5. Switch temperature control on.
6. THE INSTALLATION MODE - acts mentioned in the point 6a) and 6b) can
be made only by the installator or the service agent during first firing of the
boiler.
6a) Adjust primary air. Accordingly to observe the length of the flame through the
open cleanout hole. He should reach to about the second shelf from below.
Depending on his length (slowly after ½ the turn {turnover}) to screw tight or
to open the primary air valve to the obtainment of required length of the flame.
6b) Adjust secondary air. Open (closed on the beginning) the valve of secondary
air on 1 turn and then slowly after ¼ turn. It should effect shortening the flame
and the change of his colour on the orange-violet and the lack of smoke from
the chimney.
7. Adjust secondary air supply (the user makes it during the possible change
of the fuel).
First it should be tighten the secondary air valve until feeling slight resistance,
then unscrew it about 1 turn. Then add secondary air gradually by manipulating
(unscrewing) the valve until smoke disappears from the chimney. During heavy
frost water steam can be emitted from the chimney. This is a normal
phenomenon. This operation, i.e. secondary air supply adjustment should be
carried out very slowly, turning the valve by ¼ turn, since you have to allow for the
burning process to stabilize. The adjustment effect should be lack of smoke
coming from the chimney. This process should be carried out with care, since
the correct determines boiler operation and efficiency and thus the heating costs.
Note: – Secondary air supply needs to be adjusted only in two cases:
after the boiler is installed at initial kindling by an authorized installer,
(according to the Installtion Mode)
by the user at fuel type change (e.g. when changing from coal to wood).
In other cases, when one fuel type is used (or rekindling the boiler after it has
gone out), there is no need to carry out any adjustments.
8. Check boiler tightness (fuel loading door, ashpit door and cleanouts) and if smoke
is leaking adjust the hinges.
The bypass device is opened each time before opening any of the door. To do so, the
lever should be set for open position, as it is show on the sticker. After you close the door,
close the by-pass device by putting the lever in closed position.
Fuel should not be thicker than Ø100mm for the 20kW boiler, Ø150mm for the size 30kW to
80kW boilers. It should also not be too small, see the diameters specified in Point 4. - fuel.
During supplement fuel should be arranget on the glowing embers along the boiler
(perpendicular to the burner).Please be careful so as not to cover the burner entirely with a
piece of fuel, especially during kindling.
