So far as is necessary, the pilot burner and main burner are 
cleaned by after-sales service. 

In a visual check, the flames must be dark blue without any 
upper yellow or orange tips; they must be stable and soot-free 
and adhere firmly to the outlets.
If there is a lack of primary air, the flame has yellow streaks 
and tips; if there is too much primary air, the flame is short, 
transparent and tends to lift off the burner.
When the flame is correctly adjusted, it must not lift off or back-
fire when the burner is cold as well as warm. 
The flame will backfire into the inside of the burner when the 
speed of the gas-air mixture through the burner outlets is too 
low, particularly when the air passages are dirty.
The different ignition processes must also take place without 
any delays. This concerns: ignition, arc-through and. extending 
the flame over the whole burner area.
If the flame fails to meet all the requirements, cleaning or 
maintenance is necessary.

The burners are not accessible to operating personnel. 
Therefore, in the case of a fault, specialist staff must be reque-
sted.
