This is a Heatwise BK-1 burner
Installed in 1993, it
was part of a new Slant-Fin boiler. The BK-1 was pre attached to the
boiler from a Home Depot in a crate. I replaced my furnace that
year. This unit has been totally under water in the 2000 Floyd hurricane
and the blower has been underwater at least two other times.
The other article on "starting a boiler that was
underwater" is about this blower. I replaced the original burner control in
2000 and two other times. In March, 2012 it started "buzzing" on startup.
I tried a replacement capacitor but that didn't last and finally replaced it
with a Beckett burner.
This looks different from the Heatwise home burner they sold until the company closed. The company that bought out Heatwise Another reason I replaced the entire unit, most parts were not available. I am posting this should you have the same unit, my furnace guy of 30 years never saw one of these.
After taking it apart, the motor bearing do not sound good when I spin it by hand. It looks as if the oil pump is starting to leak a bit.
