LAYOUT OF CONNECTIONS
CONNECTION TO HYDRAULIC SYSTEM
Connect the water and central heating
pipes to the boiler, respecting the positions
and distances indicated (Pict. 12); take
particular care when connecting pipes to
ensure they are not placed under pressure
in order to minimise the danger of future
leaks. Use appropriate tools and procedures
for tightening.
Before connecting the pipes:
Clean the pipes and the radiators
thoroughly to make sure that any
impurities which may be there are
completely removed.
Connect the safety valve outlet
so that its operation will not
cause any damage to persons
or property.
• Use piping of not less than 1/2”
diameter
• Ensure that the line is always at
atmospheric pressure by using
suitable traps (do not connect
pipes directly to the valve outlet)
• Connect the safety valve outlet
line to the household grey water
drainage system
• Apply suitable protection to the
drainage line – the water carried
in it may be at high temperatures
• The manufacturer assumes no
responsibility for damage caused
to persons or property due to
operation of the safety valve
Do not use the plumbing pipework
connections as earth points for
electrical equipment
