COMPONENT DEFINITIONS
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, CONVECTION (ROOM AIR)
The blower specifications are: 150 CFM (cubic feet per
minute), .8 Amp, 2178 rpm (revolutions per minute).
The blowers function is to transfer the heat from the
appliance to heat the room air.
BLOWER, COMBUSTION (DRAFT INDUCER)
The blower specifications are: 95 CFM (cubic feet per
minute), 1.0 Amp, 2880 rpm (revolutions per minute). 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.
DISC, CONVECTION HIGH LIMIT (L250-30F, N / C)
If the temperature of the convection air chamber
reaches 250° F., the high limit auto reset will "trip" and
stop the flow of electricity to the auger motor. It will not
automatically reset until it has cooled below 220° F).
DISC, INLET HIGH LIMIT (L250-30F, N / C)
If negative pressure in the dwelling (ie. An extremely
tight house which may not supply adequate combustion
and ventilation air) causes the exhaust to pull back from
the combustion air inlet, the heat from the exhaust will
result in heat activation of this switch (trips at 250° F will
stop the flow of electricity to the auger motor. It will not
automatically reset until it has cooled below 220° F).
DOOR SWITCH (Profile
If the door is opened during operation (on model Profile
30 FS and Profile
power to the auger motor resulting in the unit shutting
down.
ULTRAGRATE    (BURN GRATE)
This is where combustion occurs.
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 draft fan. It has 3 feed
rate settings, which controls the burn rate.
PHOTOEYE
The photoeye is designed to signal the control board to
discontinue power to the auger motor) if it does not
sense a flame in the firepot.
PRESSURE SWITCH
The pressure switch is a safety device used to shut off
the feed system (auger motor) if there is too much back
pressure in venting system. Some possible causes are
as follows:
♦
The venting system is obstructed.
♦
High altitude or other misc. environmental condi-
tions affecting exhaust flow.
♦
Improper venting system.
