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. 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 concrete 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.

The free inset method of installation may be used instead of infilling. Details are available on request.

THERMOSTAT

Before lighting the fire check the cold setting distance of the thermostat.

With the control knob at the maximum setting the flap should be 18 mm from the air inlet as shown in Fig. 8. To adjust the distance slacken the locking nut and adjust as necessary. When set correctly re-tighten the locking nut. Ensure that the flap opens and closes freely as the knob is turned.

ASSEMBLY

Fit the side panels and hood onto the appliance. Instructions for this are enclosed with the panel pack.

Replace any internal parts previously removed.

COMMISSIONING

On completion of the installation and after allowing a suitable period of time for the fire cement and mortar to dry out, the fire should be lit and checked to ensure that smoke and fumes are taken from the appliance up the chimney and emitted safely. Also check all joints and seals.

On completion of the installation and commissioning please leave the operating instructions with the customer and advise on the use of the appliance.
