INSTALLATION
BOILER ROOM
Important
•Keep vents free at all times.
•Do not store inflammable products in the boiler room.
•Do not store corrosive products near the boiler, such as paints, solvents, chlorine, salt, soap and other cleaning products.
•If you smell gas, do not switch on the light or light a flame. Turn off the mains gas tap at the meter and inform the appropriate services immediately.
Access
The boiler room must be large enough to allow good access to the boiler. The following minimum distances are required around the boiler:
- front | 500 mm |
- side | 100 mm |
- behind | 150 mm |
- above | 700 mm |
Ventilation
The boiler room must be fitted with top and bottom vents sized according to the table below or to current regulations.
CHIMNEY CONNECTIONS
IMPORTANT
Boilers must be installed by an approved heating engineer, in accordance with the prevailing local standards and regulations.
Flue size should not be less then the outlet size of the boiler.
Chimney connection type: B23
The boiler is connected to the chimney by a metal pipe rising at an angle from the boiler to the chimney.
A flue disconnection piece is required.
This must be easy to remove to give access to the flue pipes when servicing the boiler.
The table below gives an example conforming to the Belgian standards.

Note:
Regulations vary from country to country therefore the table above is intended only as a guide.
Due to the high efficiency of our boilers, the flue gasses exit at low temperature. Accordingly, there is risk that the flue gasses could condense, which could damage the chimney. In order to avoid this risk, it is strongly recommended that the chimney be lined.
