STEPS TO INSTALL YOUR

WARNING

If the temperature and pressure relief valve ever needs replacing, use onty a valve specified by local codes, but not less than a combination temperature and pressure relief valve certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment or materials meeting the requirements for Relief Valves and Automatic Gas Shutoff Devices for Hot Water Supply Systems, as specified in the latest edition of ANSI Z21.22. This valve must be marked with a maximum set pressure not to exceed the marked maximum working pressure of the water heater. (The relief valve provided

with this heater meets these.requirements.) Install the replacement valve into the opening provided and marked for this purpose on the water heater. Do not place any valve between the temperature and pressure relief valve and the tank. Orient it or provide tubing so that any discharge from the valve witll exit only within 6 in. above (or any distance) below the structural floor and cannot contact any live electrical part. The discharge opening must not be blocked or reduced in size under any circumstances. For maintenance and replacement of the temperature and pressure relief valve see pages 10 and 11.

IMPORTANT; TO HELP PREVENT POSSIBLE DAMAGE TO THE WATER HEATER, WE SUGGEST YOU READ STEP 5 CAREFULLY.

DRAIN PIPE FROM TEMPERATURE AND

• PRESSURE RELIEF VALVE.

WARNING

The temperature and pressure relief valve is designed to automatically open to vent dangerously high temperature or pressure from the water heater. To vent the temperature or pressure,the drain pipe must allow a free flow of water to a floor drain or other suitable drain point (CHECK LOCAL CODES). If it cannot vent properly, and fast enough, the heater could burst and damage property, or cause severe personal injury. BE SURETO FOLLOW ALL GUIDES BELOW WHEN INSTALLINGTHIS DRAIN PIPE. (Also read the safety guides on page 2, and "WARNING" above.)

DO NOToperate the water heater unless the temperature and pres- sure relief valve is in place, correctly piped and working properly.

CAUTION: Do not apply heat to the fitting when making sweat connections to the temperature and pressure relief valve. Sweat an adaptor to the copper line before connecting to the valve. It is imperative that no heat be applied to the water heater connec- tions as they are joinedto the non-metalic structureof the heater.

•If the temperature and pressure relief valve needs

repositioning, removing or replacing, two wrenches must be used -- one to turn the valve and one to hold the union

hex nut. Never use only one wrench.

=Use 3/4" pipe and fittings the same size as the outlet of the temperature and pressure relief valve. DO NOT USE A SMALLER SIZE PIPE.

•Use material that will withstand hot water (210°F), and will not distort, deform, melt, collapse, etc. Copper or CPVC

plastic pipe and fittings are best to use, to keep weight stress on the center hex union at a minimum.

•DO NOT install valves or fittings in the drain pipe that will restrict drain flow.

•The end of the drain pipe must not have threads, so a fitting or cap could be turned onto it by mistake.

•The end of the drain pipe must be no more than 6 in, (maximum air gap) above the floor drain as FIG. 2 shows.

•The drain run must not have any dips, bends or low spots that will trap water. ALL water must drain from the pipe and relief valve.

•Be sure freezing temperatures will not affect the flow of ' water from the drain pipe.

•Support the drain pipe in some manner to prevent stress on the water heater fitting. For example, use metal strapping or wire to an overhead point as shown in FIG. 2.

Following ALL of the above RULES, install the drain pipe. Use pipe thread seal compound on male pipe threads and tighten all connections. Solder all sweat connections. (READ

CAUTION IN STEP 5,) REMEMBER DO NOT RESTRICTTHE DRAIN PIPE INANY WAY.

,, DRAIN VALVE (FIG. 2).

The drain valve is factory installed. To face the drain valve

outlet in the opposite direction, toward the drain point, FIRST LOOSEN THE UNION HEX NUT. DO NOT ATTEMPT TO

TURN THE DRAIN VALVE WITHOUT LOOSENING THE HEX NUT OR YOU WILL DAMAGE THE WATER HEATERBEYOND REPAIR. POSITION DRAIN VALVE TO THE OPPOSITE DIRECTION AND RETIGHTENHEX NUT.

FILL WATER HEATER WITH WATER AND

• CHECK FOR PLUMBING LEAKS.

A. Be sure the water heater drain valve is closed by turning

the handle clockwise ( _ ).

B. Open nearby HOT water faucets to allow air to vent from the water heater and pipes.

C. Open the water heater cold water supply shut-off valve you installed in Step 2.
