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.
Direct Spark Ignition Control Module
Electronic printed circuit board which sends and receives
voltages to various controls in an automatic ignition system.
An important safety feature of the control board is that it will
shut down the entire heater, thereby stopping the flow of
fuel gas if burner flame goes out.
Fan Housing
Chamber used for delivering 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 Control Valve
Electrical device consisting of a low pressure regulator and
electrical solenoids used for the control of gas flow to the
burner assembly. A feature of the control valve is a built-in
gas shut off which may be used to isolate the heater from
its gas supply when servicing.
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.
Igniter
Ignition device used on automatic direct spark ignition
control systems. Ignites gas by spark.
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.
Regulator
Mechanical device used in gas distribution systems to
reduce a higher inlet pressure to a preset lower pressure.
The regulator is responsible to supply a steady outlet
pressure to the heater(s) despite changes in inlet pressure,
heater demand and weather conditions.
Selector Switch
Electrical device which is used to allow the end user to use
the heater in either a heating or ventilation application.
Status Light
A green light emitting diode (L.E.D.) wired into the electrical
circuit. Provides an easily recognizable indication of heater
operation.
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.
Transformer
Electrical control used to accept line power supply primary
voltage and reduce it to lower secondary voltage to operate
certain control systems.
