L.B. White I-40 Infraconic Spark Ignition - Manual (Page 23)

Heater Component Function
Air Housing
Allows combustion air to be drawn in to venturi tube with
gas flow for combustion.
Burner Orifice
Metering device used to feed gas to combustion cones at a
specific flow rate.
Canopy
Reflective aluminum heat shield for heater.
Double Combustion Chamber
Made of special alloy steel. This is where combustion of gas
occurs, providing radiant heat used in the warming process.
Consists of small inner cone and large outer cone
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 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.
