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
Metering device used to feed gas to burner at a
specifi c 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 LIGHT ORIFICE
A metering device used to supply gas for the dual
purpose of igniting the main burner and heating the
thermocouple.
PILOT TUBE
Formed copper tube used to convey gas from the
safety control valve to the pilot light orifi ce.
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 supplied by the thermocouple and which
closes automatically to shut off the fl ow of gas to
the main burner when fl ame is extinguished or is
too small to heat the thermocouple.
Vertical Convection Heaters
Owner's Manual • Workman & Norseman
THERMOCOUPLE
A thermoelectric device that converts heat di-
rectly 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.
