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 sufficient air
circulation. If a wooden mantelpiece or
beam is used in the fireplace it should be
a minimum of 460mm (18 inches), and
preferably 600mm (24 inches) from the
appliance. In some situations it may be
necessary to shield the beam or
mantelpiece to protect it.
HOT WATER SYSTEM
The optional add-in boiler which may be
fitted in the appliance has an output
sufficient for domestic hot water heating.
If the boiler is fitted then the room
heating will be reduced.
The hot water system should be a gravity
circuit and must be correctly vented as
shown in Fig. 3.
A double feed indirect hot water storage
cylinder to BS:1566 part 1 should be used
in most situations, unless the appliance is
to be fitted in a soft water area in which
case a direct hot water cylinder may be
used provided that the boiler is glass
lined.
All pipework in the primary circuit must
be 28mm diameter and the flow pipe
must rise continuously from the boiler to
the open vent.
If an indirect cylinder is used then the
primary circuit should be filled with a
suitable inhibitor to prevent the build up
of scale and corrosion.
HEALTH AND SAFETY
PRECAUTIONS
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.
There must be an adequate air supply
into the room in which the appliance is
installed totalling at least 100 square cm.
(16 square inches) to provide combustion
air. This is particularly necessary if the
room is double glazed.
In addition to these instructions the
requirements of BS.8303 and BS.6461 Pt
1&2; 1984 must be fulfilled. Local
Authority Bylaws and Building
Regulations regarding the installation of
Solid Fuel burning appliances, flues and
chimneys must also be observed.
PERFORMANCE
The output of the Country 8 WB is 8.0
kW (27,300 Btu/h). The output of the
Country 12 WB is 12.0 kW (40,900
Btu/hr). The optional add-in boiler has an
output of 2.9 kW (10,000 Btu/h), if the
boiler is fitted then the heat output to the
room will be reduced by this amount.
These outputs are based on a 2 hourly
re-fuelling cycle burning seasoned
hardwood logs, or a 4 hourly re-fuelling
cycle burning coal or smokeless fuel.
CHIMNEY
In order for the appliance to perform
satisfactorily the chimney height must not
be less than 4 metres measured vertically
from the outlet of 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 150 mm (6 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
BS.4543 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 stabilizer
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. If in doubt about the chimney seek
expert advice.
HEARTH AND FIRE
SURROUND
The stove must stand on a fireproof
hearth and must be situated at least
300mm (12 inches) from any combustible
material. There must be a gap behind the
stove of at least 25mm to allow air to
enter the airwash inlets. The positioning
of the stove and the size of the hearth are
governed by building regulations for
Class 1 appliances. These building
