1.3 Important Information

This product contains Refractory Ceramic Fibres (R.C.F.) which are man-made vitreous silicate fibres. Excessive exposure to these materials may cause temporary irritation to eyes, skin and respiratory tract. Care must be taken when handling these articles to ensure the release of dust or fibres is kept to a minimum. To ensure that the release of fibres from these articles is kept to a minimum, during installation and servicing it is recommended that a H.E.P.A. filtered vacuum is used to remove any dust, soot or other debris accumulated in and around the appliance. This should be performed before and after working on the installation. It is recommended that any replaced item(s) are not broken up but sealed within heavy duty polythene bags and clearly labelled “R.C.F. waste”. This is not classified as “hazardous waste” and may be disposed of at a tipping site licensed for the disposal of industrial waste. Protective clothing is not required when handling these articles but it is recommended that gloves are worn and the normal hygiene rules of not smoking, eating or drinking in the work area are followed and always wash hands before eating or drinking.

Notice

Discolouration of wall surfaces

Most heating appliances generate warm air convection currents and

transfer heat to any wall surface against which they are situated.

Some soft furnishings (such as blown vinyl wallpapers) may not be

suitable for use where they are subject to temperatures above normal

room levels and the manufacturer's advice should be sought before

using this type of wall covering adjacent to any heating appliance.

The likelihood of wall staining from convected air currents will be

increased in environments where high levels of cigarette smoke or

other contaminants exist.

7.0 Checking for Spillage

7.1 Checking for Spillage

CAUTION - Whilst checking for spillage care

must be taken to avoid touching hot panels.

1. Before checking for spillage the worst likely operating environment for the appliance must be created. To do this, close all doors and windows in the room and operate any ceiling or extractor fans that may be present, on the wall or within other appliances. If any ceiling or extractor fans are present in an adjoining room then these should be operated and the connecting door left open.

2. There are two stages of appliance operation for which spillage must be checked by following "The Spillage Checking Procedure" shown below (7.2).

3. STAGE 1 - Commencing with the appliance Cold, operate the fire on maximum for five minutes and check for spillage. If spillage is evident then the fire is operated for a further 10 minutes and re-checked. If spillage is still evident then the cause should be ascertained and rectified before continuing with commissioning.

4. STAGE 2 - Following a satisfactory result at stage 1, the fire is left on and the boiler is operated (from Cold) for 5 minutes before checking for spillage again. If spillage is evident then the cause should be ascertained and rectified before continuing with commissioning.

5. If the appliance cannot be commissioned then it should be isolated until the problem is resolved.

7.2 The Spillage Checking Procedure

1. A lighted smoke match should be held in a suitable holder 50mm below the lower louvre of the fire and 50mm from either side of the combustion box inner side panel. The majority of smoke should be drawn into the fire (Figs. 22 &

23).

7.3 Possible Causes of Spillage

1. The smoke match may have been positioned incorrectly, resulting in the smoke being picked up by hot convected air currents.

2. The builders opening or flue installation may be unsound.

3. Inadequate ventilation.

4. Down draughts may be present.

5. Flue blockages.
