Slide the two mounting brackets (3) over the tension rods
so that they hook over the edge of the mounting plate and
the inlet pipe.
Screw the wall duct firmly into position with two nuts
while turning the mounting plate and the wall grille to the
correct position (the two bolts on the mounting plate and
the tension rods should be horizontal).
Slide the mounting plate into the position previously
marked on wall.

The exterior wall duct with telescopic inlet pipe

This is suitable for wall thicknesses of 250 – 440 mm with-
out shortening the parts of the inlet pipe. By shortening
the pipe's parts, this exterior wall duct can be adapted for
thicknesses of 70 – 250 mm. The outlet pipe should be
adjusted. The tension members attached to the wall grid
can be shortened after the wall duct has been mounted. If
the telescopic inlet pipe is applied for wall thicknesses of
70 – 250 mm, both parts of the pipe should be shortened,
i.e.:
• the part of the inlet pipe on the side of the wall grid equal
to the thickness of the wall
• the part of the pipe on the side of the heater to a length
equalling the wall thickness minus 20 mm.
CAUTION: do not cut the pipe parts on the side where
the fastening clamps have been applied.
Installation of the wall duct with telescopic
inlet pipe (fig. 1)
From the outside, put the wall grid, together with the
attached half inlet pipe into the created wall opening,
keeping "Top" up when placing the wall grid. Slide the
other half of the inlet pipe through the mounting sheet (2),
making sure that the inserted fastening clamps (3) lie on
the horizontal centre line (see the marks in the mounting
sheet). They should catch on the turned-back edge of the
mounting sheet.
From the inside, slide the half inlet pipe through the cre-
ated wall opening into the part of the inlet pipe already
mounted. While doing so, make sure the the two tension
members (4) stick through the fastening clamps (3). Press

the mounting sheet up to the wall. Appply the screw-nuts
onto the tension members (4) and tighten them by hand
against the fastening clamps (3).

Installation against a combustible wall

Marking the position of the wall duct on the wall is done
in the same way as for a non-combustible wall.
Make a 280 mm square hole through the outer wall, at the
centre of the round hole in the mounting plate.
If it is a cavity wall, fill the cavity well so that the sections
do not get compressed.
Fit the extra silumin plate with 4 screws onto the outside
of the wall.
This extra plate, to enable the duct to be used on a com-
bustible wall, is available as a separate order.
The wall duct is then fitted in the same manner as
described for a non-combustible wall.
N.B. To calculate the length of the inlet and outlet pipe,
the thickness of siluminplate (15) should be included.

Positioning the aluminium shield

When installing the convector the aluminium shield should
be placed under the foot of the interior. Slide the shield
back far enough so that the front is level with the front of
the steel foot.

Positioning the convector

Slide the outlet pipe into the wall grille and stand the con-
vector on the floor plate.
Slide the convector against the wall so that the outlet fits
over the outlet pipe and the two mounting brackets over
the bolts on the mounting plate.
Screw the two nuts on lightly.

Connection of the gas supply

The connection has a 3/8" inside thread. An approved
connecting tap with coupling should be used in the supply
pipe (For Belgium this should be B.G.V. approved). The
connecting tap with coupling should be fitted outside the
casing. Furthermore:
