A . 184382-001 SAFE INSTALLATION, USE AND SERVICE Your safety and the safety of others is extremely important in the installation, use and servicing of this water heater. 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. [. . . ] · Shall not have any valve between the relief valve and tank. 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. If after manually operating the valve, it fails to completely reset and continues to release water, immediately close the cold water inlet to the water heater, follow the draining instructions, and replace the temperature-pressure relief valve with a new one. Filling the Water Heater FIGURE 17. Never use this water heater unless it is completely full of water. 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). The drain valve is on the lower front of the water heater. 15 · Open the cold water supply valve to the water heater. 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. 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: Gas-fired water heaters having thermal efficiency in excess of 80% 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. 68 (ANSI Z21. 66 & 67, respectively, cover electrically and mechanically actuated vent dampers). Before installation of any vent damper, consult your Maytag Customer Service Center at 1-800-788-8899 or the local gas supplier for further information. For replacement heater installations where using pre-existing venting, venting must be inspected for obstructions and if deterioration is present venting must be replaced. 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. To insure proper venting of this gas-fired water heater, the correct vent pipe diameter must be utilized. [. . . ] Call the Maytag Customer Service Center at 1-800-788-8899 for assistance.
