CAUTION
!
DO NOT operate this water heater with the rain cap
removed or recirculation 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, improper operation, personal injury or death.
DO NOT use field-supplied couplings to extend pipes.
Airflow restriction will occur and the water heater
pressure switches may cause intermittent problems.
