Your Envi heater may be a part of a limited recall that was recently initiated. A small number of Envi heaters sold between July 2015 and August 2016 may be affected and will require repair. We voluntarily initiated this recall in cooperation with the United States Consumer Product Safety Commission and Health Canada, which allows for any affected customers to have their heater repaired free of charge including shipping.

I never received the email so one or all of the following had to happen for me to avoid the potential of one of my units overheating and burning my house down.
1. The mounting hooks went missing.
2. I noticed the recall at the bottom of the search results.
3. The heater I installed wasn't included in the recall.
I bought both heaters at the same time but when I went to the website and entered the serial numbers only one of the heaters was subject to the recall. You probably already guessed it was the one that was never installed.
Remember the factory provided hooks that I couldn't find. I found them right after I completed the online recall application.
