Mounting of MRH with adjustable sidebars
*The MRH centreline can deviate from the vertical for max. +/- 5° - this can be combined with the sidebar setting.
**Avoid additional load to MRH due to weight of eventual duct with flexible connection.
*** Choose the direction of opening to ridge considering access/snow deposition/wind/pitch. Roof insulation and
flashing is not shown in the installation examples.
1 - Three height positions of sidebars (0, 250, 500 mm
from the bottom);
2 - The sidebars adjust to the roof pitch and fasten all
bolts (2 or 3 bolts each sidebar, depending on the
sidebar position);
3 - Fasten the bars to the roof frame with bolts or
studs;
4 - Fasten the sidebar with attached screws to the
wall of MRH;
5 - Remove the hinges.
