Water Circulation System; Pipe Connections - Buderus 600 - 11S Installation And Servicing Instructions

1 Installation
1.6

Water circulation system

The central heating system should be in accordance with
BS.6798 and, in addition, for smallbore and microbore
systems, BS.5449.
1.7

Pipe connections

Pipework from the boiler is routed downwards as standard, but
may be routed upwards behind the boiler using the stand-off
frame (supplied in a separate kit).
Connect pipes as shown in fig. 6. Ensure that all pipework
is routed so as to minimise any strain on the boiler fittings.
1.7.1 Gas Supply
The gas installation must be installed in accordance with
BS6891.
CAUTION!
Pipework from the meter to the boiler MUST be
of adequate size.
The complete installation MUST be tested for gas tightness
and purged as described in IGE/UP/1b.
1.7.2 Gas connection
Connect to gas supply according to relevant standards,
installing a screw-threaded gas shutoff valve (accessory)
to the gas supply system.
1.7.3 Hot-water temperature for 600 - 24C
CAUTION
DO NOT use galvanised pipes or fittings.
The hot water heat exchanger is made of
copper and is liable to suffer the effects of
electrolytic corrosion.
NOTE
When using plastic pipes, observe the
supplier's instructions - especially those
referring to recommended jointing techniques
and the notes relating to the heating system
water on page 5.
Fit a non-shutting diaphragm safety valve (max. 8 bar)
upstream of the cold-water inlet. This is not required if the
building is equipped with a pressure regulator configured to
guarantee that the maximum supply pressure of 10 bar
cannot be exceeded.
Connect pipes free of tension (fig. 6).
Subject to modifications resulting from technical improvements!
