Premier Ductable Heaters
Owner’s Manual • Premier 80-170
39
Air Proving Switch
Safety device used to insure that the proper air
fl
ow
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 Ori
fi
ce
Brass metering device used to feed gas to burner
at a speci
fi
c rate.
Direct Spark Ignition Control Module
Electronic printed circuit board which sends and
receives voltages to various controls in an auto-
matic 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 ef
fi
cient 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).
Gas Control Valve
Electrical device consisting of a low pressure regu-
lator and electrical solenoids used for the control
of gas
fl
ow to the burner assembly. A feature of the
control valve is a built-in gas shut off which may be
used to isolate the heater from its gas supply when
servicing.
Gas Hose
Flexible connector used to convey gas from supply
line in building to heater.
Gas Selector Valve
Allows easy gas conversion depending on gas
being supplied at job site. Eliminates the need for
changeout of the burner ori
fi
ce . (Available on DF
heaters only.)
Heat Chamber
Metal
fi
re box within the appliance that provides an
area where burner
fl
ame mixes with combustion
air, thereby providing heat.
Heater Component Function
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. (All
Premier heaters have two limit switches.)
Igniter
Ignition device used on automatic direct spark
ignition control systems. Ignites gas by spark.
Motor
Electric device used to force preheated air
through the heater and to circulate heat within
a certain area. Converts electrical energy into
mechanical energy.
Regulator
Mechanical device used in gas distribution sys-
tems to reduce a higher inlet pressure 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.
Selector Switch
Electrical device which is used to allow the end
user to use the heater in either a heating or venti-
lation application.
Status Light
A green light emitting diode (L.E.D.) wired into
the electrical circuit. Provides an easily recogniz-
able indication of heater operation.
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 accept line power
supply primary voltage and reduce it to lower
secondary voltage to operate certain control
systems.
