TYPICAL INSTALLATION
The ATHENA R.S. can only be mounted on a non-combustible hearth at least 700 mm wide by 300 mm deep with the heater
central. Its top surfaceshould preferably be 50mm above the floorlevel to discourage theplacing of rugs orcarpets over it.
The heater can beinstalled in the innerleaf of a suitableexternal wall, requiring acut-out 646 mm highby 576 mm wide,ensuring
that the wall aboveis properly supported using the appropriate lintel. (seeSection 13.0 Guidance onFitting a Lintel). The heater
can be fitted into a fire surround having a cut-out 646 mmhigh by 576 mm wide. The material ofthe surround must have a 150°C
application i.e. marked withthe suffix ‘150’
If it is not feasible to cut anopening in the wallthen a rebated surroundwith a 152 mmrebate should be used,to enable the heaterto
be fixed to the inner face of the wall. If the wall is constructed from combustible materials, either wholly or partially, then the
combustible wall kit ÿ Part No. 994530 and a 152 mm rebated surround MUST be used. (see Section 8.0 Rebated Surround
Installation and Section 9.0Combustible Wall Installation).
There is a seal onthe back of the heaterwhich seals against the wallto prevent draughts from thecavity into the room.
NOTES :
1. When installing the heaterusing a 152 mmrebated surround, the hearthdepth must be increasedby 152 mm also.
2. When fixing the flue length, the wall thickness must be measured from the inner face of the fire surround (Refer to
Section 10 Preparation ofheater).

6
Note that in England and Wales the Building Regulations require a terminal guard to be fitted if the terminal is less than 2m
(6ft 6in) from the level of any ground, balcony, flat roof or place to which any person has access and which adjoins the wall
in which the outlet is situated. A suitable guard assembly is available from Robinson Willey Limited. The part number is
994371. In Scotland, although the Building Standards (Scotland) do not require a terminal guard to be fitted, the fitting of a
guard as detailed above is recommended.
INSIDE CLEARANCES :
1. Allow 50mm access at each side of the heater for servicing.
2. Curtains must be 150mm clear at the top of the heater and 50mm at the sides and must not be closeable over the front
of the heater.
3. A wooden or combustible shelf may be fitted over the heater. The minimum height of the underside of the shelf of
125mm depth must be 130mm . For shelves of greater depth, allow an additional clearance of 15mm for every 25mm
additional shelf depth.
4. A minimum clearance to combustible material of 500mm is required around the heater.

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.
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).
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.

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.

9.1 For installation on walls constructed or comprising combustible materials, reference should be made to the
requirements of BS 5440 and the Building Regulations.
9.2 Timber Framed Housing: For a timber framed house, the fire can be installed as directed in The Institute of Gas
Engineers Utilization Procedure IGE/UP/7 GAS INSTALLATIONS IN TIMBER FRAME BUILDINGS.
9.3 The combustible wall kit is suitable for walls in which the combustible part is not more than 195 mm thick measured
from the inside of the building.
9.4 The combustible wall kit required is ÿ No. 994530. If the whole of the wall is of combustible material, the outer wall
plate must be used, requiring access to the outside of the building.
9.5 If the screws and the wall plugs supplied are not suitable for a particular application, proprietary cavity wall fixings may
be used.
9.6 Proceed as detailed in Section 8.0 Rebated Surround Installation EXCEPT for the following points: -
(a) Cut the hole for the flue to a diameter of 178 mm through the plaster board taking care not to damage the Vapour
Control Layer (VCL).
(b) Cut the VCL 10 mm less in diameter than the hole just cut in the plasterboard. This will ensure a seal around the
flue liner.
(c) Continue the 178 mm diameter hole through the remainder of the combustible material. If the outer leave of the wall
is constructed of non-combustible material then cut the hole 135 mm diameter making allowances for the shrinkage
†
of the timber frame.
(d) Measure the thickness of the combustible part of the wall and cut the flue liner to this length, cutting off the end
without the fixing brackets. Fit the liner to the sealing plate using the screws provided.
(e) Push the liner through the VCL taking care not to damage the VCL, and ensuring that the liner DOES NOT protrude
into the cavity by more than 10 mm.
(f) If the wall is wholly of combustible material, install the outer wall plate centrally over the hole from the outside as
shown in the diagram below. It is recommended that a silicone sealing compound is applied to the inner face of the
wall plate to provide a watertight installation.
(g) Fit the flue, see Sections 8.7 and 8.8. NOTE: When determining the flue length, measure the wall thickness from
the face of the outer wall plate.
(h) Slide the rope seal over the flue, until it touches the back of the heater, prior to removing the tape from the flue
foam sealing strip.
(I) Before installing the flue into the wall is necessary to provide a moisture barrier around the flue at the point which
will be in the centre of the cavity. Either of the following methods are acceptable: -
(i) Wrap a wire which will not cause corrosion tightly around the flue.
(ii) Form a bead of mastic or silicone around the flue.

‘SHARK’ saw to cut out the correct size of slot required
for the chosen lintel(see Fig 11.).
13.4 Fit the lintel and slate pin, leaving the wall above safe
and firm. Always bed the lintel on mortar, never on a dry
bed (see Fig 12.).
13.5 Remove the masonry below the lintel and clear all the
debris from the cavity. Construct the openingto the size
specified in Section 7.0 Non-Combustible Wall
Installation (see Fig 4.).
A Rockwool™ (or similar seal such as Superlux™ type
board) must be used to prevent the cavity insulation
coming into contact with the hot surfaces of the heater
(see Fig 2.).
Note: the cavity itself must not be bridged by any other
part of the fire other than the flue duct, however the
firebox may encroach into thecavity by up to 40mm.
In all installations ensure that there is no structural
damage to the propertyor to the dampcoarse.
