For propane gas water heaters, change “G” to “L” or ”N” to “P” or ”Y” to “H,” or “X” to “C,”in the model number. For example: 12 40 PACT, 6 50 HBDS, or 6 75 CRRS. ‡Some propane gas models have slightly lower inputs than natural gas models, which may reduce First Hour Rating and recovery by up to 3 gallons on propane models.
