SAFETY
INFORMATION
WARNINGS
IMPORTANT: Read this Owner’s
Manual carefully and completely
before trying to assemble, operate, or service this heater. Improper use of this heater can
cause serious injury or death from
burns, fire, explosion, electrical
shock, and carbon monoxide
poisoning.
DANGER: Carbon monoxide
poisoning may lead to death!
Carbon Monoxide Poisoning: Early
signs of carbon monoxide poisoning resemble the flu, with headaches, dizziness,
and/or nausea. If you have these signs, the
heater may not be working properly. Get
fresh air at once! Have heater serviced.
Some people are more affected by carbon
monoxide than others. These include pregnant women, persons with heart or lung
disease or anemia, those under the influence
of alcohol, and those at high altitudes.
Make certain you read and understand all
Warnings. Keep this manual for reference.
It is your guide to safe and proper operation
of this heater.
• Use only kerosene or No. 1 fuel oil to
avoid risk of fire or explosion. Never
use gasoline, naphtha, paint thinners,
alcohol, or other highly flammable fuels.
• Fueling
a)Personnel involv ed with fueling shall
be qualified and thoroughly familiar
with the manufacturer's instructions
and applicable federal, state, and local regulations regarding the safe fueling of heating units.
b)Only the type of fuel specified on the
heater's data plate shall be used.
c) All flame, including the pilot light,
if any, shall be extinguished and the
heater allowed to cool, prior to fueling.
d)During fueling, all fuel lines and fuel-
line connections shall be inspected
for leaks. An y leaks shall be repaired
prior to returning the heater to service.
e)At no time shall more than one day's
supply of heater fuel be stored inside
a building in the vicinity of the heater .
Bulk fuel storage shall be outside the
structure.
f) All fuel storage shall be located a
minimum of 762 cm (25 feet) from
heaters, torches, welding equipment,
and similar sources of ignition (exception: the fuel reservoir integral
with the heater unit).
g)Whenever possible, fuel storage shall
be confined to areas where floor penetrations do not permit fuel to drip
onto or be ignited by a fire at lower
elevation.
h)Fuel storage shall be in accordance
with the federal, state, or local authority having jurisdiction.
• Never use heater where gasoline, paint
thinner, or other highly flammable vapors are present.
• Follow all local ordinances and codes
when using heater.
• Heaters used in the vicinity of tarpaulins, canvas, or similar enclosure materials shall be located a safe distance
from such materials. The recommended
minimum safe distance is 305 cm (10
feet). It is further recommended that
these enclosure materials be of a fire
retardant nature. These enclosure materials shall be securely fastened to prevent them from igniting or from upsetting the heater due to wind action.
• Use only in well-vented areas. Before
using heater, provide at least a 2800
square cm (three-square-foot) opening
of fresh, outside air for each 100,000
Btu/Hr of rating.
• Use only in places free of flammable
vapors or high dust content.
• Use only the electrical voltage and frequency specified on model plate.
• Use only a three-prong, grounded extension cord.
• Minimum heater clearances from combustibles:
Outlet: 250 cm (8 Ft.)
Sides, top, and rear: 125 cm (4 Ft.)
• Locate heater on a stable and level sur face if heater is hot or running or a fire
may occur.
• When moving or storing heater, keep
heater in a level position or fuel spillage may occur.

MODEL BY150ECB 150,000 Btu/Hr
PORTABLE FORCED AIR HEATER
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 combustion 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.

WARNING: Use only kerosene
or No. 1 fuel oil to avoid risk of fire
or explosion. Never use gasoline, naphtha, paint thinners, alcohol, 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:
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.
Use a KEROSENE ONLY
VENTILATION
WARNING: Follow the minimum fresh, outside air ventilation requirements. If proper fresh,
outside air ventilation is not provided, carbon monoxide poisoning can occur. Provide proper
fresh, outside air ventilation before running heater.
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:
quires one of the following:
A 150,000 Btu/Hr heater re-
• 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)

PREVENTATIVE MAINTENANCE
STORING,
TRANSPORTING,
OR SHIPPING
Note:
If shipping, transport companies re-
quire fuel tanks to be empty.
1. Drain fuel tank.
Note:
Some models have drain plug on
underside of fuel tank. If so, remove
drain plug to drain all fuel. If heater
does not have drain plug, drain fuel
through fuel cap opening. Be sure all
fuel is removed.
2. Replace drain plug if provided.
3. If any debris is noted in old fuel, add 1
or 2 quarts of clean kerosene to tank,
stir, and drain again. This will prevent
excess debris from clogging filters during future use.
4. Replace fuel cap or drain plug. Prop-
erly dispose of old and dirty fuel. Check
with local automotive service stations
that recycle oil.
5. If storing, store heater in dry place.
Make sure storage place is free of dust
and corrosive fumes.
IMPORTANT:
summer months for use during next heating
season. Using old fuel could damage heater.
Do not store kerosene over
