INSTALLATION INSTRUCTIONS FOR THE

CHARNWOOD LA20i

HEALTH AND SAFETY

PRECAUTIONS

WARNING

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 appliance 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 rated output for the LA20i is 5.4 kW (18800 btu/h) to the room.

This is the output obtained burning Sunbrite Doubles at a rate of 1.0 kg/hr with the doors closed over a 4 hourly re-fuelling interval.

There is an optional add-in domestic hot water boiler available with an output of 2.0 kW (6800 btu/h). If this is fitted then the output to the room will be reduced by a corresponding amount.

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 fire 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 (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 appliance 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 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 in-fill material.

The hearth, surround and opening for the appliance must conform with Figs. 4 and 5. 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 a hole in the front of the chimney breast to give access for infilling and fixing the flue pipe. If the optional boiler is to be fitted it will also be necessary to make a hole in the side of the chimney breast to give access for the pipework.

FITTING THE FIRE

In some cases it may be necessary to place the connecting flue pipe in the chimney before fitting the fire into the fireplace.

Apply fire cement to the rear face of the sealing flange on the appliance. Fit the appliance into the opening ensuring that it is central and that a good seal is made between the sealing flange and the face of the surround.

Remove any excess fire cement from around the sealing flange.

The appliance should be screwed to the hearth through the holes at the base of the sealing flange.
