Monessen Hearth mhsc eyf24 User Manual

24 

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 ther-
mocouple tip for natural. See Figures 30 and 32 for correct pilot flame. 
If the pilot flame does not touch the thermocouple, then the main burner cannot function reliably. See Figures 31 and 33 for 
incorrect shape of pilot flame.
