Following is an outline of the Radiant Heater basic operation process:

RADIANT HEATER OPERATION

Keep unit on a level, non-combustible surface at all times. If the unit is on sitting on a 25° angle or
more the tip switch will prevent the heater from starting.
1. Fill tank with Diesel or #2 Fuel Oil.
2. Plug into a grounded outlet or extension cord.
3. Switch to high fire.
4. Turn power switch ON.
5. The blower will come on and run for 15 seconds prior to lighting (pre-purge).
6. Once the heater is running you will have a green light for power, and an amber light for high fire.
When the unit is switched to low fire the amber light is off.
7. When shutting down the heater turn power switch to off. Allow the burner to complete the post-
purge cycle 300 seconds before disconnecting power. Failure to complete the post purge cycle may
result in excessive heat damaging the unit, as well as a longer pre-purge cycle on the next start.
