FITTING AN RSH SERIES PRV INTO A STUD WALL PARTITION
NOTE: Local building or fire codes may supersede these instructions. Consult your local AHJ
before proceeding.
a) First note the orientation of the PRV and its placement into the
enclosure wall. The red arrows on the sticker are always on the top
of the vent and denote the direction the pressurized air is to be
relieved.
b) Measure the PRV wall liner and add a 1/2 inch (12mm) to the measurement mark out and cut a
hole into the stud partition. (Note that the larger of the measurements is always the width).
c) The hole to be cut must be lined with studs and plasterboard. It is recommended to use a
vertical stud as a starting point. Once the stud has been found, mark a vertical line on the
plasterboard along the edge of the stud. Now draw and cut along a line measured 1/2 inch
(12mm) from the initial stud marker. From here mark and cut out the rest of the hole.
