21. AIR FOR COMBUSTION

There must always be a permanent means of providing air for combustion into the room in which the fire is installed. A permanent vent with a total free area of at least 5502mm for every kW rated output above 5kw should be connected directly to the outside air or to an adjacent room which itself has a permanent vent of the same size direct to the outside air. The fitting of an extractor fan to either of these rooms is not recommended.

Note: Where a flue draught stabiliser is used the total free area should be increased by 330 sq. mm for each kW of rated output.

22. BUILDERS OPENING/CHIMNEY BREAST

Stratford Si 40 fires are designed to be fitted into a rectangular recess not less than 400mm (15 3/4'') deep, not less than 400mm (15 3/4'') wide and not less than 550mm (21 1/2'') high, the so-called "standard builder's opening".

For Stratford Si 60 fires the minimum depth required is as above but the width of the opening will need to be 610mm (24'') minimum, and the height of the opening will need to be 615mm (24 1/4'').

The fireplace surround should be vertical, and with a flat surface against which the unit can be sealed.

The height and width of the flat surface required will vary according to the model being installed. Where the unit is to be fitted into an existing opening it will normally be necessary to cut a hole through the chimney breast so that a flue connector can be fitted between the appliance and the chimney flue. Avoid damaging the lintel.

For boiler models it may be necessary to cut access holes through the side(s) or the chimney breast, so that flow and return pipes can be connected to the appliance.

23. CHIMNEY

Please remember that chimney draught is dependent on four main factors:

•Flue gas temperature.

•Flue height.

•Flue size.

•Flue terminal.

So keep the flue gas warm by using insulated pipes.

Ensure the flue is long enough - 3.65m (12'') vertical height. Stick to the appliance outlet size, or one size larger.

Terminate away from high trees, higher adjacent buildings, roof ridges, etc., in turbulent air flow (the termination of flues is also subject to criteria set out in the Building Regulations). If possible choose a site with an existing chimney which can be utilised.

Make sure that the manufacturer's recommendations are followed during installation.

Check the chimney is in good repair and free from cracks. When the chimney is warm, a draw of 1 - 2mm water gauge, or 0.1 - 0.2mbar is recommended. If the fire appears to be working hard but produces very little output to the room it is likely that excessive draw is present in the chimney, and that heat is being sucked out of the appliance and up the chimney. If this is the case we recommend the fitting of a flue or flue stabiliser in preference to a flue damper, in the interest of safety and efficiency.

We do not recommend the use of a damper when burning solid fuel.

Core the flue way to remove any blockages, birds nests, etc., and sweep through after any remedial work is completed.

For all appliances.

Access for cleaning the flue should be incorporated in the system other than through the appliance (i.e. a soot door).

For inset fires

If using an insulated steel flue (e.g. Midtherm) ensure that the manufacturer's directions are followed. Take special note that the first 450mm (18'') of the flue should be single skin cast iron or heavy-duty steel flue.
