Flue hole cutting
• Mark the position of the flue centre.
• Remove the wall template, then drilling the flue hole.
i The flue is designed with an internal fall of 44mm/
metre (2.5 o ), therefore the hole can be drilled
horizontally.
• Use a 105mm diameter core drill for external access flue
installation (60/100 flue) (80/125 flue ► Ø130mm).
• Use a 125mm diameter core drill for internal access only flue
installation (60/100 flue) (80/125 flue ► Ø150mm).
i
If flue extension pipes are to be used then a core
drill size of 125mm is required. This will allow the
extension pieces to slope at 44mm/metre (2.5 o )
towards the boiler.
• If fitting a side flue, extend the flue centre line into the corner
then 130mm along the adjacent wall.
• If fitting an extended side flue, determine the flue hole centre
by extending the dashed inclined line on the template to the
side wall. This dashed line is drawn at 44mm/metre (2.5 o )
rise from the boiler. Where this line reaches the side wall, a
horizontal line should be marked. The vertical centre line of
the flue should then be marked at 130mm from the back wall.
To allow for the flue passing through the wall at this angle
a 125mm hole should be drilled irrespective of internal or
external installation.
Hanging bracket fixing
Due to the varied site conditions, fixings are not supplied and
advise that the installer should supply those which are suitable.
• Drill the holes for the fixing screws in accordance with the
wall template.
• Fix the hanging bracket on the wall.
