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 burn grate.

AUGER MOTOR

Drives the Auger. Motor specifications are: .4 Amp, 1 rpm (revolutions per minute).

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 burn grate. It pulls air into the burn grate by creating a nega- tive pressure. This is done by extracting the exhaust gases out of the firebox and pushing the exhaust down- stream to the flue exit.

DISC, HIGH LIMIT (L250-30F, N / C)

There are 2 of these high limit discs on this model. If a temperature 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 de- tect 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.

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 3 feed rate settings, which controls the burn rate.

PHOTOEYE

The photoelectric eye that senses the flame, or lack of. It is designed to signal the control board to discontinue power to the auger motor if it flame 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 pressure in venting sys- tem. Some possible causes are as follows:

The venting system is obstructed.

High altitude or other misc. environmental conditions affecting exhaust flow.

Improper venting system.

ULTRAGRATE (BURN GRATE)

This is where combustion occurs and may be referred to as the "burn grate".
