In rigid, standard walls and ceilings with a thickness less than or equal 140 mm, fire
dampers KWP-L should be mounted in thisway that an axis of the fire damper blade matches
the axis of the structure.
In the case of walls and ceilings thicker than 140 mm, fire dampers KWP-L should be
mounted in this way that keep the mounting limit, i.e. 200 mm, shown on fig.11.
5. Installation technology –Montage away from wall construction (silicate boards).
1. Make an opening in the wall with the dimensions 100 mm greater than the nominal
dimensions of the fire damper, i.e. B+100 and H+100.
2. Push the ventilation duct into the mounting hole and seal it with high density mineral
wool, 100 kg / m3 or more. Install the closed damper to the duct and support or suspend
it so that the damper and duct coaxiality is maintained. Install the damper so that its
drive is located outside the promat duct.
3. Coat the mineral wool placed in the mounting hole on both sides with PROMASTOP
Coating layer, approx. 1 mm thick and approx. 100 mm wide.
4. After installing the damper, and establishing its target position at a distance L from the
fire barrier, proceed with the montage of the promat duct according to the drawing and
the following guidelines:
a. Make spacing band using PROMATECT-L500 panels with a thickness of 35 mm and
dimensions 150x100 mm. For the width B≤300 mm, make two bands, for a width
B> 300 mm, make four bands. For an L≥1000 mm distance, make an additional four
bands.
b. Make individual sections of the promat duct made of PROMATECT-L500 panels
with a thickness of 50 mm as in the drawing.
c. Suspend the promat duct along with the spacing strips in the spacing L + 55 using
rails and threaded rods. Connect the duct with the wall using PROMAT K84
adhesive.
d. Connect the sides of the duct together using adhesive and 6.0x90 screws, spacing
about 200 mm.
e. On the circumference of the damper, in place of the swelling gasket, place strips
of mineral wool(density 100 kg / m3 or more) with a profile of 46x30.
f. Make frontal bands of PROMATECT-L500 panels with a thickness of 50 mm and
dimensions as shown in the drawing. Connect them to the duct using adhesive and
screws.
g. In the place where the duct connects to the frontal band, make a muff joint band
made of PROMATECT-H board, 20 mm thick and 100 mm wide. Remaining
dimensions should be selected according to the drawing. Connect the band to the
duct using adhesive and 4.5x50 screws.
h. Place the sealing band made of PROMATECT-L500 panels with a thickness of 50
mm and dimensions according to the figure at the connection of the promat duct
with the fire barrier.
i. Connect the band with the duct using adhesive and screws 6.0x90. The band must
be connected the wall using the M8 anchors in a spacing of approx. 200 mm
ATTENTION: In case of lack of information regarding the damper installation, the assembly of the
duct made of PROMAT boards should be carried out in accordance with the PROMADUCT-500
System, based on the technical approval AT-15-3550 / 2015.
