8.0 REBATED SURROUND INSTALLATION
NOTE: The following instructions relate to walls where it is not feasible to cut an opening into the wall. The installation will
require a 152 mm rebated surround. If the wall is wholly or partly of combustible material then the combustible wall kit
ÿ
Part No. 994530 must be used (see Combustible Wall Installation Section 9.0). Check the wall thickness. The following
lengths of flue, up to 658 mm, are available and must be ordered specifically.
ÿ
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
993239
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).
All other relevant installation requirements apply (see Section 2.0 Installation Requirements.)
8.1 Position the template supplied on the face of the wall ensuring that its top is level and that the centre line of the flue is
351 mm above the hearth level. Mark the four fixing bracket positions (see Fig 4.).
8.2 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
wall at both ends of the hole.
8.3 Drill the four fixing holes to a minimum depth of 57 mm using 6 mm diameter masonry drill and insert the plugs.
8.4 Screw the four fixing brackets supplied to the wall ensuring that they are positioned with the return flange pointing
outwards.
8.5 Remove the outer case from the heater by lifting it up and away from the locating hooks.
8.6 Place the heater face down taking care to protect any soft surface.
8.7 Fit the flue and air ducts to the back of the heater using the gaskets and screws provided. This operation is made
easier by using the screws to tap the holes before assembly. The four screws for the flue duct are already fitted to the
heater. The flanges of the ducts are marked ‘TOP’ to indicate the way in which the ducts are to be fitted. Note:
DO NOT
remove the two middle slotted screws.
8.8 Adjust the flue length: First measure the wall thickness and add 148 mm to give the overall length of flue ‘A’ (see Fig
6A.) Fit the terminal assembly to the ducts already fitted to the heater. The top of the assembly is marked ‘TOP’. Set
the overall length of the flue to the dimension ‘A’. Drill 2.7 mm diameter for the fixing screws and secure it with the
screws provided. Seal the joint using the self-adhesive tape provided.
NOTES:
(i) If rear entry gas supply connection is required, then it
MUST
be installed prior to the installation of the
heater (see Section 11.1 Rear Entry Gas Connection).
(ii) If front entry gas supply connection from the left or right side is required, then it
MUST
be installed after the
installation of the heater (see Section 11.2 Front Entry Gas Connection).
(iii) An suitable means of isolation must be fitted in the gas supply line to the heater.
8.9 If fitting to a non-combustible wall, with a 135 mm diameter hole, then the cavity must be sealed from the room by fitting
the additional foam seal supplied around the flue, approximately 37 mm from the heater connection.
8.9 Remove the tape from the foam sealing strip(s) on the flue. Do not remove the tape before the heater is ready to be
installed as the foam strip commences to expand once the tape is removed. The rate of expansion however, is low and
there will be adequate time to install the heater, after which the foam strip will continue to expand and fill the gap
between the flue and the wall. If for any reason the sealing strip has already expanded before the heater is installed, it
can simply be compressed by hand until it is flush with the surface of the flue.
8.10Insert the flue into the opening in the wall created for the flue. Push the heater back towards the wall until the ‘V’ notch
in the fixing brackets line up with the back panel of the heater. Fix in position with the self tapping screws provided.
8.11 Slide the ‘marble’ into position between the heater fixing brackets and the seal on the back of the heater, taking care
not to damage the seal. check the dimension from the face of the marble to the face of the wall.
8.12 Offer up the 152 mm rebated surround to the wall and fix in position.
