Using 3 Tappings Page 9 LA30iB 3.99 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. 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 fire to protect it. Ensure that the flue pipe is central and then fill the space between the body of the fire and the structural brickwork with vermiculite (eg. 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. Make good the holes in the front and side of the chimney breast making sure that they are completely airtight. A typical installation is shown in Fig. 10. 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 in-filling. 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. 11. 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, hood and top grid onto the appliance. Instructions for this are enclosed with the panel pack. Replace any internal parts previously removed. PRE LIGHTING CHECK Before initial lighting check the following points: 1. The bottom grate bars must all be fitted and should move freely and easily when the riddling mechanism is operated. 2. The plates round the sides and 150° Vermiculite Infill Flaunching Take Flue Pipe Up To Narrowest Part Of Chimney. Part No. 010/AV12 150° Elbow Fig. 10. Typical Installation back of the grate must be in position and sitting correctly. 3. The throat plate must be fitted in the roof of the appliance. 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. The central heating pump should be adjusted to give the correct water flow against the circuit resistance and the system should be correctly balanced. On completion of the installation and commissioning please leave the operating instructions with the customer and advise on the use of the fire and any controls on the system.
