Venmar Ventilation has received several reports of major home fires where the suspected cause is a heat recovery system. Therefore, Venmar Ventilation released this press release which affects heat recovery systems as these systems can fail and pose a potential fire hazard to homeowners.

I looked into mine and it was determined that I had one of the HRV’s in question. (Model: 43720) You can fill out the Request Form Product Recall - Safety Upgrade Program and find out if your model is listed as well.

The recall is for models manufactured between 1991 and 2001 as well as between October 2006 and August 2007.
Owners of air exchange systems that are covered by this Safety Upgrade Program must immediately turn their unit off and unplug it, and contact Venmar as soon as possible. (1 866-441-4645) or by visiting their website at www.venmar.ca
