BOILER MOUNTING
6
It is recommended to always keep clean the grate, in order to ensure long life and correct
ignition.
Do not ever use inflammable materials for manual ignition of the boiler!
Before any work of maintenance is effected, please turn off the boiler and disconnect from
electricity.
Do not open the boiler door during function!
Do not introduce any other materials for combustion in the pellet tank, or manually
in the grate, other than wood pellets!
3.3.
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 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
cross-section and total height of the chimney must be correctly calculated to ensure natural
draught.
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. If the total route of
the chimney pipe is more than 10 m, it is recommended to use a 100 mm chimney pipe.
It is prohibited to change the exhaust diameter by any means or reduction
between the boiler outlet and the vertical chimney pipe!
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 terminal must always be installed perpendicular to ground!
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.
Each boiler should be connected to an independent chimney. Connection of multiple
boilers to the same chimney is not recommended.
It is prohibited to use as a chimney flexible aluminum tube!
