Heater Component Function
BURNER
Component at which combustion of fuel gases takes place.
BURNER ORIFICE
Metering device used to feed gas to burner at a specific
rate, with the appropriate pressure.
ELECTRODE
Ignites gas by spark. Receives spark voltage from piezo
igniter.
GAS HOSE
Flexible connector used to convey gas from supply line or
cylinder to heater.
PIEZO IGNITER
Generates ignition voltage when igniter button is pushed.
This voltage is sent to electrode to provide spark.
PILOT ORIFICE
Metering device used to supply gas for the dual purpose of
igniting the main burner and heating the thermocouple.
REGULATOR
The heart of any gas supply installation. Used to deliver a
working pressure to the appliance under varying conditions
in tank pressure.
SAFETY CONTROL VALVE
A gas control valve which is held open by electrical power
s u p p l i e d by t h e t h e r m o c o u p l e a n d w h i c h c l o s e s
automatically to shut off the flow of gas to the main burner
when flame is extinguished or is too small to heat the
thermocouple.
THERMOCOUPLE
A thermoelectric device that converts heat directly into
electrical energy. Works in conjunction with electromagnet
in gas control valve thereby assisting in maintaining gas
supply for the pilot light.
TIP SWITCH
A normally closed switch that opens the connection
between the thermocouple and safety control if the heater
is tipped over, thereby shutting the heater down.
