6.2. Verification activities before start-up
The following checks must be performed before start-up:
a) Filling the heating system with water
The water used for filling boiler and heating systems must be clear and colourless, without suspended
solids, oil and aggressive chemicals. Its hardness must comply with
Č
SN 07 7401: 1992 and it is
essential that in case the water hardness does not comply, it must be treated. Even multiple heating of
water with a higher hardness does not stop salt build-up on the walls of the exchanger. 1 mm of calcite
reduces the heat transfer from metal to water at the given point by approximately 10%.
Heating systems with an open expansion tank allow direct contact between the heating water and the
atmosphere. During the heating season the water expanding in the tank absorbs oxygen which increases
corrosion and at the same results in significant water evaporation. Refilling can only be performed with
water treated according to
Č
SN 07 7401:1992. The heating system must be thoroughly flushed in order to
wash out all impurities.
During the heating season it is necessary to maintain a constant volume of water in the heating system.
When refilling the heating system with water no air must be sucked into the system. The boiler and
heating system water must never be discharged or taken for use except in emergencies like repairs etc.
Water discharge and filling with new water increases the danger of corrosion and scaling.
If it is necessary to refill the heating system with water only do this when the boiler is cold to
prevent damage to the steel heat exchanger.
b) Heating system tightness
c) Connection of emergency fire-fighting equipment to the water distribution system
d) Connection to the chimney - must be approved by a chimney sweeping company
e) Ceramic reflector of BENEKOV S16 and S26 boilers (fig. no. 24, pos. 7) fitted into the combustion
chamber of the burner, i.e. laid on the obliquely welded beams (8) in the boiler body and attached to the
back wall of the combustion chamber.
Ceramic reflector of BENEKOV S51 boiler (fig. no. 25, pos. 7) fitted into the combustion chamber of the
burner, i.e. laid on the horizontally welded beams (8) in the boiler body and attached to the back wall of
the combustion chamber.
f) Electric connection
The assembly completion and heating test must be recorded in the "Guarantee certificate".
6.3. Putting into operation
1. Fire the boiler.
2. Bring the boiler to operating temperature. The recommended operating temperature of the output
heating water is 65 to 80 °C.
3. Check the boiler tightness again.
4. Carry out the heating test according to relevant standards (see the Guarantee certificate)
5. Acquaint the user with the boiler operation - see chapter 7.
6. Make a record in the Guarantee certificate.
