15 CONDENSATE DRAIN

Refer also to the British Gas document: 'Guidance Notes
for the Installation of Domestic Gas Condensing Boilers'
(1989).
Refer to Frame 21 for boiler condensate connection
detail.
The condensate drain provided on the boiler must be
connected to a drainage point, preferably within the
building.
The routing of the drain must be made to allow a
minimum fall of 1 in 20 away from the boiler, throughout
its length. (Not including an additional trap)

16 GAS CONNECTION

The boiler gas connection is built into the pre-piping frame.
IMPORTANT. The gas service cock is sealed with a non-
metallic fibre washer seal so must not be overheated when
making capillary connections.
Refer to Frame 1 for details of the position of the gas
connection.
N.B. The principle of the 1:1 gas valve ensures that the
mexico HE range is able to deliver their full output at inlet
pressures down to 14mb. However if dynamic pressures
below 20mb are experienced ensure this is adequate for ALL
other gas appliances in the property.

17 BOILER WATER CONNECTIONS

The boiler flow and return connections are built into
the pre-piping frame.
Note.
For heating loads in excess of 60 000 Btu/h use
28mm x 22mm connectors to connect the boiler flow
and return pipes to 28mm.
If flow and return pipes are required to run behind the
boiler, this can be facilitated by fitting the boiler in line
with the front of 600mm deep kitchen units thus
creating a 70mm space behind the boiler.

INSTALLATION
Note. A condensate drain pump kit is available as an optional extra if required.
The drainage pipework must be arranged so that
obstruction (e.g. through freezing) of external drainage pipe
does not give rise to spillage within the dwelling.
All pipework and fittings in the condensate drain system
must be made of plastic. No other materials may be used.
The drain outlet on the boiler is standard 21.5mm overflow
pipe. This size must not be reduced in any part of its
length.
A boiler gas supply pipe length of 20m and not less than
15mm O.D. can be connected to the boiler via the gas
service cock union.
Ensure that the gas supply pipe does not foul the boiler
casing.
Refer to Frame 40 for details of the pressure test point
position.
