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.

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.

Correct log flame appearance

Burner will have a random pattern of yellow flames. Refer to Figures 23 and 24. There should be glowing embers in front of burner.

NOTE: The front flames and embers will be an opaque orange color during the burn off time.
