6.3 Wall Template
Take the wall template from the document pack located within
the top polystyrene packing
on the wall, giving due consideration to the required boiler
clearances, see section
Mark the position of the flue centre, if fitting a side flue, extend
the flue centre line into the corner then 176mm along the
adjacent wall, see diagram 6.2.
For extended side flues, the flue hole centre should be
determined by extending the dashed inclined line on the
template to the side wall. This dashed line is drawn at 44mm/
metre (2.5°) 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 156mm 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.
Remove the wall template whilst drilling the flue hole.
