HEALTH AND SAFETY PRECAUTIONS
SPECIFICATION
CHIMNEY
Please take care when installing the stove that the requirements of
the Health and Safety at Work Act 1974 are met.
Some types of fire cement are caustic and should not be allowed to
come into contact with the skin. In case of contact, wash with plenty
of water.
If there is a possibility of disturbing any asbestos in the course of
installation then please use appropriate protective equipment.
There must not be an extractor fan fitted in the same room as the
stove as this can cause the appliance to emit fumes into the room.
As the output is below 5kW a permanent air supply is not normally
required. This stove is capable of intermittent operation.
This stove is not suitable for use in a shared flue system.
In addition to these instructions the requirements of BS 8303 and
BSEN 15287-1:2007 must be fulfilled. Local Authority Bylaws and
Building Regulations, including those referring to national and
European Standards, regarding the installation of Solid Fuel burning
appliances, flues and chimneys must also be observed.
Building regulations require that whenever a new or replacement
fixed solid fuel or wood/biomass appliance is installed in a dwelling a
carbon monoxide alarm must be fitted in the same room as the
appliance. Further guidance on the installation of the carbon
monoxide alarm is available in BS EN 50292:2002 and from the
alarm manufacturer's instructions. Provision of an alarm must not be
considered a substitute for either installing the appliance correctly or
ensuring regular servicing and maintenance of the appliance and
chimney system.
The nominal output of the C-FOUR is 4.9 kW (16,700 Btu/h). This
output is based on a 45minute re-fuelling cycle burning seasoned
hardwood logs. The average flue temperature at rated output is
281°C. The Flue gas mass flow is 4.2g/s and the stove weight is
62kg.
In order for the appliance to perform satisfactorily the chimney height
must not be less than 4 metres measured vertically from the outlet of
CO ALARMS
the stove to the top of the chimney. The internal dimensions of the
chimney should preferably be 175 mm (7 inches) or 200mm (8
inches) either square or round and MUST NOT BE LESS THAN 125
mm (5 INCHES).
If an existing chimney is to be used it must be swept and checked, it
must be in good condition, free from cracks and blockages, and
should not have an excessive cross sectional area. If you find that the
chimney is in poor condition then expert advice should be sought
regarding the necessity of having the chimney lined. If it is found
necessary to line the chimney then a lining suitable for Solid Fuel must
be used.
If there is no existing chimney then a prefabricated block chimney or
a twin walled insulated stainless steel flue to BSEN 15287-1:2007 can
be used either internally or externally. These chimneys must be fitted
in accordance with the manufacturers instructions and Building
Regulations.
Single wall flue pipe is suitable for connecting the stove to the
chimney but is not suitable for using for the complete chimney.
If it is found that there is excessive draw in the chimney then a
draught stabiliser should be fitted.
It is important that there is sufficient draw in the chimney and that
the chimney does not suffer from down-draught. When the chimney
is warm the draw should be not less than 2.5mm (0.10 inches) water
gauge (25 Pa). If in doubt about the chimney seek expert advice.
HEARTH AND FIRE SURROUND
The stove must stand on a fireproof hearth and must not be situated
closer than 600mm from combustible materials to the sides or rear
above hearth level unless adequately fireproofed in accordance with
local building regulations. The hearth must be of fireproof material
and at least 12mm (½ inch) thick. The positioning of the stove and
the size of the hearth are governed by building regulations for Class 1
appliances. These building regulations state that the hearth must
extend in front of the stove by at least 300mm (12 inches) and to the
sides of the stove by at least 150mm (6 inches).
If in
doubt as to the positioning of the stove, expert advice should be
sought either from the supplier or the local building inspector.
The fireplace must allow good circulation of air around the appliance
to ensure that maximum heat is transferred to the room and also to
prevent the fireplace from overheating. A gap of 150mm (6 inches)
each side and 300mm (12 inches) above the appliance should give
When the fire door
is open, it extends beyond the flat front of the stove by 365mm.
