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 PILOT FLAME
The pilot flame 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 19 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the burners cannot function reliably. See Figure 20 for incorrect
