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, No. 1 fuel oil or No. 1
diesel fuel only. Kerosene is recommended for use when the
temperature drops below 0°F (-18°C). 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.
