How this Heater Works
Warning This heater was designed with safety as the primary concern. Many of the components inside this heater are for safety purposes. Therefore, only certified gas service technicians should service this heater.
What Turns the Main Burners On and Off
This heater uses a millivolt system to control its operation (a millivolt is a very small amount of electricity). The thermopile and thermocouple generate electricity when heated by the pilot flame. This electricity is used to operate the gas valve. Without enough electricity, the gas valve will not turn on. That is why when starting the pilot the gas control knob has to be pressed in long enough for the thermocouple to heat up and generate enough electricity. The thermopile provides power for the ON/OFF switch, remote control, or thermostat (see the illustration below). Because the thermopile generates the electricity needed to turn the heater on and off, this heater can be operated when the power is out (although the blower will not run).

What Prevents Gas Buildup
•This appliance utilizes a
•The thermocouple (next to the pilot) senses when the pilot flame is lit. If the pilot flame goes out, this thermocouple no longer generates electricity, causing the gas valve to automatically shut off all gas to the heater, preventing the pilot or burner from spilling gas into the firebox.
Pilot Flame
The pilot flame is a
Gas Valve
This
External Shut Off Valve
This valve is placed on the gas line to shut off gas to the appliance during maintenance procedures.
Thermocouple
The thermocouple generates a small amount of electricity. If the pilot flame goes out, the gas valve automatically shuts off all gas.
Ceramic Glass
The glass in your heater is the most durable glass available. It has been tested to be extremely resistant to breakage from temperature changes.
