BOILER ROOM
Important
•Keep vents free at all times.
• Do not store inflammable products in the boiler room.
•Take care not to store corrosive products near the boiler, such as
paints, solvents, chlorine, salt, soap and other cleaning products.
Access
The boiler room must be large enough to allow good access
to the boiler. The following minimum distances (mm) are required
around the boiler:
- front 500
- behind 150
- sides 100
- above 700
Ventilation
The boiler room must be fitted with top and bottom vents as shown
in illustration "L".
The table below is an example compliant with the Belgian
standard.
Note:
(B) and (C) only for B23 type connections
For other countries, refer to their regulations.
Base
The base on which the boiler rests must be made of noncombustible
materials.
CHIMNEY CONNECTIONS
IMPORTANT
Boilers must be installed by a qualified heating
engineer, in accordance with the prevailing local
standards and regulations.
The chimney diameter must not be less than the
diameter of the boiler connection.
Chimney connection type: B23 (See illustration L)
The boiler is connected to the chimney by a metal pipe
rising at an angle from the boiler to the chimney.
A chimney connection is required
A. Top vent
B. Bottom vent
C. Draught regulator
D. Inspection cover
E. Chimney height
F. Chimney diameter
Note:
Since the regulations vary from one country to
another, the table above is given for information only.
Due to the high efficiency of our boilers,the flue gases
are released at high temperature.
Therefore there is a risk of condensation in these flue
gases, which could damage some chimneys.
To avoid this risk, it is strongly recommended to line
the chimney.
Contact your installer for more information.
Chimney connection type: C…
(see illustrations M and N)
• C 13 : concentric horizontal connection
• C 33 : concentric vertical connection
• C 43 : Concentric chimney connection
Maximum length for concentric type : 6 metres
Note:
A pipe bend of 90° = an equivalent length of one metre
There should be a drain outlet close to the boiler to
prevent chimney condensates entering the boiler.
To prevent condensation water running out of the
terminal, all horizontal pipes should slope down to the
boiler.
