BOILER ROOM
Important
• Never obstruct the ventilation.
• Do not store inflammable products in the boiler room.
• Avoid storing corrosive products such as paint, solvents, chlorine,
salt, soap or other cleaning products near the boiler.
Accessibility
The boiler room should be big enough to allow easy access to the
boiler. Minimum clearances around the boiler (mm):
- to the front
500
- to the rear
150
- to the sides
100
- above
700
Ventilation
The boiler room must have both low and high level ventilation
(see
Fig. 3)
.
By way of information, the table below gives the minimum
ventilation requirements according to Belgian regulations.
The user must ensure that his boiler room ventilation complies
with local regulations.
Chimney connector type: B23
(Fig.3)
The chimney must be connected to the boiler by means of a metal
pipe rising at an angle from the boiler to the chimney.
A chimney connection is required.

Base
The base on which the boiler will be mounted must be made from
non-combustible materials.
CHIMNEY CONNECTIONS
IMPORTANT
The boiler must be installed by a qualified engineer in
accordance with the local standards and codes of
practice.
The diameter of the chimney must not be less than the
diameter of the boiler's chimney reducer.

Important note:
The above table is shown by way of indication only as
regulations vary from country to country.
The high efficiency of our boilers means that the flue
gases exit at low temperature. The attendant risk of
condensation may cause damage to some chimneys.
To avoid this risk we strongly advise that you line the
chimney.
Please contact your installer for further information
about chimney lining.
