CARE AND OPERATION
PAGE 24
Combustion Voltage Trim Steps:
1. Push button “twice” for access voltage calibration mode.
2. Identify the current calibration setting indicated by one
YELLOW LED bar.
3. Push the “HEAT” control button to adjust setting UP. Each
push raises the YELLOW LED bar & increases voltage 5%.
4. Push the “BLOWER” control button to adjust setting
DOWN. Each push lowers YELLOW LED bar decreasing
voltage 5%.
5. Push the calibration button once to lock in selected results.
Fuel Delivery Rate
The feed rate button manages the fuel delivery rate by controlling
the amount of time the auger motor will run as follows:

variations in line voltage.

Your pellet stove can be operated in either manual
or automatic mode. The manual mode is used
when operating without a thermostat. The auto-
matic mode is used when utilizing a wall thermo-
stat. 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 burn settings.
Initial Start-Up / Empty Hopper or Feed Tube:
During an initial start-up, or in the case where the hop-
per has run out of fuel, it will be necessary to prime the
auger feed system. The control board is set to deliver
fuel for approximately 2 1/2 minutes during start-up,
which, with a fully primed auger tube, will provide the
appropriate amount of fuel for ignition.
When first starting your pellet stove, it will be nec-
essary to prime the auger tube. To prime the auger
tube you need to first fill the hopper with pellets,
and press the ON button on the control board. Wait
approximately 2 1/2 minutes and turn the control
board OFF and then back ON again. Wait an addi-
tional 2 1/2 minutes (if necessary) and continue this
process until fuel begins to fall into the Ultra-
Grate. Remember, different brand fuels feed at
different rates.
Once fuel starts to enter the UltraGrate, turn the
stove OFF and then back ON. The auger tube should
now be primed and the stove should deliver enough
fuel for proper ignition. It may be necessary to follow
these procedures in the event that the hopper runs
completely out of fuel.
