7.0 NON-COMBUSTIBLE WALL INSTALLATION
NOTE: The following instructions relate to normal brick walls. If the wall is wholly or partly of combustible material, the
heater can not be installed by this method (see Section 9.0.Combustible Wall Installation). Check the wall thickness. Four
different sizes of flue are available for wall thickness up to 658 mm as shown below.

Part number
Mini (telescopic)flue for walls from 280mm to 353mm
990177
Short (requires cutting)flue for walls from 225mm to 353mm
993241
Medium (telescopic) flue for walls from 353mm to 507mm
993240
Long (telescopic) flue for walls from 507mm to 658mm

When fixing the flue length, the wall thickness must be measured from the inner face of the fire surround (Refer to
Section 10 Preparation of heater).
7.1 Create an opening in the wall, in the position required, 646 mm high x 576 mm wide, ensuring that the wall above the
opening is properly supported using the appropriate lintel (see Section 13.0 Guidance on Fitting a Lintel).
7.2 Position the template supplied on the inner face of the outer section of the wall ensuring that its top is level and that the
centre line of the flue is 351 mm above the hearth level.
7.3 Cut the hole for the flue making sure that it is straight and level. This can be done with either a 135 mm diameter core
drill or hammer and chisel. If neatly drilled no making good is necessary. If not it will be necessary to make good the
hole at the terminal end where the flue seal will be located to seal the gap.
7.4 Use the template to mark the cable fixing eyelet positions (see Fig 4.). Drill the four fixing holes to a minimum depth of
57 mm using 6 mm diameter masonry drill and insert the plugs.
7.5 Screw the cable fixing eyelets into the wall plugs ensuring that they are positioned so the cable can run vertically.
