The primary pump must be mounted on the return line
(See INSTALLATION EXAMPLES).
Installation of primary and secondary pumps to the
installation and wiring of the power supply cables are
in responsibility of the installation / mechanical /
electrical teams.
The power supplies of all primary and secondary
pumps are provided via the boilers’ electrical panel.
The switch-on signal to the contactors in the electrical
panel is sent by the signal cable from the terminals
Q1-Q2-Q3 located on the back of the boilers.

The use of an unsuitable primary pump can result
an uneconomic, uncomfortable operation and
damage to your boiler and your installation. The
manufacturer is not liable for damages that may
arise from such situations.
4.3 FLUE CONNECTIONS
Flue and chimney connections must be carried out in
accordance with applicable regulations and relevant
standards. Materials which are used for the flue and
chimney must be resistant to the temperature, corrosive
effect of condensation water and mechanical stresses and
must be gas-tight.
Never use the new boiler with the flues which
are used for solid/liquid fuel boilers or shunt
chimneys.
Chimney system and the condensation
drainage systems connected to it should be
checked once a year and cleaned if necessary.
