Power vent for a natural gas boiler
My 20 year-old Buderas boiler has a power vent through the basement wall. I figure the vent’s motor might need to be replaced at some point as it runs extensively in the winter. Are there universal after-market vent motors (or assemblies) for this?

Steamhead: that’s a good question! I am away from home at the moment, but will get back to you when I can have a close look at the unit. Here’s a photo in the meantime… perhaps you can recognize it.

A search on the web shows that there may be hundreds of draft inducer units made by many companies (FASCO, Jakel, Lenox, York, etc.) I contacted Field Controls and they suggested their PVG 100 unit, which can handle 55,000 BTU. My boiler has an input/ output rating of 132 Mbtu/hr and 109 Mbyu/hr.
The air-moving capacity of a draft inducer is its most important feature, How would I determine the capacity of (for example) the FASCO blower depicted here? Thanks for any suggestions or comments.

Alot easier to get the model # of the fasco thats on there now and just swap like for like. That stainless vent is very expensive you want to line up perfectly otherwise you won't save anything on a different model

Your better off going with the OEM model. You got at least 20 years out of it. That's not bad.

It is the AMATEK 117438-03 Blower assembly 7121-8998. A web search has uncovered one used unit on eBay. I have contacted AMATEK to see if it’s still available.
