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 Figure 21 

for correct 

pilot flame. 
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.
