3.2.2.
Boiler room dimensions
The boiler must be placed on a horizontal plane, with adequate mechanical resistance to support
the boiler’s weight. The boiler must be positioned in the room in such a way so that it is easily
accessible from all the sides. The following dimensions are recommended (see Fig 2):
The distance between the boiler and the back
wall - is the proper distance that allows easy
access for inspection and maintenance.
The distance between the boiler and side wall -
at least 0,6 m.
The height of the boiler room - at least 2 m.
Access and service spaces of boiler room and hall
doors paths will always be free.
In the boiler room will be displayed operating
instructions, taking into account the specificities
of the boilers mounted. Also, you will see internal
instructions of staff and service duties.

Chimney
The chimney installation must supply sufficient draught, air tightness and protection against
condensation.
The appropriate chimney installation is very important for the boiler’s efficient
and safe function!
The chimney must be positioned if possible in the interior of the building. It must be vertical,
with no changes in the direction. The cross-section of the chimney can be round or rectangular.
If the chimney is installed in the exterior, it must be insulated.
The horizontal part connecting the boiler’s chimney pipe with the vertical chimney must have
maximum length 2 m. If this distance is bigger, it is recommended to have a 15-30
o
inclination
upwards. The connection with the boiler’s chimney pipe must be air-tight.
The chimney must be equipped with a cleaning door at its base. Also cleaning doors are
recommended where there are changes in direction and ash can be accumulated. Tactical
cleaning is recommended (every 3 months) for efficient boiler function.
A chimney terminal must be installed at the end of the chimney for protection against weather
effects and foreign objects entrance. In areas with strong winds a special anti-downdraught
terminal is recommended.
The chimney height must exceed the roofline by at least 1 m. If there are other obstacles
positioned on the roof, the chimney height must exceed them by at least 1 m. If there are
multiple chimneys, minimum distance between them is 0,3m.
