COMPONENT DEFINITIONS

•Air Wash

A small slot in the door that allows room air to be pulled into the firebox and pours over the inside surface of the door glass to inhibit the build up of soot.

•Auger

A motor powered screw device that transfers the fuel from the hopper to the feed chute to deliver pellets to the UltraGrate™.

•Auger Motor

Drives the Auger. Motor specifications are: 0.5 Amp, 1.25 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 (Combustion)

It has a radial impeller to deliver more air to the UltraGrate™. It pulls air into the UltraGrate 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.

•Thermal Switches, High Limit

There are three of these high-limit thermal switches on this model. If a temperature reaches the high limit temperature, the reset switch will “trip” and stop the flow of electricity to the auger motor. The thermal switches will not reset until they have cooled below low reset temperature).

-Auto Reset Thermal Snap Switch for Room Air Blower (L250- 30F, N/C*) – This switch will trip at 250° F and will automatically reset when it reaches a temperature of 220° F. This switch is located on the room air blower jacket and is designed to detect an overfire condition.

-Auto Reset Thermal Snap Switch for Combustion Air Inlet (L250-30F, N/C*) This switch will trip at 250° F and will auto- matically reset when it reaches a temperature of 220° F. This switch is designed to detect reversed flow or excessive heat in the ashpan area. This switch is located on the firebox base behind the convection jacket, directly above the ashpan. This switch is most easily accessed by removing the ashpan

-Manual Reset Thermal Snap Switch for Feed Chute (L300-145F, N/C*) This switch will trip at 300° F and will not be resettable until it reaches a temperature of 155° F. This switch is designed to detect if heat from the fire is approaching a path toward the hopper. If this switch trips it must be manually reset. To reset, open left side access door (facing stove), locate switch on the side of the auger tube and press the red button in the center until it clicks into the reset position.

•Thermal Switch, Low Limit (Ceramic, F140-20F, N/O*) - This "proof of fire" switch will close at 140° F and will not open until it reaches a temperature of 120° F. This switch is located on the combustion blower (behind the right side panel). It is designed to shut down the stove (auger motor and both blowers) if it does not detect the heat of a fire at the end of the initial startup period.

•Hopper Lid Switch

It is located on the left hinge area inside the hopper. It detects whether the hopper lid is open and will turn off the auger motor if the hopper lid is not properly closed. When opening the hopper when refueling, do not allow the hopper lid to remain open too long or the fire may extinguish. NEVER DISCONNECT OR BYPASS THIS SWITCH FOR

ANY REASON.

•Hopper

The hopper is where the pellets are stored.

•Heat Output Button

It controls power to the feed system - auger motor and combustion blower. Use the heat output button to adjust to any of the five feed rate settings (which controls the burn rate).

•Pressure Switch

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 conditions affecting exhaust flow.

• Improper venting system.

The Pressure Switch is located inside the right access door right next to the combustion blower.

•UltraGrate (Burn Grate)

This is where combustion occurs and may be referred to as the “Burn Grate”.
