Installation
Building regulations
Installation of this Firebelly woodburning stove must comply with all local building regulations, including those
referring to national and European standards. It is a good idea to consult your local chimney sweep to check the
suitability of the chinmney and ensure there is adequate updraft and suggest any remedies to potential chimney
problems. Document J of the Building Regulations contains further information regarding the installation of solid
fuel appliances and can be viewed here : www.odpm.gov.uk or follow the link on the Firebelly website.
Ventilation
There must be a constant supply of fresh air to the room in which the stove is to be installed. Fixed ventilation must
be provided when installing any solid fuel stove which has an output higher than 5kws. For each kilowatt above
five, 550 sq mm (2.56 sq ins) of ventilation is required. This stove has a maximum output of 10kws and so there
should be fixed ventillation of a minimum
2750 sq mm.
Any airbricks or grilles fitted for this purpose should be
positioned so that they are not liable to blockage. If other appliances requiring ventilation operate in the vicinity of
the stove then there must be adequate ventilation to provide for both appliances operating simultaneously.
NOTE Extractor fans when operating in the same room or space as the stove, may cause problems.
Load-bearing capacity of the floor
Before installing the stove, you must ensure that the load-bearing capacity of the floor can withstand the weight of
the stove and any flue pipe and connections. The weight of the stove is
80KG.
Hearth
The stove should always be installed on a non-combustible hearth. The hearth should extend to a distance of
225mm in front of the stove and 150 mm to each side measured from the door of the combustion chamber. See
document J of the building regulations for more information on hearth requirements.
Clearances
The minimum distance to combustible materials should be 500mm at the back of the stove and 150mm to the sides
of the stove. Adjacent walls should be of suitable non-combustible construction, preferably brickwork. Make sure
that there is a gap between an uninsulated flue pipe and any combustible material. This gap must be at least 3 x the
outside diameter of the flue pipe (375mm for 5” single wall flue pipe), or 1.5 x the flue diameter (375mm for 5” single
wall flue pipe) to non combustible surface. A minimum clearance of 80mm around the sides and back of the stove is
recommended to allow for air movement and heat from the stove to enter the room.
Chimney requirements
An existing chimney or a new flue or chimney installation should be given a visual inspection to check that it is in
good order, clear of obstructions and is of a suitable size and type for the stove. It may be necessary to sweep the
flue (which should always be done anyway before fitting a stove or lining a chimney) and also, if necessary, to do a
smoke test to check for gas tightness and chimney draft. The chimney or flue must not serve any other appliance.
For nominal heat ouput:
The minimum flue draught required is 12PA.
The flue gas temperature directly down of the socket will be approximately 262 deg C.
Air damper
It is recommended that chimneys with a strong updraft be fitted with a flue pipe damper or draft stabiliser so that
the chimney draught can be regulated. It is not allowed that any damper close the pipe totally. There must always
be a free area of min. 20% of the total opening of the chimney or the pipe.
Flue connection
The stoves has both rear and top flue connection. The flue blanking plate should be positioned over which ever
outlet is not being used, position the blanking plate over the outlet and use the access via the the opposite flue
outlet to fix the clamp to the back of it, see
Figure 4
. Position the stove and seal the flue connections with fire
cement or a high temperature rope seal.
