Lighting the Pilot Light
It is always important to read the furnace instruction manual before attempting to light the pilot burner. The basic procedure for lighting a pilot can be done in these four steps:
- Turn the room themostat to its lowest setting to ensure it wont go on
- Shut off the main gas supply to the main burner and the pilot burner
- Allow at least 5 minutes to go by so the unburned gas can vent
- Light the pilot burner in accordance with the furnace instructions
Venting the unburned gas is the most important step here. This is especially true for LP gas because it is heavier than air and will not vent upward on its own. Every precaution should be taken to make sure the appliance is properly venting the unburned gas. Appliance and pilot burner instruction are very detailed for their lighting process of their equipment. The development of various types of combination gas controls has simplified the lighting procedure and increased the safety factor.
