Air Wash
To inhibit buildup of soot on the door glass, air
is delivered to the glass through an air wash
system located in the doorframe surrounding
the glass.
Auger
It transfers the fuel from the hopper to the feed
chute to deliver pellets to the UltraGrate™.
Auger Motor
Drives the Auger. Motor specifi cations are: .4
Amp, 1.1 RPM (revolutions per minute).
Blower, Room Air (Convection)
The blower function is to transfer the heat from
the appliance to heat the room air.
Blower, Exhaust (Draft Inducer/combustion)
It has a radial impeller to deliver more air to the
UltraGrate™. It pulls air into the UltraGrateby
creating a negative pressure. This is done by
extracting the exhaust gases out of the fi rebox
and pushing the exhaust downstream to the
fl ue exit.
Heat Select Button
This is the heat output control button. It controls
power to the feed system - auger motor and
exhaust blower. Use the heat select button to
adjust to any of the three feed rate settings
(which controls the burn rate).
Photoeye
The photoelectric eye that senses the fl ame, or
lack of. It is designed to signal the control board
to discontinue power to the auger motor if it
fl ame is not sensed in the UltraGrate.
Pressure Switch
A safety device used to shut off the feed system
(auger motor) if there is too much back pres-
sure in venting system. Some possible causes
are as follows:
• The venting system is obstructed.
• High altitude or other misc. environmental
conditions affecting exhaust fl ow.
• Improper venting system.
UltraGrate (Burn Grate)
This is where combustion occurs and may be
referred to as the “Burn Grate”.
Thermal Switch, High Limit (L250-30F, N/C)
There are 2 of these thermal switches on this
model. If a temperature reaches 250° F., the
high limit auto reset will “trip” and stop the fl ow
of electricity to the auger motor. The thermal
switches will not automatically reset until it has
cooled below 220° F).
Thermal Switch for Room Air Blower – This
thermal switch is located on the room air
blower jacket and is designed to detect an
overfi re condition.
Thermal Switch for Combustion Air Inlet
– This thermal switch is located on the
combustion air inlet and is designed to
detect reversed fl ow. 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 combustion air inlet, the
heat from the exhaust will result in heat
activation of this thermal switch.
Door Switch
(Profi le
®
30 FS-2 and Profi le 30 INS-2)
If the door is opened during operation (on model
Profi le 30 FS-2 and Profi le 30 INS-2), this switch
disconnects power to the auger motor resulting
in the unit shutting down.
Hopper
The hopper is where the pellets are stored.
