Installation to a wall of non-flammable material
(fig. 6, 8, pg. 58, 59)
The models are suitable for hanging installation only. Allow
at least 1 metre’s clearance above the heater to enable
sufficient heat circulation. When installed hanging, at least
1 m free space should be kept above the appliance to
allow sufficient heat dissipation. When intalled standing,
the bottom of the mounting sheet (2) should stand on the
floor, this is the minimum height between the floor and
centre of wall duct (size F. fig 6, 8, pg. 58, 59).
The mounting plate (2) serves as a template 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 allo-
wed between the appliance and a windowsill or suchlike.
The minimum clear installation height (Y) required for
each of the various models is listed in the table on page
60.
The standard wall duct
Drill a horizontal hole in the wall, ø E to take the air-sup-
ply 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 of inlet pipe Length of outlet pipe
STYLE 3 Thickness of wall + 20mm Thickness of wall + 40mm
STYLE 4, 5 Thickness of wall + 20mm Thickness of wall + 30mm
The tension members fixed to the wall grid can be made
to size after installation
Installation of the standard exterior wall duct
(fig. 1, 3, page 57)
Slide the adjusted inlet pipe (1) through the mounting
sheet (2), with the turned-back edge facing the mark (45º
top left) in the mounting sheet. Slide the sealing ring (3)
and the wall ring (4) around the inlet pipe, paying attention
to the order (see figure). Take the whole and slide the
inlet pipe into the wall opening. Press the mounting
