Introduction
PELLET QU LITY:
Pellet quality is important, please read the following:
Your pellet stove has been designed to burn wood pellets only. Do not use any other type of fuel, as this will
void any warranties stated in this manual.
The performance of your pellet stove is greatly affected by the type and quality of wood pellets being burned.
s the heat output of various quality wood pellets differs, so will the performance and heat output of the pellet
stove.
CAUTION: It is important to select and use only pellets that are dry and free of dirt or any impurities such as
high salt content. Dirty fuel will adversely affect the operation and performance of the unit and will void the
warranty. The Pellet Fuel Institute (P.F.I.) has established standards for wood pellet manufacturers. We
recommend the use of pellets that meet or exceed these standards. Please use a recommended pellet type.
P.F.I. PELLET ST ND RDS:
Fines (fine particles)......by weight: no more than 0.5% maximum through a 1/8” screen
Bulk Density..................40 pound per cubic foot minimum Siz e: 1⁄4” to 5/16” diameter 1⁄2 to 11⁄2” long maximum
sh Content.................1% maximum (Premium grade)..................3% maximum (Standard grade)
Moisture Content..........8% maximum
Heat Content................approximately 7,500-9,000 BTU per pound
PELLET FEED RATES: Due to different fuel densities and sizes, pellet feed rates may vary. This may require
the air intake damper setting (located where the intake air pipe meets the combustion chamber) to be adjusted.
To access, remove left rear panel by removing wing screws inside hopper. Increase airflow if the flame is
orange and lazy, and decrease airflow if pellets are “jumping” around or out of the burn pot. DO NOT OVER
FIRE. The adjustment range of the damper must not be altered for any reason. Since stove supplier has no
control over the quality of pellets that you use or installation and heating demands, we assume no liability for
your choice in wood pellets or the stove’s performance. Store pellets at least 36” (1 m) away from the pellet
stove in a dry place.
SHES:
Disposed ashes should be placed in a metal container with a tight fitting lid placed on a non-combustible floor
or on the ground, well away from all combustible materials pending final disposal. If the ashes are disposed of
by burial in soil or otherwise locally dispensed, they should be retained in the closed container until all cinders
have been thoroughly cooled.
The ash content of the fuel and operation of your stove will directly determine the frequency of cleaning. The
use of high ash fuels may result in the stove needing to be cleaned daily. low ash fuel may allow longer

Page 6 / 31
intervals between cleaning.
CLINKER CLE NING:
Clinkers are silica (sand) or other impurities in the fuel that will form a hard mass during the burning process.
This hard mass will block the airflow through the burn pot and affect the performance of the stove. ny fuel,
even approved types, may tend to clinker. Check the burn pot daily to ensure that the holes are not blocked
with clinkers. If they become blocked, remove the burn pot (when the unit is cold) and clean/scrape the
clinkers out. Clean the holes with a small pointed object if required.
ELECTRIC L:
The use of a surge protector is recommended and the stove must be grounded. The electrical cord should be
connected to a standard 11 5 volt, 15 or 20 , 60 hertz electrical outlet. Do not run cord under the appliance,
keep accessible and clear of any hot surfaces or sharp edges. If the power cord should become damaged, a
replacement power cord must be purchased from the manufacture or a qualified dealer. The stove’s
maximum power requirement is 520 watts (4.5 amps).
GL SS:
Do not abuse the glass by striking or slamming the door. Do not attempt to operate the stove with broken
glass. The stove uses ceramic glass. Replacement glass must be purchased from a qualified dealer. We are
not liable for glass purchased independently. Keep glass clean for better viewing and heat radiation.
FL MM BLE LIQUIDS:
Never use flammable liquid such as gasoline, gasoline-type lantern fuel, kerosene, charcoal lighter fluid, or
similar liquids to start or “freshen up” a fire in the heater. Keep all such liquids well away from the heater
while it is in use.
SMOKE DETECTOR:
Smoke detectors should be installed and maintained in the structure (home) when installing and operating a
pellet burning appliance.
OPER TION: The ash pan and door must be closed securely for proper and safe operation of the pellet stove.
lso ensure all gaskets on the door are checked and replaced when necessary.
KEEP ASH PAN FREE OF RAW FUEL. DO NOT PLACE UNBURNED OR NEW PELLET FUEL IN ASH
PAN AS A FIRE IN THE ASH PAN MAY OCCUR.
INST LL TION
Be sure to maintain the structural integrity of your home when passing a vent through walls, ceilings, or roofs
and use only listed type “L” or “PL” pipe and fittings. It is recommended that the unit be secured into its position
in order to avoid any displacement. Do not use makeshift compromises during installation.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT. DO NOT
CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
FRESH IR INT KE:
n outside fresh intake air supply is optional but must be used for all units installed in mobile and air tight
homes or where required by local codes. Consider all large air moving devices when installing your unit and

Page 7 / 31
provide room air accordingly. Limited air for combustion may result in poor performance, smoking and other
