This is not the first time I have bought an item from Home Depot that has been damaged or has missing parts
Items with missing parts
Charbroil gas grill
Glo warm wall gas heaters.
This last episode was with a power vent gas water heater.
The heater out of the box had deep dent in it.
The kit supplied did not have vital saftey parts included, a vent adapter and blower mounting screws.
I called the Rheem hotline to report the the missing parts and the fella said "go back to the store and buy them"
Now, this is the phone number on the box that say's" Call this number first before you do anything else "......Do not return this product to the store. We will help you solve your problem
Needless to say there was a few more dents when I returned it.
