Stove Design
Many of the components within this gas stove are
designed specically for safety purposes. It is therefore
imperative that only certied gas service technicians
should service this appliance.
Burner Operation
A millivolt system controls the operation of this stove.
The thermopile and thermocouple generate electricity
when heated by the pilot ame. 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. Because the thermopile generates the
electricity needed to turn the replace on and off, this
stove can be operated when the power is out (although
the blower will not run).
Gas Build Up Prevention Feature
This appliance’s utilization of a high-technology gas
valve in conjunction with a pilot ame ensures that no
gas builds up inside the rebox.
The thermocouple (next to the pilot) senses when
the pilot flame is lit. If the pilot flames 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 rebox.
