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).
By way of information, the table below gives the minimum
ventilationrequirementsaccordingtoBelgianregulations.
The user must ensure that his boiler room ventilation
complieswithlocalregulations.
