A flue draught from 1.2mm to 2.5mm water gauge is required to keep the appliance
operating efficiently. If the flue draught exceeds 2.5mm, a draught stabilizer must be
installed in order to control the rate of burning and prevent overfire. You should check the
flue draught when fire is on high output.
Chimney Connection
You should brick up or seal an existing fireplace opening with a register plate. A short
length of flue pipe of a minimum 125mm internal diameter may then be used to connect
the stove to the chimney. This flue pipe should be of 316 grade stainless steel or vitreous
enameled, nominal thickness 1.2mm. Ensure that the pipe end is no closer than 76mm to
the side or rear chimney walls.
Ideally, the old fireplace should be (BACK??) filled in so that there is a smooth streamline
entry into the flueway.
The length of any horizontal run of flue pipe must not exceed 125mm.
It is essential that all connections between the stove and chimney-flue are sealed and
made airtight.
Both the chimney and flue pipe must be accessible for cleaning and if any parts of the
chimney cannot be reached through the stove(with baffle removed), a soot door must be
fitted in a suitable position to enable this to be actioned.
Air Supply
A permanent, unobstructed air opening is essential for the room or space containing this
appliance. The air opening should be at least 3625mm
2
when a draught stabilizer is
equipped. Air requirements must be carefully considered when using other appliances
within the same room.
Safety Clearances
It is acceptable for the appliance to be recessed in a prepared fireplace, but a suitable free
air gap (minimum 150mm) must be left around the sides and top and at least 50mm at the
back of the appliance to reach maximum heat output and for access to the rear of the
stove. All non-combustible walls closer than 300mm to the stove should be at least 75mm
thick.
In all circumstances the back wall of the fireplace recess and the hearth should be made
of non-combustible material,
Allow an apron of a least 300mm at the front of the stove and 150mm on either side.
The hearth on which the stove is to be placed should not be less than 125mm thick and
should be in accordance with the current building regulations.
Care should be taken to level the stove.
The appliance shall be installed on floors with an adequate load-bearing capacity. If an
existing construction doesn
’t meet this prerequisite, suitable measure (e.g. load
distributing plate) should be taken to achieve it.
There should be no combustible material within a distance of 500mm from any surface of
the stove.
