Give your old Harman Pellet Pro a quick change!

[Don2222]

Hello
The old Pellet Pro I or Pellet Pro II Harman stoves and VC Reliance pellet stoves have Exhaust or Combustion blowers that have 3 bolts to hold the motor on the exhaust housing. Therefore the only way to clean the blades and exhaust chamber is to remove the entire exhaust housing. This can be difficult. However I newer quick change housing can be cut and modified so a new Blower , Harman or any exhaust blower brand with a 6” round mounting hub can be easily installed!
Don't forget to seal the new quick change housing to the inside of the Harman exhaust flange with High Temperature Silicone RTV,

Yep I agree. The one piece blower is expensive and makes service and clean out difficult.

I did this to my VC Reliance which is Pellet Pro mechanicals. see below:

So after living with the stove for a few weeks I had come to the conclusion that the exhaust blower was the source of most of the noise.
I took it out and ran it on the bench and noticed that besides the slightly unbalanced impeller, that the motor bearings were shot. It would hit a resonance point and really start a racket.

Looking around I saw that a replacement blower was north of $200, almost as much as I paid for the stove.
I also didn't like all the hardware that needed to be removed in order to clean the blower and the plenum beneath it.
Looking around I found a general replacement blower sold by Pellethead on Ebay that seemed to fit the bill, best of all it was only $99.

It had the same 4.75" impeller, a 3000 rpm motor, and it drew about the same current. It was also ball bearing and made by Fasco so that was the deal clincher.
I ordered the unit and installed it last Friday, much quieter.
I had to drill out the set screw on the old impeller, it was long since rusted tight.
After removing the old motor I used the supplied gasket to cut a 5" hole on the top of the blower housing to mount the new assembly. I made sure to paint the bottom of the mounting plate and impeller with high temperature stove paint and coat the motor shaft and set screw with never seize so future repairs would be easier.

Now when I want to remove the blower, it is only 6 small screws and the whole unit will lift off making cleaning much easier.
Its a lot quieter too when it runs.
