BOILER ROOM
ACCESSIBILITY
The boiler room must be large enough to allow proper access to
the boiler. The following minimum distances around the boiler are
required
- at the front: 500 mm
- above: 300 mm
- on the central heating connection side: 150 mm
This boiler can be connected to the central heating circuit in any one
of three directions.
BASE
The boiler must be laid on a base made of non-combustible materials.
CENTRAL HEATING CONNECTION
The drain cock (9) and safety valve (2) must be connected to the
waste water disposal system.
The boiler is fitted with an expansion chamber with a
capacity of:

DOMESTIC HOT WATER CONNECTION
Pressure reducer
If the water mains pressure is greater than 6 bar, a pressure reducer
calibrated to 4.5 bar must be fitted.
Safety unit
The tank safety unit must be ACV approved and calibrated to 7 bar.
The valve discharge must be connected to the waste water disposal
system.
Domestic hot water expansion tank
Installing a domestic hot water expansion tank avoids any risk of
overpressure due to pressure surges and also makes sure that there
is a always water flowing through the safety unit when refilling the
domestic hot water tank.
Hot water circulation
If the tank is located a long way from the point of use, then installing
a closed recirculation circuit ensures that a faster supply of hot water
is always available.
