Water Heater Size

How does one determine the water heater size on a 2003 30' classic? 6 or 10

Look at model number on label plate in the heater compartment. Then enter number into search engine preceded by manufacturer's name. Result should show the gallons size.

Text extract from "Atwood LITERATURE NUMBER MPD 93755, L.P. GAS WATER HEATER 4 - 6 - 10 GALLON Models 4-E & 10-E":



G C H 6 AA - 10 E/P


C = Combination Gas and AC Electric

H = Engine Heat Exchange

6 = 4 - 6 - 10 gallon capacity

AA = Heating Element (SCREW-IN OR BOLT-ON)

10 = Revision (NUMBER)

E/P = Electronic Ignition or Pilot Relight
