Heater Component Function

Air Proving Switch 

Safety device used to insure that the proper air flow 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 Orifice

Brass metering device used to feed gas to burner at a

specific rate.

Fan Housing

Chamber used for compressing air for efficient 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 “fire box” within the appliance that provides an area

where burner flame 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 Orifice

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 flow of gas to the main burner when the pilot

flame is extinguished or becomes too small to light the main

burner.

Pilot Shield

A formed sheet metal piece that fits around the pilot

assembly to protect the the pilot flame against drafts.

Pilot Tube

Formed copper tube used to convey gas from the safety

control valve to the pilot light orifice.  The tube is internally

“tinned” when natural gas is used to resist the effects of

sulphur in the fuel.

Regulator

The heart of any gas supply installation.  Used to deliver a

working pressure to the appliance under varying conditions

in tank pressure.

Sail (Flapper)

A formed piece of stainless steel located in the blower outlet

of the heater that pivots up with an increase in air pressure,

thereby engaging air flow switch.  

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 temperature in a certain

area.  Can be wired so contacts in the thermostat open or

close on temperature increase or decrease.
