INSTALLATION
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. 6)
.
For your 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.
A. High-level ventilation
B. Low-level ventilation
C. Draught stabiliser
D. Flame inspection window
E. Height of lined chimney
F. Chimney diameter

Base
The base on which the boiler will be mounted must be made from
noncombustible 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.
Chimney connector type: B23
(fig.6)
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 connector is required.

Important note:
The above table is shown by way of indication only as
regulations vary from country to country.
The high output of our boilers means that the flue
gases are at a 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 any further information.
