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 flame must always be present when the heater is in operation. It should just touch the top of the
thermocouple tip for natural. Refer to Figure 23 and 25 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. Refer to Figure 24 and 26
for incorrect shape of pilot flame.
