EYF Series Unvented Gas Log Set | FLAME APPEARANCE |
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 Figures 29 & 30 for correct pilot flame.
If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. Refer to Figures 29 & 30 for incorrect shape of pilot flame.
