How this Fireplace Works

This fireplace was designed with safety as the primary concern. Many of the components inside this
fireplace are for safety purposes. Therefore, only certified gas service technicians should service this
fireplace.
What Turns the Main Burners On and Off
This fireplace 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 fireplace on and off, this fireplace can be operated when the power is out (although the blower will
not run).
When heated, the thermopile
generates electricity (a very small
amount measured in "Millivolts").
What Prevents Gas Buildup
This appliance utilizes a high-technology gas valve in conjunction with a pilot flame to ensure no gas builds
up inside the firebox.
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 from spilling gas into the firebox.
Pilot Flame
The pilot flame is a time-proven
component that eliminates the possibility
of gas buildup inside the firebox.
Thermocouple
The thermocouple generates a small
amount of electricity. If the pilot flame
goes out, the gas valve automatically
shuts off all gas.

Maintenance
This electricity is
used to operate the
main burners.
Gas Valve
This high-technology valve automatically
shuts off all gas if it does not receive a signal
from the thermocouple. If any component is
damaged or sensing a malfunction, or if the
wiring is damaged, it will shut off all gas.

The main burners
are switched on and
off using the
electricity generated
by the thermopile.
The ON/OFF switch,
remote control, or

the circuit to the main
burner.
External Shut Off Valve
This valve is placed on the gas line
to shut off gas to the appliance
during maintenance procedures.
