PREPARATORY WORK AND SAFETY CHECKS
IMPORTANT WARNING
This stove must not be installed into a chimney that serves any other heating appliance.
Theremustnotbeanextractorfanttedinthesameroomasthestoveasthiscancausethe
stove to emit fumes into the room.
Chimney
Inorderforthestovetoperformsatisfactorilythechimneyheightmustbesucienttoensurean
adequate draught of approximately 15 Pa so as to clear the products of combustion and prevent
smoke problems into the room.
NOTE: A chimney height of not less than 4.5 metres measured vertically from the outlet of the
stove to the top of the chimney should be satisfactory. Alternatively the calculation procedure
given in EN 13384-1 may be used as the basis for deciding whether a particular chimney design
willprovidesucientdraught.
The outlet from the chimney should be above the roof of the building in accordance with the pro-
visions of Building Regulations
Approved Document J.
If installation is into an existing chimney then it must be sound and have no cracks or other faults
which might allow fumes into the house. Older properties, especially, may have chimney faults or
the cross section may be too large i.e. more than 230 mm x 230 mm. Remedial action should be
taken, if required, seeking expert advice, if necessary. If it is found necessary to line the chimney
thenauelinersuitableforsolidfuelmustbeusedinaccordancewithBuildingRegulationsAp-
proved Document J.
Any existing chimney must be clear of obstruction and have been swept clean immediately before
installationofthestove.Ifthestoveisttedinplaceofanopenrethenthechimneyshouldbeswept
onemonthafterinstallationtoclearanysootfallswhichmayhaveoccurredduetothedierencein
combustionbetweenthestoveandtheopenre.
If there is no existing chimney then any new system must be to the designation described above
and in accordance with Building Regulations Approved Document J.
Asinglewallmetaluepipeissuitableforconnectingthestovetothechimneybutisnotsuita-
bleforuseasthecompletechimney.Thechimneyandconnectinguepipemusthaveaminimum
diameter of 150 mm and its dimension should be not less than the size of the outlet socket of the
stove.
Anybendinthechimneyorconnectinguepipeshouldnotexceed45°.90°bendsshouldnotbe
used.
Combustiblematerialshouldnotbelocatedwheretheheatdissipatingthroughthewallsofreplaces
oruescouldigniteit.Thereforewheninstallingthestoveinthepresenceofcombustiblemate-
rials due account must be taken of the guidance on the separation of combustible material given
in Building Regulations Approved
Document J and also in these stove instructions.
If it is found that there is excessive draught in the chimney then a draught stabiliser should be
tted.Fittingofadraughtstabiliserwillaecttherequirementforthepermanentairsupplyinto
theroominwhichthestoveisttedinaccordancewithApprovedDocumentJ(seealsocombu-
stion air supply).
Adequate provision e.g. easily accessible soot door or doors must be provided for sweeping the
chimneyandconnectinguepipewhereitisnotintendedforthechimneytobesweptthroughthe
appliance.
Hearth
The hearth should be able to accommodate the weight of the stove and its chimney if the chim-
ney is not independently supported. The weight of the stove is indicated in the brochure.
The stove should preferably be installed on a non-combustible hearth of a size and construction
that is in accordance with the provisions of the current Building Regulations Approved Document
J.
The clearance distances to combustible material beneath, surrounding or upon the hearth and
walls adjacent to the hearth should comply with the guidance on the separation of combustible
