Oval 80 and Sentinel Radiant Tube Brood Heaters
Owner’s Manual • Oval 80 and Sentinel
31
Motor
Electric device used to force air through burner box
to create pressure used in the ignition of the brood
heater.
Refl ector
Polished aluminum canopy supported over the
burner tubes. Used to gather and re
fl
ect the radiant
heat provided by the burner tubes back down to
ground level.
Regulator
Mechanical device used in L.P. and natural gas dis-
tribution systems to reduce a higher inlet pressure
to a preset lower pressure. The regulator is respon-
sible to supply a steady outlet pressure to the brood
heater(s) despite changes in inlet pressure, heater
demand and weather conditions.
Thermostat
A component which responds to a change in
temperature.
Transformer
Electrical control used to accept line power supply
primary voltage and reduce it to lower secondary
voltage to operate certain control systems.
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 speci
fi
c rate.
Burner Tubes
Conducts the heat provided by the ignition of
fuel gas at the burner.
Differential 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 brood heater, thereby stopping
the
fl
ow of fuel gas if burner
fl
ame goes out.
Fan Housing
Chamber used for delivering air for ef
fi
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
Electrical device consisting of a low pressure
regulator and electrical solenoids used for the
control of gas
fl
ow to the burner assembly.
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.
