INTRODUCTION Congratulations on your investment in quality. We have worked hard to ensure that this pellet stove meets the highest standards for usability and durability. With proper care, your stove will provide many years of dependable service. Please read entire manual before installation and use. Complies with the ASTM E1509, (UM) 84-HUD, ULC/ORD-C-1482. U.S. Environmental Protection Agency Certified to comply with 2020 particulate emission standards using pellet fuel.
UNDERSTANDING YOUR STOVE AUTOMATIC SAFETY FEATURES 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.

INSTALLATION It is recommended that the stove be installed and serviced by an authorized professional. Proper installation of this stove is necessary for safe and efficient operation. Installing this product improperly may result in a house fire and/or personal injury. STOVE PLACEMENT 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.
CLEARANCES TO COMBUSTIBLES NOTE: These are minimum clearances to combustible walls. 3" 2 " 6" 3" Figure 4: Corner Insallation through wall Figure 5: Straight Insallation through wall 3" 2" 2" 3" Figure 6: Corner Insallation interior vertical vents 6" Figure 7: Straight Insallation interior vertical vents NOTE: 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.
VENTING Before venting, consult vent manufacturer's specifications and recommendations for all venting installations. The following installation guidelines must be followed to ensure conformity with both the safety listing of this stove and to local building codes. TYPE OF VENT The pellet venting pipe (also known as L vent) is constructed of two layers with air space between the layers.
PELLET VENT TERMINATION CLEARANCE 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. SEE FIGURE 8 Must have an approved cap (to prevent water from entering) or a 45 degree downturn with rodent screen.
VENTING THE PELLET STOVE 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 exceed 180° of elbows, you must use 4" venting pipe.
OUTSIDE AIR CONNECTION The efficiency of ComfortBilt pellet stoves can be impacted by the temperature of the air supplied to the burn pot, and the temperature of the air that is drawn past the heat exchange tubes to heat the room. When exterior air supplied to the burn pot is extremely cold, slightly more energy is required to burn pellets at optimum temperatures.

MAINTENANCE NORMAL CARE AND MAINTENANCE A majority of all problems with pellet stoves are either directly or indirectly related to general maintenance and cleaning issues. 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. GLASS FRONT DOOR Only clean the glass when the glass is cool.
DAILY MAINTENANCE BURN POT Remove and clean the burn pot daily. Make sure all of the airflow holes in the burn pot are unobstructed. Using a small metal pick or drill bit can aid you if these get plugged through general use. Every time the hopper is filled with fuel, the burn pot should be emptied. In order to empty the burn pot, lift it out of the cradle and dump it directly into the ash pan. Be sure any build-up is removed when clearing the airflow holes.
CONTINUING MAINTENANCE REAR AIRFLOW/EXHAUST CHAMBER In addition to daily and weekly maintenance tasks, the exhaust chamber covers should be removed and the entire chamber vacuumed thoroughly once every 1.5 tons of pellets burned. 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. There are two total chamber covers.
