1. Remove the fixing template (Fig. 14c) from the carton.
2. After considering the site requirements (see Section 5.2)
position the template on the wall ensuring it is level both
horizontally and vertically. If it is desired that the appliance is
positioned centrally between two points, mark the wall
accordingly and align the template centreline with this mark.
3. Mark at least four suitable fixing holes for the wall plate.
Preferably the two at either side of the flue airbox should be
used. Drill the anchorage holes 63mm (2½in) deep to accept
suitable wall plugs.
4. Mark the centre of the flue hole (rear exit). For side exit,
mark as shown, If required, mark the position of the gas,
water and pressure relief discharge pipes. Remove the
template.
5. Cut the hole for the flue (minimum diameter 107mm).
