6.1.1 Connecting the heating circuit
Connect the heating circuit with flat seal screw connections to boiler flow
and boiler return.
Disconnector valves have to be installed into the flow and return. To facili
tate the assembly, the shut-off set ADH (accessory) or AEH (accessory)
may be used.

Note
Install heating filter.
Installation of a filter is recommended in the heating return. In the
case of old plants, the whole heating plant should be thoroughly
flushed before installation.
6.1.2 Safety valve
Mount the membrane expansion vessel with the heating systems closed.
Caution
The connecting pipe between boiler and safety valve must not be
blockable.
The installation of pumps and fittings or pipe reducer pieces is not
permissible. The blow-off line of the safety valve must be de
signed in such a way that the pressure does not increase when
the safety valve responds. It must not be routed to the outside, the
opening must be clear and observable. Any heating water that
may possibly escape should be safely drained off.
Caution
The blow-off line of the safety valve must be designed in such a
way that the pressure does not increase when the safety valve re
sponds. It must not be routed to the outside, the opening must be
clear and observable. Any heating water that may possibly escape
should be safely drained off.
6.1.3 Condensate
A direct run-off of the condensate into the domestic drainage system is on
ly allowed if the system only comprises corrosion-resistant materials (e.g.
PP-pipe, stoneware or similar materials).
The condensate must be able to flow freely into a funnel. A stench trap
must be installed between the funnel and drainage system.
The condensate hose of the Paramount four must be inserted through the
opening in the floor.
If there is no run-off facility underneath the condensate discharge, the use
of Potterton Commercial neutralisation and lifting system is recommended.
