AIR WASH
To inhibit buildup of soot on the door glass, air is deliv-
ered to the glass through an air wash system located in
the doorframe surrounding the glass.
AUGER
It transfers the fuel down the burner tube into the firepot.
AUGER MOTOR
Motor specifications are: .4 Amp, 1 rpm (revolutions per
minute). It drives the auger to deliver fuel to firepot.
BLOWER, ROOM AIR (CONVECTION)
The blower function is to transfer the heat from the appli-
ance to heat the room air.
BLOWER, EXHAUST (DRAFT INDUCER/COMBUSTION)
It has a radial impeller to deliver more air to the firepot. It
pulls air into the firepot by creating a negative pressure.
This is done by extracting the exhaust gases out of the
firebox and pushing the exhaust downstream to the flue
exit.
DISCS, INLET & CONVECTION HIGH LIMIT
DISC, HIGH LIMIT (L250-30F, N / C)
There are 2 of these discs on this model. If a tempera-
ture reaches 250° F., the high limit auto reset will “trip”
and stop the flow of electricity to the auger motor. The
discs will not automatically reset until it has cooled below
220° F).
Disc for Room Air Blower – This disc is located
on the Room Air Blower jacket and is designed to
detect an overfire condition.
Disc for Combustion Air Inlet – This disc is lo-
cated on the combustion air inlet and is designed to
detect reversed flow. If negative pressure in the
dwelling (i.e. An extremely tight house which may
not supply adequate combustion and ventilation air)
causes the exhaust to pull back from the combus-
tion air inlet, the heat from the exhaust will result in
heat activation of this disc.
DISC, LOW LIMIT (Ceramic, F140-30F, N / O*)
This disc is designed to shut down the stove (auger mo-
tor and both blowers) if it does not sense the heat of a
fire.
HOPPER
The hopper is where the pellets are stored.
HEAT OUTPUT BUTTON
This is the main power button, which controls power to
the feed system auger motor and Exhaust Blower. It has
5 feed rate settings, which controls the burn rate.
PRESSURE SWITCH
The Positive Pressure Switch is located on the Exhaust
housing and is designed to shut down the auger motor in
the event of flue blockage. Some other possible causes
are as follows:
♦ The venting system is obstructed.
♦ High altitude or other misc. environmental conditions
affecting exhaust flow.
♦ Improper venting system.
ULTRAGRATE
TM
Burn grate receptacle in firebox where pellets are deliv-
ered by auger motor system and burned.
