INSTRUCTIONS FOR INSTALLATION

The standard wall duct is suitable for walls with a

thickness 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 out-

let pipes should be made to length, i.e.:

Length of inlet pipe Length of outlet pipe

ART 2-01 Thickness of wall + 20mm Thickness of wall + 40mm

ART 3-01, 4-01 Thickness of wall + 20mm Thickness of wall + 30mm

ART 5-01, 6-01 Thickness of wall + 20mm Thickness of wall + 70mm

ART 8-02,10-02 Thickness of wall + 20mm Thickness of wall + 35mm

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, 5, page 49/50)

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 atten-

tion to the order (see figure). Take the whole and slide

the inlet pipe into the wall opening. Press the mounting

sheet up to the wall. Press the inlet pipe back in such a

way that the end of the pipe is level with the turned-back

edge of the mounting sheet.

From the outside, bring the wall grid with its attached

tension members into the inlet pipe. Bend the tension

members a little outwards, so that they will jam slightly

in the inlet pipe, keeping the grid in its place. Keep the

mark “Top” up when placing the wall grid. Slide the two

fastening clamps (5) over the tension members (6), taking

care that the fastening clamps catch on the turned-back

edge of the mounting sheet. Fix the screw-nuts onto the

tension members and tighten them by hand. Place the fas-

tening 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 49/50)

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 fas-

tening 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 49/50)

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 51/52)

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 49/50)

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.
