Just when you think you've seen it all...

Ran across a 20 ton Byrant LP RTU today that is data tagged at 3.2" wc
on the manifold and verified by the manufacture as such. That's a
first for me. Every other piece of LP equipment I've ever seen runs
10" wc on the manifold.

I always check the tags... as anything's possible. I've seen water heaters
with low 9" and heating units up to 11".
If I recall correctly, the Lennox Pulse was an unusual number.

Yea if memory serves, the NG G21 was 2"wc and LP was 9"wc. I seem to
remember the first generation was higher.

"Unusual"?? hehe. That's quite an understatement. That furnace was
undoubtedly the strangest machine ever. And the "flapper". Now that
was a piece of artwork. And then the ol water pressure test to check
for heat exchanger leaks. Now that was some engineering work.
POS. Gotta love ol "Dave".

Was at a house today with a Pulse...
Manifold pressure for Nat is 2" while LP was to be set at 9"

Another POS design is the Syder General GUA... pressurized heat exchanger...
