chemically aggressive acids, under effect of which boiler service life can be
reduced significantly. In order to ensure whether the boiler is tight, burn it
intensely for 1-2 hrs, then observe for growing condensate volume. If
condensate does not grow in volume, boiler is tight.
In order to ensure whether the boiler is tight, burn it intensely for several
hours, then stop burning and observe for growing condensate volume. If
condensate does not grow in volume, boiler is tight
.
Attention!
If boiler is operated incorrectly, fuel is unsuitable, low chimney
draught, valves installed in the boiler can get stuck, so during the heating
season move the valves: open and close several times all the valves
installed in the boiler.
7.3. Draught regulator adjustment
Attention!
Draught regulator (28) (see fig. 1) is supplied screwed into the
boiler but unsealed, it has to be sealed
(
see par. 6.5
).
After boiler reaches desirable temperature (70÷90°C), comparing with the
readings of thermal pressure gauge (
30
) installed in the boiler, set regulator at
similar temperature.
Note.
Regulator’s dial misalignment with readings of thermal pressure gauge
is possible.
Reduce chain so that primary air supply valves (
23
) were closed or the gap
was no more than 2 mm. Set desired temperature by turning regulator knob to
relevant position. If exhauster (
11
) is used, set its temperature in the same way
as for draught regulator (
28
).
7.4. Chimney exhauster control
More about exhauster
DM-01
control read in „
Exhauster control manual
“.
7.5. Boiler extinguishing
During usual operation, boiler is self-extinguishing when fuel charge
completely burns out. If boiler has to be extinguished in the forced way,
firstly, remove fuel from hearth. Throw burning fuel into a vessel with water –
this will reduce smoke in the premises. During forced extinguishing, open
roods or windows to assure good ventilation of the premises.
Attention!
It is prohibited to pour water onto burning fuel in the hearth.

•
Acids of the condensate and heat-cold erosion can disintegrate chimney in a
couple of years;
•
Uncontrolled sooth in the chimney in some time can get on fire and, if
chimney is in bad order or roofing is easily combustible, cause fire.
We recommend:
•
To install stainless steel insert in the chimney. Orderly installed insert protects
chimney from condensate effect and improves draught;
•
Insert has not to reduce chimney hole cross-section significantly;
•
Parts of the insert have to be sealed together (not by soldering);
