Pipe connections

CAUTION!
Ensure that all pipework is routed so as to
minimise any strain on the boiler fittings.
CAUTION!
Buderus advises to use copper piping for the first
600 mm, then it is allowed to switch to another approved
pipe material.
Take the CH flow connection pipe and the CH return
connection pipe out of the box and connect to the
condensing gas boiler (fig. 4, item 1 and 2).
Connect the central heating system to these pipe
connections according to the relevant standards.
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.
CAUTION!
The complete installation MUST be tested for gas
tightness and purged as described in IGE/UP/1b.
1.6.2 Gas connection
A gas service valve is supplied with the unit. Take it
out of the box and connect it to the boiler see fig. 4,
item 3 with approved P.T.F.E.-tape. Connect to gas
supply according to the relevant standards.
1.6.3 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.
1.6.4 Condensate removal
Positioning and termination of the condensate drain
pipe
The condensate pipe should be run and terminate
internally to the house soil and vent stack or waste pipe.
Alternatively, the condensate can be discharged into the
rainwater system if connected to a foul water draining
system, or into a purpose-made soak away (condensate
absorption point).
All connecting drainage pipework should generally have
a fall of at least 2.5° to the horizontal, or approximately
50 mm per metre of pipe run. If this is can not be
achieved, consider the use of a condens pump.
