For boiler to be used, it is not required to apply flue insert, however in year
round exploitation – it is recommended to provide heating to the hot utility
water container.
5.4. CONNECTING BOILER TO HEATING INSTALLATION
The boiler should be connected to heat in installation with screw connectors.
Protecting measures for water heating installations of opened type should be
according to detailed regulations being in force in the country of destination (e.g.PN-
91/B-02413).
Volume of pressure vessel should be equal at least 4% volume o water in the entire
heating installation.
NOTE: Ascending and descending safety pipe as well as circulation pipe
must not be equipped with any valves. In addition, those pipes and the
pressure vessel should be protected against freezing.
Boilers of SAS MULTI type may work with gravitational or forced water circulation. If
installation is provided with circulation pump, than on feeding/return pipe the
differential valve should be installed. When blackout or pump malfunction occurs, this
valve will open and the system start work running by gravitation.
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 –
EXPLOITATION PARAMETERS p. 7, point 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.
5.5. 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).
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)
