3.01 Drilling Template (Top Flue Application)

Select suitable mounting position for boiler, using the template mark fl ue outlet and boiler mounting points.
Drill two 10mm holes 70mm deep to accept the wall plugs. Fit standard wall plugs on the left and right side and
the special wall plug in the middle (fi g. 13a). Fix the wall bracket to the wall using standard lock nut (M8) on both
sides. Mount the boiler on the wall bracket and fi x using the special antitheft nut (M8) as described in the fi g. 13a.
Using a core drill cut a 118mm diameter hole for the fl ue
