WATER CONNECTION
Fit the supporting hooks and attach the assembly template, moving it up to the wall; fit all the pipes, starting
with the end pipe fittings already mounted on the template: system supply, system return, cold water, hot water,
any gas pipes and electric mains leads with room thermostat.
Once the pipes have been fitted, the end pipe fittings can be removed and ordinary caps fitted, ready for
hydraulic tests to be carried out. The template can be removed or, if left in place, will be embedded in the wall
once finishing operations have been completed (plaster and tiles); only the two supporting hooks will protrude
from the wall, as well as an opening for the connections. Attach the boiler to the hooks through the holes at the
back of the frame, pushing it up against the finished wall. Make the necessary hydraulic connections.

-
Do not use pipes of reduced diameter.
-
Do not use low-radius elbows or fit-
tings that significantly reduce cross-
section.
-
Hot-flushing of the system is recom-
mended
in order to eliminate any im-
purities from the piping and radiators
(especially oil and grease) which
might
damage the circulator
.
