SERVICE
If a condition persists or you are uncertain about the operation of the water heater contact a qualified service agency.
LEAKAGE CHECKPOINTS
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.

If cotton is wet, follow “Draining The Tank” section instructions in the “Maintenance” section and then remove fitting. Put pipe dope or teflon tape on the threads and replace. Then follow the instructions in “Filling the Water Heater” section.
