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.

FIGURE 40

Never use this water heater unless it is completely filled with water. To prevent damage to the tank, the tank must be filled with water. Water must flow from the hot water faucet before turning “ON” gas to the water heater.

A*Condensation may be seen on pipes in humid weather or pipe connections may be leaking.

B.Small amounts of water from temperature-pressure relief valve may be due to thermal expansion or high water pressure in your area.

C.*The temperature-pressure relief valve may be leaking at the tank fitting.

D.Water from a drain valve may be due to the valve being slightly opened.

E.*The drain valve may be leaking at the tank fitting.

F.Water in the water heater bottom or on the floor may be from condensation, loose connections, or the relief valve. DO NOT replace the water heater until a full inspection of all possible water sources is made and necessary corrective steps taken.

G.*The hose from the tank to the heat engine may be leaking at the tank fitting.

H.*The fittings at the circulation pump may be leaking.

Leakage from other appliances, water lines, or ground seepage should also be checked.

*To check where threaded portions enter the tank, insert cotton swab between jacket opening and fitting. 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.
