REMO VING THE OLD W ATER HEA TER REMOVING WA HEATER 4. Attach a hose to the water heater drain valve and put the other end in a floor drain or outdoors. Open the water heater drain valve. Open a nearby hot water faucet which will relieve pressure in the water heater and speed draining. The water passing out of the drain valve may be extremely hot. To avoid being scalded, make sure all connections are tight and that the water flow is directed away from any person, see Figures 3 and 6. FIGURE 6. 5.
MA TERIALS AND BASIC T OOLS NEEDED MATERIALS TOOLS DECIDING ON THE TYPE OF INSTALLATION Section B Copper (Sweat) Piping There are typically two different types of installations. The installation section of this manual has been broken into these two methods: The original piping is copper sweat and you are going to reconnect with sweat joints. Look at your old water heater installation to determine which type of installation you have.
LOCA TING THE NEW W ATER HEA TER OCATING WA HEATER FACTS TO CONSIDER ABOUT THE LOCATION • Water supply shut-off devices that activate based on the water pressure differential between the cold water and hot water pipes connected to the water heater. Carefully choose an indoor location for the new water heater, because the placement is a very important consideration for the safety of the occupants in the building and for the most economical use of the appliance.
This water heater must not be installed directly on carpeting. Carpeting must be protected by metal or wood panel beneath the appliance extending beyond the full width and depth of the appliance by at least 3” (76.2 mm) in any direction, or if the appliance is installed in an alcove or closet, the entire floor must be covered by the panel. Failure to heed this warning may result in a fire hazard. FIGURE 10.

One opening shall commence within 12” (30 cm) of the top and one commencing within 12” (30 cm) of the bottom of the enclosures. Insulation blankets are available to the general public for external use on gas water heaters but are not necessary with Reliance products.
a design of louver or grille is known, it should be used in calculating the size opening required to provide the free area specified. If the design and free area is not known, it may be assumed that wood louvers will be 20-25 percent free area and metal louvers and grilles will have 60-75 percent free area. Louvers and grilles shall be fixed in the open position or interlocked with the equipment so that they are opened automatically during equipment operation. FIGURE 13. 3.
INST ALLING THE NEW W ATER HEA TER INSTALLING WA HEATER FIGURE 16A. 3. Place the vent pipe over the draft hood. With the vent pipe in position, drill a small hole through both the vent pipe and draft hood. Secure them together with a sheet metal screw. 4. Wrap the 1” NPT threaded nipples (75 gallon models) or 1.25” NPT threaded nipples (100 gallon models) with teflon tape or pipe joint compound, see Figure 17. Connect the existing piping to the water heater. FIGURE 15.
8. After checking that all connections are tight and the drain valve near the bottom of the water heater is closed, go to “Filling the Water Heater”. FIGURE 20. SECTION B COPPER (SWEAT) PIPING (See Figure 19) FIGURE 20A. 3. Place the vent pipe over the draft hood. With the vent pipe in position, drill a small hole through both the vent pipe and draft hood.

shown. Clean the inside of each sweat fitting with the wire brush as shown. Make sure you do not touch the cleaned areas, see Figure 22. Flux the ends of the length of pipe cut for the T & P line and the inside of the 3/4” male threaded to sweat connector. Then solder this assembly together. Do not screw the connector into the Temperature-Pressure Relief Valve before the assembly is soldered together, see Figure 25. 13.
TEMPERATURE-PRESSURE RELIEF VALVE This heater is provided with a properly certified combination temperature - pressure relief valve by the manufacturer. FIGURE 27. The valve is certified by a nationally recognized testing laboratory that maintains periodic inspection of production of listed equipment of materials as meeting the requirements for Relief Valves for Hot Water Supply Systems, ANSI Z21.22•CSA 4.4 and the code requirements of ASME.
The temperature-pressure relief valve must be manually operated at least once a year. Caution should be taken to ensure that (1) no one is in front of or around the outlet of the temperature-pressure relief valve discharge line, and (2) the water manually discharged will not cause any bodily injury or property damage because the water may be extremely hot. actuated vent dampers). Before installation of any vent damper, consult the local gas utility for further information.
FIGURE 28. There must be a minimum of 6” (153 mm) clearance between single wall vent pipe and any combustible material. Fill and seal any clearance between single wall vent pipe and combustible material with mortar mix, cement, or other noncombustible substance. For other than single wall, follow vent pipe manufacturer’s clearance specifications. To insure a tight fit of the vent pipe in a brick chimney, seal around the vent pipe with mortar mix cement.
