accordance with the current edition of the Gas Safety (Installation and Use) Regulations. Failure to install the appliance
correctly could lead to prosecution. The Council for the Registration of Gas Installers (CORGI) requires its members to
work to recognised standards.

A minimum clearance of 140mm should be maintained at the right side of the fire to allow easy access to the
control knob and 75mm at the left side to allow access to the knurled nut for removal of the outer case.
2.6
Any combustible side wall must be at least 500mm clear from direct exposure to the radiant surface of the
appliance unless suitably protected.
2.7
A shelf or other projection made of wood or any other combustible material may be fitted over the appliance
provided that the following conditions are satisfied:-
Where not more than 150mm deep, there must be at least 150mm clearance above the extreme top surface of the fire. For
greater depth there must be an additional clearance of 12.5mm for each extra 25mm of added projection.
2.8
There is no restriction on the depth of non-combustible projections but a space of at least 30mm should be
allowed above the top of the appliance to enable removal of the case front.
2.9
It is advisable that combustible fabrics such as curtains are not fitted above the fire. If, however, this is
unavoidable, a clearance of at least 150mm must be maintained from the extreme bottom edge of the fabric to the extreme
top surface of the fire.

The appliance can be installed with or without a non-combustible hearth. If a non-combustible hearth is installed,
there must be a minimum clearance from the top surface of the hearth to the absolute bottom of the appliance of 18mm
(see figure 1). The hearth must be at least 700mm wide x 300mm deep. The non-combustible hearth material must be at
least 12mm thick. Its top surface should be preferably 50mm above floor level to discourage the placing of carpets or rugs
over it.
If the appliance is not installed with a hearth meeting the above conditions, the minimum distance from the top surface of
the finished floor covering (including any carpet etc.) to the absolute bottom of the appliance must be at least 40mm (see
figure 1).
