Many safety-related messages and instructions have been provided in this manual and on your own water heater to warn you and others of a potential injury hazard. Read and obey all safety messages and instructions throughout this manual. [. . . ] Water must flow from the hot water faucet before turning "ON" gas to the water heater. To fill the water heater with water: · Close the water heater drain valve by turning the handle to the right (clockwise). NOTE: The cold water supply valve must be left open when the water heater is in use. · To insure complete filling of the tank, allow air to exit by opening the nearest hot water faucet. Repair as needed. To insure proper venting of this gas-fired water heater, the correct vent pipe diameter must be utilized. Any additions or deletions of other gas appliances on a common vent with this water heater may adversely affect the operation of the water heater. Consult your Maytag Customer Service Center at 1-800-788-8899 or gas supplier if any such changes are planned. For proper venting in certain installations, a larger diameter vent pipe may be necessary. Consult your Maytag Customer Service Center at 1-800-788-8899 or gas supplier to aid you in determining the proper venting for your water heater from the vent tables in the current edition of the National Fuel Gas Code ANSI Z223. 1/NFPA 54. Periodically check the venting system for signs of obstruction or deterioration and replace if needed. The water heater with draft hood installed must be connected to a chimney or listed vent pipe system, which terminates to the outdoors. Never operate the water heater unless it is vented to the outdoors and has adequate air supply to avoid risks of improper operation, explosion or asphyxiation. · For proper draft hood attachment, the draft hood legs may be angled slightly inward. · Place the draft hood legs in the receiving holes on the top of the water heater. With the vent pipe in position, drill a small hole through both the vent pipe and draft hood. Obstructed or deteriorated vent systems may present serious health risk or asphyxiation. Venting VENT DAMPERS - Any vent damper, whether it is operated thermally or otherwise must be removed if its use inhibits proper drafting of the water heater. Thermally Operated Vent Dampers: This gas-fired water heater has a thermal efficiency at or above 80% which may produce a relatively low flue gas temperature. Such temperatures may not be high enough to properly open thermally operated vent dampers. This would cause spillage of the flue gases and may cause carbon monoxide poisoning. Vent dampers must bear evidence of certification as complying with the current edition of the American National Standard ANSI Z21. 66/CGA 6. 14, (covering electrically and mechanically actuated vent dampers). Before installation of any vent damper, consult your Maytag Customer Service Center at 1-800-7888899 or the local gas supplier for further information. FIGURE 18. The vent pipe from the water heater must be no less than the diameter of the draft hood outlet on the water heater and must slope upward at least 1/4 inch per linear foot (21 mm per meter), see Figure 19. FIGURE 19. 16 All vent gases must be completely vented to the outdoors of the structure (dwelling). Install only the draft hood provided with the new water heater and no other draft hood. [. . . ] Combustion products contain water vapor which can condense on the cooler surfaces of the tank. This is common FIGURE 28. 26 TROUBLESHOOTING GUIDE These guidelines should be used by a qualified Maytag Customer Service Center Agent. Call the Maytag Customer Service Center at 1-800-788-8899 for assistance. Problem Cause Improperly sealed, hot or cold supply connection, relief valve, drain valve, or thermostat threads. High sulfate or mineral content in water supply. Solution Tighten threaded connections. [. . . ]
