Professionally installed 3/10/10. Did EXTENSIVE research on this and other Kenmore water heaters prior to purchase. Replaced a 14 year old 'traditional' WH with constant pilot light that vented to the chimney.
Took note of all issues listed here (and elsewhere) that were encountered by others, hoped for the best. This one is made by AO Smith, a good thing.
Upon install, unit would not stay lit - thought my worst fears were recognized...Fortunately, I purchased the mac-daddy service plan.
Technician came out same day I called, ran tests - determined venting pipe (PVC) was encountering too much resistance due to length of PVC and/or elbows in exhaust PVC. Solution? Shortened PVC to eliminate length/quantity of elbows, has worked like a champ ever since. Will update later if status/satisfaction changes.
“I'm very happy with my purchase of the Kenmore water heater”
“Heater works perfect..Highly recommended if you have room.”
