FLAME APPEARANCE
Flames from the pilot and 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. Figure 31 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. Refer to Figure 32 for incorrect shape of pilot flame.
