4.2 Adjusting combustion air
Adjustment ring positioning
Adjustment ring position has an effect on thif e pressure in the combustion head. Adjust
the pressure by moving the adjustment ring back and forth. This changes the gap
between the adjustment ring and the diffuser disc.
● At low capacity, the adjustment ring is at the front.
● At high capacity, the adjustment ring is at the back.
If...
Then...
Result
The adjustment ring is too
far forwards at full capacity
There is too much pressure
drop in the combustion
head.
● Poor ignition, OR
● Poor combustion due to inadequate amount
of air (high CO content), OR
● Flame tear-off from diffuser disc when
switching to higher capacity
The adjustment ring is too
far towards the back at low
capacity.
There is not enough
pressure drop in the
combustion head.
Poor combustion (O

values too high)
