chimney.
• Access for sweeping.
• Leakproof connections.

Accumulator system - control
The boiler must be connected to an accumulator
system with accumulator control.
The accumulator control prevents the return temperature
to the boiler being too low, which minimises the risk
of condensation in the combustion chamber. The
accumulator system’s charging pump is controlled
by the boiler’s control equipment.
Pipe connections
The pipes to the accumulator system must be as
short as possible, with as few bends as possible.
The pipes must be laid to eliminate air pockets
and to achieve self-circulation.
The minimum recommended pipe dimension is 1.1 in
for Vedolux 350 and 450, and 1,38 in for Vedolux 650.
Expansion system
The volume of the expansion tank is dimensioned
according to the prevailing conditions. The
recommended values for this are that the volume,
for an open system, must be approximately 5% of
the system’s total volume or approximately 15% for
a closed system.
To avoid oxygenation of an open expansion system,
the distance between the highest point of the heating
system and the expansion tank must not be less than
98.5 in.
The expansion tank is connected in an unisolatable,
uninterruptible rise from the boiler’s expansion
connection.
To avoid damage in the event of any
blockage in the expansion system, the
boiler should be fitted with a safety valve.
In a closed system, the boiler must be fitted with a
vent valve and an approved safety valve, connected in
an uninterruptible connection from the connection on
the top of the boiler. The drainage pipe of the safety
valve must be laid to the floor drain with the mouth
visible.
