PREPARING FOR OPERATION
1. Check the heater for possible shipping damage. If any is
found, immediately contact the manufacturer at
800-251-0001.
2. Follow all of the "Precautions".
3. Fill the fuel tank with clean kerosene, JP8 Jet Fuel, #1/#2
Diesel or #1/#2 Fuel Oil. 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 are 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.
