Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual. Never use this water heater unless it is completely full of water. To prevent damage to the tank, the tank must be filled with 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. • 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. Allow water to run until a constant flow is obtained. This will let air out of the water heater and the piping. • Check all water piping and connections for leaks. Repair as needed. VENT DAMPERS - Any vent damper, thermally or otherwise must be removed drafting of the water heater. whether it is operated if its use inhibits proper 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 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 gas supplier if any such changes are planned. For replacement heater installations where using preexisting venting, venting must be inspected for obstructions and if deterioration is present, venting must be replaced. For proper venting in certain installations, a larger diameter vent pipe may be necessary. Consult your local Sears Service Center 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 combustion and ventilation air flow must not be obstructed. 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, be angled slightly inward. the draft hood legs may Place the draft hood legs in the receiving holes on the top of the water heater. The legs will snap in the holes to give a tight fit. Secure two legs to top with sheet metal screws. 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. See Figure 18.
