Heater Component Function
BARREL w/ TOP (CASE)
Upright sheet metal case component. Acts as a chimney to
distribute heat to surrounding area.
BASE
Sheet metal case platform used to support and stabilize
burner and barrel assemblies.
BURNER
Component at which combustion of fuel gases takes place.
BURNER ORIFICE / MANIFOLD
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.
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.
VARIABLE RATE VALVE
A manually adjsuted valve that allows the user to operate
the heater from its lowest to highest heat output, or
anywhere in-between. .
