INSTRUCTIONS FOR INSTALLATION 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 (behind outer door). 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.

This appliance has been design certified as complying with American National Standard/CSA Standard for water heaters and is considered suitable for: HOTTER WATER CAN SCALD: Water heaters are intended to produce hot water. Water heated to a temperature which will satisfy space heating, clothes washing, dish washing, and other sanitizing needs can scald and permanently injure you upon contact.
LOCATING THE NEW WATER HEATER Facts to Consider About the Location • Devices that will turn off the gas supply to a gas water heater while at the same time shutting off its water supply. 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 appliance. This water heater is not for use in manufactured (mobile) homes or outdoor installation.
If this water heater will be used in beauty shops, barber shops, cleaning establishments, or self-service laundries with dry cleaning equipment, it is imperative that the water heater or water heaters be installed so that combustion and ventilation air be taken from outside these areas. Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.
top and one commencing within 12 inches (30 cm) from the bottom of the enclosure. The openings shall communicate directly, or by ducts, with the outdoors or spaces (crawl or attic) that freely communicate with the outdoors. Combustion Air and Ventilation for Appliances Located in Unconfined Spaces UNCONFINED SPACE is space whose volume is not less than 50 cubic feet per 1,000 Btu per hour (4.8 m3 per kW) of the aggregate input rating of all appliances installed in that space.
satisfies your hot water needs, a means such as a *mixing valve, shall be used at the hot water taps used by these people or at the water heater. Mixing valves are available at plumbing supply or hardware stores, see Figure 8 on page 9 and Figure 15 below. Valves for reducing point of use temperature by mixing cold and hot water are also available. Consult Maytag Customer Service (1-800-788-8899). Follow manufacturer’s instructions for installation of the valves.
• Look at the top of the water heater. The cold water inlet is marked “COLD”. Put two or three turns of teflon tape around the threaded end of the threaded-to-sweat coupling and around both ends of the 3/4” NPT threaded nipple. Using standard pipe fittings, connect the cold water pipe to the cold water inlet of the water heater. NOTE: This water heater is super insulated to minimize heat loss from the tank.
If replaced, the valve must meet the requirements of local codes, but not less than a combination temperature and pressure relief valve certified as indicated in the above paragraph. The Discharge Pipe: • Shall not be smaller in size than the outlet pipe size of the valve, or have any reducing couplings or other restrictions.
• 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. 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. • 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.
There must be a minimum of 6 inches (153 mm) clearance between single wall vent pipe and any combustible material. Fill and seal any clearance between single wall vent pipe and combustible material with mortar mix, cement, or other noncombustible substance. For other than single wall, follow vent pipe manufacturer’s clearance specifications. To insure a tight fit of the vent pipe in a brick chimney, seal around the vent pipe with mortar mix cement. plate is for the purpose of input adjustment.
Contaminants in the gas lines may cause improper operation of the gas control valve that may result in fire or explosion. Before attaching the gas line be sure that all gas pipe is clean on the inside. To trap any dirt or foreign material in the gas supply line, a drip leg (sometimes called a sediment trap) must be incorporated in the piping. The drip leg must be readily accessible. Install in accordance with the Gas Piping section. Refer to the current edition of the National Fuel Gas Code, ANSI Z223.
OPERATING INSTRUCTIONS FOR YOUR SAFETY READ BEFORE LIGHTING WARNING: If you do not follow these instructions exactly, a fire or explosion may result causing property damage, personal injury or loss of life. BEFORE OPERATING: ENTIRE SYSTEM MUST BE FILLED WITH WATER AND AIR PURGED FROM ALL LINES. A. This appliance has a pilot which must be lighted by hand. When lighting the pilot, follow these instructions exactly. • B. BEFORE LIGHTING smell all around the appliance area for gas.
installation of the valves. Before changing the factory setting on the thermostat, read the Temperature Regulation section in this manual, see Figures 22 and 23. Temperature Regulation Due to the nature of the typical gas water heater, the water temperature in certain situations may vary up to 30F° (16.7 C°) higher or lower at the point of use such as, bathtubs, showers, sink, etc. Never allow small children to use a hot water tap, or to draw their own bath water.
SERVICE AND MAINTENANCE Tank (Sediment) Cleaning Burner Inspection Sediment build-up on the tank bottom may create varying amount of noise, if left in the tank will cause permanent tank failure. In some water areas, sediment can be removed by draining off approximately one gallon of water each month. Flood damage to a water heater may not be readily visible or immediately detectable.
qualified technician. At a minimum, the anode(s) should be checked annually after the warranty period. The burner needs to be removed for cleaning. Call Maytag Customer Service at 1-800-788-8899 for an authorized servicer to remove and clean the burner and correct the problem that required the burner to be cleaned. Temperature-Pressure Relief Valve Operation Housekeeping The temperature-pressure relief valve must be manually operated at least once a year.
• Turn the gas control knob to the “OFF” position. • Remove the washer and put the new one in place. • CLOSE the cold water inlet valve to the water heater. • Screw the handle and cap assembly back into the drain valve and retighten using a wrench. DO NOT OVER TIGHTEN. • OPEN a nearby hot water faucet and leave open to allow for draining. • Follow instructions in the Filling The Water Heater section. • Connect a hose to the drain valve and terminate to an adequate drain. • Check for leaks.
Excessive condensation may be noticed during the winter and early spring months when incoming water temperatures are at their lowest. Operational Conditions Smelly Odor Good venting is essential for a gas fired water heater to operate properly as well as to carry away products of combustion and water vapor. In each water heater there is installed at least one anode rod (see parts section) for corrosion protection of the tank. Certain water conditions will cause a reaction between this rod and the water.
H. Combustion products contain water vapor which can condense on the cooler surfaces of the tank. Droplets form and drip onto the burner or run on the floor. This is common at the time of start-up after installation and when incoming water is cold. High Temperature Shut Off System This water heater is equipped with an automatic gas Shut-off system. This system works when high water temperatures are present. Turn “OFF” the entire gas supply to the water heater.
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. Inform the associate that this is a “Flammable Vapor Ignition Resistant” Product. Problem WATER LEAKS LEAKING T&P VALVE Cause Solution Improperly sealed, hot or cold supply connection, relief valve, drain valve, or thermostat threads. Leakage from other appliances or water lines. Condensation of flue products.
