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):
- at the front 500
- at the rear 150
- at the sides 100
- above 300
Ventilation
The boiler room must have both low and high level ventilation
(see Fig. 5).
The user must ensure that the boiler room ventilation complies
with current local regulations.
By way of information, the table below gives the minimum
ventilation requirements according to Belgian 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 or flooring on which the boiler will be placed must be made
from non-combustible materials.
CHIMNEY CONNECTIONS
IMPORTANT
The boiler must be installed by a qualified engineer in
accordance with 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 connection type: B23 (Fig. 5)
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.

Note:
The above table is shown by way of information 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 details
about this.
