Heater Component Function

Burner
Cast iron component used to channel gas and
provide an area at which the fuel may ignite.
Burner Orifi ce
Brass metering device used to feed gas to
burner at a specifi c rate.
Burner Tubes
Conducts the heat provided by the ignition of
fuel gas at the burner.
Diff erential Air Pressure Switch
Safety device used to insure that proper positive
and vacuum pressures are within the burner box
before the gas valve is opened.
Direct Spark Ignition Control Module
Electronic printed circuit board which sends
and receives voltages to various controls in an
automatic ignition system. An important safety
feature of the control board is that it will shut
down the entire heater, thereby stopping the
fl ow of fuel gas if burner fl ame goes out.
Fan Housing
Chamber used for delivering air for effi cient air
movement.
Fan Wheel
Component used in conjunction with the motor
and fan housing. It is used to create pressures
within thed burner box used in the distribution of
burner fl ame down the burner tubes.
Gas Control Valve
House an electromagnet which is energized by
voltage and opens to allow passage of gas to
the burner orifi ce.
Gas Hose
Flexible connector used to convey gas from
supply line in building to heater.
Igniter
Ignition device used on automatic direct spark
ignition control systems. Ignites gas by spark.
Owner's Manual • Sentry
Motor
Electric device used to force air through burner box
to create pressure used in the ignition of the heater.
Refl ector
Polished aluminum canopy supported over the
burner tubes. Used to gather and refl ect the radiant
heat provided by the burner tubes back down to
ground level.
Regulator
Mechanical device used in L.P. and natural gas
distribution systems to reduce a higher inlet pres-
sure to a preset lower pressure. The regulator is
responsible to supply a steady outlet pressure to
the heater(s) despite changes in inlet pressure,
heater demand and weather conditions.
Thermostat
A component which responds to a change in
temperature . This component is available for
single stage or two stage heating. The two stage
thermostat incorporates two independent control
circuits which interconnect to the heater's two stage
gas control valve, thereby providing low or high
heat depending on thermostat setpoint.
Transformer
Electrical control used to accept line power supply
primary voltage and reduce it to lower secondary
voltage to operate certain control systems.
