4. BOILER INITIALIZATION TO OPERATION
4.1. BOILER CHECK-UPS BEFORE INITIALIZATION FOR
OPERATION
Before initializing the boiler for operation the service technician must check:
If the installation complies with the project.
Boiler must be filled with water, to be under pressure and to check the entire heating
system for leakages.
Boiler connection to chimney – flue pipe connection lines must be approved by
authorized service technician.
Heating regulators functionality.
Warning
The service technician must train the user how to operate and manage the
boiler and also to fill in the exact start of operation date in the warranty card of
the product.
4.2. FILLING AND DRAINING THE HEATING SYSTEM
The system can be filled or drained with water only if the water corresponds to EN standards
values. The water must be clean, with no color, no suspended particulates, oils and chemically
aggressive and corrosive substances, and also it should not be acid (pH factor must be higher
than 7.0). At first place a comprehensive rinsing of the entire heating system should be
performed.
Warning
Water quantity in the system should not be decreased or drained except in the
cases when the boiler is being repaired or there is risk of freezing. An antifreeze
fluid can be added against freezing, with a volume of 15% from the total liquid
quantity (please see the anti-freezing fluid supplier usage instructions).
Warning
Not fulfilling the above mentioned requirement might result in clogging the heat-
exchanger of the boiler and cracking the cast-iron sections. During the heating
season the water volume in the heating system must be kept constant. If
refilling with water you must be careful to not intake air into the system. The
circulation water should never be drained out from the boiler or the heating
system, except if it is absolutely necessary, for example when doing repairs and
etc. Draining and refilling the system with water increases the risk of corrosion
and boiling stone (scale).
Warning
Filling or topping up water into the heating system must be done only when the
boiler is cold or cooled, in other case the cast-iron sections of the boiler may
crack.
