CAUTION!
Work on gas-bearing components may only be
carried out by a CORGI registered installer.
For the size of the pipe connection please refer to the wall
mounting template.
Connect the boiler to the gas supply in accordance with the
relevant standards. Fit the supplied service valve in the gas
feed line. Connect the pipe free of tension (fig. 7).
Fit a gas service valve with a size of R¾ on type 800 – 60.
1.7.4 Hot water connection
On type 800 – 24/29/43/60:
Connect the external storage-type water heater in accordance
with the appropriate installation instructions using the connec-
tion kit.
On type 800 – 24T25 H/V and 800 – 29T25 H/V:
CAUTION!
Do not use galvanised pipes or fittings. The hot
water heat exchanger is made of copper and
risks electrolytic corrosion.
When using plastic pipes, note the information provided by the
pipe manufacturer. This particularly applies to the mode of
connection recommended by manufacturer.
In certain situations to prevent hammering within the
system when closing taps, controls can be installed to
counter act this action. For further information please
contact Buderus.
For the size of pipe connections please refer to the wall
