ABOUT YOUR INSET STOVE
This Inset is a solid multi-fuel heating stove designed to fit into
masonry fireplaces. It has convection chambers behind, above, at
the sides and even underneath the firebox to collect hot air and
distribute it into the room so that it is every bit as efficient, or more
so, than a free-standing stove.
INSTALLING a stove is a 'controlled service', the law expects that
it is either supervised by a qualified installer or that the building
inspector is informed. Check with your local authority.
ASBESTOS: Your stove does not contain asbestos, but take care
to avoid disturbing asbestos in an old installation.
WEIGHT: Your stove is heavy (94kg) take great care when moving
it and ensure that the intended fireplace can support the weightconsider fitting a load distributing plate.
YOUR CHIMNEY, by becoming warm, makes the gas inside it
rise, pulling fresh air into the stove to make it work. It must:
•Generate a draught in use of at least 12Pa (0.05ins wg)
•Be capable of withstanding the temperatures generated.
•Be absolutely incapable of leaking fumes into the dwelling
•This may commonly be achieved by it:
•Being at least 5m high.
•Terminating at least 1m above any roof ridge.
•Having an internal cross-section equivalent to never less than
125mm diameter, and never more than 0.14m² (eg 375 x
375mm)
•Being free from even the slightest crack or source of leakage.
•Having no bends sharper than 45º.
•Being swept and entirely free of obstructions
•Being connected only to this one appliance.
•Being of thick masonry or otherwise highly insulated.
•Conforming to local building regulations.
Special rules apply where the flue passes through timber, thatch or
other vulnerable materials- take specialist advice.
Although it is possible to access the chimney through the fire with
the throat plate removed, fit hatches to provide access if needed.
YOUR FIREPLACE: Stoves become VERY hot, the setting must
be made entirely of durable fireproof materials. Thin (<50mm)
stone slabs risk cracking unless cut into sections to allow for
expansion and backed with a heat resistant concrete. Even
beyond the safety clearance items can still become very hot - take
great care in siting wax, paper etc.
AIR SUPPLY: Your stove needs air to breathe - there should be a
permanent fresh air supply into the space in which it is installed
equal to about 550mm² for each kW of nominal output.
This degree of air can often be provided by leakage around door
frames etc, especially in older buildings. It is commonly accepted
that this alone may suffice for appliances below about 5kW output.
It must be a matter for the judgement of the installer as to whether
an extra permanent air vent is required. Where is needed, it is
wise to fit an outside vent as close to the fire as possible, to
prevent unpleasant draughts. An extractor fan, or another fuelusing appliance in the same building, can remove this air.
FITTING
This model can fit straight into a standard British or Irish fireplace
conforming to BS1251 & BS8303. The fireplace can be of any
shape, but will always have:
• Have an opening width (A) of between 400 and 420mm,
• An opening height (B) of between 540 and 560mm,
• A flat area (C) extending 70mm around the opening
• A hearth extending at least 225mm in front of the fire (D), without
obstructions to prevent the door opening
(The fireplace will become VERY hot - Where thin slabs of mineral
material (marble, limestone etc) are used to face a fireplace, we
recommend using 5 separate panels, as shown, to allow for
differential expansion.)
The Inset will fit directly into any correctly constructed fireplace
with the fireback (E) broken up and removed, so that a clear, level
depth of at least 260mm is available.
The stove must be firmly fixed in place through the fixing hole(s)
(G) BOTH in the base AND against the face of the fireplace.
Screws are provided for use in sound masonry, but, depending on
the substrate, other fixings may need to be substituted.
This stove is double-cased - it is not necessary to fill any small gap
behind the appliance – larger gaps should be filled with rubble,
vermiculite granules or mineral fibre wool.
It is highly advisable, where fitted into a masonry flue, to form a
smooth mortar flaunching between the flue outlet and the flue.
With care, this can be done through the flue outlet.
A soft seal is fixed to the back seating surface of the stove. A thicker seal for rough materials such as stone is available from your
dealer. Pull off top and push stove into the opening. Screw to the masonry of the fireplace at the FOUR points arrowed (two through
the base, two above the fire opening) and proceed with the fix as shown below.
Suitable masonry fireplace.
Opening width (A) 400 to
420mm, height (B) 540 to
560mm. Flat area (C) extending
70mm around the opening, a
hearth extending at least
225mm in front of the fire(D),
without obstructions to prevent
the door opening.
'FIREPLACE SEAL' METHOD:
Fix the four bolts
to hold the stove
in place and,
through the flue
outlet, fill any gap
behind with
vermiculite
granules topped
with mortar.
Carefully check
that the fire has an
absolutely airtight
seal against the
fireplace.
FAST-FIX 'CHIMNEY SEAL' METHOD:
Obtain a PD-Q flue
connector. Fit the flue
pipe, or 150mm flexible
liner, into the chimney
and fasten its loose end
to the PD-Q connector,
sealing well with fire
cement. Fix the four
bolts to hold the stove.
Smear a little fire
cement around the flue
outlet and bolt the
connector and pipe
back in place from
inside. Check that the
pipe forms a clear route
from stove to chimney
terminal with no leaks
into the masonry space.
Whichever method is used it is imperative that: (1) The route for gases from the stove to the chimney terminal is completely air-tight;
even the tiniest gap or crack can spoil the updraught. Seal all joins with fireproof cement and/or heatproof rope. (2) It is possible to
sweep the entire length- access doors may be required. (3) The entire construction is of durable fireproof materials. (4) It is wise to fit a
CO alarm.
