All measures are in mm
Fig. 6.1
• When installing the boiler in a cupboard,
cover or alcove allow at least 5 mm per-
manent clearance from the front face of the
boiler. Also ensure sufficient clearance to al-
low free access for servicing and the lower-
ing of the front control panel.
• If the boiler is installed outside, cover the
appliance to protect it against the elements
and add some special anti-freeze (neutral-
ised) to the c.h. system.
• Before installing the boiler on an existing c.h.
system, flush it out thoroughly before fitting
the boiler, so as to remove muddy deposits.
It is advisable to equip the system with a sedi-
ment filter, or use a water-treatment product in
the circulating water.
The latter option in particular, not only cleans
out the system, but also has an anti-corrosive
effect by promoting formation of a protective
skin on metal surfaces and neutralising gases
present in the water.
We recommend the use of a suitable universal
inhibitor to protect the c.h. system from cor-
rosion.

Precautions
Before mounting the bracket, check that the
dimensions for fitting the exhaust fume duct
are complied with (refer to the leaflet included
25
with the flue kit, packed separately).
Utilise the paper template supplied with the
boiler to determine the fixing position for the
bracket and boiler. Securely mount the brack-
et to the wall using appropriate fixings suitable
for the type of wall construction and capable
of supporting the total (wet) load. Refer to the
weight given in the technical data tables spe-
cific for each model.
