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.

FLUE CONNECTION

AND INFILLING

Make the flue connection with the special 150° elbow part no. 010/AV12. Please note that this item is ordered separately from the appliance. a short length of flue pipe. The legs of the elbow may be cut on site to suit the chimney. Also note

that the legs of the elbow are different lengths to enable some situations to be catered for by turning the elbow around.

The end of the flue pipe must line up with the centre-line of the chimney, and must also extend to the point where the chimney narrows to its final size. Any large voids must be filled and flaunched to the flue pipe to ensure that all soot deposits can be cleared when the appliance is swept, and to prevent problems with the operation of the appliance.

Ensure that the flue pipe is not obstructed or restricted in any way and that all joints are well sealed.

Before infilling cover the front of the appliance to protect it. Ensure that the flue pipe is central and then fill the space between the body of the appliance and the structural brickwork with vermiculite (e.g. micafil or similar) concrete. Ensure that there are no air pockets. The

recommended mix is six volumes of vermiculite granules to one volume of portland cement thoroughly mixed together. Enough water should be added so that no more than one or two drops of water are released when a handful of the mixture is squeezed.

After filling with vermiculite flaunch the top of the flue connector pipe to the chimney with lime mortar. Ensure that the flue pipe is well sealed to the chimney.

Make good the hole(s) in the chimney breast making sure that it is completely airtight. A typical installation is shown in Fig. 7.

In most installations it will be possible to sweep the chimney through the appliance. If this is not possible then some alternative means (such as a soot door), must be provided.
