The appliance can be mounted either on a wall of incom-

combustible material (e.g. wood).
Installing the heater against a wall of
incombustible material (fig. 1)
The appliance can be installed in a hanging or standing
position. Allow at least 1 metre's clearance above the hea-
ter to enable sufficient heat circulation. If you want to
install the appliance as low as possible, the distance from
the centre of the wall duct to the floor should be dimen-
sion F (table 1, page 9).
The mounting plate (2) serves as a stencil to mark the
position of the duct.To be able to hang the casing over the
interior, a minimal clearance of 25 mm must be allowed
between the appliance and a windowsill or suchlike.The
minimum total free height for installation is dimension Y
(table 1, page 9).

The standard wall duct

Drill a horizontal hole in the wall, ø 230mm (E) in diame-
ter, to take the air-supply pipe.The wall duct should slope
at an angle of approx. 2º.
The standard wall duct is suitable for walls with a thick-
ness of 50 – 330 mm and the standard extended wall duct
for walls with a thickness of 50 – 600 mm. Depending on
the thickness of the wall, the inlet and outlet pipes should
be made to length, i.e.:
• length inlet pipe = wall thickness + 20 mm.
• length outlet pipe = wall thickness + 70 mm.
The tension members fixed to the wall grid can be made
to size after installation
