SAFETY INSTRUCTIONS
This is an oil, direct-fired, forced air heater. It's intended use is primarily temporary heating of buildings under construction, alternation or repair.
!
NOT FOR HOME OR RECREATIONAL VEHICLE USE
WARNING
GENERAL PRECAUTIONS
This is an oil direct-fired forced air heater.
Direct-Fired means that all of the combustion products
enter the heated space. Even though this heater operates
very close to 100 percent combustion efficiency, it still
produces small amounts of carbon monoxide. Carbon
monoxide (called CO) is toxic. We can tolerate small
amounts but not a lot. OSHA says that 50 parts per million
(ppm) in the air we breathe is okay if it does not average more
than that during an 8 hour working period. Regardless, CO
can build up in a heated space and failure to provide
adequate ventilation could result in death. The symptoms
of inadequate ventilation are:
headache
dizziness
burning eyes and nose
nausea
dry mouth or sore throat
So be sure to follow requirements about ventilation in these
operating instructions.
Forced Air means that a blower or fan pushes the air through
the heater. Proper combustion depends upon this air flow;
therefore, the heater must not be revised, modified, or
operated with parts removed or missing. Likewise, safety
systems must not be circumvented or modified in order to
operate the heater.
When the heater is to be operated in the presence of other
people the user is responsible for properly acquainting
those present with the safety precautions and instructions, and of the hazards involved.
SAFETY PRECAUTIONS
1. Check the heater thoroughly for damage. Never operate a damaged heater.
2. Never modify the heater or operate the heater if it has
been modified from its original condition.
3. Use only Kerosene or #1 fuel oil. Never use gasoline,
naphtha, paint thinner, alcohol or other fuels of any
kind.
4. For indoor use only.
5. Use only in well ventilated areas. Provide at least 9 sq.
ft. (K350 - 5 sq. ft.) of opening near the floor and 9 sq. ft.
(K350 - 5 sq. ft.) of opening near the ceiling.
6. Always keep combustibles, like paper and wood at
least 10 ft. from the heater outlet and 4 ft. from the top,
sides and inlet. Locate 10 ft. from canvas or plastic
coverings and secure them to prevent flapping or
movement. This heater produces carbon monoxide,
which is listed by the State of California as a reproductive toxin under proposition 65.
7. Never use in places where exposure to flammable
vapors or high dust content is possible. This includes
gasoline, paint thinners, solvents, coal-dust, sawdust,
etc.
8. Install the heater such that it is not directly exposed to
water spray, rain and/or dripping water or wind.
9. Never use in areas normally for habitation andor where
children may be present.
10. Operate only on a stable, level surface.
11. Do not use with ductwork. Do not restrict inlet orexit.
12. Use only the electrical power specified.
13. Use only a properly grounded 3 wire extension cord.
14. Unplug heater from electrical supply when not in use.
15. Do not move, handle or service while hot or burning.
16. Heater is equipped with a thermostat, and may start at
any time.
17. Use only in accordance with State and Federal
ordinances.

WARNING: FIRE, BURN, INHALATION, AND EXPLOSIOIN HAZARD.
KEEP SOLID COMBUSTIBLES, SUCH AS BUILDING MATERIALS, PAPER
OR CARDBOARD, A SAFE DISTANCE AWAY FROM THE HEATER AS RECOMMENDED BY THE INSTRUCTIONS. NEVER USE THE HEATER IN SPACES
WHICH DO OR MAY CONTAIN VOLATILE OR AIRBORNE COMBUSTIBLES,
OR PRODUCTS SUCH AS GASOLINE, SOLVENTS, PAINT THINNER, DUST
PARTICLES OR UNKNOWN CHEMICALS.
OPERATING INSTRUCTIONS
FUELING
1. Only qualified personnel familiar with these
instructions and applicable local, state, and federal
regulations and codes may fuel this heater.
2. Use only kerosene or #1 fuel oil in this heater.
3. All flames shall be extinguished and the heater
allowed to cool, before fueling.
4. When the heater is removed from service for
fueling, all lines and connections in the fuel system
shall be inspected and any repairs made before
returning heater to operation.
5. The fuel cap gasket and vent hole shall be inspected to insure that they are clear and clean from
contaminates
6. Only the fuel in the internal tank may be stored in
the heated building.
7. In the absents of local regulations and codes bulk
fuel storage must be a minimum of 25 feet from the
heaters, or other sources of ignition.
8. All fuel must pass through the tank inlet screen to
remove foreign material before it enters the tank.
9. CAUTION: Make sure that the fuel used is free of
water.
10. Never operate a heater that does not have a factory
purchased vented fuel cap.
UNPACKING
1. Remove all protective material, which may have
been applied to the heater for shipment.
2. Remove the heater from carton or crate.
3. Check the heater for possible shipping damage. If
any is found immediately notify the dealer from
whom you purchased the heater.
OPERATION
TO FUEL
IMPORTANT: Be sure the fuel storage container is
clean. Foreign matter such as rust, dirt, or water will
cause the flame control to shut down heater. Foreign
matter will also require more frequent cleaning of the
fuel system.
Fill the fuel tank with clean kerosene, No. 1 fuel oil or No. 1
diesel fuel only. Do not use heavy fuels such as No. 2 fuel
oil or No. 2 diesel, because it will build up carbon in
combustion chamber and clog fuel filters. Kerosene is
recommended for use when the temperature drops below
zero degrees fahrenheit (-18
weather, condensation may develop in the tank and it is
recommended that a tablespoon of de-icer be added for
each gallon (4 liters) of fuel in the tank.
When filling the heater use at least 2 gallons (8 liters) of fuel.
Be sure heater is level and do not overfill. Use a funnel or
can with a long fill spout.
WARNING: To avoid fire, wipe up any spilled fuel immediately.
