Re: Decent 20-30 KW standby generator

said by pandora:

No chimney, no flue, no way to vent propane at this time from inside the house (other than cooktops).

Modern high efficiency furnaces don't require a chimney. The flue is essentially just a couple of plastic pipes. Ours just runs straight out the side wall of the house nearest the furnace.

The furnace would install in your existing ductwork, assuming you have ductwork in place already.

concentric vent sample
I have to agree with TheMG on this.
Todays furnaces use PVC piping for the combustion air exhaust and intake.
You can run the pipes through the roof or exterior side wall.
Most (if not all) offer a Concentric Vent kit that pipes both combustion air and exhaust in to one pipe so there is only one penetration through the wall or roof.
You can even paint out the pipe to hide it.

Edit
In addition, because the combustion air is piped it, you don't have to worry about combustion air louvers or the furnace using warm room air for combustion air.
