4. CHIMNEY
Chimney of appropriate height and diameter is very important for proper operation of boiler. Before connecting the
boiler to the chimney, check if its flue is suitable (diameter of flue must be not lower than of boiler’s flue), if there are
other systems connected to the chimney. Chimney must be installed according to current standards and regulations.
Chimney’s draft must be 20-25 Pa. If draft is low, boiler will operate poorly (buildup of resins, congestion, smoking) and
it‘s service life will be shorter.
NOTE
In order to prevent chimney’s performance deterioration, caused by rain water steam and buildup of
resin, it must be impermeable and isolated.
In case of excessive draft, there will be increase in fuel consumption and in extreme cases there is a chance of
overheating the device. This flaw can be eliminated by installing draft limiter. Chimney sweep must assess the technical
condition of chimney which will be connected to boiler. In order to safeguard the system form wind gusts, chimney
must rise no less than one meter above the roof. Premise, in which the boiler will be installed, must meet the
requirements of “the rules of installing solid fuels boilers in buildings ST 8860237.02:1998”.
Chimney must meet specific regulations, of the country where it is being installed.
Lowest dimensions of flue recommended by manufacturer of boiler:
•
Round cross-section – 150 mm
• Square cross-section – 140 x 140 mm
Boiler‘s flue must be connected to chimney’s steel part of suitable size and form.
Connection must be leak-proof.
