INSTRUCTIONS FOR INSTALLATION
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. 3)
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. 2)
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 ( 280 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) (fig 3) 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).
fig. 4
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.4)
Slide the adjusted outlet pipe into the gird 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.

Connection of the gas supply

The connection has a 3/8" BSP inside thread. If the supply
pipe enters the appliance through the back plate, press out
the disc in the plate. 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:
• Expel all air from the supply pipes/hoses before coupling
to the appliance.
• Do not turn the coupling tap when connecting it to the
gas supply.
• Avoid any pressure on the control tap and pipes.
• Check that all connections are gastight.
