Spark Ignition Heaters
Component Function
Air Housing
Secures safety control valve to venturi tube.
Also allows combustion air to be drawn in to
injector tube with gas flow for combustion.
Burner Orifices
Metering devices used to feed gas to combus-
tion cones at a specific flow rate.
Canopy
Reflective aluminum heat shield for heater.
Double Combustion Chamber
Made of stainless steel. This is where combus-
tion of gas occurs, providing radiant heat used
in the warming process.
Gas Hose
Flexible connector used to convey gas from
gas supply line to inlet of heater.
Gas Control Valve
Component that houses electromagnet which
is energized by voltage and therefore opens
or closes to supply or shut off the flow of gas
to the burner.
Gas Hose
Flexible connector used to convey gas from
gas supply line to inlet of heater.

Igniter/Sensor
Electrical ignition device used on automatic
ignition control systems. Ignites gas by spark.
The igniter also serves as a flame sensor on
this heater to prove flame after ignition.
Ignition Cable
Receives high voltage from the ignition control
and transmits if to the igniter for creation of
spark. The cable is also used to support flame
sensor.
Ignition Control Module
Electronic device which controls the ignition
sequence and operation of the heater.
On/Off Switch
Simple electrical device used to connect or
disconnect incoming voltage at the ignition
control box on the heater.
Venturi Tube
Tubular steel neck connecting the gas control
valve and burner orifices to the combustion
cones. Gas is fed to the combustion cones
through the injector tube.
