Can you install or adapt a power vent on a standard water heater

Darek, I just installed a non direct vent water heater (draft type) where a direct vent water heater was in my garage. I used the larger of the two vent pipes that were on the old direct vent water heater to vent the new tank and make sure that the vent pipe was sealed and no exhaust gases could leak back into the garage. I know this is not correct, but it was a quick fix at the time. My question is can you install or adapt a power vent on a standard water heater (draft type) without having to replace the tank or spend a lot of money?

Hi Dan,
I've answered almost identical question here: power vent on regular water heater  Unfortunately the answer is negative. The entire design of the water heater must be comparable with the power vent assembly.
I’ve seen people doing it by using inline draft inducer, but unless your particular model has been approved for power venting (call its manufacturer and ask if it can be converted) this is not a correct and safe way to vent natural draft water heater. Natural draft water heaters require a chimney / must discharge above the roof.
