the new appliance.
Refer to figure 24.
• The appliance wall mounting template shows the relative positions of
the flue and the top and bottom fixings of the wall mounting frame.
1. Fix the wall mounting template to the wall in the desired position.
2. Drill the four holes indicated on the wall template for the wall
mounting frame through the template.
The wall mounting template has been sized to allow for
minimum clearances of 5mm sides, 200mm base and
170mm above appliance case (which is 30mm above a
100mm diameter flue elbow).

which the flue will pass through [4].
▶ Allow for a rise of 52mm per metre length of flue, to give a 3° angle.
