Foreman Ductable Dual Fuel Indirect-Fired Heater

Heater Component Function

Air pressure switch
Safety device used to ensure that proper air pressure
(positive and vacuum) is created within the burner before
the gas solenoid valves are opened.
Bearings
Components used to support the shaft and reduce friction
between the pulleys and motor.
Belt
Friction drive component used for transmission of power
from motor to fan shaft. Used in conjunction with motor
and fan pulleys.
Capacitor
A storage device for power that assists starting and run-
ning the motor during a call for heat.
Fan
Component used in conjunction with the motor and fan
housing to move air.
Flame sensor
Used with the ignition control, it proves that burner fl ame is
established and keeps the burner in operation as long as
there is a call for heat.
Fuse
Safety device used to protect used to protect against an
over amperage condition, resulting from a direct short or
an electrical overload.
Gas Selector Valve
Allows easy gas conversion depending on gas being
supplied at job site. It eliminates the need for change-out
of the burner orifi ce.
Gas Hose
Flexible connector used to convey gas from the gas sup-
ply to the heater.
Heat exchanger
A sealed chamber used to transfer heat from the burner on
one side to cool air on the other side, thereby preheating
the cooler air.
High Limit Switch
Safety device wired into the control system which is used
to break an electrical circuit to the to the burner in the
event of overheat situation.
High voltage ignition cable
A cable connected between the ignition transformer and
igniter that provide high voltage to create spark.
Owner's Manual • Foreman
Igniter
Ignition device used on automatic direct spark igni-
tion control systems. Ignites gas by spark.
Burner controller
Electronic circuit board that operates the burner. It
will safely shut the heater down if burner fl ame goes
out.
Ignition Transformer
An electrical component used to take incoming
line voltage and increase it to create high voltage
that causes spark between the ignitor and earth
grounded surface.
Motor
Electric device used for air movement. Converts
electrical energy into mechanical energy.
Orifi ce
Metering device used to feed gas to burner at a
specifi c rate.
Pulleys
Grooved friction drive components responsible for
transmission of power from motor to fan shaft. Used
in conjunction with V-Belt.
Regulator
Device used in L.P. and natural gas distribution
systems 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 ventilation
application.
Solenoid Valve
Houses an electromagnet that when energized,
opens and allows gas passage to the burner
Status lights
Used to identify if the heater is receiving its power
supply and if certain electrical safety components are
functioning properly.
Thermostat
Electrical device used as an automatic "on/off" switch
which will respond to changes in temperature.
