weil-mclain ultra 80

siteman

I have a weil-mclain ultra 80 boiler and it has started to make a squeeling noise which sounds like it is coming from out of the blower motor and it started after I had to manually reset it from a hard lockout,can any one tell me what might be going on  thanks

Gas Valve

When does this noise happen? I have had several of these where the gaskets where bad and caused a whining noise. Hard to tell when I can't hear it though.

How old is the unit?

Has it had annual maintenance? Do you have the I and O manual handy? What Series is it 1, 2 or 3? Do  you know where the air silencer is located, if so check to make sure there is no blockage.
