What Prevents Gas Buildup
Your heater has a high technology gas valve in combination with safety sensors which prevent
any gas from building up. It also has a pilot light inside the firebox, which is a proven method
for preventing gas buildup.
While the main burner is off
There is a thermopile directly next to the pilot light which can sense if the pilot is still lit. If the
pilot goes out, this thermopile will no longer generate electricity which will cause the gas valve
to automatically shut off all gas to the unit. This prevents the pilot light from spilling gas into
the firebox.
While the main burner is on
The pilot light insures that the gas ignites inside the firebox, and that no gas builds up. In the
unlikely case of the vent blocking, there is a sensor which will sense any backdrafts or over-
heating. This sensor will signal the gas valve to shut off all gas to the unit if the vent is blocked.
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.
Spillage Sensor
This device detects if any flue gases spill
into the room. If it senses any spillage, the
gas valve automatically shuts off all gas
(the heater will then need to be restarted).
Gas Valve
This high technology valve automatically shuts off
all gas if it does not receive a signal from the
thermopile, door, or spillage sensor. If any
component is damged or sensing a malfunction, or
if the wiring is damaged, it will shut off all gas.
Pilot Light
The pilot light is
a time-proven
component that
eliminates the
possibility of
gas buildup
inside the
firebox.
Thermopile
The thermopile generates a small amount of
electricity. If the pilot does go out, the gas
valve automatically shuts off all gas (the
heater will then need to be restarted).
External Shut
Off Valve
This valve is
provided to shut
off gas to the
heater during
maintenance
procedures.
