3.1 GAS BURNER
So far as is necessary, the pilot burner and main burner are
cleaned by after-sales service.
3.2 FLAME
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.
