Pressure Relief Valves
The pressure relief valve on this module is pre-
set at 3 bar.
Install a pressure relief valve discharge pipe to
the valve, not less than 15 mm diameter and
connect to the tail pipe using a 15mm
compression fitting. The pipe run should be as
short as possible, run continuously downwards
and discharge to the outside of the building,
where possible over a drain.
The pipe end should be directed towards the
wall. The discharge point must be such that it will
not be hazardous to occupants or cause damage
to external electrical components or wiring.
IT MUST NOT DISCHARGE ABOVE AN
ENTRANCE, OR WINDOW, OR ANY TYPE OF
PUBLIC ACCESS. THE INSTALLER MUST
CONSIDER THAT THE OVERFLOW COULD
DISCHARGE BOILING WATER.

Venting the Boiler

The system can now be filled by connecting the filling
loop or opening the isolating valves. Pressurise and
top up to 1 Bar. Check for leaks. The pump must be
properly vented, it should NOT be run dry (this may
cause damage to the bearings).
Disconnect the filling loop.
