This appliance becomes extremely hot and can produce poisonous gases. A fire guard should be used if children or the infirm are present. The installer is required
to exactly follow these instructions and to completely comply with all relevant local, national and international standards.
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 asbestos in an old installation.
Weight: Your stove is heavy – take great care when moving it and ensure that the intended fireplace can support the weight – consider fitting a load distributing plate.
Your Chimney
Once warm, your chimney makes the gas inside it rise, pulling fresh air into the stove to make it work. Your chimney must:
Generate a draught in use of at least 12 Pa (0.05ins wg) and not in excess of 25 Pa.
Be capable of withstanding the temperatures generated.
Be absolutely incapable of leaking fumes into the dwelling – this will commonly be achieved by it:
Being at least 5m high.
Terminating at least 1m above any roof ridge.
Having an internal cross-section not less than 0.018m² (e.g.: 150mm dia) and never more than 0.14m² (e.g.: 375 x 375mm).
Being free from even the slightest crack or source of leakage.
Having no bends sharper than 45°.
Being entirely free of obstructions and swept by a qualified chimney sweep.
Being connected to only this stove.
Being of thick masonry or otherwise adequately 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 for cleaning 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 become very hot - take great care in siting vulnerable materials like
wax, textiles, paper etc.
Air Supply
Your stove needs air to breathe – there must be a permanent fresh air supply into the space in which it is installed equal to the size given on page 1. This can often be
provided by air leaking around door frames etc. (it is commonly accepted that this alone may suffice for appliances <c5kW) but in case of any doubt, fit a purpose made
air vent. An extractor fan, or another fuel using appliance in the same building, can remove this air.
Fit a Carbon Monoxide alarm near to the stove.
Fitting
Fasten the flue outlet and blanking plate to the top or back flue outlet opening, on a thin bead of fire cement. Do not over tighten.
Place the stove on a non-combustible hearth conforming to building regulations, noting the distances to combustible materials given in
the table on the front of this document.
Fix the stove securely to the hearth by drilling through the fixing holes inside the stove, into the hearth, with a 6mm masonry drill. Screw
down with the bolts and washers provided. If you chose to secure the stove using an alternative method you should seal the two holes in
the base of the stove to prevent air being drawn in when the bottom valve is closed.
Your stove can be sealed to the chimney using a short (up to about 500mm) length of uninsulated pipe in several ways, four of which are
shown below.
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.
Check the Installation
Once installed, light the fire, demonstrate it to the householder and check that:
1)
It burns controllably and does not emit fumes to the room.
2)
The route for gases from the stove to the chimney terminal is
completely airtight, unobstructed and able to be swept.
3)
The entire construction is of durable fireproof materials.
4)
The flue presents a draught in use of at least 12Pa and not in excess of
25 Pa.
