Heater Component Function
Burner Orifice
Metering device used to feed gas to combustion cones at a
specific flow rate.
Canopy
Reflective aluminum heat shield for heater.
Combustion Cones
Made of special alloy steel. This is where combustion 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.
Manual Shut Off Valve
Shuts off gas flow to the heater if maintenance or service
are required, or if an emergency situation occurs. When the
handle on the manual valve is turned parallel to gas flow,
the valve is completely open delivering full gas supply to the
appliance. Turning handle perpendicular (90°) to gas flow
shuts off gas flow.
Pilot Safety Control Valve
Safety shut off device used to feed fuel gas to the heater
combustion cones for heating. Will shut off flow of gas
completely if gas flame is extinguished.
Thermocouple
Safety device that will continue to hold open electromagnet
in safety gas control valve when heat is applied to
thermocouple tip. It will also stop gas flow if inner
combustion flame is out.
Thermostatic Head and Sensor Assembly
Non-electric component of zone control panel. Used to
modulate the heater from low to high heat and to maintain a
specific temperature.
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 venturi tube.
