Pre Installation Requirements
P
LEASE CHECK THE FOLLOWING
:
Any existing chimney/flue system must be confirmed as suitable for this appliance as defined in Building Regulations
Document J. It must be swept and inspected, by a competent person (see notes), to confirm that is structurally
sound and free from cracks and obstructions. The diameter of the Flue should not be less than Ø150mm and not
more than Ø200mm. Do not connect to systems that have large voids or spaces. If any of these requirements are
not met, the chimney should be lined by a suitable method.
If the chimney is suspected of previously serving an open fire it must be swept again, within a month of regular use,
to clear any soot that may have been dislodged due to the variation in combustion levels and higher flue gas
temperature levels. The chimney/flue system exit must comply with Building Regulations Document J. The minimum
height of the chimney/flue system must be 4.5 metres and should terminate in accordance with Table 1.
Make provision to access the chimney/flue system for cleaning and the removal of debris. If there is no existing
chimney then either a prefabricated block chimney in accordance with Building Regulations Approved Document J,
or a twin-walled insulated stainless steel flue to BS4543 can be used. These chimneys must be fitted in accordance
with the manufacturer’s instructions and Building Regulations. New masonry and flue block chimneys must meet the
requirements of Building Regulations Document J. Any connecting flue pipe systems must also meet these
regulations.
Please check the suitability of the fireplace and/or surround for use with this appliance before installing it. Many Fire
Surrounds are only suitable for use with gas and electric fires and therefore may not suitable for this Solid Fuel
Appliance. Please check your Fire Surround. Fire Surround Back Panels suitable for solid fuel are usually in three
sections and slabbed.
If you have any doubts about the suitability of your chimney, consult your local dealer/stockist.
Both the chimney and flue pipe must be accessible for cleaning and if ANY part of the chimney cannot be reached
through the stove (with baffle removed), a soot door must be fitted in a suitable position
.
