Intended use

• Compensating frame for mounting on the wall sleeve (DN 162) if the wall thickness is insufficient. The wall sleeve must have an incline of 1 to 2 % to the exterior wall. For wall insulation sleeve → Shell installation instructions
• For a wall thickness < 320 mm use one/several PPB 30 ARE / PPB 30 ARW compensating frames (each 55 mm deep). This is important to achieve the prescribed minimum wall thickness.
• PPB 30 AE / PPB 30 AW external cover: To mount the external cover on the compensating frames, use the PPB 30 ARE BB / PPB 30 ARW BB fixing plate. It is imperative to comply with the required wall sleeve projection from the exterior wall: Projection = wall thickness + depth of the PPB 30 ARE / PPB 30 ARW + 5...10 mm.
• The PPB 30 AK external cover is mounted on the PPB 30 ARE / PPB 30 ARW compensating frame without a fixing plate.
