4-A: Important Notice
Because of the improved efficiencies of boilers under E.U. Efficiency requirements and
OFT A100 Standard, it is necessary to pay extra special attention to flues and chimneys.
The improved efficiency figures achieved by modern oil boilers are attained by using
more of the heat (higher temperatures) heretofore allowed into flues and chimneys. This
previously wasted heat helped to keep bad and poorly operating and often uninsulated
flues and chimneys from condensing and causing problems. Please be fully aware of this
when replacing an existing boiler. An old and poorly operating flue may need to be
replaced to take full advantage of improved efficiencies and to avoid flue gases
condensing and appearing as white water vapour (pluming) at flue (chimney) outlet.
New flues and chimneys should be properly insulated and constructed to prevent
condensation and draughting problems. Every individual concerned with any aspect of
installation should be aware of the foregoing and should have full knowledge of and
work to European, National and Local Govt. Standards and Building
and Installation Regulations .
These manufactures instructions must not in any way be mis-interpreted as over-riding
the above or any statutory regulations. It is absolutely essential that the boiler is properly
installed so that NO FLUE GASES can enter the building at any time. Flue pipes should
be safely sealed into the wall to prevent flue gases re-entering room or building
Refer also to page 16.
PREPARING BOILER FOR CONVENTIONAL
CHIMNEY/FLUE OPERATION
Before installing boiler in the above mode please ensure:
A . That chimney flue is cleaned, draughting adequately, lined if necessary and
not subject to downdraughts.
It is emphasised that boiler and flue should be
connected properly in a manner which will not allow flue gases to enter room or
building at any time from any part of the installation.
B . That adequate unrestricted air for combustion and ventilation is provided to
room in which boiler is situated - see diagram pg.20 & 21.
C . That there is no extractor fan capable of
causing negative pressure in boiler room resulting in
burner malfunction and flue gases being drawn back
into boiler room.
Conventional Flue Installations-
1 . Remove blanking plate from top panel by
pulling backwards.
2 . Fit trim sleeve to flue pipe (if supplied).
3 . Slide upwards and ‘park’ it out of the way
4 . Fit flue pipe into boiler socket and properly seal with high
temperature silicone mastic or non-cracking fire cement.
5 . Fit white enamel top panel
6 . Fit cut-out cover plate behind flue pipe (shown in diagram)
7 . Slide trim sleeve down against top panel
(If Supplied)
ENSURE UNRESTRICTED AIR-SUPPLY TO BOILER ROOM . No further
adjustments are required for adequate combustion-air supply. Check burner
operation when installation is completed, use burner
Combustion Analyser
to ensure correct performance.
Consult separate burner manual supplied with boiler.
