Filling of the heat system with water:
Water for filling of the boiler and the heat system must be pure and colourless, without suspended
substances, oil and chemically aggressive substances. Its hardness must correspond to
Č
SN 07 7401 and in
case it does not correspond it is necessary the water to be adjusted. Even multiplying heating of the water
with higher hardness does not prevent from excluding of soils on the boiler drum walls. The precipitation of
1 mm of limestone reduces in the given place the heat transfer from metal to water by 10 %.
Heat systems with an open expansive tank allow direct contact of the heat water with atmosphere. In the heat
period the expansive water in the tank absorbs oxygen that increases the rust effects and at the same time a
considerable vaporization of water occurs. Only water adjusted to values according to
Č
SN 07 7401 can be
used for fill – up. The heat system is needed to be rinsed so as all impurities have been washed out.
During heat period it is necessary to keep consistent water volume in the heat system. While filling – up of the
heat system with water it is necessary to prevent the air from leeching onto the system. The water from boiler
and heat system must never be impregnated or taken out for use except for cases necessarily needed such
as repairs, etc. By draining the water and filling with new one the risk of rust and scale creation is increased.
If it is needed to fill water into the heat system we fill it only to a cooled down boiler to prevent
section cracking. After filling of the boiler and heat system checking of tightness of all joints is needed.
The finishing of assembly and the heat test performance must be recorded in the warranty card.

Putting into operation – instructions for a contractual service
organization
Putting the boiler into operation can be performed only by a contractual service organization
authorized for performing of this operation.
6.1
Control operation before starting
Before starting the boiler it is needed to check:
a) filling the heat system with water (thermomanometer check) and system tightness.
b) connection to chimney – this connection can be performed only with consent of a relevant chimney
company according to
Č
SN 73 4201.
6.2
Putting the boiler into operation
1. Performance of fire in the boiler.
2. Setting the boiler on the necessary operating temperature. The recommended temperature of the output
water is 80 °C.
3. Operating of the boiler in the operating condition according to the competent standards.
4. Repeatedly check the boiler tightness.
5. Introduction of the user with servicing.
6. Making a record into the Warranty card.
