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 auger feed system.
To prime the auger feed system:
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 start the fuel feed.
Next, press the "HEAT OUTPUT" button to position #5 (maximum feed
rate).
3. Look through the combustion chamber door and when you see the first
pellets dropping into the UltraGrate™, 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 "STOP" button to turn off the auger
(LED will go off).
Starting Your Pellet Stove
1. Make sure the auger is primed (see Pre-Lighting Instructions on this
page), then simply push the "START" button on the control board to
activate the Fastfire™ igniter.
2. While the pellets will ignite on any heat output setting, it is recommended
that the "HEAT OUTPUT" button be set to position #3. Pellets will start
feeding into the UltraGrate and should begin to ignite in approximately
three to seven minutes. The Fastfire igniter will automatically shut off
after 8 minutes.
3. After the pellets are burning well, press the "HEAT OUTPUT" selector
to the desired setting. Combustion air and the pellet fuel feed rate will
adjust automatically as the "HEAT OUTPUT" 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
button to increase or decrease the blower speed to the desired level
4. If operating your stove with the wall thermostat, adjust the "HEAT
OUTPUT" button to the desired demand mode (#1 through #5 on the
"HEAT OUTPUT" button). Next, adjust the wall mounted thermostat
to the desired room temperature and your stove will automatically
switch between a demand mode and stand-by mode.
Notes:
Cold Start - When the "START" button is pressed when the appliance
is cold, voltage will bypass its normal circuit through the low limit
thermal switch (for 20 minutes to allow adequate time for the low limit
thermal switch to heat [140° F min.] which will close the circuit). The
combustion and convection blowers will start at maximum speed.
After approximately 10 seconds both blowers will default to settings
they were at after the last shut down was completed (indicated by
LED's #1 to #5). The Fastfire igniter will operate for approximately 8
minutes. The auger will turn continuously for a predetermined dura-
tion at the respective Heat Output Settings, followed by the normal
operating mode.
Re-Fueling While in Operation
1. Open hopper lid and fill hopper with pellets.
2. Make sure the hopper lid is completely closed.
3. Check to make sure the stove remains lit.
4. If the flame goes out, press the "start" button on the control panel to
re-ignite.
Caution: Failure to ensure pellets in the UltraGrate remain
burning after re-fueling may result in smoke escaping from
the unit.
General Operating Considerations
Proper Burn Characteristics: Your flame should be bright yellow under
normal operations. If your flame becomes reddish/orange, your stove
probably needs routine maintenance. Excessive amounts of fly-ash build-
up in the UltraGrate, clinkers in the UltraGrate, or leakage of air if the
UltraGrate is not properly seated, will starve the fire for air. (See Routine
Maintenance for information on cleaning the stove). If the problem per-
sists, review the troubleshooting section at the end of this manual.
Manual and Automatic Operation
Your pellet stove can be operated in either the manual or automatic mode.
The manual mode is used when operating without a wall thermostat. The
automatic mode is used when utilizing a wall thermostat. When utilizing the
thermostat capability, the burn time can be extended dramatically depending
on thermostat setting. Note: It is normal for some ash to build up on the
inner glass surface at the lower Heat Output settings.
Manual Operation
Pressing the "START" button will initiate the start-up cycle. The auger
LED will be green to indicate the “on” status. The blower speeds and
pellet feeds are fixed during this time to provide appropriate ignition.
The Fastfire igniter system will light the pellets fed to the UltraGrate, after
about 3 minutes. After the start-up cycle, your stove will be in the run
mode. At this point the stove will operate with the heat output ("HEAT
OUTPUT" button) and blower settings ("BLOWER" button) selected. These
settings can be selected either during or after the start-up cycle. Pressing
the "STOP" button during the run mode will initiate the shut down cycle
(feeding LED will go off). The pellets will stop feeding and the blowers
will run at a fixed speed for approximately 10 minutes. At this point your
stove is safely shut down. The stove can be restarted by pressing the
"START" button during the shut down cycle.
Automatic Operation
Your stove is capable of running in an automatic mode with the use of
a wall thermostat.
For the wall thermostat to control the operation of the stove, set it to a
temperature that will put it in the demand mode (calling for heat). The
thermostat will establish either a demand mode or a stand-by mode.
The thermostat should be set for the desired room temperature. If the
room temperature drops below the level on the thermostat the stove
will automatically begin the start-up cycle, as explained in the Manual
Operation section.
Once the start-up cycle is completed the stove will operate at whatever
heat and blower setting you have selected. For best operation under
thermostat control, the medium or high settings are recommended. When
the desired room temperature is reached the stove will automatically go
into the shut down cycle. The pellet feed will stop and the blowers will
continue for a controlled time allowing safe shut down of your stove. All
lights will remain on when the thermostat is open. The "HEAT OUTPUT"
and "BLOWER" settings can be changed at any time, but only take affect
during the run mode. When the temperature in the room drops to the
level set at the thermostat, the stove will again begin the start-up cycle
and resume automatic operation in the demand mode.
Note: If the "START" button is pressed while the thermostat is in the
standby mode the stove will not restart until the thermostat closes (call-
ing for heat).
