6. Adjusting operating point P1
Press [-] key.
P
9
is saved.
Burner drives to operating point P
8
.
Check CO content of combustion and if necessary adjust combustion values via
gas butterfly valve setting [G].
Press [-] key.
Next operating point is initiated.
Repeat steps at each operating point until P
1
has been reached.
The speed at operating point P
1
must not be less than 30 %.
Recommended speed: 50 %.
A minimum speed of 50 % should be aimed for in operating point P
1
whilst ob-
serving combustion values and flame stability.
Slowly reduce speed using [L/A] and [ENTER] key, whilst opening air damper
setting alternately using the [L/A] key.
Operating point P
1
must lie within the capacity graph [ch. 3.4.6].
Determine gas throughput and if necessary adjust via gas butterfly valve setting
[G].
Check combustion values
Determine combustion limit and set excess air of approx. 20 … 25 % via air
damper setting [L/A].
7. Adjust ignition load
The ignition speed must not be less than 70 %.
Press [-] key.
Burner drives to operating point P
0
(ignition position).
Check combustion values in operating point P
0
(ignition position).
Set O
2
content of 4 … 5 % above gas butterfly valve setting [G].
Check mixing pressure
The mixing pressure in ignition position must be between 0.5 2.0 mbar.
If necessary, adjust mixing pressure via air damper setting [L/A].
