All good points.
I have to look further into "how to adapt a 2" or 3" pipe to the Mag. combstion blower and make the whole thing look good....
This area of the basemant is finished, to my lovely wife's specifications.
My concern is NOT to have a bunch of cold air leakage caused by "not so positive connections" ?
As stated previously, I have a power venter on the oil boiler, which will run at times.
I'll have to pipe it all up in something 'pretty' until it enters my suspended ceiling, above the stove. ( maybe small black stove pipe, or painted PVC)
I guess I could run it along an adjacent wall, at the floor to enter an unfinished space ?
Another question that came to mind is;
What distance would you suspect that little fan will draw ? ( duct run)
Thx, Mossy Beard
