Heater Component Function
BARREL (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
Brass metering device used to feed gas to burner at a
specific rate, with the appropriate pressure.
GAS HOSE
Flexible connector used to convey gas from supply line or
cylinder to heater.
MAIN BURNER VALVE
This valve is located between the pilot safety, gas control
valve and burner. It is manually operated and is used to
open or close the main fuel supply to the burner.
PILOT LIGHT ORIFICE
Small metering device used to supply gas for the dual
purpose of igniting the main burner and heating the
thermocouple. Works directly in conjunction with the
thermocouple
.
PILOT SAFETY GAS CONTROL VALVE
A gas control valve which is held open by electrical power
supplied by a pilot thermocouple and which closes
automatically to shut off the flow of gas to the main burner
when pilot flame is extinguished or becomes too small to
light the main burner.
PILOT LINE
Tubing used to convey gas from gas control valve to pilot
light orifice.
REGULATOR
The heart of any gas supply installation. Used to deliver a
working pressure to the appliance under varying conditions
in tank pressure.
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.
TOP (CASE)
Formed sheet metal case component assembled onto
barrel top used to deflect heat out to surrounding area.
