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.
CHECK 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 21 for correct
pilot flame.
If the pilot flame does not touch the thermocouple, then
the main burner cannot function reliably. Refer to Figure
22 for incorrect shape of pilot flame.
