It is important that adequate ventilation exists and the
flue or chimney system that is to be used is in good
working condition. Products of combustion that enter the
room could be a serious health risk. Before installation of
this product we recommend that the flue or chimney
system and ventilation requirements are inspected by a
competent person, and passed as suitable for use with the
appliance to be fitted. In particular the following should
be checked: -
1.1 The construction of the flue or chimney system should
meet the requirements of the Building Regulations with
sizes as shown: -
1.2 An approved, factory made system suitable for solid fuel
use, complying with BS 4543: Part 2, may be used when
installed to the requirements of BS 7566: Parts 1 to 4, the
manufacturer’s instructions and the requirements of
Building Regulations.
1.3 New masonry chimney systems built with clay or concrete
liners or pre-fabricated block systems should be
constructed in accordance with BS 6461 : Part 1, and the
requirements of Building Regulations.
1.4 A flexible flue liner system may be used, if it is
independently certified for use with solid fuel systems,
and is installed according to the manufacturer’s
instructions and the requirements of Building
Regulations. If an appliance is being replaced on an
existing flexible flue liner system, the liner system should
be replaced, unless it can be proved to be recently
installed and can be seen to be in good condition.
1.5 The flue exit from the building should be positioned to
comply with the requirements of the Building
Regulations.
1.6 Any existing flue should be confirmed as suitable for the
new intended use, as defined in the Building Regulations.
1.7 Any existing flue or chimney system must be inspected
and swept by a NACS registered (GB only) chimney
sweep, to confirm that the system is structurally sound
and free from any obstructions.
1.8 Suitable access should be provided to enable the
collection and removal of debris.
1.9 Provision should be made to sweep and inspect the flue
when the appliance is installed.
1.10 No other heating appliances should be connected to, or
share, the same flue or chimney system.
1.11 Check the flue draught. This should be done with all
windows and doors closed and any extraction fans in this
or adjoining rooms running at maximum speed (see next
section for additional ventilation requirements).
