4. Commissioning
Putting the boiler into operation can be performed only by professional installation companies
authorized to carry out this work.
.
4.1 Control activities before starting
Before putting the boiler into operation it is necessary to check:
1.
Filling the heating system with water (inspection of the thermomanometer) and the tightness of the
system. Heating system must be thoroughly rinsed out in order to wash out all impurities that might be
deposited in piping or radiators and consequently would cause damage to the pump. Water for filling the
boiler and heating system must be clear and colourless, without any suspended substances, oil and
chemically aggressive substances. Its hardness must comply with
Č
SN 07 7401 and in case of
dissatisfactory hardness the water must be treated. Even a repeated heating of water with a higher
hardness does not prevent the salts from segregation on the walls of boiler drum. By precipitation of 1
mm calcite at a given point the heat transfer from metal to water is reduced by 10 %.The heating
systems with an open expansion tank allow a direct contact between the heating water and the
atmosphere. During the heating season the expanding water in the reservoir absorbs the oxygen which
increases the corrosive effects and at the same time lot of water evaporates. Only the water treated to
the values according to
Č SN 07 7401 can be used for refilling.
During the heating season it is necessary to maintain a constant water volume in the heating system.
When refilling the water in the heating system it is necessary to ensure that no air is sucked into the
system. The water from boiler and the heating system must never be discharged or be used except the
emergency cases like the repairs, etc. By emptying the boiler and filling it with new water the danger of
corrosion and the scaling is increased.
If it is necessary to refill water in the heating system, we only do it when the boiler has cooled down so
that the heat exchanger cannot be damaged.
2. Connection to the chimney - this connection can be made only with the consent of the competent
chimney company (revision of chimney).
3. Connection of the two-way safety valve DBV 1 – 02.
4. Connection to electrical network.
5. Tightness of the stoking door and ash pan doors:
Approximately in the middle of sealing cord there must be about 2 mm groove (see Fig. no. 12-12, 13)
uniformly along the whole circumference as the imprint of the sealing surface. If there is no groove in
the sealing cord the door should be adjusted. The untightness can be removed both on the side of
handle and on the side of hinges. On the side of hinges there must be dismounted the side shell and the
eyes of hinges must be adjusted by means of nuts M 16.
Tightening of the handle (see Fig.no. 12) is carried out as follows:
•
loosen the screws of handle (9) and remove the handle (3)
•
loosen the locking nuts (5)
•
loosen the set screw (6) as required
•
put on the handle (3) and secure with locking screws (9)
•
close the door
•
tighten the set screw (6)
•
loosen the locking screws (9)
•
remove the handle (3) and tighten the nuts (5)
•
put on the handle (3) and secure with screws (9).
Slumping or otherwise misaligned door can be centered by loosening the door hinges:
•
in case of stoking door by releasing three bolts M 10 the inside the door at hinges.
•
in case of ash pan door by releasing the hinges after dismantling the front shell.
