I don't have to get it inspected.  I don't need a permit.  I'll never
get a fine.

Put that in your furnace and smoke it.

The Fire Marshall is out of the picture.

They (mostly) don't have primary air adjustment shutters.  So how do
you tune them?

But they don't heat the heat exchanger galley as evenly as long,
slotted up-shot burners.

Like what - like maybe pull them out and give them a shake every 5
years?

Anything is bound to be more efficient with a second heat exchanger.

For combustion intake?

Cold air, hardly any pressure or measurable flow?

Even if they "rot" and "crack", worst that can happen is that the
furnace starts sucking intake combustion air from around the furnace -
something it would normally do anyways.

There is already a supply duct running down into the furnace room from
an outside vent about 5 ft above grade.  The bottom of the duct was
open - allowing outside air to flood into the furnace room.  I closed
off the bottom of the duct and ran 4 flex lines (4") from the duct to
the furnace cabinet (2 for the primary combustion air and 2 for draft
air).

Yup, it sure is.
