Operation
Fueling The Heater:
Parafn
For optimal performance of this heater, it is
strongly suggested that Parafn be used.
Parafn has been rened to virtually eliminate
contaminants, such as sulfur, which can cause
a rotten egg odor during the operation of the
heater. Using diesel fuel can cause excess soot
production. Do not use Bio-Diesel or Farm “red”
diesel as this fuel will damage your heater’s seals
and lter.
Factory tested for use with parafn, no. 1 &
no.2 diesel, JP8/Jet A Fuel, no. 1 and no. 2
fuel oil.
- NEVER use fuel such as, benzene, alcohol, white
gas, camp stove fuel, paint thinners, or other oil
compounds in this heater. THESE ARE VOLATILE
FUELS THAT CAN CAUSE A FIRE OR
EXPLOSION.
- NEVER store Paraffin in the living space. Paraffin
should be stored in a well ventilated area outside
the living area.
- NEVER store Paraffin in direct sunlight or near a
source of heat.
- NEVER use Paraffin that has been stored from one
season to the next. Paraffin deteriorates over time.
OLD Paraffin WILL NOT BURN PROPERLY IN
THIS HEATER.
NOTE: Parafn should only be stored in
a blue container that is clearly marked
“Parafn.” Never store Parafn in a red
container. Red is associated with gasoline.
Ventilation:
- Risk of indoor air pollution and Carbon
Monoxide Poisoning. Use heater only in well
ventilated areas.
- Refer to Safety Information on pages 1-2 for
information about Carbon Monoxide Poisoning.
- ALWAYS provide a fresh air opening in the heated
space of at least 2,800 square centimeters
(3 sq. ft) for each 29 kW (100,000 Btu / Hr.) of
heater output. Provide a larger opening if more
heaters are being used.
