NOTE: It is recommended to connect the boiler to heating system provided
with three- or four-pass valve. The main advantage of such connection is boiler
protection function against low temperature corrosion, preventing it from
premature wear.
If not satisfactory to comply with manufacturer’s recommendations in reference
to maintaining given heating water temperature ranges occurs (table TECHNICAL
– EXPLOATATION PARAMETERS p. 11-12, point 12, 13 it concerns in particular
long-lasting return water temperature below 55°C), then the boiler should be
connected to the heating installation equipped with three- or four-pass valve protecting
it against low temperature corrosion.
6.5 . CONNECTING BOILER TO ELECTRICAL INSTALLATION
Boiler room should be equipped with electrical installation 230V/50Hz should
be according to detailed regulations being in force in the country of destination.
Electric socked should be earthed. Grounding functionality should be checked.
Cable extensions are forbidden. Faulty installation may cause the controller to be
destroyed or be unsafe for the user. Controller and other cooperating devices are
powered with 230 V, therefore all connections shell be made by qualified
personnel (certified electrician).
NOTE: Electrical cables of powered devices should be placed away from
boiler’s parts, which tend to be hot during exploitation of boiler ( cover
of the upper washout hole, smoke conduit, door).
7.1. FILING WITH WATER
Boiler and the entire installation water filling is to be performed using blowdown
connection.
This activity should be performed slowly allowing the air residing in the
installation to be removed. It is accomplished when water is going out of
overflow pipe. When filling the heating system installation with water it is
recommended to loose screw connection at the place of boiler – installation
assembly (on the hot water connector). Once water is flowing out, tight the
connection.
NOTE: Filling installation with water when boiler is in use, especially if it is
very hot is strictly forbidden, as boiler’s damage or fracture may be caused.
Once heating season is over do not get rid of water from heating installation and
boiler. When required, water may be let of through blowdown connection to a drain
once it is cooled down.
