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

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 boiler room must be fitted with top and bottom vents according to the prevailing local standards and regulations.

The table below gives an example conforming to the Belgian standards.

Ventilation		71	101
Min. fresh air requirement	m3/h	126	194
Bottom vent	dm2	2.4	3.20
Top vent	dm2	2.0	2.0

Other countries should refer to their own standards.

Base

The base on which the boiler rests must be made of non-combustible materials.

E = 15 m Ø F min.	mm	150	150

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.
