3.1. Adjusting the burner

In order to achieve low-emission combustion values, the

burner must be adjusted by measuring the exhaust gas using

suitable measuring instruments.

The measuring hole (Ø 8 mm) is to be located at a distance

of twice the diameter of the exhaust pipe behind the heater

and is to be closed after the measurement.

Caution: The heater and exhaust gas ducts must be

sealed tight.

3.2. Chimney draft

In order to achieve constant combustion chamber pressure,

a draft damper must be installed in the exhaust gas line. The

draft damper must be installed to ensure that the vacuum in

the combustion chamber is not more than 0.1 mbar during

operation.

For overpressure boilers, refer to the boiler operating instruc-

tions to adjust the chimney draft.

3.3. Combustion air

Each burner has been factory-adjusted with a basic air ow

rate, according to the installed nozzle. Depending on the

combustion chamber and the nozzle tolerance, the basic fac-

tory setting leads to an excess of air and must be re-adjusted

in all cases. The required quantity of air is determined from

the soot contents and the CO

measurement. The nal ad-

justment should be performed using the throttle screw.

a. Air flap (see. fig.16)

Turning counter clockwise the air ap set-screw reduces the

air ow from the fan. Therefore, the fan pressure measured

at the measuring tting decreases, and the CO

content in

the exhaust gases increases. Turning the set screw clock-

wise will open the ap and increase the fan pressure, thus

reducing the CO

content in the exhaust gases.

b. Baffle plate (see. fig.16)

• By turning clockwise the bae plate set-screw, the

gap between the burner pipe and bae plate is re-

duced, thus reducing the combustion air volume

while increasing fan pressure and the CO

content of

the exhaust gases.

• For reverse direction of rotation, the gap width and

thus the combustion air volume increases with de-

creasing fan pressure thus decreasing the CO

con-

tent in the exhaust gas.

Pay attention that the fan pressure is kept between 2,0 -

3,5 mbar.

We recommend setting a CO

content of 12 - 13 vol. %.

Fan pressure measurement is to be carried out at the

pressure measurement fitting (1) (see fig. 17).

The soot number may not exceed 0.5 according to the

soot number comparison scale.

3.4. Flame monitoring

The photo-current is to be measured in series with the pho-

tocell (+pole on terminal 12, max. 5 kOhm inner resistance in

the instrument) (see g. 18).

The photo-current must be between 55 μA and 100 μA at

230 V~ while in operation.

Measuring adapter MA 2 (see g. 18) available on request.
