! CAUTION
DO NOT operate this water heater with the rain cap removed or recircu-
lation of combustion products may occur. Water may also collect inside
larger combustion-air pipe and flow to the burner assembly. Failure to
follow this warning could result in product damage, or improper opera-
tion, personal injury or death.
DO NOT use field-supplied couplings to extend pipes. Airflow restric-
tion will occur and the water heater pressure switches may cause in-
termittent problems.
