Putting the boiler into service
Checking the boiler before turning it on
Before putting the boiler into operation, the
service technician must check:
Whether the installation conforms to the
design.
Whether the boiler has been filled in and is
under pressure (on the thermometer), and
whether there are any leakage in the heating
system;
Connection to the chimney - connection must
be approved by an authorised chimney sweep
(chimney inspection);
Functioning of the heating controls.
Please note
The service technician must show the user
how to control the boiler and enter the date
when the boiler was put into service into the
warranty certificate.
Filling up and draining the heating system
The system can only been filled up or topped
up with water which meets the parameters
specified by EN standards. The water must be
clear, colourless, free of suspended particles,
oil and chemically corrosive substances, and
must not be acidic (
P
H factor must be
greater than 7.2 ). First of all, the heating
system must be thoroughly flushed and all dirt
washed out.
Please note
Water in system must not be reduced or put
out unless the boiler is in service or under
freezing danger. Against freezing anti-freeze
liquid can be added in to system water at the
rate of % 15.
Please note
The failure to meet this requirement may lead
to the heat exchanger getting clogged up, and
the steel block may crack as a result.
