tions.
Connect manifold unions to the boiler.
1.5
Water circulation system
The central heating system should be installed in accordance
with BS.6798 and, in addition, for smallbore and microbore
systems, BS.5449 or EN 12823.
1.6
Pipe connections
Pipework from the boiler is routed downwards as standard, but
may be routed upwards behind the boiler using the wall
spacing frame (supplied with the boiler).
Connect pipes as shown in fig. 4. Ensure that all pipework
is routed so as to minimise any strain on the boiler fittings.
Buderus advises to use copper piping for the first 600 mm,
then it is allowed to switch to another approved pipe material.
CAUTION!
Do not use galvanised radiators or pipes.
1.6.1
Gas Supply
The gas installation must be installed in accordance with
BS.6891.
CAUTION!
Pipework from the meter to the boiler MUST be
of adequate size, generally at least Ø22 mm.
The complete installation MUST be tested for gas tightness
and purged as described in IGE/UP/1b.
Subject to modifications resulting from technical improvements!
