The fireplace opening should be inspected and repairs made where necessary. Any chair brick or fireback may be left in situ, providing that
the dimensional requirements for debris collection space and spigot clearances are met. See diagram below..
The opening WIDTH and HEIGHT dimensions should be between 375mm and 450mm wide, and 540mm (see note below) to 575mm high.
Note: The spigot outlet of the fire is 560mm high, but should fit into the gather at the top of the fireplace as the appliance is fitted. Any mod-
ifications to the fireplace opening must be to a height of 560mm min.
Opening DEPTH should be 200mm or greater for a clay/cement lined or pre-cast flue which is new, unused, or previously used only with a
gas appliance. DEPTH should be 240mm or greater for a flue used for solid fuel of oil burning appliances. Opening DEPTHS include any plas-
ter or infill panels which form part of the installation.
This appliance requires a natural draught flue system which may be one of the following;
225mm x 225mm (9in x 9in) brick or stone.
125mm (5in) minimum diameter lined brick or stone.
125mm (5in) minimum diameter twin wall flue conforming to BS 715.
Pre-cast block flue complying with BS 1289.
Any existing under grate draught device must be sealed off. The opening wall must be non-combustible.
The appliance requires a hearth with non-combustible surface of at least 12mm thick. The top surface must be at least 50mm above the sur-
rounding floor level, or be surrounded by a raised edge or fender 50mm high.
To enable the products of combustion to be cleared properly up the flue, the outlet at the back of the appliance must have a 50mm mini-
mum clearance between it and the back wall of the opening or any other obstruction. The area immediately above the outlet must form a
smooth path into the flue.
Any type of fire surround used with this appliance must be adequately sealed to the wall and floor.
A combustible shelf may be fixed to the wall above the fire, providing that it complies with the dimensions given below.
A non-combustible shelf may be fitted to within 10mm of the top edge of the fireframe. Combustible materials, such as wood, may be fitted
to within 100mm (4in) of either side of the fireplace opening, providing the forward projection does not exceed 100mm (4in).
Any combustible side walls must be at least 500mm to the side of the radiant heat source.
As with all heating appliances, any decorations, soft furnishings, and wall coverings (i.e. flock, blown vinyl and embossed paper) positioned
too close to the appliance may discolour or scorch.
B. Opening width: 375mm min/450mm max.
C. Mounting depth: 180mm
D. Hearth must extend minimum of 150mm either
side of the opening.
E. Hearth must extend minimum of 300mm in
front of the opening.
F. Non-combustible hearth must be a minimum of
50mm in height, or be surrounded by 50mm high
ensure a good seal.
H. 585mm, this area must be flat and vertical to

The mounting depth of this appliance is 180mm.
In accordance with BS 5871 part 2, minimum debris collection volumes are required behind the installed appliance. These are shown in the
table below and as dimension X on the fireplace diagram shown previously.

No purpose provided ventilation is normally required for this appliance. The requirements of other appliances operating in the same room or
space must be taken into consideration when assessing ventilation.
If spillage is detected when commissioning the appliance, then amongst other problems there may be insufficient natural ventilation for cor-
rect operation of the flue. If the appliance does not spill with the windows open, but spillage is detected with the windows closed, this demon-
strates a lack of natural ventilation. If spillage is still detected with the windows open, the flue is at fault. Installation of an air brick is the best
solution to lack of ventilation. Any ventilation fitted must comply with BS 5871 part 2 and BS 5440 part 2. Vents fitted under or within the
immediate vicinity of the appliance must not be used as adverse effects to the operation of the ODS may occur.
Spillage detected during commissioning is almost always a result of poor flue performance that cannot be corrected by any amount of venti-
PREFABRICATED FLUE BOXES
This appliance can be fitted into a number of proprietary flue boxes provided that the minimum dimensions given in the diagram below are
Constructional Note: The frame of the fire, any back panel or
other infill panels, and the flue box must be sealed together
so that there is no possibility of leakage between them.
Adequate clearances to combustible materials (e.g. false
chimney breast construction) must be maintained.
The manufacturers’ instructions for fitting the prefabricated
box shall be complied with at all times.
To fit the fire using the cable fixing kit, some minor adaption
may be necessary for certain flue boxes. A check should be
made to ensure the firebox does not obscure the flue box
The firebox, base of the flue box, and hearth below may be
It is important that the sealing requirements of the appliance
are met at all times and that the flue box is well sealed to any
back or infill panel.
Note: The DEPTH dimension is inclusive of any back or infill
Stand the carton the right way up, cut the strapping bands and remove the top endcap. Read
all the instructions before continuing to unpack
or install this appliance.
Remove the boxes containing the firefront and the ceramic components. Remove the cardboard packing pieces, and any other bags or boxes
containing fittings or other parts. When all loose parts have been removed, the outer sleeve may be lifted off to reveal the appliance. Check
