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 generates 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

+ Your fireplace utilizes a high-technology gas valve to prevent gas buildup. It also has a pilot flame
inside the firebox, which is a proven method for preventing gas buildup.
+ While the main burner is off 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 fireplace, preventing the pilot from spilling gas into the firebox.
+ While the main burner is on the pilot flame insures all gas ignites inside the firebox.
Pilot Flame
The pilot flame is a time-proven
component that eliminates the possibility
of gas buildup inside the firebox.
Therocouple
The thermocouple generates a small
amount of electricity. If the pilot flame
goes out, the gas valve automatically
shuts off all gas.

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
damged or sensing a malfunction, or if the
wiring is damaged, it will shut 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 and temperature changes.
