I'm with TURTLE on this one.
Put in a solid core door for reduction of noise. Don't do that until
you have replaced Source air inlet. I believe ducting it in from the
ceiling is a do-able idea. However it makes more stuff to filter and
such. Filtering will not be for your breathing air, but to keep the
ducts from clogging with bird nests and dust and other stuff.
Just as a comparison to your heater system, those manufactured
fireplaces use three walled Chimney ducting for the flue. Between the
outer two pipes, is where the chimney gets it's cooling air. that air
is then delivered back up between the inner two pipes. Draw yourself a
picture and see if it makes sense to you...............It does
work.The actual exhaust from the fire ( smoke and primary heat) goes
up though the inside pipe proper.

Reason for the explanation is to help understand also, that you could
use a triple wall pipe situation for your "chimney" for the heater,
and still put a solid core door in there. That way, you won't have to
make any major new ducting routes.

This is just a thought for pondering, as I think it would be better
than code would require also, and could be something that you may be
able to find as a kit already manufactured.............

I've never heard of the system you are describing, but it makes a good
picture in my head the way you described it, Mike.

Good luck.


This is Turtle.

He is drawing air to burn from his house and to the code it could be ok but in
general it is just not nice to burn the same air you breath in a house.
