6.4. 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 THE SAS UWG BOILERS MAY BE EMPLOYED ONLY IN THE
OPEN SYSTEM INSTALATIONS, WITH PROTECTION AIDS ACCORDING TO
THE GIVEN STANDARD).
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 UWG 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. 10, 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.
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.
