WARNING – PROPANE MODEL
Water heaters for propane gas are different from natural gas models. A natural gas heater will not function
safely on propane gas and no attempt should be made to convert a heater from natural gas to propane gas.
Propane gas must be used with great caution. It is highly explosive and heavier than air. It collects first in the
low areas making its odor difficult to detect. If propane gas is present or even suspected, do not attempt to
find the cause yourself. Ventilate the room, then call your gas supplier or service agent. Keep area clear until
a service agent has been called.
