Heater Component Function
Burner
Allows combustion air to be drawn in with gas
flow for combustion.
Burner Orifice
Metering device used to feed gas to burner at
a specific flow rate.
Canopy
Reflective aluminum heat shield used to reflect
heat down to ground.
Emitter
This is where combustion of gas occurs,
providing radiant heat used in the warming
process.
Gas Control Valve
Component that houses electromagnet which
is energized by voltage. 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
Heavy insulated wire used to supply high
voltage from the ignition control to the igniter
for the purpose of creating spark and ignition
of fuel gas.
L-40 / H-40 Spark Ignition Radiant Brooder
Ignition Control Module
Electronic device which controls the ignition
sequence and operation of the heater.
Manifold
Section of flex tubing used for conveying gas,
connected between the gas control valve and the
burner orifice
On/Off Switch
