Installation
Building regulations
Installation of the 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
Fixed ventilation is not required for this stove as it has an output of less than 5kW, but there must be
adequate supply of fresh air to the room in which the stove is to be installed.
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 50KG.
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.
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 stove has top flue connection only. Position the stove and seal the flue connections with fire cement or
a high temperature rope seal. Figure 3 shows a typical installation for which you would need:
• A register plate. - This is the plate used to seal off the throat of the fireplace and has a
hole for the flue pipe, access for sweeping and, if required, a bracket to support the flue
pipe.
• The 5” flue pipe needed to go from the stove to the register plate.
