If a condition persists or you are uncertain about the operation of
the water heater contact a service agency.
Use this guide to check a "Leaking" water heater. Many suspected
"Leakers" are not leaking tanks. Often the source of the water can
be found and corrected.
If you are not thoroughly familiar with gas codes, your water heater,
and safety practices, contact your gas supplier or qualified installer
