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.

See Figures 23 and 25

for correct pilot flame.

If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably.

See Figures 24 and

26

for incorrect shape of pilot flame.
