GSW PART NO.70999 REV.G (03-12) Installation Check List, Pressure BUILD-UP in a Water System

Page 7

Pressure rating of the valve must not exceed the working pressure shown on the rating plate of the water heater. The discharge capacity must be equal to or greater than the input to the water heater. Temperature and Pressure Relief valve piping must terminate 6 inches, no more than 12” (reference the applicable code) above a floor drain or external to the building. Do not thread, cap, or plug the end of this discharge line. Be certain that no contact is made with any live electrical part. Do not connect discharge line directly to drain. See Figure 2. To prevent bodily injury, hazard to life or damage to property, the relief valve must be allowed to discharge water in the event of excessive temperature or pressure developing in the water heater. The function of the temperature and pressure relief valve is to discharge water in quantities should circumstances demand. If the discharge pipe is not directed to drain as shown in Figure 2 or other suitable means, the water flow may cause property damage.

The discharge line:

1)must not be smaller than the outlet pipe size of the relief valve,

2)must not be plugged or blocked,

3)must be material capable of withstanding 210°F without distortion,

4)must be installed so as to allow complete drainage of both temperature and pressure relief valve,

5)must terminate at an adequate drain, and

6)must not have any valve between the relief valve and the water heater.

WARNING

Do not attempt to operate this water heater with the cold water inlet valve closed. Manually operate the Temperature and Pressure Relief valve at least once a year. Standing clear of the outlet (discharge water may be hot), lift and release the lever handle on the Temperature and Pressure Relief valve to make the valve operate freely.

NEVER OPERATE THE HEATER IF IT IS NOT COMPLETELY FILLED WITH WATER. TO MAKE SURE THE HEATER IS FILLED, OPEN A HOT WATER TAP UNTIL A FULL FLOW OF WATER IS VISIBLE WITH NO AIR ESCAPING.

PRESSURE BUILD-UP IN A WATER SYSTEM

During the heating cycle of the water heater the water expands, creating a pressure build-up in the water system. The water supply meter may contain a check valve or back flow preventer. This will create a closed water system. A temperature and pressure relief valve must be installed on the water heater (150 PSI maximum pressure setting. See temperature and pressure relief valve).

If a water heater is installed in a closed water supply system, the relief valve will discharge water as the volume of water expands with rising water temperatures. This is normal and indicates a normal functioning of the relief valve. Do not plug the relief valve. Only if the discharge from the relief valve is continuous or for an extended period of time would this indicate a malfunction. Have the operation of the heater checked by a qualified serviceman.

INSTALLATION CHECK LIST

Check Here

1. Have the vent location limitations and minimum height for vent termination and maximum vent length been checked?

2. Are the terminal and vent pipes installed and sealed properly?

3. Has the gas piping been leak tested?

4. Is there at least a 1” clearance between the water heater and combustible materials, 20” at the top and 1” around the vent pipe?

5. Have you taken steps to prevent water damage in case of leaks?

6. Is the diptube installed in the cold water inlet connection?

7. Is the water heater completely filled with water?

8.Does the gas piping conform with the recommendations of your Local Gas Utility Company?

9. Is the vent terminal opening unobstructed?

10.Is a temperature and pressure relief valve installed?

11.Is the drain pipe from the T & P valve unobstructed?

12.Has all plastic and cardboard packaging material been removed from the heater and venting?

IF the answer to all of the above questions is “YES” proceed with lighting the heater.
