I believe that this should read 2.25 GAL/hr. A similiar heater in other types of aircraft (Cessa 310's, 402's, Piper Seneca, Aztec, Navajo, etc) typically burn just over 2 gallons per hour.

This is the service bulletin that describes the changes to the basic installed heaters:

Just quoting the POH on the 2.25lbs/hr. FWIW, the C&D Associates heater I replaced the Janitrol with burns 1.5gph, max according to its Operating handbook. The heaters in 337's are 25K BTU, the larger planes might have bigger heaters, and higher fuel burn rates.

That's what I'm saying, it was a typo from Cessna, and it never was corrected. God forbid that Cessna would put out wrong information.
Think about it, 1/3 gph? That is so absurd that this is why a red flag popped up.

Skymaster, Seneca, Seminole, Baron are all comparable sized cabins as far as cubic foot areas, so they all have the same size/family of heaters.
