14.7 Adjustment of the burner
The following circumstances require the adjustment of the burner:
1. The burner should be maintained every six months.
Then the readjustment or the exchange of the electrodes might become necessary.
2. The change of the location of the combustion chamber.
3. The change of the capacity.
4. The change of the type of gas.
The correct adjustment of the burner can only be carried out with a flue gas tester.
Here the following capacity and flue gas values must be kept:
Flue gas loss
: < 9%
Flue gas temperature : < 210°C
O2 : 4 – 6%
CO : < 300ppm
Lambda : 1,25 – 1,5
Heating capacity : 45 - 70 KW (This value can only be calculated under consideration of the temperature of
the water entrance and outlet, as well as the water quantity).
The correct ratio of the combustion air and the gas quantity can be achieved by the correct adjustment of the burner,
with flue gas values within the permitted range.
14.8 The regulation of the gas pressure
is carried out at the pressure controller screw at the gas valve.
Small slotted screw, covered by a plastic flap,
Turn left = minus, Turn right = plus
Basic setting is 8.8mbar, 34 turns entirely (picture1).
The pressure measurement should be tapped from No. 5 (picture 3).
The quantity regulating screw (big rotary switch) is principally regulated to the
maximum and must not be shifted.
14.9 For the regulation of the starting gas the plastic flap E
situated on the quantity regulating screw must be removed,
(picture 2) then turned vertically through 180° and placed onto the
axle, which has become free. The standard adjustment is: + max.
If the burner puffs during the starting period, turn into the direction
of “min” until the burner starts smoothly.

14.10 The quantity of air can be changed at the lateral gate valve of the ventilator housing (page 15, item 31).
Loosen the fastening screw and shift it in the long hole.
to the front: minus,
to the back: plus.
Standard adjustment: see
14.11 The air pressure switch (at switch box bracket)
Adjustment: 2 mbar
