Basic setting of secondary air

Setting of the

rear

secondary air: DC105S

fully closed (0 mm) + 8 mm

Setting of the

rear

secondary air: DC150S

fully closed (0 mm) + 15 mm

Setting of the

front

additional

secondary air:

(DC105S and DC150S)

We regulate by turning the regulating (adjusting) screw. By

turning the screw by 1 revolution anticlockwise we open the

secondary air by 1,75 mm (1 revolution = 1,75 mm).

The manufacturer set the regulation to approx. 2 mm open-

ing (up to the stop + 1 turn anticlockwise).

INFO -

Adjustments to settings should be done on the basis of the waste gas analyzer and

maximum temperature; which must not exceed 320 °C at the outlet to chimney, at stabilised

nominal output /with closed ignition valve/. The boiler is set to optimal operating parame-

ters by the manufacturer.

25. Fuel Refill

Before fuelling, open the ignition valve /13/ with the pulling rod /17/. Wait for approximately

10 seconds and slowly open the loading door /2/ so that any accumulated gases are first draw off the

loading (upper) chamber into the flue-gas duct by exhaust fans instead of escaping into the boiler

room. Place a broad log over glowing charcoals. Be careful not to pack the fuel down too much above

the gasification nozzle. This may extinguish the flame. When loading fuel fill the hopper up com-

pletely. In order to prevent excessive smoke formation, load new batch of fuel only after the previous

fuel has combusted to at least one third of the loading volume.

ATTENTION - during operation the ignition valve pulling rod /17/ must be inserted.

INFO - In case of loading fuel and not running exhaust fans the fans automatically

starts by opening the door.
