Greenheck Fan PVE-45, PVE-55, PVE-35 Access Panel Description and Location, Rail Mounting / Layout

Rail Mounting / Layout

An alternative method of unit installation is to mount the unit on rails supplied by others. The purpose of mounting the unit on either rails or the GKD curb is to elevate the unit away from moisture conditions and to provide proper clearance for installation of water drain traps.

•Rails should be designed to handle the weight of the PVe unit, taking into consideration weight per square inch on bearing surfaces. Rails should be positioned as shown in the drawing below, taking into consideration proper load distribution and support by roof support elements.

•Make sure that rail positioning does not interfere with either the RA Intake duct or the optional straight down SA Discharge duct.

•Rails should extend beyond the unit a minimum of 12 inches.

•Set unit on rails.
