PREPLUMBING
With the plumbing manifold installed,
pipework can be installed to the valves on the
manifold.
The system can be filled (without the boiler
being
connected) using the charging link
assembly
(see page 23).
The valves can be closed enabling the DHW
and CH systems to be tested. The boiler can
be installed at later date.
RUNNING PIPES
BEHIND THE BOILER
If
the boiler pipes are to be
run behind the
appliance ensure that the pipes pass close to
the
wall
as shown in the diagram opposite,
and within the pipe guide.
