IMPORTANT
Because of the improved efficiencies of boilers under E.U. Efficiency
requirements and OFS 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 23.
Conventional Brick Chimney With Liner
NOTE:
All brick chimney constructions must com-
ply with current building regulations and
BS 5410: Part 1. Insulated factory made
chimneys should comply with BS 4543.
