PREPARING FOR OPERATION
1. Check the heater for possible shipping damage. If any is
found, immediately notify the factory.
2. Follow all of the "Precautions".
3. Fill the fuel tank with clean kerosene. In extremely cold
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.
IMPORTANT: Before filling fuel tank the first time or after
extended storage periods, drain the fuel tank of any moisture
or condensation.
4. Locate heater at a safe distance from combustible materials.
ModelS 50K & 75KT is not suitable for use on wood floors or
other combustible materials. When used, the heater should
rest on suitable insulating material at least 1 inch thick and
extending 3 ft. or more beyond the heater in all directions.
