Operation and maintenance manual for the Q-PER series boilers with feeders. The producer reserves the right to introduce technical modifications.
3.3. Connection to chimney
1. It is necessary to prepare stand-alone, tight chimney
fl
ue,
which will be used for
fl
ue gas from the boiler.
2. The
fl
ue should be placed at least 1.5 m over the roof ridge
to avoid the occurrence of backdraught. The intersection of
the
fl
ue should be appropriately selected for the boiler pow-
er and height of the chimney. Approximate calculations of
chimney height and intersection can be carried out using
a chimney intersection calculator available on the website
www.pereko.pl Regardless of the results of the calculations
the minimum intersection of masonry chimney should not
be lower than 14
×
14 cm! The intersection of non-insulated
steel chimneys should be bigger by 20% and the chimneys
made from steel pipes should be about 15-20% higher than
brick chimneys.
3. Check condition of the chimney (preferably by a chimney
sweep) before connecting the boiler to the chimney and
check whether the chimney if free from connections of the
heating elements.
4. The boiler should be connected with chimney using a con-
nector. It is not recommended to use the connection at a
straight angle because it will cause a loss in the chimney
draught. Flue with chimney should be joined with a connec-
tor made of steel sheet of thickness 3 mm (to be purchased
from the boiler producer). We put it on the outlet from the
fl
ue,
fi
x on the chimney and seal with high-temperature
silicone. The connector should be directed slightly up-
wards from 5° to 20°. If boiler
fl
ue will have a length over
400 mm then it is recommended to insulate it with a thermal
insulation.
NOTE! Boilers should be installed in compliance with the
applicable Regulation of the Minister of Infrastructure
(Journal of Laws of 2002 no. 75 item 690 and Journal of
Laws of 2009 no. 56 item 461.) In addition, it is recom-
mended to use chimney liner resistant to corrosion: chem-
ical, pitting, intercrystalline and surface.
3.4. Connection of central heating and domestic hot water system
3.4.1. Open water heating installations
The Q-PER boiler is suitable for supplying open water central
heating systems with gravitational or forced circulation. The
system in which the boiler operates must meet the require-
ments of the Polish standard PN-91/B-02413 Ogrzewnictwo
