PRODUCT FEATURES

OPERATION

This heater is clean burning. It requires no outside venting. There is no heat loss out a vent or up a chimney. Heat is generated by realistic, dancing yellow flames. This heater is designed for vent-free operation with flue damper closed. It has been tested and approved to the ANSI Z21.11.2 standard for unvented room heaters. State and local codes in some areas prohibit the use of unvented appliances.

SAFETY PILOT
This heater has a pilot with an Oxygen Depletion Sensing (ODS) safety shutoff system. The ODS/ pilot is a required feature for vent-free room heaters. The 0DS/pilot shuts off the heater if there is not enough fresh air.

AIR FOR COMBUSTION AND VENTILATION

WARNING : This heater shall not be installed in a room or space unless the required volume of indoor combustion air is provided by the method described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes. Read the following instructions to ensure proper fresh air for this and other fuel burning appliances in your home.

Today’s homes are built more energy efficient than ever. New materials, increased insulation and new construction methods help reduce heat loss in homes. Homeowners apply weather strip and caulk around windows and doors to keep the cold air out and the warm air in. During heating months, homeowners want their homes as airtight as possible.
Whiteites good to make your home energy efficient, your home needs to breathe. Fresh air must enter your home. All fuel-burning appliances need fresh air for proper combustion and ventilation.
Exhaust fans, some fireplaces, clothes dryers and some fuel-burning appliances draw air from the house to operate. You must provide adequate fresh air for these appliances. That will ensure proper venting of vented fuel-burning appliances.

PROVIDING ADEQUATE VENTILATION
The following are excerpts from National Fuel Gas Code. ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation.
All spaces in homes fall into one of the three following ventilation classifications:

1. Unusually Tight Construction
2. Unconfined Space
3. Confined Space

The information on Pages 6-8 will help you classify your space and provide adequate ventilation.
Unusually Tight Construction
The air that leaks around doors and windows may provide enough fresh air for combustion and ventilation. However, in buildings of unusually tight construction, you must provide additional fresh air.

Unusually tight construction is defined as construction where:
a. walls and ceilings exposed to the outside atmosphere have a continuous water vapor retarder with a rating of one perm (6×10 kg per pa-sec-m?) or less with openings gasketed or sealed and
b. weather stripping has been added on openable windows and doors and
c. caulking or sealants are applied to areas such as joints around window and door frames, between sole plates and floors, between wall-ceiling joints, between wall panels, at penetrations for plumbing, electrical and gas lines and at other openings.
If your home meets all three criteria above, you must provide additional fresh air. See Ventilation Air From Outdoors, Page 8.
If your home does not meet all three criteria above, proceed to Determining Fresh-Air Flow For Heater Location.

Confined Space and Unconfined Space
The National Fuel Gas Code, ANSI 7223.1/ NFPA54 allows two methods for determining whether the pace in which the heater is being installed is confined or unconfined space. The standard method defines a confined space as a space whose volume is less than 50 cubic feet per 1,000 Btu per hour (4.8 m? per kw) of the aggregate input rating of all appliances installed in that space and an unconfined space as a space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m? per kw) of the aggregate input rating of all appliances installed in that space. Rooms communicating directly with the space in which the appliances are installed*, through openings not furnished with doors, are considered a part of the unconfined space.
Where the air infiltration rate of a structure is known, the Known Air Infiltration Rate Method may be used. Follow The National Fuel Gas Code, ANSI 7223.1/NFPA 54 to use this method to determine if the space is confined or unconfined.

• Adjoining rooms are communicating only if there are doorless passageways or ventilation grills between them.
  DETERMINING FRESH-AIR FLOW FOR FIREPLACE LOCATION
  Determining if You Have a Confined or Unconfined Space Using the Standard Method Use this work sheet to determine if you have a confined or unconfined space.
  Space: Includes the room in which you will install fireplace plus any adjoining rooms with doorless passageways or ventilation grills between the rooms.

  1. Determine the volume of the space (length x width x height).
     Length x Width x Height = cu. ft. (volume of space)
     Example: Space size 20 ft. (length) x 16 ft. (width)
     x 8 ft. (ceiling height) = 2,560 cu. ft. (volume of space)
     If additional ventilation to adjoining room is supplied with grills or openings, add the volume of these rooms to the total volume of the space.

  2. Multiply the space volume by 20 to determine the maximum Btu/Hr the space can support.
     (volume of space) x 20 = (Maximum Btu/Hr the space can support)
     Example: 2,560 cu. ft. (volume of space) x 20 = 51,200 (maximum Btu/Hr the space can support)

  3. Add the Btu/Hr of all fuel-burning appliances in the space.
     Vent-free fireplace| Btu/Hr
     ---|---
     Gas water heater| Btu/Hr
     Gas furnace| Btu/Hr
     Vented gas heater| Btu/Hr
     Gas fireplace logs| Btu/Hr
     Other gas appliances| Btu/Hr
     Total| Btu/Hr

• Do not include direct-vent gas appliances. Direct vent draws combustion air from the outdoors and vents to the outdoors.
  Example:
  Gas water heater………..40,000 Btu/Hr
  Vent-free fireplace ………+.31.500 Btu/Hr
  Total =_71.500 Btu/Hr

  4. Compare the maximum Btu/Hr the space can support with the actual amount of Btu/Hr used.
     Example:
     Btu/Hr (maximum the space can support)
     Btu/Hr (actual amount of Btu/Hr used)
     51,200 Btu/Hr (maximum the space can support)
     71,500 Btu/Hr (actual amount of Btu/Hr used)

The space in the example is a confined space because the actual Btu/Hr used is more than the maximum Btu Hr the space can support. You must provide additional fresh air. Your options are as follows:/
A. Rework worksheet, adding the space of an adjoining room. If the extra space provides an unconfined space, remove door to adjoining room or add ventilation grills between rooms. See Ventilation Air From Inside Building, Page 8.
B. Vent room directly to the outdoors. See Ventilation Air From Outdoors, Page 8.
C. Install a lower Btu/Hr heater, if lower Btu/Hr size makes room unconfined.
If the actual Btu/Hr used is less than the maximum Btu/ Hr the space can support, the space is an unconfined space. You will need no additional fresh air ventilation.
WARNING : If the area in which the heater may be operated does not meet the required volume for indoor combustion air, combustion and ventilation air shall be provided by one of the methods described in the National Fuel Gas Code, ANSI Z223.1/NFPA 54, the International Fuel Gas Code, or applicable local codes.
VENTILATION AIR
Ventilation Air From Inside Building This fresh air would come from an adjoining unconfined space. When ventilating to an adjoining unconfined space, you must provide two permanent openings: one within 12″ of the ceiling and one within 12″ of the floor on the wall connecting the two spaces (see options 1and 2, Figure 2). You can also remove door into adjoining room (see option 3, Figure 2).
Follow the National Fuel Gas Code ANSI Z223.1/NFPA 54 Air for Combustion and Ventilation for required size of ventilation grills or ducts.
Ventilation Air From Outdoors
Provide extra fresh air by using ventilation grills or ducts. You must provide two permanent openings: one within 12″ of the ceiling and one within 12″ of the floor. Connect these items directly to the outdoors or spaces open to the outdoors. These spaces include attics and crawl spaces. Follow the National Fuel Gas Code ANSI Z223.1/NFPA 54, Air for Combustion and Ventilation for required size of ventilation grills or ducts. IMPORTANT : Do not provide openings for inlet or outlet air into attic if attic has a thermoset at controlled power vent. Heated air entering the attic will activate the power vent.

INSTALLATION

NOTICE : This appliance is intended for supplemental heating. Use this appliance along with your primary heating system. Do not install this appliance as your primary heat source. If you have a central heating system, you may run system’s circulating blower while using appliance. This will help circulate the heat throughout the house.

INSTALLING DAMPER CLAMP ACCESSORY FOR VENTED OPERATION
NOTE: When used as a vented heater, appliance must be installed only in a solid-fuel-burning fireplace with a working flue and constructed of noncombustible material.
For Massachusetts Residents Only: Installation of this vented gas log set in the Commonwealth of Massachusetts requires the damper be permanently removed or welded in the fully open position.
If your heater is a manually-controlled model, you may use this heater as a vented product. There are three reasons for operating your heater in the vented mode.

1. The fireplace does not meet the clearance to combustibles requirements for vent-free operation.
2. State or local codes do not permit vent-free operation.
3. You prefer vented operation.

If reasons number 1 or 2 apply to you, you must permanently open chimney flue damper. You must install the damper clamp accessory (to order, see Accessories, Page 38). This will ensure vented operation (see Figure 10). The damper clamp will keep damper open. Installation instructions are included with clamp accessory.
See chart for minimum permanent flue opening you must provide. Attach damper clamp so the minimum permanent flue opening will be maintained at all times.

• A equipment shutoff valve with 1/8″ NPT tap is an acceptable alternative to test gauge connection. Purchase the optional equipment shutoff valve from your dealer.
  For propane/LP units, the installer must supply an external regulator. The external regulator will reduce incoming gas pressure. You must reduce incoming gas pressure to between 11″ and 14″ of water. If you do not reduce incoming gas  pressure, heater regulator damage could occur. Install external regulator with the vent pointing down as shown in Figure 13. Pointing the vent down protects it from freezing rain or sleet.
  CAUTION: Use only new, black iron or steel pipe. Internally-tinned copper tubing may be used in certain areas. Check your local codes. Use pipe of 1/2″ diameter or greater to allow proper gas volume to heater. If pipe is too small, undue loss of volume will occur.
  Installation must include an equipment shutoff valve, union and plugged 1/8″ NPT tap. Locate NPT tap within reach for test gauge hook up. NPT tap must be upstream from heater (see Figure 14).
  IMPORTANT: Install equipment shutoff  valve in an accessible location. The equipment shutoff valve is for turning on or shutting off the gas to the appliance.
  Check your building codes for any special requirements for locating equipment shutoff valve to appliances.
  Apply pipe joint sealant lightly to male NPT threads.
  This will prevent excess sealant from going into pipe. Excess sealant in pipe could result in clogged heater valves.
  WARNING: Use pipe joint sealant that is resistant to liquid petroleum (LP) gas.

• Purchase the optional equipment shutoff valve from your dealer.
  Minimum inlet pressure for purpose of input adjustment.
  Figure 14 – Gas Connection
  We recommend that you install a sediment trap in supply line as shown in Figure 14. Locate sediment trap where it is within reach for cleaning. Install in piping system between fuel supply and heater. Locate sediment trap where trapped  matter is not likely to freeze. A sediment trap traps moisture and contaminants. This keeps them from going into heater controls. If sediment trap is not installed oris installed wrong, heater may not run properly.
  CAUTION: Avoid damage to gas control. Hold gas fitting with wrench when connecting it to gas piping and/ or fittings.
  CHECKING GAS CONNECTIONS AWARNING: Test aII gas piping and connections, internal and external to unit, for leaks after installing or servicing. Correct all leaks at once.
  WARNING: Never use an open flame to check for a leak. Apply a noncorrosive leak detection fluid to all joints. Bubbles forming show a leak. Correct all leaks at once.
  CAUTION: Make sure external regulator has been installed between propane/LP supply and heater. See guidelines under Connecting to Gas Supply, Page 13.
  PRESSURE TESTING GAS SUPPLY PIPING SYSTEM**

3. Keep control knob pressed in for 30 seconds after lighting pilot. After 30 seconds, release control knob. Now follow step 8 under Lighting Instructions, above.

INSPECTING BURNERS

Check pilot flame pattern and burner flame patterns often.
PILOT FLAME PATTERN
Figure 40 shows a correct pilot flame pattern.
Figure 41 shows an incorrect pilot flame pattern.
Incorrect pilot flame is not touching thermocouple.
This will cause the thermocouple to cool. When thermocouple cools, heater will shut down.
If pilot flame pattern is incorrect, as shown in Figure 41

• turn heater off (see To Turn Off Gas to Appliance).
•  see Troubleshooting, Page 28.

BURNER PRIMARY AIR HOLES
Air is drawn into burner through holes in fitting at entrance to burner. These holes may become blocked with dust or lint. Periodically inspect these holes for any blockage and clean as necessary. Blocked air holes will create soot.
MAIN BURNER
Periodically inspect all burner flame holes with heater running. All slotted burner flame holes should be open with yellow flame present. All round burner flame holes should be open with a small blue flame present. Some burner flame holes may become blocked by debris or rust, with no flame present. If so, turn off heater and let cool. Remove blockage, blocked burner flame holes will create soot.

CLEANING AND MAINTENANCE

WARNING: Turn off heater and let cool before cleaning.
CAUTION: You must keep control areas, burner and circulating air passageways of heater clean. Inspect these areas of heater before each use. Have heater inspected yearly by a qualified service person. Heater may need more frequent  cleaning due to excessive lintfromcarpeting, bedding material, pet hair, etc.
WARNING: Failure to keep the primary air opening(s) of the burner(s) clean may result in sooting and property damage.
Perform a periodic visual check of pilot and burner flame.
Once every year a qualified agency or certified chimney sweep should examine and clean the venting system of fireplace.
ODS/PILOT AND BURNER
Use a vacuum cleaner or small, soft bristled brush to clean.
BURNER ORIFICE HOLDER AND PILOT AIR INLET HOLE
The primary air inlet holes allow the proper amount of air to mix with the gas. This provides a clean burning flame. Keep these holes clear of dust, dirt and lint. Clean these air inlet holes prior to each heating season. Blocked air holes will  create soot. We recommend that you clean the unit every three months during operation and have heater inspected yearly by a qualified service person. We also recommend that you keep burner tube and pilot assembly clean and free of  dust and dirt. To clean these parts we recommend using compressed air no greater than 30 PSI. Your local computer store, hardware store or home center may carry compressed air in a can. If using compressed air in a can, please follow  directions on can. If you don’t follow directions on can, you could damage pilot assembly.

1. Shut off unit, including pilot. Allow unit to cool for at least thirty minutes.
2. Inspect burner, pilot and primary air inlet holes on orifice holder for dust and dirt (see Figure 42).
3. Blow air through ports/slots and holes in burner.
4. Check orifice holder located at end of burner tube again. Remove any large particles of dust, dirt, lint or pet hair with a soft cloth or vacuum cleaner nozzle.
5. Blow air into primary air holes on orifice holder.
6. In case any large clumps of dust have now been pushed into burner, repeat steps 3 and 4.
   Clean pilot assembly also. A yellow tip on pilot flame indicates dust and dirt in pilot assembly. There is a small pilot air inlet hole about 2″ from where pilot flame comes out of pilot assembly (see Figure 43). With unit off, lightly  blow air through air inlet hole. You may blow through a drinking straw if compressed air is not available.
