Charnwood FIRECLASS, Operating And Installation Instructions

Page: 8 / 12

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 protec-
tive equipment.
An extractor fan must not be fitted in the same room as
the stove as this can cause fume emission.
In addition to these instructions the requirements of
BS.8303 and BS.6461 Pt 1&2; 1984 must be fulfilled.
Local Authority Byelaws and Building Regulations
regarding the installation of Solid Fuel burning appli-
ances, flues and chimneys must also be observed.
HANDLING
In order to make the stove easier to manoeuvre the door
may be removed. This simply lifts off. Please take care
not to lift the stove by the top enamelled panel as this
will not stand the strain and damage will be caused.
Please also take care not to knock the enamelled items as
this can cause chipping.
PERFORMANCE
The rated output for this appliance is 10.0 kW (34000
btu/h). This is the output obtained burning seasoned
hardwood with a moisture content of less than 20% with
the door closed over a 2 hourly re-fuelling interval. As a
guide this will be sufficient to heat a room of up to
approximately 155 m
3
(5500 ft
3
). If the optional
convection ducts are used to take some of the heat to
other rooms then please remember that this will reduce
the heat to the room in which the stove is situated.
CHIMNEY AND COMBUSTION
AIR SUPPLY
In order for the appliance to perform satisfactorily the
chimney height should not be less than 4 metres
measured vertically from the outlet of the stove to the top
of the flue terminal. The internal dimensions of the
chimney must not be less than 175mm (7 inches)
diameter or 175mm x 175mm square.
Before connecting the stove to an existing chimney 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 the appliance is to be fitted in a room where there is no
existing chimney 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 instruc-
tions 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.
There must be an adequate air supply into the room
totalling at least 10300 mm
2
(16 in
2
) to provide
combustion air.
HEARTH
The stove must be installed on a fireproof hearth and
must be situated at least 300 mm (12 inches) from any
combustible material. 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 300 mm (12 inches) and to the sides
of the stove by at least 150 mm (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.
To allow the door to open the hearth must be flat.
Alternatively the stove may be raised above hearth level.
PREPARATION OF FIREPLACE
Before fitting the stove into an existing fireplace remove
the fireback and any loose in-fill material.
The overall dimensions of the stove are shown in Fig. 1.
The hearth, surround and opening for the appliance must
conform with the dimensions shown in Fig. 2. The flat
area around the opening must be a minimum of 770 mm
wide and 660 mm high. Ensure that the hearth and the
base in the opening are flat and at right angles to the
surround. The base of the opening must be level and
