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 as this fuel will
damage your heater’s seals and lter.
- 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 kerosene in the living space.
Kerosene should be stored in a well ventilated 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 time. OLD Kerosene WILL NOT BURN
PROPERLY IN THIS HEATER.
NOTE: Kerosene should only be stored in a blue
container that is clearly marked “Kerosene.”
Never store kerosene 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 cm
2
for each 29 kW of
heater output. Provide a larger opening if more
heaters are being used.
Minimum Ventilation Opening Needed
