CARE AND OPERATION

Fuel Delivery Rate
The Heat output button manages the fuel delivery rate by
controlling the amount of time the auger motor will run (Set-
tings:
1 = Low, 2 Medium Low, 3 Medium, 4 Medium High, 5
High).
PRE-LIGHTING INSTRUCTIONS
During an initial start-up, or in the case where the hopper
has run out of fuel, it will be necessary to prime the au-
ger feed system.
To prime the auger feed tube:
1. Fill the hopper with recommended pellet fuel and
plug the stove into the wall outlet.
2. Press the START button on the control board to turn
on both blowers (the room air blower and exhaust
blower will run at start up settings or position #3).
Press the AUGER ON/OFF button on the control
board to start the fuel feed. Next, press the Heat out-
put button to position #5 (maximum feed rate).
3. Look through the combustion chamber door and
when you see the first pellets dropping into the Ul-
traGrate
TM , the auger is then fully primed. It will take
10 to 15 minutes to prime the auger.
4. Once the auger is primed, press the AUGER
ON/OFF button to turn off auger.
STARTING YOUR PELLET STOVE
1.
Make sure the auger is primed (see Pre-Lighting
Instructions above), then simply push the Start but-
ton on the control board to activate the igniter.
2. Press the AUGER ON/OFF button to the “ON” posi-
tion.
3. While the pellets will ignite on any heat output set-
ting, it is recommended that the Heat Output be set
to position #3. Pellets will start feeding into the Ul-
traGrate
TM and should begin to ignite in approxi-
mately seven minutes. The self-igniter will auto-
matically shut off after fifteen minutes.
4. After the pellets are burning well, press the HEAT
OUTPUT selector to the desired setting. Combus-
tion air and the pellet fuel feed rate will adjust auto-
matically as the HEAT OUTPUT selector button is
pressed. The flame should be bright yellow in color
and there should be no evidence of soot formation
at the top of the flame. Press the BLOWER
SPEED control to increase or decrease the desired
amount of room air from your stove.
5. If operating your stove with the wall thermostat,
adjust the HEAT OUTPUT selector button to the
desired demand mode (#2 through #5 on the HEAT
OUTPUT selector button). Next, adjust the wall
mounted thermostat to the desired heat and your
stove will automatically switch between a demand
mode and a pilot mode.
GENERAL OPERATING CONSIDERATIONS
Proper Burn Characteristics: Your flame should be
bright yellow under normal operation. If your flame be-
comes reddish/orange, your stove probably needs rou-
tine maintenance. Excessive amounts of fly ash build-up
in the UltraGrate
TM , clinkers in the UltraGrate TM , or leak-
age of air if the UltraGrate TM is not properly seated, will
starve the fire for air. (See ROUTINE MAINTENANCE
for information on cleaning the stove). If the problem
persists, review the trouble-shooting section at the end of
this manual.
Pellet Feed: The pellet feed system is designed to han-
dle a wide range of pellet sizes. Different pellets can
feed at considerably different rates. If the stove will not
stay lit at the minimum fuel feed setting, those particular
pellets may not be feeding fast enough. If this happens,
adjust the damper rod (on the side of the stove) in or out
to achieve a proper burn.
Pellet Size: You may notice a difference in the burn if
you change pellet fuel sizes. The bigger the pellet, the
slower it will feed and vice versa.
Long Burn Time: The stove may be safely operated on
a continuous basis, but it is recommended that it be
turned down overnight or when the room is vacated for
long periods of time.
TURNING OFF YOUR PELLET STOVE
Press the AUGER ON/OFF button to the “OFF” position.
This will turn the auger motor off and pellets will stop feed-
ing. Both blowers will continue to operate for a period of
time (up to 45 minutes) until the exhaust temperature cools
sufficiently. The blowers will automatically turn off at that
point.
Lighting Procedure Without Igniter: Start-up procedure
when Fastfire
 igniter has failed or been removed and
not replaced.
If your automatic ignition system should ever need trouble-
shooting, repair or replacement, please contact your au-
thorized Lennox Hearth Products dealer. Your stove can
be lit manually without using the automatic igniter in such
cases by following the procedure below.
