If the indoor <br />Installation ares is subject to freezing temperaturos. tho <br />water piping must be protected by insulalion. <br /> <br />Water supply pressure should not exceed 80% of the <br />working pressure of the water heater. The working <br />prossuro is stated on the water hester's data plate. It <br />this occurs a pressure limiting valve with s byPass may <br />need to be installed in the cold water supply line. This <br />should be placed on the supply to the entire house in <br />artier to maintain equal hot and cold water pressures. <br /> <br />Important: Heat cannot be applied to the water fittings <br />on the heater as they may contain nonmetallic parts. If <br />solder connections arc: used, solder the pipe to the <br />adapter before attaching the adapter to the hot and co.ld <br />water fittings. <br /> <br />Important: Always use a good grade of joint compound <br />and be certain that all fittings arc drawn up tight. <br /> <br />1. Install the water piping and tittings as shown in <br />Figure 2.. Conneet the cold water supply (3/4 NPT) <br />to the fitting marked "C.. Connect the hot water <br />supply (3/4 NPT) to the fitting marked "Ii". <br /> <br />Important: Some models may contain energy saving <br />heat traps to prevent the circulatfon of hot water within <br />the pipes. Do not relTlove these inserts. <br /> <br />2. The insrallatiotl of unions in both the hol and cold <br />water supply lines is recommended for ease of <br />removing the water heator for service or <br />replaccment <br /> <br />3. The manufacturer of this water heater recommends <br />installing a tefTlPering valve in the domestic hot <br />water line as shown in Figures 3 and 4. These <br />valves reduce tt.e point-af-use temperature of the <br />hot water by mixing cold and hot water and are <br />readily available. Contact a licensed plumber or the <br />local plumbing authority. <br /> <br />4. If installing the water heater in a closed water <br />system, install e relief valve or expansion tank in <br />the cold water line as specified under "Closed <br />SystcmfThemlal Expansion". <br /> <br />5. Install a shut-off valve in the cold water inlet line. It <br />should be iocalM ciose to the water healer and be <br />easily accessible. Know the location of this valve <br />and how to shut off the water to the heater. <br /> <br />6. Install a temperature and pressure relief valve and <br />d~chatge line in the opening markr.d "T & P <br />RELIEF VALV'e'.lnstsll as spedfied under <br />"Temperature and Pressure ReliefVslve." <br /> <br />7 - After piping has been properly connected to the <br />water heater. open the noarest hot water faucet and <br />allow the tank to completely fill with water. To purge <br />the lines of any excess air and sediment, keep the <br />hot water faucet open for 3 minutes sfter a constant <br />flow of water is obtained. Close the fsucet and <br />check all connections for Joaks. <br /> <br />Figure 2 <br />W.er Pipi"D 1n~"I"UOtI <br /> <br />/It. COIe.&ed System _.a <br />~ T".......I~si_T_. <br /> <br />P........,.
