cylinder to BS:1566 part 1 should be used in most situations, unless the appliance is to be fitted in a soft water area in which case the stainless steel boiler may be used with a direct hot water cylinder.

All pipework in the primary circuit must be 28mm diameter and the flow pipe must rise continuously from the boiler to the open vent.

If an indirect cylinder is used then the primary circuit should be filled with a suitable inhibitor to prevent the build up of scale and corrosion.

FITTING THE

OPTIONAL ADD-IN

BOILER

The boiler replaces the rear firebrick and is reversible so that the 1’’ B.S.P. male tappings may come on either the left or the right hand side of the boiler.

The boiler tappings protrude from the sides of the appliance and it will therefore be necessary to fit the boiler into the appliance after positioning the appliance in the fireplace if the fire surround is already fitted.

Before fitting the boiler, remove the front firebars, the side and back fire

plates and the firebricks. Knock out the knock-outs for the boiler tappings on the appropriate side of the firebox.

Remove the backnuts and fibre washers from the boiler tappings and fit the boiler into the appliance. Place the fibre washers over the tappings on the outside of the appliance and fit the backnuts, ensuring that the boiler is held tightly against the rear inside face of the appliance and that the top edge of the boiler is level or runs uphill to the flow tapping.

When re-fitting the firebricks, note that the short side firebrick supplied with the boiler must be fitted on the same side as the boiler tappings. One of the original side firebricks is fitted on the other side, and the rear firebrick is discarded. The firebricks must be fire cemented into position, wetting the firebox will improve the adhesion.

Replace the back fireplate, the side fireplates, the front firebar and the throat plate.

Connect the boiler to the heating system ensuring that the flow pipe rises from the boiler. Fill the system with water and check for leaks.
