Safety Precautions
■ Do not use this heater for heating human living quarters, garages, workshops, or other such
confined spaces.
■ The flow of combustion and ventilation air must not be obstructed.
■ Proper ventilation air must be provided to support the combustion air requirements of the heater
being used.
■ Lack of proper ventilation air will lead to improper combustion.
■ Improper combustion can lead to carbon monoxide poisoning leading to serious injury or death.
Symptoms of carbon monoxide poisoning can include headaches, dizziness and difficulty in breathing.
■ Proper ventilation air for combustion must be provided in accordance with OSHA 29 CFR 1926.154,

Foreman Ductable Oil Indirect-Fired Heater
Overview
The heater is equipped with a burner assembly. The
assembly includes an electronic igniter, solenoid
valves, and burner head with orifice. When the heater
is turned ON, the igniter will spark, with gas delivered
through the solenoids to the burner orifice. Ignition
will occur.
The burner will heat the heat exchanger. After a
predetermined time frame has passed, a fan controller
will start the main blower motor, and blow cool air over
the heat exchanger. The cool air will be preheated by
passing over the heat exchanger, with warm, dry air
delivered the area to be heated.
Combustion by- products created during the heating
process will be transferred up a vent stack directly to
the outside, thereby providing only clean, dry air to the
heated area.
When the heater is turned OFF, the burner motor is
de-energized turning off the fuel pump. The solenoid
valves will close cutting off fuel to the burner nozzle.
The fan controller will continue to run the main blower
motor for a predetermined period of time to allow the
heat exchanger to cool down. After this time frame
has elapsed, the fan controller will disconnect power
to the fan motor, thereby shutting the fan motor down
completely.
