PORTABLE FORCED AIR HEATER
MODEL BY150ECB 150,000 Btu/Hr
VENTILATION
WARNING: Follow the mini-
mum fresh, outside air ventila-
tion requirements. If proper fresh,
outside air ventilation is not pro-
vided, carbon monoxide poison-
ing can occur. Provide proper
fresh, outside air ventilation be-
fore running heater.
OPERATION
WARNING: Review and un-
derstand the warnings in the
Safety Information Section, pages
2 and 3. They are needed to safely
operate this heater. Follow all lo-
cal codes when using this heater.
TO START HEATER
1. Follow all ventilation and safety infor-
mation.
2. Fill fuel tank with kerosene or No. 1
fuel oil.
3. Attach fuel cap.
4. Plug power cord of heater into standard
110 volt/50 hertz, grounded (earthed)
outlet. Use an extension cord if needed.
Use only a three-prong, grounded
(earthed) extension cord.
Provide a fresh air opening of at least 2800
square cm (three square feet) for each
100,000 Btu/Hr rating. Provide extra fresh
air if more heaters are being used.
Example:
A 150,000 Btu/Hr heater re-
quires one of the following:
• a two-car garage door raised 15 cm
(six inches)
• a single-car garage door raised
23 cm (nine inches)
• two, 76 cm (thirty-inch) windows
raised 31 cm (twelve inches)
THEORY OF
OPERATION
The Fuel System: The air pump forces
air through the air line. The air is then
pushed through the burner head nozzle.
This air causes fuel to lift from the tank. A
fine mist of fuel is sprayed into the combus-
tion chamber.
The Air System: The motor turns the
fan. The fan pushes air into and around the
combustion chamber. This air is heated
and provides a stream of clean, hot air.
The Ignition System: The electronic
ignitor sends voltage to the spark plug. The
spark plug ignites the fuel and air mixture.
The Flame-Out Control System: This
system causes the heater to shut down if the
flame goes out.

FUELS
WARNING: Use only kerosene
or No. 1 fuel oil to avoid risk of fire
or explosion. Never use gaso-
line, naphtha, paint thinners, al-
cohol, or other highly flammable
fuels.
Do not use heavy fuels such as No. 2 fuel oil
or No. 2 Diesel. Using heavy fuels will
result in:
• clogged fuel filter and nozzle
• carbon build up on spark plug
• the need of non-toxic anti-icer in
fuel during very cold weather
IMPORTANT:
Use a KEROSENE ONLY
storage container. Be sure storage container
is clean. Foreign matter such as rust, dirt, or
water will cause the flame-out control to
shut down heater. Foreign matter may also
require you to clean fuel system often.
