FLAME APPEARANCE

Flames from the pilot, front and rear burner should be visually checked as soon as the heater is installed.
In addition, periodically check the flames visually during operation.
CHECKING THE PILOT FLAME
The pilot fl ame must always be present when the heater is in operation. It should just touch the top of the ther-
mocouple tip for natural. See Figure 36 and 40 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. See Figure 39 and 4` for
incorrect shape of pilot flame.
