Make a hole in the font 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.

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 sidebricks is fitted on the other side, and the rear brick is discarded. The firebricks are held in position by the retaining brackets.

HOT WATER SYSTEM

The optional add-in boiler which may be fitted in the appliance has an output sufficient for domestic hot water heating. If the boiler is fitted then the room heating will be reduced.

The hot water system should be a gravity circuit and must be correctly vented as shown in Fig. 4.

A double feed indirect hot water storage 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 a direct hot water cylinder may be used provided that the boiler is stainless steel.

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