INSTRUCTIONS FOR INSTALLATION
mounting sheet. Fix the screw-nuts onto the tension
members and tighten them by hand. Place the fastening
clamps onto the horizontal centre line of the inlet pipe.
See also the marks in the mounting sheet.
The exterior wall duct with telescopic inlet
pipe
This is suitable for wall thicknesses of 250 – 440 mm
without shortening the parts of the inlet pipe. By short-
ening 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, 3, 5, page 57/58)
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 (5) 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.
Attach the sealing ring (3) and the wall ring (4) to the half
inlet pipe (see ffigure for the correct order).Take the
whole and, from the inside, slide the half inlet pipe
through the created wall opening into the part of the
inlet pipe already mounted.While doing so, make sure the
the two tension members (6) stick through the fastening
clamps. Press the mounting sheet up to the wall. Appply
the screw-nuts onto the tension members (6) and tighten
them by hand against the fastening clamps (5).
Fastening the mounting sheet
(fig. 1, 3, 5, page 57/58)
Caution: Level the mounting sheet, make sure that the
inlet pipe goes down towards the outside. (1 cm to 1 m)
and that the wall grid lies straight against the exterior
wall. Then, any condensation will never get into the
heater because of the downwards flow of the pipe.
• Now tighten the screw nuts on the tension members
• Saw or cut the tension members so that they do not
stick out from the fastening clamps (5).
• Drill the hole for the key bolt (7).
• Attach the key bolt and attach the mounting sheet using
the bolt (8) and washer (9).
Installation to a wall of inflammable material
(fig. 8, 10, 12, page 59/60)
When the appliance is installed to a wall of flammable
material, the wall duct should be executed as follows.
• On the spot of the duct, create a square opening in the
wall (
M mm).
• In the case of compressible walls, fill up the space all
round the opening well, so that the wall cannot be
crushed.
• In addition, replace the bolt (8) by e.g. a wood screwed
bolt.
• On the room side, put the heat shield (14) between the
mounting sheet (2) and the wall.
• On the outside of the wall, using 4 screws (16), attach
siluminplate (15).
The heat shield (14) and the silumin plate (15) are packed
together and are available from your dealer. Assembling
the wall duct is otherwise the same as previously
described.
N.B. To calculate the length of the inlet and outlet pipe,
the thickness of siluminplate (15) should be included.
Installation of the interior
(fig.2, 4, 6, page 57/58)
Slide the adjusted outlet pipe into the grid opening. Slide
the two Silicon Rubber Tulles (packed with the glass silk
rope) over the bolts (10) and into the holes of the back
plate.
This prevents possible dirt and deposit from settling onto
the wall.Take the interior and put it with the bottom
edge on the two supports of the mounting sheet. Keep
the interior balanced and slide the outlet pipe a little bit
into the outlet opening of the interior for support. Now
slide the interior against the mounting sheet, taking care
that the turned-back edge of the mounting sheet fits into
the inlet bush on the back side of the interior and that
the bolts (10) stick through the clamps (11). Attach screw
nuts and washers to the bolts (10) and tighten closely up
to the stop.Then slide the screw spindle (12) into the
clamp (13). Fix the screw nut and washer to the screw
spindle (12) and tighten until the interior is standing paral-
lel to the wall.
N.B. If easy accessible, e.g. on the ground floor, the outlet
pipe can also be mounted from the outside after the grid
interior sheet and the basket have been disassembled.
