important operating and maintenance instructions
that you will need at a later time. Always follow the
instructions in this manual.
This appliance is designed for the use of pelletized fuel
that meet or exceed the standard set by the Pellet Fuel
Institute(PFI). The use of other fuels will void warranty.
Never use gasoline, gasoline-type lantern fuel,
kerosene, charcoal lighter fl uid, or similar liquids to start
or ‘freshen up’ a fi re in this stove. Keep all such liquids
well away from the stove while it is in use.
A working smoke detector must be installed in the same
room as this product.
Do not unplug the stove if you suspect a malfunction.
Turn the ON/OFF SWITCH to ‘OFF’ and contact your
dealer.
Your stove requires periodic maintenance and cleaning
(see “MAINTENANCE ”). Failure to maintain your stove
may lead to improper and/or unsafe operation.
Disconnect the power cord before performing any
maintenance! NOTE: Turning the ON/OFF Switch to
“OFF” does not disconnect all power to the electrical
components of the stove.
Never try to repair or replace any part of the stove un-
less instructions for doing so are given in this manual.
All other work should be done by a trained technician.
Do not operate your stove with the viewing door
open. The auger will not feed pellets under these
circumstances and a safety concern may arise from
sparks or fumes entering the room.
Allow the stove to cool before performing any maintenance
or cleaning. Ashes must be disposed in a metal container
with a tight fi tting lid. The closed container of ashes should
be placed on a non-combustible surface or on the ground,
well away from all combustible materials, pending fi nal
disposal.
The exhaust system should be checked monthly during
the burning season for any build-up of soot or creosote.
Do not touch the hot surfaces of the stove. Educate all
children on the dangers of a high-temperature stove.
Young children should be supervised when they are in
the same room as the stove.
The hopper and stove top will be hot during operation;
therefore, you should always use some type of hand
protection when refueling your stove.
A power surge protector is required. This unit must be
plugged into a 110 - 120V, 60 Hz grounded electrical
outlet. Do not use an adapter plug or sever the grounding
plug. Do not route the electrical cord underneath, in front
of, or over the heater. Do not route the cord in foot traffi c
areas or pinch the cord under furniture. Do not plug into
a GFI outlet.

FUEL CONSIDERATIONS
Your pellet stove is designed to burn premium hardwood pellets that comply with Association of Pellet Fuel Industries
standards. (Minimum of 40 lbs density per cubic ft, 1/4” to 5/16” diameter, length no greater than 1.5”, not less than
8,200 BTU/lb, moisture under 8% by weight, ash under 1% by weight, and salt under 300 parts per million). Pellets that
are soft, contain excessive amounts of loose sawdust, have been, or are wet will result in reduced performance.
Store your pellets in a dry place. DO NOT store the fuel within the installation clearances of the unit or within the space
required for refueling and ash removal. Doing so could result in a house fi re.

Installation
VENTING REQUIREMENTS
Install vent at clearances specifi ed by the vent manufacturer.
Do not connect the pellet vent to a vent serving any other appliance or stove.
Do not install a fl ue damper in the exhaust venting system of this unit.
The following installation guidelines must be followed to ensure conformity with both the safety listing of this stove and
to local building codes. Do not use makeshift methods or compromise in the installation.
IMPORTANT! This unit is equipped with a negative draft system that pulls air through the burn pot and
pushes the exhaust out of the dwelling. If this unit is connected to a fl ue system other than the way explained
in this manual, it will not function properly.
MAXIMUM VENTING DISTANCE
Installation MUST include at least 3-feet of vertical pipe outside the home. This will create some natural draft to reduce the
possibility of smoke or odor during appliance shutdown and keep exhaust from causing a nuisance or hazard by exposing
people or shrubs to high temperatures. The maximum recommend vertical venting height is 12-feet for 3-inch type “PL”
vent. Total length of horizontal vent MUST NOT exceed 4-feet. This could cause back pressure. Use no more than 180
degrees of elbows (two 90-degree elbows, or two 45-degree and one 90-degree elbow, etc.) to maintain adequate draft.
PELLET VENT TYPE
A UL listed 3-inch or 4-inch type “PL” pellet vent exhaust system must be used for installation and attached to the pipe
connector provided on the back of the stove (use a 3-inch to 4-inch adapter for 4-inch pipe). Connection at back of
stove must be sealed using Hi-Temp RTV. Use 4-inch vent if the vent height is over 12-feet or if the installation is over
2,500 feet above sea level.
We recommend the use of Simpson Dura-Vent® or Metal-Fab® pipe (if you use other pipe, consult your local building
codes and/or building inspectors). Do not use Type-B Gas Vent pipe or galvanized pipe with this unit. The pellet vent
pipe is designed to disassemble for cleaning and should be checked several times during the burning season. Pellet
vent pipe is not furnished with the unit and must be purchased separately.
PELLET VENT INSTALLATION
The installation must include a clean-out tee to enable collection of fl y ash and to permit periodic cleaning of the exhaust
system. The clean-out tee must be installed at the base of the vertical section, not in horizontal section. 90-degree
elbows accumulate fl y ash and soot thereby, reducing exhaust fl ow and performance of the stove. Each elbow or tee
reduces draft potential by 30% to 50%.
All joints in the vent system must be fastened by at least 3 screws, and all joints must be sealed with Hi-Temp RTV
silicone sealant on the inside and high temperature tape on the outside to be airtight. The area where the vent pipe
penetrates 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.
Vent surfaces can get hot enough to cause burns if touched by children. Noncombustible shielding or guards may be
required.
PELLET VENT TERMINATION
Do not terminate the vent in an enclosed or semi-enclosed area, such as; carport, garage, attic, crawl space, under a
sundeck or porch, narrow walkway, or any other location that can build up a concentration of fumes.
The termination must exhaust above the outside air inlet elevation.
The termination must not be located where it will become plugged by snow or other materials.
Do not terminate the venting into an existing steel or masonry chimney.
