WATER CONNECTION
Fit the supporting hooks and attach the assembly template, moving it up to the wall; fi t all the pipes, starting
with the end pipe fi ttings 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 fi tted, the end pipe fi ttings can be removed and ordinary caps fi tted, 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 fi nishing 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 fi nished wall. Make the necessary hydraulic connections.
ADVICE AND SUGGESTIONS ON PREVENTING SYSTEM VIBRATION AND NOISE.
-
Do not use pipes of reduced diameter.
-
Do not use low-radius elbows or fi ttings that signifi cantly reduce cross-section.
-
Hot-fl ushing of the system is recommended in order to eliminate any impurities from the piping and radia-
tors (especially oil and grease) which might damage the circulator.
