INSTALLATION INSTRUCTIONS FOR THE
CHARNWOOD LA30iB
HEALTH AND SAFETY
PRECAUTIONS
Please take care when installing the appliance 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 fire 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 Byelaws and Building Regulations regarding the installation of Solid Fuel burning appliances, flues and chimneys must also be observed.
PERFORMANCE
The rated output for the LA30iB is
6.1kW (20,800 btu/h) to water and
2.7kW (9,200 btu/h) to the room. These are the outputs obtained during testing in accordance with BS 3378 burning Sunbrite Doubles with the doors closed over a 4 hourly
If the optional boiler reduction brick is fitted and the deepening bar removed then the output is reduced to
3.0kW (10,200 btu/h) to water and
2.1kW (7,100 btu/h) to the room.
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 appliance to the top of the chimney. The chimney should preferably be

175 mm (7 inches) or 200mm (8 inches) internal diameter or square with sides of 175mm or 200mm internally and MUST NOT BE LESS THAN 150mm (6 INCHES) INTERNAL DIAMETER OR 150 x 150mm INTERNAL SQUARE.
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 (eg. 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 fire 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.
HEARTH
The appliance 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 appliance 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 appliance by at least 300 mm (12 inches) and to the sides of the appliance by at least 150 mm (6 inches). If in doubt as to the positioning of the appliance expert advice should be sought either from the supplier or the local building inspector.
PREPARATION OF
FIREPLACE
Before fitting the appliance into an existing fireplace remove the fireback and any loose
The hearth, surround and opening for the appliance must conform with Figs. 5 and 6. The flat area around the opening must be a minimum of 750 mm wide and 660 mm high. Ensure that the hearth and the base in the opening are flat, level, and at right angles to the surround.
Make two holes in the chimney
