3.7 - DOMESTIC HOT WATER CONNECTIONS
(with optional kit)
WARNING!
Before connecting the boiler to the water
mains supply ensure that the system is
flushed out with a suitable product in order
to eliminate any metallic tooling or welding
residues, oil and grime which could reach
the boiler and affect the proper running of
the boiler.
Non-observance of these instructions could
cause injury to persons, animals or damage
to property.
The manufacturer shall not be held liable for
any such injury and/or damage.
The hot water distribution and domestic hot water supply
pipework must be connected to their respective 3/4“ boiler
pipe connections C and F as indicated.
The pressure in the system must be between
1and 3 bar (if the pressure is higher fit a reducing
pressure valve).
Ensure yourself that the system’s water and
central heating piping are not used as earth
clamps for the electrical or telephonic system.
They are absolutely unsuitable for this use.
In a short time this could cause serious damage
to the piping, boiler and radiators.
