WARNING: Never leave the heater unattended while operating.
Disconnect the heater from its power source when not in use.
PREPARATION FOR STARTING YOUR HEATER
Visually inspect the heater for signs of damage. If any damage is found do not operate the heater. Contact PowerFast Product
Group for assistance at [phone]. Read, understand, and follow all of the instrucons before assembling, operang or
servicing this heater.
FUELING THE HEATER
Make certain the heater is level. Remove the fuel cap and ll the fuel tank with clean kerosene for opmal performance of this
heater. This heater has been factory approved for use with JP8/Jet A, #1 and #2 Fuel Oil, #1 and #2 Diesel. Diesel does not burn
as clean as 1-K kerosene, and care should be taken to provide more fresh air venlaon to accommodate any added contaminants
that may be produced during operaon of the heater. In extreme cold temperatures, it is recommended a fuel stabilizer formulated
to remove condensaon and to prevent the fuel from gelling be added to the fuel tank. Do not overll the fuel tank. Replace the
fuel cap aer lling the fuel tank.
• NEVER store kerosene in the living space. Kerosene should be stored in a well venlated area outside the living area.
• NEVER store kerosene in direct sunlight or near a source of heat.
• NEVER use kerosene that has been stored from one season to the next. Kerosene deteriorates over me. OLD KEROSENE
WILL NOT BURN PROPERLY IN THIS HEATER.
• Use 1-K kerosene in this heater. #1 fuel is a suitable substute.
WARNING:
• DO NOT START HEATER WHEN THE HEATER IS HOT.
• DO NOT START HEATER WHEN EXCESS FUEL HAS
ACCUMULATED IN THE CHAMBER.
• NOT FOR USE WITH AN EXTERNAL FUEL TANK.
• NEVER FILL THE FUEL TANK IN LIVING SPACE
• DO NOT USE GASOLINE OR CRANKCASE DRAINING,
NAPHTHA OR VOLATILE FUELS.
• ALWAYS FILL THE FUEL TANK OUTDOORS AWAY FROM
LIVING AREAS.
NOTICE:
The rst me you light the heater, it should be done OUTDOORS. This allows the oils, and other lubricants used in the
manufacturing process to be burned off outside.
WARNING: RISK OF CARBON MONOXIDE POISONING
• Use this heater only in well venlated areas! Provide at
least a three square feet (2,800 sq cm) opening of outside
air for every 45,000 BTU/Hr. of heater rang.
• Early signs of carbon monoxide poisoning resemble flu-like
symptoms such as headaches, dizziness, and/or nausea. If
you have these symptoms, your heater may not be working
properly.
• Get fresh air at once! Have the heater serviced.
• Some people are more affected by carbon monoxide than
others. These include pregnant women, those with heart
or lung problems, anemia, those under the influence of
alcohol, or at high altudes.
• Never use this heater in living or sleeping areas.
• People with breathing problems should consult a physician
before using the heater.
CONNECTING TO THE POWER SOURCE
Aer lling the fuel tank with approved fuel, connect the plug to a 3-prong, grounded extension cord adequately rated for this
applicaon.
Extension Cord Wire Size Requirements:
• 6 to 10 feet (1.8 to 3 meters) long, use 18 AWG conductor.
• 11 to 100 feet (3.4 to 30.53 meters) long, use 16 AWG conductor.
• 101 to 200 feet (30.8 to 61 meters) long, use 14 AWG conductor.
