INSTALLATION INSTRUCTIONS FOR THE
CHARNWOOD COUNTRY 14B
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.
Do not light the fire before the boiler has been connected to the system and filled with water, as this can cause serious damage to the boiler.
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 14B is 10.5 kW (35,800 Btu/h) to water and 3.7 kW (12,600 Btu/h) to the room. The outputs were obtained burning smokeless fuel over a four hourly re- fuelling cycle with the doors closed.
The heat output to the room is directly proportional to the heat output to water as shown in Fig. 4. This means that if the water heating load is less than the rated output then the room heating will be reduced by the same proportion. This must be borne in mind when calculating the heating requirements.
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 (e.g. greater than 250mm x 250mm). 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 2.54
mm(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. 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 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.
CENTRAL HEATING
SYSTEM
The central heating system must comply with BS:5449 part 1.
If the system is to be a combined heating and domestic hot water system then a double feed indirect hot water storage cylinder to BS:1556 part 1
