INSTALLATION requirements Removing the Old Water 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 2 and 5. FIGURE 5. 5.
Facts to Consider About the Location 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 water heater. This water heater is not for use in manufactured (mobile) homes or outdoor installation.
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 water heater by at least 3 inches (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 9.
combined space should be considered in making this determination. Each opening should have a minimum free area of one square inch per 1,000 Btu per hour (22 cm 2/ kW) of the total input rating of all gas utilization equipment in the confined space, but not less than 100 square inches (645 cm2). One opening should commence within 12 inches (30 cm) of the top and one commencing within 12 inches (30 cm) of the bottom of the enclosures. • Do not cover the instruction manual.
FIGURE 12. • When communicating with the outdoors through vertical ducts, each opening should have a minimum free area of 1 square inch per 4,000 BTU per hour (5.5 cm2/kW) of total input rating of all equipment in the enclosure, see Figure 12 on page 11. FIGURE 14. • Louvers and Grilles: In calculating free area, consideration should be given to the blocking effect of louvers, grilles or screens protecting openings. Screens used should not be smaller than 1/4 inch (6.4 mm) mesh.
Water Piping reducing valves, check valves, back flow preventers, etc. to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed. As water is heated, it expands (thermal expansion) and closed systems do not allow for the expansion of heated water. The water within the water heater tank expands as it is heated and increases the pressure of the water system.
Temperature-Pressure Relief Valve TYPICAL INSTALLATION This heater is provided with a properly certified combination temperature - pressure relief valve by the manufacturer. 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.
DANGER • Burn hazard. • Hot water discharge. • Keep clear of TemperaturePressure Relief Valve discharge outlet. The Temperature-Pressure Relief Valve must be manually operated at least twice 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.
Venting • 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. The legs will snap in the holes to give a tight fit. Secure the legs of the draft hood with the supplied draft hood brackets. • 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.
There must be: • A readily accessible manual shut off valve in the gas supply line serving the water heater, and • A sediment trap ahead of the gas control valve to help prevent dirt and foreign materials from entering gas control valve. • A flexible gas connector or a ground joint union between the shut off valve and control valve to permit servicing of the unit. Be sure to check all the gas piping for leaks before lighting the water heater. Use a soapy water solution, not a match or open flame.
A sediment trap should be installed as close to the inlet of the water heater as practical at the time of water heater installation. The sediment trap should be either a tee fitting with a capped nipple in the bottom outlet or other device recognized as an effective sediment trap. If a tee fitting is used, it should be installed in conformance with one of the methods of installation, shown in Figures 20 and 21. pound per square inch (3.5 kPa).
Temperature Regulation The thermostat of this water heater has been factory set at its lowest position (PILOT LIGHTING). It is adjustable and must be reset to the desired temperature setting to reduce the risk of scald injury. The mark ( ) indicative of approximately 120°F (49°C) is preferred starting point. Some states have a requirement for a lower setting. Due to the nature of the typical gas water heater, the water temperature in certain situations may vary up to 30°F (16.
SERVICE AND ADJUSTMENT Vent System Inspection Burner Inspection At least once a year a visual inspection should be made of the venting system. You should look for: Flood damage to a water heater may not be readily visible or immediately detectable. However, over a period of time a flooded water heater will create dangerous conditions which can cause DEATH, SERIOUS BODILY INJURY, OR PROPERTY DAMAGE. Contact a Sears Service Center to replace a flooded water heater.
Housekeeping Temperature-Pressure Relief Valve Operation Vacuum around base of water heater for dust, dirt, and lint on a regular basis. The temperature-pressure relief valve must be manually operated at least once a year. INSTALLED IN SUITABLE AREA: To insure sufficient ventilation and combustion air supply, proper clearances from the water heater must be maintained. See Facts to Consider About the Location section. Combustible materials such as clothing, cleaning materials, or flammable liquids, etc.
Draining 5. Open the water heater drain valve and allow all of the water to drain from the tank. Flush the tank with water as needed to remove sediment. 6. Close the drain valve, refill the tank, and restart the heater as directed in this manual. If the water heater is going to be shut down for an extended period, the drain valve should be left open. IMPORTANT: Condensation may occur when refilling the tank and should not be confused with a tank leak.
TROUBLESHOOTING GUIDE Start Up Conditions Thermal Expansion Water supply system may, because of such events as high line pressure, frequent cut-offs, and the effects of water hammer have installed devices such as pressure reducing valves, check valves, back flow preventers, etc., to control these types of problems. When these devices are not equipped with an internal by-pass, and no other measures are taken, the devices cause the water system to be closed.
• a sulfate reducing bacteria within the water heater. (This harmless bacteria is non-toxic to humans.) • Burning gas produces water vapor in water heaters, particularly high efficiency models where flue temperatures are lower. • an excess of active hydrogen in the tank. This is caused by the corrosion protective action of the anode. • Large amounts of hot water are used in a short time and the refill water in the tank is very cold.
Operational Conditions (Continued) Never use this water heater unless it is completely filled with 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, see Figure 27. Leakage Checkpoints A. Water at the draft hood is water vapor which has condensed out of the combustion products. This is caused by a problem in the vent. Contact the gas utility. B.
