Valor COSYFLAME TURBOCHIM 528 Installer's Manual page 5

Installation to a timber framed building should be in accordance with the relevant
sections of Institute of Gas Engineers publication IGE/UP/7 "Gas installations in
timber frame buildings". Please note that advice should be sought before installing in a
timber frame building since the alterations required may nullify any NHBC cover relating
to the property. If in doubt, guidance should be requested from your local authority
planning or building department.
This appliance must be mounted with a non-combustible hearth (N.B. conglomerate
marble hearths are considered as non-combustible). The fire box must be mounted on a
non-combustible surface level with the hearth. The hearth must project at least 345mm
forward of the fire box front and be at least 625mm wide (see illustrations in "wall
preparation" section). The hearth material must be at least 12mm thick. The periphery
of the hearth (or fender) should be at least 50mm above floor level to discourage the
placing of carpets or rugs over it.
The surface of the hearth must be sufficiently flat to enable the bottom of the front
casting to be aligned horizontally. Any excessive unevenness (uneven tiles, Cotswold
stone, etc.) should be rectified.
The appliance must not stand on combustible materials or carpets.
The appliance must not be fitted directly against a combustible wall. If the
appliance is to be fitted against a wall with combustible cladding or skirting board, such
materials must be removed from the area covered by the metal outer surround of the
appliance. We suggest that the actual surround is used as a template to mark the area for
combustible cladding removal.
The appliance can be fitted to
a purpose made proprietary
class "O" 150°C surround.
The opening in the surround
or wall recess for the fire box
must be within the limits
shown in figure 1.
The front face of the wall
should be reasonably flat over
the area which will be covered
by the fire box top and side
flanges to ensure a good seal.
The minimum height from
the top surface of the hearth to
the underside of any shelf
made from wood or other
combustible materials is as
follows:-
• For a shelf up to 150mm
deep
Minimum height = 750mm.
• For a shelf deeper than 150mm
Minimum height = 750mm + 12.5mm for every 25mm depth over 150mm.
Note that soft wall coverings (e.g. embossed vinyl, etc.) are easily affected by heat. They
may scorch or become discoloured when close to a heating appliance. Please bear this
in mind when installing.
The appliance must not be installed in any room which contains a bath or shower or
where steam is regularly present.
An extractor fan may only be used in the same room as this appliance, or in any area
from which ventilation for the appliance is taken, if it does not affect the safe
performance of the appliance. Note the spillage test requirements detailed further on in
this manual. If the fan is likely to affect the appliance, the appliance must not be
installed unless the fan is permanently disconnected, or provision is made to ensure that
the fan and the appliance cannot be used at the same time.
