Understanding Your Pellet Stove
During the startup process of the ComfortBilt HP42 pellet stove, you can expect the following sequence of events:

1. Combustion blower turns on (“Igniting” displayed).
2. Igniter heats up.
3. Auger delivers pellets to the burn pot (some smoke may occur).
4.  Convection blower activates once the stove heats up (“Heating” displayed).
5. Both blowers continue running even after shutdown (“Fire off” displayed). 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. Adjusting the air damper between the approved ranges (75% to 100% open) may allow you to find the perfect combustion setting for your application. There is a mechanical stop to prevent closing
  of this damper beyond 75% open.

• The air damper is preset at 75% allowable air, which is preferable in most applications. Opening this damper when installed into a space with lower air availability, such as basements, may be beneficial.

• 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.

Before starting your ComfortBilt HP42 pellet stove, it is important to select the desired operating mode for optimal functionality. The stove offers four modes: Manual, Temp, Weekly, and Thstat.

1. Manual Mode: In this mode, you have control over the heating power level. You can adjust and set the
   level from 1 to 5 to achieve the desired heat output.

2. Temp Mode: In this mode, you can set the desired room temperature. The stove will automatically adjust the heating power level to maintain the selected temperature. Enabling the ECO option in the settings allows the stove to cycle on and off automatically to maintain the desired temperature.

3. Weekly Mode: This mode allows you to schedule the stove’s operation according to your preferences.
   You can program specific days and times for the stove to automatically operate. You can set different
   programs for each of the seven days of the week, with up to four periods per day.

4. Thstat Mode: This mode utilizes a simple wired thermostat to control the fire-on and fire-off cycles of the stove.
   To select the desired mode, use the mode select button on the controller. Pressing this button will cycle through the available operating modes. The current mode is displayed in the upper left-hand corner of the screen.
   It is crucial to choose the mode before turning on the stove. Attempting to change the mode while the stove is already burning may cause the stove to shut down, resulting in a 30-minute cool-down delay before restarting. It is not necessary to start the stove’s operation to select the mode. Locate the mode select button on the controller to make your mode selection.

• Manual Mode: In Manual Mode, you have the flexibility to adjust the heat levels of the ComfortBilt HP42 pellet stove, allowing you to increase or decrease the amount of heat it produces.

• To modify the power level in Manual Mode, use the “Scroll Up” or “Scroll Down” buttons on the control pad.

• Each press of these buttons will adjust the power level by one increment.

• Please note that Manual Mode enables you to directly control the heat output using a scale of 1 to 5 bars, rather than adjusting specific temperatures. For temperature control, you can refer to the Temp Mode.

• Temp Mode: In Temperature Mode, you have the ability to set your desired room temperature. The stove will automatically adjust the heat level to maintain the room temperature close to your desired setting.

• To adjust the “Call to” temperature, simply use the “Scroll Up” or “Scroll Down” buttons on the control pad. The current room temperature and the set “Call to” temperature will be displayed in the temperature display box on the screen.

• When the room temperature falls below the set “Call to” temperature, the stove’s heat power level will automatically increase to the maximum level of five.

• Once the desired temperature is reached and maintained for about a minute, the heat power level will return to one, remaining at that level until additional heat is required.

• Please note that in Temperature Mode, the stove will not shut off or go into standby. Instead, it will idle and continue producing a fire until the room temperature falls below the set “Call to” temperature. During idling, the heat power level will be indicated as level one on the display screen’s power level box. To enable the stove to cycle off and on automatically, make sure to turn on the ECO option in the “Settings” section.

• Weekly Mode: In Weekly Mode, you have the ability to schedule and control the operation of the stove during specific times and days throughout the week. You can set up to four different operation times for each of the seven days.

• When the stove is operating in Weekly Mode, it functions similarly to the “Temp” mode. As part of the weekly schedule program, you can also set a desired “call to” temperature for each scheduled period. For detailed instructions on programming the weekly schedule, please refer to the “Set Data” section.

• IMPORTANT: It is essential to set your weekly schedule in Weekly Mode before starting a fire. If you try to set a weekly schedule while the stove is already running in Manual or Temp modes, the schedule will not be set, and the screen will prompt you to wait until the stove is turned off

• and has cooled down before attempting to set the schedule again.

• Thstat Mode: Thstat Mode allows you to control the stove using a wired remote thermostat. However, please note that the stove will only operate in this mode if it is connected to a compatible thermostat.

• A thermostat acts as a temperature-activated switch. When the thermostat signals a demand for heat, you will see an “ASKED” message displayed on the screen. This indicates that the stove has received the request and will automatically ignite and start running to generate heat.

• Conversely, when the thermostat no longer requires heat, you will see a “NONE” message on the screen. In response, the stove will enter a fire off mode, allowing the fire to gradually die down. Eventually, the stove will transition into standby mode, ready for the next call for heat.

• Please ensure that your stove is properly connected to a thermostat for Thstat Mode to function correctly.

• Connecting a Thermostat: Connect the “Call for Heat” extension wires from the thermostat to the bottom circuit board.

• Open the right side or rear panel to access the circuit board.

• Remove the lid by removing the 4 Philips screws in the corners. (You can unscrew the bottom L bracket to make it easier to access the board).

• Connect the thermostat pigtail lead wire (sold separately) to the plug labeled “Level” as shown.

• Splice the pigtail wire into the existing thermostat wire.

• Connect thermostat wire to thermostat on the proper “Call for Heat” connections.

  • Priming is only required the first time the stove is lit, or after hopper has been emptied for cleaning and maintenance.
• Ready to start:
  • The stove is now ready to start. Remember to empty any extra pellets from the burn pot before igniting. (See Safety Startup Procedures)

Safety Startup Procedures

• Ensure Clean Burn Pot:
  Before initiating the ignition sequence, ensure that the burn pot is completely clean and free from any fuel residue or debris. Cleaning the burn pot helps prevent potential issues such as delayed ignition, excessive smoking, puffing starts, and the risk of creating large fires. Additionally, inspect and clear any obstructions from the air holes surrounding the burn pot to promote proper airflow and efficient combustion.

• Ensure Proper Burn Pot Seating:
  When placing the burn pot onto the cradle, make sure it is seated securely without any gaps or spaces that could allow air to escape. A tight seal between the burn pot and the cradle is vital for optimal combustion and to prevent air leakage, maximizing efficiency and heat generation.

• Secure Front Door:
  Check that the front door of the stove closes tightly and latches securely. Similarly, ensure the ash pan is properly seated with no gaps or misalignments. This maintains efficiency and prevents any disruptions.

• Check and Fill the Hopper:
  Confirm that the hopper is fully filled with pellets, reaching the underside of the fill lid. Ensure the hopper lid closes tightly, and check that the hopper lid switch engages correctly when closed. The switch ensures the auger operates only when the hopper lid is securely in place.

• Select Mode & Start Ignition:
  Choose the desired mode on the stove, then press the On/Off button to initiate the stove’s operation.
  Listen for the sound of the exhaust fan engaging and observe the pellets falling into the burn pot. Within a few minutes, the igniter will reach high temperatures, igniting the pellets and producing a fire.

• Monitor the Ignition Cycle:
  During the ignition cycle, it is crucial to closely monitor the stove until the flame is fully established. Never leave the stove unattended during this time. If you notice excessive smoke or if the fire takes longer than

• 5 minutes to establish, follow these steps:
  Press the On/Off button once to turn off the stove. (OFF will display in the lower right corner)
  Press and hold the On/Off button for 5 seconds. (IGNITING will change to display FIREOFF in the phase line at the upper left corner) Allow the stove to fully cool and then restart the ignition process from step 1, which is cleaning the burn pot.

Notice: Ignition sequences require an empty burn pot. Fuel and residue in the burn pot can cause delays in ignition, excessive smoking, puffing starts, and oversized fires.

Characteristics of a Good Flame
A properly functioning flame exhibits specific characteristics. Look for an active torch-like flame with a bright yellow center. Additionally, observe streaks of blue near the bottom of the burn pot, indicating sufficient airflow pressure. The resulting ash should reduce to a fine light gray powder.
Conversely, signs of improper combustion include gritty brown ash and fuel being expelled from the pot before complete reduction. These indicate excessive air pressure under the burn pot.
Dark or black ash and sluggish, darker flames suggest an air shortage.

Here’s what to expect at different heat levels:

1. Bar: At this level, the fire height may vary due to a lighter feed schedule. On average, the top of the flame should be slightly above the lip of the burn pot.
2. Bars: The fire at this level should form a relatively stable torch, reaching approximately halfway up the chamber.
3. Bars: The flame at this level will be tall, with the tops of the flames extending to about the underside of the heat tubes.

Information Screen
At any time, you can access the Running Information screen by pressing the Information button once.
