Stratford EcoBoiler Stove
INSTALLATION
Due to the gradual introduction of European Chim-
ney Standards chimneys will be specified accord-
ing to their performance designation as defined in
BS EN 1443 that covers the General Requirements
for chimneys. The minimum performance designa-
tion required for use with solid fuel burning stove is
T450 N2 S D3
The flue and chimney installation must be carefully
checked by a competent person before fitting the
stove to ensure it is suitable and will work safely.
If the chimney is old (i.e. built of brick or stone with
out a liner) or being opened up for reuse additional
checks and smoke testing as described in Appendix
E of Approved Document J 2002 Edition should be
carried out to ensure the flue and chimney are in
good operating condition.
Unless the existing flue is in good condition with
suitable access for collection and removal of debris,
the flue size is more than 225mm (9”) diameter, or
200 x 200mm square, a suitable lining of 150mm
(6”) diameter should be fitted. If the flue length is
over 5.5metres one size larger than the appliance
outlet should be fitted, (6” min.). This should be a
double skin stainless steel flexible flue liner that is
independently certified for use with solid fuel. De-
tails of suitable linings for use with wood and solid
fuel are given in the official
HETAS guide that can
be viewed on their website at www.hetas.co.uk -

It is also important that a suitable flue pipe that com-
plies with the building Regulations is used to con-
nect the stove to the flue in the chimney and that
suitable access is provided into the flue for regular
inspection and sweeping of the flue ways.
The installer should comply with the Building Regu-
lation requirements in respect of providing a notice
plate giving details on the chimney, flue lining,
hearth and fireplace installation. Approved Docu-
ment J of the building regulations for England and
Wales is available from The Stationary Bookshops
and can also be viewed at the ODPM website at
www.safety.odpm.gov.uk/bregs/brads.htm
Details on the relevant Building Regulations and BS
British Standards are given in the ‘General Precau-
tions’ section of this manual.
Chimneys should be as straight as possible.
Horizontal runs should be avoided except where
the rear outlet of the appliance is used, in which
case the horizontal section should not exceed
150mm (6”) in length.
If the fire appears to be working hard but pro-
duces very little output to the room it is likely that
excessive draw is present in the chimney, and
that heat is being sucked out of the appliance and
up the chimney.
If this is the case we recommend the fitting of a
draught stabiliser in preference to a flue damper,
in the interests of safety and efficiency.
FOR ALL APPLIANCES
Access for cleaning the flue should be
incorporated in the system other than through
the appliance (e.g. a soot door or access though
the register plate). Purpose made soot doors and
inspection lengths are available from manufactur-
ers of all flue system.
Ensure that the whole length of the flue can be
reached from the soot door.
Note: if the appliance is fitted with a draught
stabiliser or if one is fitted to the flue pipe or
chimney in the same room as the appliance,
then the permanent air entry opening (or
openings) should be increased by 300mm² for
each kW of rated output.
