Operating instructions

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. Refer to Figure 17 and 19.
If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. Refer
to Figure 18 and 20 for incorrect shape of pilot flame.
