Heater Component Function

Air Proving Switch (Classic 115)
Safety device used to insure that the proper air fl ow
is being achieved before the gas valve is opened.
Burner
Cast iron component used to channel gas and
provide an area at which the fuel may ignite.
Burner Orifi ce
Brass metering device used to feed gas to burner
at a specifi c rate.
Fan Housing
Chamber used for compressing air for effi cient air
movement.
Fan Wheel
Component used in conjunction with the motor and
fan housing to pull the hot air from heater and blow
it into room for heating (also known as a "squirrel
cage").
Gas Hose
Flexible connector used to convey gas from supply
line in building to heater.
Heat Chamber
Metal fi re box within the appliance that provides an
area where burner fl ame mixes with combustion air
thereby providing heat.
High Limit Switch
Safety device wired into the control system which is
used to break an electrical circuit to the gas control
valve in event of overheat situation.
Motor
Electric device used to force preheated air through
the heater and to circulate heat within a certain
area. Converts electrical energy into mechanical
energy.
Pilot Light Orifi ce
A metering device used to supply gas for the dual
purpose of igniting the main burner and heating the
thermocouple.
Pilot Safety Control Valve
A gas control valve which is held open by
electrical power supplied by a pilot generator and
which closes automatically to shut off the fl ow of
gas to the main burner when the pilot fl ame is
extinguished or becomes too small to light the
main burner.
Pilot Shield
A formed sheet metal piece that fi ts around
the pilot assembly to protect the the pilot fl ame
against drafts.
Pilot Tube
Formed copper tube used to convey gas from the
safety control valve to the pilot light orifi ce.
Regulator
The heart of any gas supply installation. Used to
deliver a working pressure to the appliance under
varying conditions in tank pressure.
Thermocouple
A thermoelectric device that converts heat
energy directly into electrical energy. Works in
conjunction with the electromagnet in the gas
control valve thereby providing gas supply for the
pilot light.
Thermostat
Electrical device used as an automatic on/off
switch which will respond to changes in tempera-
ture in a certain area. Can be wired so contacts
in the thermostat open or close on temperature
increase or decrease.
