Starting the Heater: (Ignition)
1. Fill the tank with kerosene or other approved
fuel until needle on fuel gauge points to "F".
2. Replace fuel cap and tighten firmly.
3. Connect the heater to power source, either
approved battery or a three prong (grounded)
power source. You must use a three prong
(grounded) extension cord that is at least 6 feet
long and is a minimum of 14 AWG rating.
4. Turn thermostat control knob to desired
temperature setting.
5. Move the power switch to the "On" position. The
power indicator light will illuminate and heater
will ignite.
NOTE: On first ignition or after refueling, you may hear a
grinding sound just before ignition. This is the fuel pump
removing the air from the fuel line. Your heater will start
up within seconds. If it does not start repeat start-up pro-
cedures with fuel gauge reading at least 1/2 tank.
NOTE: Smoking may occur on first ignition.
NOTE: The electrical components of these heaters are
protected by a fuse mounted in the PC board. If the
heater fails to ignite, check this fuse first and replace if
necessary. Also check the power source to be sure the
proper voltage is being provided to the heater.
TIP: If the heater does not ignite; move
switch to "Off" position, check steps 1-3
above and then move switch to "On" position.
