Important information about plastering

DANGER Fire may spread if ER-UPB housing is incorrectly installed.

Any gap remaining between the housing and shaft/tiles must be fully sealed with non-flammable materials resistant to deformation.

Minimum overlap required for the ventilation shaft (without tiles, etc.) in the area of the connection duct 10 mm.
Max. compensable plaster overshoot 7 mm.
Max. protruding housing edge 20 mm, can be levelled out with ER-AR EC compensating frame.
Installation at a depth of 50 to 100 mm can be compensated for with the ER-MR two-part wall frame.
The gap remaining between the housing and shaft must be fully sealed with non-flammable materials that are resistant to deformation so that incorrect air is not drawn in.

We recommend keeping these installation and operating instructions until final installation in the housing.
