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.
BURNING PELLET FUEL
Ashes need to be removed from the stove
periodically. See Normal Care & Maintenance
section for cleaning procedures.
Due to the nature of pellet fuels, this stove will
require attention periodically. Regular cleaning is
an important part of burning pellet fuel.
PELLETS
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" to 1/2", 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.
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. 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. Keep fuel dry.
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 will void the
warranty. The Pellet Fuel Institue (PFI) has
established standards for wood pellet
manufactuerers. Only use pellets that meet or
exceed PFI standards for premium fuels.
7
CLINKERS
Impurities, such as silica (clinkers), will need to be
regularly cleaned and removed from the pellet
stove. Clinkers will form a hard mass and block
airflow through the pot liner. High quality fuels will
usually result in fewer clinkers.
Pellet fuel quality can greatlly fluctuate. The unit
was tested with premium grade pellets. You
cannot use a lesser grade, but higher grades can
be used.
Do Not Burn:
Garbage
Lawn clippings or yard waste.
Materials containing rubber, including tires.
Materials containg 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
Paper products, cardboard, plywood, or
particleboard. The prohibition against using
these materials does not prohibit the use of fire
starters made from paper, cardboard, saw dust,
wax and similar substances for the purpose of
starting a fire in an affected wood heater.
Burning these materials may result in the release of
toxic fumes or render the heater ineffective and
cause smoke.

AUTOMATIC SAFETY FEATURES
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 120 degrees
Fahrenheit when power is restored, the exhaust
and convection fans will continue to run until the
stove cools. See lighting instructions to restart
stove.
POWER OUTAGE
OVERHEATING
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 200 degrees Fahrenheit,
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. See Start-
Up.
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 3-5 minutes of pressing
the On/Off button. As pellets fill the burn pot and
ignite, outside air is drawn across the fuel and
heated during the combustion process with is then
pulled across the heat exchange tubes by the
exhaust motor. As the stove reaches operating
temperature, the room air is then circulated around
the heat exchange tubes by a room air 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. Also, the doors must remain closed
while in operation and the seals on the doors must
be properly maintained.
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

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. 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 required.
PELLET VENT INSTALLATION
Vent termination MUST exhaust above the
elevation of the air inlet. It is recommended to
install at least 3 feet of vertical pellet vent pipe.
This vertical pipe will create some natural draft to
reduce the possibility of smoke or odor during
appliance shutdown, and will keep exhaust from
causing a nuisance or hazard from exposure to
high temperatures.
The installation must include a clean out tee to
enable the collection of fly ash and to permit
periodic cleaning of the exhaust system. Total
length of horizontal vent must not exceed 10 feet.
The maximum recommended vertical venting
height is 18 feet.
All joints for pellet vent are required to be
fastened with at least three screws and
all connections (including adapters,
elbows, etc...) should be sealed airtight
by injecting 500° F RTV silicone into the
gap between sections.
The area where the vent pipe goes
through to the exterior of the home must
be sealed with silicone or other means to
maintain the vapor barrier between the
exterior and the interior of the home.
12
WARNING
Do Not connect this unit to a chimney flue that
services another appliance.
Do Not install a flue damper in the exhaust
venting system of this unit.
Do Not connect directly to a masonry chimney.
Do Not terminate vent in any enclosed or semi-
enclosed area, such as; Carport, garage, attic,
crawl space, under a sun deck or porch, narrow
walkway, or any location that can build up a
concentration of fumes such as a stairwell,
covered breezeway, etc...
CAUTION
Vent surfaces can get hot enough to cause burns if
touched. Non-combustible shielding or guards may
be required.
Pellet vent must maintain minimum clearances
to combustibles specified by vent manufacturer.
Install vent at clearances specified by the vent
manufacturer.
All venting joints, whether vertical or horizontal,
should be made gas tight with recommended
sealants.
WARNING
Never shut the stove down by unplugging it from
the power source.
Never shut the stove down from by switching off
the main power switch on the rear of the stove.

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.
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.
Figure 8: Vent Termination
A: 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.
NOTE: May not vent into covered walkway or breezeway.

14
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.
NOTE: In order to achieve optimum
performance, it is recommended that you keep
the vent as short as possible, especially in
regards to the horizontal run.
The vent must have a support bracket
every 5' of pellet vent when on the exterior
of the structure.
The vent height and run must not exceed
the distance as illustrated in diagram
Figure 9.
Venting into the lighter shaded area may
require combustion motor voltage
adjustments and/or inlet air adjustments
(intake).
See Figure 9
Figure 9: Venting and combustion motor
voltage adjustment chart

OUTSIDE AIR CONNECTION
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 of 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 up the air inlet during a power outage.
Blockage, excessive length (more than 6-8 ft),
or extra bends in the air intake could lead to
starvation of combustible air to the stove.
15
MOBILE HOME
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.
Stove must be electrically grounded to the steel
chassis of the mobile home, unless 3-prong or
GFCI power outlets are provided.
All vertical chimney vents must have wall
supports.
All exhaust systems must have a spark arrestor.
Check with local building officials to see if other
codes may apply.
Structural integrity of the floor, wall and
ceiling/roof must be maintained.

WARNING
Do not connect to any air distribution duct or
system.
Do not install in a sleeping room.
CAUTION
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 pressure (vacuum) switch may shut off the
operation of the pellet stove.
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. A
disadvantage of supplying interior room air to the
burn pot is that the room air used by the burn pot
(and sent out to the exhaust pipe) must be
replaced by air drawn through windows, doors,
and cracks. Using interior air is not recommended
in newer houses that are tightly sealed. Air drawn
in by the room blower is always interior room air
and should be the coolest air in the living space.
Stoves typically work best when placed on the
lower level of the home, and located so that all the
air in the space is freely available to the stove's
heat exchanger.
