•
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 suffi cient clearance
to allow free access for servicing and the
lowering 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, fl ush it out thoroughly be fore-
fi tting the boiler, so as to remove muddy
deposits.
It is advisable to equip the system with a
sediment fi lter, 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 neu-
tralising gases present in the water.
We recommend the use of a suitable uni-
versal inhibitory to protect the c.h. system

from corrosion.

Precautions
Before mounting the bracket, check that the

suitable for the type of wall construction and
capable of supporting the total (wet) load.
Refer to the weight given in the technical
