.

  • A cap must be used at the termination of type L vent chimneys.

  • For elevations above 5,000 feet above sea level, 4″ venting is recommended. (Unless total length of venting is less than 6′ and uses no more than 1 elbow) Some venting manufacturers offer pellet stove adapters for their venting for easier installation.

  • Seal all pipe joints per the pipe manufacturer’s instructions.

  • Secure exhaust venting system to the Stove per the pipe manufacturer’s instructions. (Usually by using high-temp silicone (500°+)

  • Install termination cap.

  • Confirm all required Stove clearances to combustibles.

  • The vent must have a support bracket every 5′ of pellet vent when on the exterior of the structure.

Required: Use a 3″ appliance adapter as your first connection to the exhaust port of the stove.
Secure the appliance adapter to the exhaust port of the stove using a high temperature sealant. (Such as RTV silicone)

Pro Tip: Installing a clean-out “T” (sold separately), when venting vertically, can save time during cleaning, and is recommended to aid in the periodic cleaning and maintenance. Be aware of leak potential when installing an interior Tee.

  • Do not install flue damper in the exhaust venting system of this unit.
  • Use an approved wall thimble when passing the vent through walls. Use a ceiling support/fire stop spacer when passing the vent through ceilings. (Make sure to maintain minimum clearances to combustibles).
  • If using more than one T-vent or exceeding 180° of elbows, the use of 4″ venting pipe is recommended.
  • The vent must have a support bracket every 5′ of pellet vent when on the exterior of the structure.
  • Horizontal sections of vent pipe should have a 1/4 inch rise per foot. We recommend using the shortest venting and fewest elbows possible when venting horizontal.
  • Due to the potential for fly ash accumulation in horizontal venting sections, the maximum permissible horizontal venting length is 4 ft.
  • Contact local building or fire officials about restrictions and installation inspection requirements in your area.
  • Contact your local authority (such as municipal building department, fire department, fire prevention bureau, etc.) to determine the need for a permit.

Pro Tip: Use the bottom adjustable leveling feet for vertical movement of the stove up to 3/4″.
Outside Air Intake (available separately)

  • Connection from the intake pipe (2″ diameter pipe in rear of stove) to the outside of the house is REQUIRED for mobile home installation. It is recommended in tightly sealed homes with exhaust fans such as kitchen or bathroom fans, or in basement installations. This will eliminate poor performance due to negative pressure.
  • Only noncombustible pipe 2″ (or greater) in diameter is approved for outside air connections (Straight or flexible). PVC pipe is NOT approved and should NEVER be connected to the stove.
  • If the air inlet is connected to the outside, it MUST be terminated with a vertical 90° bend down, or with a wind hood. Failure to do so could result in a burn-back if high winds blow directly into the air inlet during a power outage.
  • Blockages, excessive length (more than 8 ft.), or excessive bends in the air intake pipe could lead to starvation of combustible air to the stove.

Notice:
The operation of exhaust fans, such as bathroom and attic fans, could create a negative pressure in the room, causing the stove to be starved of combustible air. Be sure to provide adequate ventilation in the room the pellet stove is located. If not, the vacuum pressure switch may shut off the operation of the pellet stove.
Equivalent Vent Length:
Comfortbilt pellet stoves depend on a combustion fan to pull air through the unit for combustion. The venting system restricts the ability of the combustion fan to move the required amount of air through the unit. A system with too much resistance will result in incomplete combustion, more frequent required cleaning and poor unit performance. It is always best to choose a location for the appliance that will result in a venting system with the shortest equivalent vent length
(EVL).
The following chart shows the equivalent vent length for common pellet vent components.

Equivalent Vent Length:

  • 90° Elbows or Tee: (Each)  5 EVL Units

  • 45° elbow: (Each)  3 EVL Units

  • Horizontal Pipe or liner: (Per Ft)  1 EVL Units

  • Vertical Pipe or Liner: (Per Ft.)    ½ EVL Units
    Maximum allowable equivalent vent length:

  • 17 EVL for 3” pellet vent pipe or liner

  • 27 EVL for 4” pellet vent pipe or liner
    Simple Horizontal Installation

  • Wall Thimble

  • Exhaust cap

  • Air Intake

  • Appliance Adapter

  • Floor Protection

Notice:
Excessive embers/sparks can exit exhaust cap if less than 4 ft of venting is used with no vertical rise.
Mobile Home Installation
Installation in a mobile home should be in accordance with the manufactured home and safety standard (HUD), CFR 3280, Part 24. This stove must be vented to the outside. In addition to the standard installation instructions, the following requirements are mandatory for installation in a mobile home:

  • The stove must be permanently attached to the floor.
  • Stove must have an outside air source.

OPERATION

Fuel Guide
Fuel Material and Storage

  • Wood pellets are generally produced out of wood waste such as sawdust and shavings. The raw material is dried, mechanically fractioned to size and extruded into pellets under high pressure.
  • This pellet stove is designed and approved to burn wood pellets, that comply with pellet fuels industry standards. Minimum of 40 lbs. density per cubic foot, 1/4″ to 5/16″ in diameter, with a maximum length of 1″, and less than 1% ash.
  • The performance of your pellet stove is greatly affected by the type and quality of the wood pellets you use. As the heat output of various quality wood pellets differ, so too will the performance and heat output of the pellet stove.
  • We recommend trying various brands and types before purchasing single-ton or muli-ton lots to ensure satisfaction. A 5-bag sample of pellets will give a good indication of what to expect from a certain brand/type.
  • Wood pellets need to be protected from direct exposure to moisture. Water, from sources such as condensation and humidity, causes pellets to expand and break down into unusable fuel.
  • Store fuel in dry location, not within clearances to combustibles of your stove.
  • It is important to select and use only pellets that are dry and free from dirt and debris. Dirty fuel will adversely affect the operation and performance of the unit, and can void the warranty. The Pellet Fuel Institute (PFI) has established standards for wood pellet manufacturers. Only use pellets that meet or exceed PFI standards for premium fuels.
  • Depending on the source material, pellets may have differing ash contents.

Higher Ash Content Material:

  • Hardwoods with a high mineral content.
  • Fuel that contains bark and other impurities.
  • Standard grade pellets.

Lower Ash Content Material

  • Most softwoods.
  • Fuels with low mineral or impurity content.
  • Most premium grade pellets.

Pro Tip: We recommend using Pellet Fuels Institute (PFI) certified pellet fuel with this stove.

  • The type of fuel you are burning will dictate how often you have to clean your fire pot.
  • If the fuel you are burning has a high dirt or ash content, it may be necessary to clean the burn pot more than once per day.
  • Poor quality fuel will cause clinkers to form in the burn pot. Clinkers are formed when non-combustible impurities are super heated and become glass-like.

Notice:
Tested and approved for wood pellet fuel only. Burning any other type of fuel voids warranty.(Cord wood, wood chips, corn, shells, cherry pits, etc…)

WARNING!
Do Not Burn:

  • Garbage, Lawn clippings or yard waste, Materials containing rubber, including tires, Materials containing plastic, Waste petroleum products, paints or paint thinners, or asphalt products, Materials containing asbestos, Construction or demolition debris, Railroad ties, or pressure-treated wood, Manure or animal remains, or Paper products, cardboard, plywood, or particleboard Burning these materials may result in the release of toxic fumes or render the heater ineffective and cause smoke.

Getting Ready
What to Expect
Combustion blower will turn on. (Panel will display “Igniting”)

  • Igniter will heat up.
  • Auger system will deliver pellets into the burn pot. (Smoke may occur during ignition but will evacuate once the flame appears in the burn pot.)
  • Convection blower will turn on once the stove heats up. (Panel will display “Heating”)
  • Combustion and convection blowers will continue to run even after your stove has been shut down. (Panel will display “Fire off” or “Cooling”)

Pro Tip

  • Odors and vapors are released during initial startup after purchase, and may persist for several days. Burning your stove on a higher level will speed the curing process. Open windows or doors for air circulation until curing/burn off is complete, or perform a “pre-burn” outdoors.
  • During startup and operation, the stove’s front door must be closed.
  • Priming is only required the first time the stove is lit, or after a “Low Temperature” fault due to low pellets in the hopper. (see Pre-ignition checklist)

Understanding Your Stove

  • Your stove utilizes a vertical auger fuel feed system that is operated by a microprocessor controlled digital circuit board. The digital circuit board allows the vertical auger fuel system to run in a timer based, non-continuous cycle. This cycling allows the auger to run for a predetermined amount of time. The auger pushes pellets up a chute located in the hopper. The pellets will then turn and fall through another chute into the burn pot.
  • Your stove is equipped with an automatic ignition system that should ignite the fuel within 5 minutes of displaying “Igniting”.
  • As pellets fill the burn pot and ignite, outside air is drawn through the fuel and heated during the combustion process which is then pulled across the heat exchange tubes by the exhaust motor.
  • As the stove reaches operating temperature, the room air is then circulated through the heat exchange tubes by a room air blower (convection blower), distributing warm air into the room.
  • The amount of heat that is produced by the stove is proportional to the rate of fuel that is burned.
  • Because a forced draft pressure is required for the combustion process inside the stove, it is extremely important that the exhaust system be properly installed and maintained.
  • Front glass and ash pan doors must remain closed while in operation and the seals on the doors must be properly maintained.

WARNING!
Fire Risk:
Keep combustible materials, gasoline, and other flammable vapors and liquids clear of the stove.

  • Do NOT operate stove with door open.
  • Do NOT operate stove without the ash pan drawer in place.
  • Do NOT operate stove without burn pot in place.
  • Do NOT store flammable materials in the stove’s vicinity.
  • Do NOT use gasoline, lantern fuel, kerosene, lighter fluid or similar liquids to start a fire in this stove.
    Keep all such liquids well away from the stove while it is in use, as combustible materials may ignite.

  11. Prime Auger – Now test and prime the auger system. Press the Combination Function . (A red indicator light will come  On Then the Enter button A feeding On Message will display on the screen, and the auger will engage to slowly draw pellets into the drop chute. After about a minute, pellets should start dropping into the burn pot. Once pellets start to feed, press the Exit button to stop the feeding. A “Feeding Off” message will display. Now press the Combination Function button again (the red indicator light will go out).

  12. Ready to start – The stove is now ready to start. (Empty any extra pellets from the burn pot before igniting)

Notice:
Every ignition sequence assumes an empty burn pot. Fuel left in the burn pot prior to ignition can cause the following: Delays in ignition, excessive smoking, puffing starts, and over-large fires.

Operational Modes
Before actually starting your stove, you will need to determine which operating mode you would prefer the
stove to run in. This stove can operate in one of three modes – Manual, Temp, and Weekly.

  • Manual: In this mode, you can adjust and set the heating power level to control the heat level. (1 – 5)
  • Temp: In this mode, you can set the room temperature and the stove will automatically adjust the heating power level to maintain the desired temperature. (Turning ECO option on in the settings will allow the stove to cycle on and off automatically based on the desired temperature)
  • Weekly: In this mode, the stove will work automatically during days and times you predesignate. You can have a program for each of the 7 days of the week, and up to 4 periods during the day.
  • Thstat: In this mode, it uses a simple wired thermostat to control the fire on and fire off cycles.
  • Pressing the mode select button will cycle through all of the different operating modes.
  • You must select your mode before turning on the stove. (Current mode will display in the upper left hand corner of the display screen)
  • Selecting a mode while the stove is burning may cause the stove to shut down and could force a 30-minute cool-down delay in restarting. You do not need to start operation of the stove to select your mode. To choose the mode, locate the mode select button on the controller.

Manual: In the manual mode, you have the ability to change the heat levels, which will increase or decrease the amount of heat that the stove puts out.

  • To change the power level in manual mode, use the “Scroll Up” or “Scroll Down” buttons on the control pad.
  • Pressing either of these buttons once will move the power level up or down one level.

NOTE:
Manual mode allows you to directly change the heat level of the stove. (1 – 5 bars) It does not allow you to adjust specific temperatures. (see Temp)
Temp: The Temperature Mode allows you to set the desired temperature of the room. The stove will increase or decrease the heat level automatically to keep the room close to the set desired set temperature.

  • To increase or decrease the “Call to” temperature, use the “Scroll Up” or “Scroll Down” button. The current room temperature will be displayed in the temperature display box on the screen, as will the “Call to” temperature.
  • If the room temperature falls below the “call to” temperature, the stove’s heat power level indicator will automatically rise to five. When the temperature has been reached, and maintained for about a minute, the heat power level will return to one and it will stay there until more heat is needed.
  • The desired or “Call to” temperature has a range of 61 – 82° F (16 – 28° C)
    ComfortBilt HP22 PELLET STOVE BLACK 39

NOTE:
In temperature mode, the stove will not shut off or go into standby. It will simply idle and continue to produce a fire until the room temperature falls below the “call to” temperature. When idling, the heat power level will read at level one in the power level box on the display screen. In order to allow the stove to cycle off and on automatically, the ECO option (see the “Settings” section) will need to be turned on.
Weekly: The Weekly Mode allows you to control and schedule the stove operation during set times and days throughout the week.

  • You can select four different operation times for each of the seven days of the week.
  • During the Weekly operation mode, the stove will run in a very similar way to “Temp” mode. Part of the weekly schedule program includes a desired “call to” temperature.
  • See the “Set Data” section for more information on programming the weekly schedule.

IMPORTANT:
Remember to set your weekly schedule in Weekly Mode before igniting a fire. If you attempt to set a weekly schedule while the stove is running in Manual or Temp modes, the weekly schedule will not set, and the screen will prompt you to wait until you have turned the stove off and it has cooled down before allowing you to retry.
Operational Modes (Continued)
Thstat: The Thstat Mode allows you to control the stove via a wired remote thermostat. (The stove will only work in this mode if connected to a thermostat)
A thermostat is a simple switch that is temperature activated.
When the thermostat engages, you will see an “ASKED” message on the screen. This is a call for heat, and the stove will automatically ignite, and run.
When the thermostat disengages, you will see a “NONE” message on the screen, and the stove will then go into a fire off mode, and allow the fire to die down and then go into standby for the next call for heat.

Note:
The correct information for this stove is the following:

  • Model: HP60S_U01
  • Voltage: ~115V
  • Frequency: 60Hz

What Does a Good Fire Look Like?
A good flame will be an active torch with a bright yellow center. Streaking of blue near the bottom of the burn pot is also a good sign of decent airflow pressure. Ash should reduce to a fine light gray powder. Gritty brown ash and fuel being ejected from the pot before fully reducing usually indicates too much air pressure under the burn pot, while dark/black ash or lazy, darker flames indicates an air shortage.
ComfortBilt HP22 PELLET STOVE BLACK 44

  • Level 1: The fire height may fluctuate up and down at this level as there is a lighter feed schedule, but on average the top should be just above the lip of the burn pot.
  • Level 3: The fire should be a fairly stable torch that comes up about half way up the chamber.
  • Level 5: The fire will be a tall torch, and the tops of the flame should reach to about the underside of the heat tubes.

Maintenance & Cleaning

A majority of all problems with pellet stoves are related to general maintenance and cleaning. Regularly cleaning your stove will allow it to function properly and extends the life of most of the stove’s components. Due to differences in fuel quality, stove cleaning intervals can vary wildly. However, the cleaner the stove is, the more efficiently it will burn.
WARNING!

  • Never perform cleaning or maintenance on a hot stove.

  • Allow unit to cool completely.

  • Interior components may still be hot, even when stove surfaces are cool to the touch. A protective glove is recommended.

  • Clinkers may remain hot for several minutes after they are pulled from the burn pot.

  • Never perform service with power supplied to the unit.

  • Maintenance & Cleaning Video

Side Panel Access
In order to access many of the areas needed to clean, you must first open the side panels that are magnetically held in place.
Each side panel simply pulls free from the front and is hinged from the back to fully expose the internals.
ComfortBilt HP22 PELLET STOVE BLACK 58

Heat Exchanger: Daily or as Needed
Clean the heat exchanger with the pre-installed scraper unit at the top of the stove when the stove is off and cool.
ComfortBilt HP22 PELLET STOVE BLACK 63

  • Pull the chrome knob in and out a few times. (Keep the front door shut to contain all of the ash as it falls)

  • The soot and ash will fall down to the burn pot and ash pan area.

  • Keeping the heat exchange tubes clean will keep your stove’s heat exchange process efficient.
    WARNING!

  • Never touch the scraper rod while the stove is hot or running. Severe burns can occur.
    Glass Air-Wash System
    Below the front door opening, there is a slide damper that can be opened and closed. This is part of the glass air-wash system.

  • Keeping the slider to the right will open up the damper and allow some room air to be drawn in and gently washed up the inside of the glass to help prevent excess soot buildup on the glass.

  • Optimal location is set to about 1/2 way open, but feel free to experiment for best results for your application.

Burn Pot: Daily or as Needed
ComfortBilt HP22 PELLET STOVE BLACK 63 Remove and clean the burn pot every time the hopper is filled with fuel, or as needed.

  • To empty the burn pot, lift it out of the cradle and dump it directly into the ash pan to either side.
  • Make sure all of the airflow holes in the burn pot are unobstructed.
  • Be sure any build-up is removed when clearing the airflow holes.
  • Using a small metal pick or drill bit can aid you if these get plugged through general use.

NOTE:
When reseating the burn pot, ensure that it sits flush on the cradle, and there are no gaps. Gaps around the base of the burn pot can cause airflow leakage and lead to pellet buildups.
Ash Pan Drawer: Weekly or as Needed
ComfortBilt HP22 PELLET STOVE BLACK 63

  • Ashes should be contained in a metal container with a tight fitting lid. The container of ashes should be placed on a noncombustible floor or, well away from any combustible materials.
  • If ashes are disposed of by burial, or otherwise dispersed, they should remain inside the enclosed container until all cinders have cooled.
  • The frequency in which the ash pan will need emptied will vary depending on the amount of fuel burned.

NOTE:
Ensure that the side latches are snug and have even pressure when drawer is replaced. A loose or uneven drawer can cause pressure leakage and lead to build-ups in the burn pot.
Interior Chamber: Weekly or as Needed
ComfortBilt HP22 PELLET STOVE BLACK 63
Clean the interior chamber with an ash vacuum once per week or as needed. (Ash vacuums have a metal canister that is specially designed to contain soot).

  • Remove the burn pot from the cradle and vacuum beneath.
  • Be sure to remove any ash buildup in and around the igniter tube.

NOTE:
When cleaning/vacuuming out the igniter tube, ensure that the igniter rod does not get nudged or pushed out of position.
Front Door Glass: Weekly or as Needed
Open the front door and clean the glass when cleaning interior chamber, or as needed.
ComfortBilt HP22 PELLET STOVE BLACK 66

  • Only clean the glass when the glass is cool.
  • Wipe the glass clean with a dry or damp rag.
  • If this does not remove all build-up, use a non-abrasive cleaner.
  • Using ceramic stove top cleaner can be helpful in removing soot build-up from the glass.
  • Inspect the gaskets around the door periodically and replace any worn, frayed or compacted gaskets. To replace main door rope gasket, pull the old gasket out of the track, and clean the track with a scraper and mineral spirits/denatured alcohol. Then stretch out the replacement gasket to ensure a proper fit. Run a healthy bead of high temperature caulking around the track, and lay the new gasket down inside, starting and ending on the hinge side of the door.

CAUTION!

  • Do Not operate stove with broken glass Do Not slam doors shut.
  • Do Not strike the glass.
  • Do Not use abrasive cleaners.
  • Do Not clean hot glass.
  • Replace with factory authorized high temperature ceramic glass only.|

(IMPORTANT) Rear Exhaust Chambers: Every ton (50 Bags) of Pellets Burned or as Needed
In addition to daily and weekly maintenance tasks, the exhaust chamber covers should be removed and the entire chamber vacuumed thoroughly once every ton (50 bags) of pellets burned or more often depending on pellet quality.

  • First, you will need to locate the cover plates to the rear exhaust chambers. These chamber covers are small, rectangular, metal plates that are affixed with 2 wing nuts or Allen screws.

  • There are two total chamber cover plates. One on each side of the stove behind the side panels.

  • One is about 6 inches below the air intake damper.

  • The other is on the top portion of the square exhaust pipe, adjacent to the exhaust motor housing.
    ComfortBilt HP22 PELLET STOVE BLACK 66
    ComfortBilt HP22 PELLET STOVE BLACK 66

  • Once you have located the chamber covers, you will then remove them by unscrewing the wing nuts/Allen screws and pulling the plate back.

  • There is a gasket behind the plate to help make an airtight seal so the stove does not draw in air through these panels. It is ok to cut through the center of the gasket to access the chamber behind it. As long as there is adequate gasket material around the perimeter, it will provide a proper seal.

  • Using a slender hose attachment for your ash vacuum, thoroughly vacuum out these chambers top to bottom. These chambers extend all the way up to the heat exchange tubes near the top of the stove, so it is imperative that the entire chamber is cleaned.

  • Using a sweeping motion with a slender, flexible brush will ensure that no area is neglected and as much of the ash and soot is removed as possible. (1″ – 1½” diameter coil brushes work great)

Exhaust Venting & Combustion Blower Housing:  Annually or as Needed

The exhaust venting (including Tee cleanouts and elbows), and combustion motor, housing, and impellers should be inspected and cleaned once per year or as needed.

  • There is a combustion motor gasket, which allows you to remove the motor from the housing, for inspection and cleaning. If damage occurs to the gasket, a new blower flange gasket may need to be added between the blower flange and the steel plate.

  • Do not over-tighten wingnuts during reassembly.

CAUTION!

  • Whenever performing maintenance on your stove, ensure that the stove is cool to the touch, and that
    power has been disconnected.

  • Fault codes and error messages can be cleared off of the main screen by pressing and holding the On/Off button for 5 seconds. (This acknowledges the error, and allows the stove to be restarted)

Problem: Total Loss of Power at the Control Panel
A total power loss at the panel indicates that the flow of electricity has been interrupted. The flow of electricity follows this path: Main power cord > rear switch block > wiring harness > main circuit board > data cable > control panel.

Solutions:

  • Ensure that the electrical outlet is working properly.
  • Ensure that the power switch is set to the On position (The — is On, the 0 is Off)
  • Ensure that all of the wires and connections are secure at the power switch, circuit board, and control panel.
  • Check the fuse at the back of the main power switch block. (There is an active and backup fuse located in a pull-out tray. The active fuse is in the saddle, while the backup fuse is in the plastic sleeve)
    ComfortBilt HP22 PELLET STOVE BLACK 81

Problem: Alarm – Low Temperature (Check Hopper/Burn Pot Message)
When the low temp alarm occurs, it means that the computer has lost communication to the proof of fire switch (POF). This usually happens because the fire got too small or went out to embers. A handful of reasons can account for this happening, but the most common is feeder interruptions. (Caused by low pellets in the hopper, or the hopper lid being left open too long during refueling, for example)ComfortBilt HP22 PELLET STOVE BLACK
81

Solutions:

  • Ensure that the hopper is not too low, or that the pellets are not bridging or creating a funnel at the auger mouth opening. (This can cause low density of pellets, and inconsistent feeding)
  • Check the Ash Cleaning Cycle (see Settings). This cycle may need to be shortened on the lower levels.
  • Ensure that the safety switches are staying engaged during operation. (for example: if the hopper lid is left open, the auger will not feed, resulting in this alert)
  • For chronic issues, switch the leads over to the backup POF switch at the exhaust housing.

Troubleshooting

Problem: Alarm – High Temperature/Overheat
The stove giving a High Temp or Overheat alarm could be caused by the room blower not moving enough hot air out of the stove, limited combustion airflow, an improper fuel-to-air ratio in the settings, or an install with excessive bends/elbows.
ComfortBilt HP22 PELLET STOVE BLACK 81

Solutions:

  • Ensure that the room blower fan is working properly, and that the blower voltages are not set too low. (If the blower fan is not spinning, try to manually flick it to check for resistance)
  • Ensure that the airflow pathways are unobstructed. (see Maintenance & Cleaning)
  • Ensure that the exhaust fan is not impeded, and is exhausting correctly.
  • When operating in Temp mode, ensure that the room temp sensor is not in a cold location, causing the stove to run on a higher level than needed.

Problem: Alarm – Failure to Ignite
The stove giving a failure to ignite message, means that either a fire failed to ignite, or that not enough heat was generated at the Proof of Fire sensor to engage the stove’s Heating mode.ComfortBilt HP22 PELLET STOVE BLACK
81

Solutions:

  • Ensure that the igniter is in a good position, and getting hot at the tip within three minutes. (see igniter troubleshooting video)
  • Ensure that the burn pot is seated and oriented correctly. (small hole and ring toward the back of the stove)
  • Ensure pellets are feeding and being delivered to the burn pot. (see feeder troubleshooting video)
  • Ensure that the front door and ash pan drawer are properly sealed.
  • Ensure combustion fan is engaging, and the there is sufficient airflow being drawn through the stove at the air intake pipe.
  • If the fire is established within 5 minutes and maintains a good flame throughout ignition, but the stove fails to switch to heating mode, try moving the wires over from the active Proof of Fire sensor to the pre-installed backup at the exhaust housing.ComfortBilt HP22 PELLET STOVE BLACK 81

Problem: Lazy or Dirty Flame / Buildup of Pellets in the Pot / Dark Black Smoke or Ash
If you see a buildup of pellets and/or black smoke in the main chamber or at the end of the exhaust, these are not normal emissions, and usually indicate a reduction of air flow.ComfortBilt HP22 PELLET STOVE BLACK
81

Solutions:

  • Check for clinkers or blockages in the burn pot, and that the burn pot is seated flush on the cradle. (Gaps between the cradle and burn pot can allow air to be drawn around the pellets instead of through them)
  • Check for leakages or loose seals/gaskets around the stove, such as around the glass door or ash pan. (Ensure the side latches of the ash pan are snug with about even pressure)
  • Check for potential blockages in the exhaust chambers or venting. (see Maintenance and Cleaning)
  • Ensure the intake air damper not closed off. (Loosen the 4mm set screw, and pull outward to open) *Damper is located at the base of the intake pipe on the inside of the stove, behind the side panel.

Problem: Auger not feeding pellets
The stove operates, but does not feed pellets.
Solutions:

  • Ensure that the hopper is full. When the hopper gets low, the pellets can funnel or bridge, causing a low density feeder problems.
  • Ensure that the hopper lid switch, and vacuum pressure switches are engaging.
  • Press the info button ( ! ) to check if Feed, Vacuum, and Limit are engaging.
  • Auger may have a buildup or jam. Empty the hopper and try to activate the auger in the diagnosis menu to see if the auger will turn.
  • Note: If the auger is making a squeaking or groaning noise, you may want to lubricate the auger system with a lubricant such as graphite powder or white lithium grease.

Problem: Alarm – Lost Connect
The stove giving a Lost Connect alert means that the panel is receiving power from the circuit board, but it is unable to communicate with it.
ComfortBilt HP22 PELLET STOVE BLACK logo

Solutions:

  • Ensure that the 4-pin data cable is connected snugly into both the back of the control panel as well as into the bottom circuit board.
  • Ensure that none of the 4-pin data cable wires have a loose connection at the white plastic connector.
  • Ensure that the data cable pinout is the same on both sides, and that the Transmit line (TX) and Receive line (RX) did not get swapped or pinned out incorrectly.
    Problem: ERR where room temperature should be
    The stove displaying ERR inside the house where the room temperature should be, indicates that the control panel is not receiving accurate temperature data from the room temperature thermocouple sensor.

Solutions:

  • Ensure that the room temperature sensor wire behind the stove is not crushed, cut,
    or damaged in any way.

  • Ensure that the room temperature sensor wire is securely connected to the white jumper connection on the circuit board. *see wiring diagram

  • Note: The stove will still operate correctly when set to the Manual operational mode.
    Problem: Temperature getting too warm in the room
    If the room temperature is getting too warm, it means that the stove is creating more heat than the space is losing over time. This is fairly common during mild temperatures or in the transitional seasons.
    ComfortBilt HP22 PELLET STOVE BLACK logo

Solutions:

  • Turn the stove off to allow the space to cool down.

  • Set the stove to a lower temperature (in Temp Mode) to allow the smallest fire
    possible.

  • Set the stove to a lower heat level (in Manual Mode) to allow the smallest fire possible.

  • If the stove is set to the lowest possible heat level or temperature and is still overheating the space, you can activate the ECO option to allow the stove to automatically cycle on and off based on room temperature data. *See Operation > Set ECO

  • Alternatively, you can install a simple, wired, remote thermostat. This can help maintain a more accurate temperature range for the space.

NOTE:
Activating the ECO function, or installing a remote thermostat will activate the electronic igniter much more frequently, causing more electricity to be used, and wearing the igniter out much faster.+
