INSTALLATION
Flue hole cutting
• Mark the position of the flue centre.
• Remove the wall template, then drill 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.

8 Hydraulic connection
8.1 Gas and water connections
The whole of the gas installation, including the meter, should
be inspected, tested for tightness and purged in accordance
with the current issue of BS6891 and in IE the current edition of
I.S.813 “Domestic Gas Installations”.
i The appliance may contain a small amount of water,
place a water container beneath the boiler connections.
• Take care to clean the pipes before assembly removing any
debris or burrs. Grease and oils may need to be removed
they are not possible to remove by cleansing and flushing.
Foreign bodies in the system may enter the appliance and
interrupt its operation.
• Do not use any solvent products, due to the risk of damaging
the circuit.
a
Do not perform any 'hot work' directly under
the appliance, this may cause damage to the
appliance base. Heat may also damage the
isolation valves.
Always pre-solder pipes before fitting them to
the boiler.
