Thank you! Thank you!

The old one:

• Old and stinky.
• About 76" tall, 22" or 23" deep and 19.5" wide
• Stands up in hallway interior wall and pulls air in from hallway
• Natural gas
• Downflow heat exchanger
• 50,000 BTU output
• 62,500 BTU input
• 8.5" output duct on bottom
• Currently single chimney out the top (likely will need to be converted to double pipe "inlet-outlet" system)

The new one:

• Must meet ultra-low-NOx levels at 14ng/J (not "low-NOx" at 40ng/J) unless I can buy it before Thrusday
• 240V, up to possibly 40A could be a possibility for heat pump.
• Must work at 7,700 ft
• Must be mobile home rated
• AC option would be rather worthless
