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 flat.
NOTE: Due to the varied site conditions we do not supply
fixings 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 flue you are fitting.
Mark the position of the flue centre, if fitting a side flue, extend
the flue centre line into the corner then 149mm 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 176mm 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.
6.4 Flue Hole Cutting
External access flue installation can use a 105mm diameter
core drill.
Internal access only flue installation will need a 125mm
diameter core drill.
NOTE: The flue is designed with an internal fall of 44mm/metre
(2.5°), therefore the hole can be drilled horizontally.
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°) towards the boiler.
6.5 Wall Hanging Bracket Assembly
The Wall Hanging Bracket is supplied in the main boiler
packaging at the rear of the boiler.
Reposition the wall template over the flue hole and mark the
position of the fixing holes for the hanging bracket, see diagram
6.3.
NOTE: Due to the varied site conditions we do not supply
fixings and advise that the installer should supply those which
are suitable.
Drill fixing holes and insert suitable wall plugs.
Direct Rear Flue only - If external access is not available
the flue to be used should be assembled as described in the
separate flue instructions and inserted through the hole in the
wall before fitting the wall hanging bracket.
Fit the fixing jig support plate to the bottom of the wall hanging
bracket, push down to locate.
Mark, drill and plug at fixing points and secure the jig support
plate, see diagram 6.3.
