Air Proving Switch
Safety device used to insure that the proper air flow
is being achieved before the gas valve is opened.
Burner
Cast iron component used to channel gas and
provide an area at which the fuel may ignite.
Burner Orifice
Brass metering device used to feed gas to burner
at a specific rate.
Fan Housing
Chamber used for compressing air for efficient air
movement.
Fan Wheel
Component used in conjunction with the motor and
fan housing to pull the hot air from heater and blow
it into room for heating (also known as a squirrel
cage).
Flapper (Sail)
A formed piece of stainless steel located in the
blower outlet of the brood heater that pivots up with
an increase in air pressure, thereby engaging air
flow switch. Used on model AW325
Gas Control Valve
A device which consists of a low pressure regulator
and electrical solenoids which are used for the con -
trol of gas flow to the burner assembly. A feature of
the control is a built in gas shut off which is used to
isolate the brood heater from its gas supply when
servicing.
Gas Hose
Flexible connector used to convey gas from supply
line in building to brood heater.
Heat Chamber
Metal fire box within the appliance that provides an
area where burner flame mixes with combustion air
thereby providing heat.
High Limit Switch
Safety device wired into the control system which is
used to break an electrical circuit to the gas control
valve in event of overheat situation.
Brood Heater Component Function
Hot Surface Igniter
Electrical ignition device used on automatic
ignition control systems. Ignites gas by surface
temperature rather than by spark or flame.
Ignition Control Module
Controls the ignition sequence and operation
of the heater as well as monitoring the safety
sevices. A major service feature is the board’s
ability to diagnose component and flame failure
by means of a diagnostic light located within the
module. This light will provide a specific flash
pattern repetitively, depending on the type of
componenet failure that has occurred.
Motor
Electric device used to force preheated air
through the brood heater and to circulate heat
within a certain area. Converts electrical energy
into mechanical energy.
Regulator
The heart of any gas supply installation. Used
to deliver a working pressure to the heater under
varying conditions in tank pressure.
Sensor
Also known as a flame rod or flame probe, this
device works in conjunction with the ignition
module in proving that burner flame has been
established.
Thermostat
Electrical device used as an automatic on/off
switch which will respond to changes in tempera -
ture in a certain area. Can be wired so contacts
in the thermostat open or close on temperature
increase or decrease.
Transformer
Electrical control used to take higher incoming
voltage and reduce it to lower outgoing voltage to
operate certain control systems.
