6 Installation Preparation
6.1 Appliance Pack
Please check the contents of packs as shown in diagram 6.1.
The packs are located in the top polystyrene packing.
Remove the carton sleeve and top pack then lift the boiler and
its polystyrene base support out of the lower pack.
6.2 Site Requirements
The boiler mounting wall should be suitable for the weight of the
appliance and be true and fl at.
NOTE: Due to the varied site conditions we do not supply
fi xings and advise that the installer should supply those which
are suitable.
6.3 Wall Template
Take the wall template from the document pack located within
the top polystyrene packing and place in the desired position
on the wall, giving due consideration to the required boiler
clearances, see section 3 , and the fl ue you are fi tting.
Mark the position of the fl ue centre, if fi tting a side fl ue, extend
the fl ue centre line into the corner then 149mm along the
adjacent wall, see diagram 6.2.
For extended side fl ues, the fl ue hole centre should be
determined by extending the dashed inclined line on the
template to the side wall, then 149mm along the adjacent wall,
see diagram 6.2. This dashed line is drawn at 44mm/metre
(2.5°) rise from the boiler.
To allow for the fl ue 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 fl ue hole.
6.4 Flue Hole Cutting
External access fl ue installation can use a 105mm diameter
core drill.
Internal access only fl ue installation will need a 125mm
diameter core drill.
NOTE: The fl ue is designed with an internal fall of 44mm/metre
(2.5°), therefore the hole can be drilled horizontally.
If fl ue 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°) towards the boiler.
