Greetings all,
After many years of service my 2400 was way over due for service. Did a complete burn pot overhaul and have a nice blue flame.
Combustion fan was getting quite noisy and loud so I replaced the bearings with fresh ones. Motor spins very free but the noise level is still quite high.
Out on the bench all is quiet but when reinstalled no good...no problem with motor/blower operation just the noise level.
Could this be because of the packing installed between the blower shrouding? I reused the old packing as it looked ok.
Another question the O ring that connects the piping from heater (heat exchanger) to the tru wall pipe is not great..is this a needed concern. No smell is present.
Any help would be greatly appreciated.
Mike.
