Service
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
to check the water heater.
Read this manual first. Then before checking the water heater make
sure the gas supply has been turned “OFF”, and never turn the gas “ON” before the tank is completely full of water.
