2.3. “Dry montage” installation kit - based installation in a solid wall
Fire stopping mastic FireX (or analogue) should be applied directly to the wall around the installation opening within ≈5-10 mm from
it right before the fire damper mounting.
Dry montage kit consists of:
Two С-shape
parts –1 set
Shield flanges made of 40 mm thick Promatect-MT fire-resistant
material
1. Fire damper UVA 120H (Ø100 ÷ 315)
2. Solid wall (aerated concrete blocks, concrete,
masonry in min. thickness 115 mm)
3. Mineral wool, min. density 40 kg/m3
4. Fire stopping mastic FireX (or analogue)
5. Dry montage kit*
6. Mounting anchors (should be selected
accordingly to solid wall type).

Two С-shape
parts –1 set
Shield flanges made of 20 mm thick Promatect-MT fire-resistant
material
2 pcs.
Metal corner for joining shield flanges to the casing of the damper
Strip cut in
size
Promaseal –GT intumescent tape for filling the gap between
shield flange and casing
2 pcs.
DIN 967 M4x8 screw to install metal corners on the casing
2 pcs.
ISO 7049 3.5x13 screw to attach shield flange to the metal corner
4 pcs.
Construction screw 4.0x30 for joining together shield flange parts
“Dry montage” set’ assembling steps
It is easier to preinstall Dry montage kit on the damper casing first and then install the damper into the opening:
Take two metal corners [3] and attach them to
the casing of the damper by using two DIN 967
screws [5] and existing threaded holes, covered
with the red protecting tape.
Glue Promaseal-GT tape [4] to the casing on the
damper using previously attached metal corners
as a guide point.
Using two ISO 7049 screws [6], join shield flanges
[2] to the previously installed metal corners [3].

Using four ISO 7049 screws [7], join shield flanges
[2] to the previously installed shield flanges [1].
The junctions of the two flanges should not
overlap, but are at 90°.
