Site Requirements; Flue Hole Cutting - Glow-worm Ultrapower 100sxi Installation And Servicing

7.1 Loose Items Pack
Please check the contents of loose items pack as shown in
diagram 7.1.
The plumbing jig is located within the tank module polystyrene
top pack.

7.2 Site Requirements

The appliance should be sited on a level floor, however slight
adjustment can be made using the adjustable feet at the base
of the tank module.
The floor strength should be suitable for the combined weight
of appliance and water:
100sxi 175kg
170sxi 225kg
NOTE: Due to the varied site conditions we do not supply
fixings and advise that the installer should supply those which
are suitable.
7.3 Floor Template
Take the floor template from the loose items pack
in the desired position on the floor, giving due consideration to
the required boiler clearances,
you are fitting.
Mark the position of the flue centre, if fitting a side flue, extend
the flue centerline into the corner then along the adjacent wall,
see diagram 7.2.
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 on 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.

7.4 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.
7.5 Plumbing Jig
Align the template with the flue hole then mark the position of
the fixing holes for the jig, see diagram 7.3.
Align the location notches on the jig and secure to the floor
using suitable screws.
