Last week I was here with a problem with an old Gun type oil furnace @ 1961.
As a result of some good advice I received, yesterday I replaced it with a modern, more efficient Olsen furnace of the same BTU output.
I works great, But!
Early this morning, the furnace burner cut in (OK) Then the blower cut in like a hurricane!
The output (and noise) seems far too strong.
Worse, the sequence runs like this:
Burner cuts in.
Soon after the fan cuts in (with gusto).
Later burner cuts out.
Soon after Fan cuts out.
30 seconds later Fan cuts back in again (I assume scavenging some residual heat from the heat exchanger) then cut out again a few seconds later.
All this repeats until the house temp has stabilized.
My feeling is, if the fan speed were slower, noise would be reduced, and the fan 'cycling' could be cut down to a point were, the cooling of the heat exchanger (via the fan) would be more in tune with the Burner output.
Any thoughts on this?
Warranty is not an issue here.
The fan motor appears to be direct drive (sadly) what sort of speed control could be used?
