Suspending a Modine PDP Unit: The most common method of suspending Modine Gas Unit Model PDP Heaters is to utilize 3/8” threaded rods. On all PDP units, except sizes 350 and 400, two tapped holes (3/8-16) are located in the top of the unit to receive threaded rods. The 350 and 400 models have four tapped holes in the top of the unit for threaded rods.

Note: When ordering parts for your Modine Heaters, please have the following numbers ready: Model Number, Serial Number, Power Code Number and Control Code. This information can be found on the serial plate on the side of the unit.
