These include the elderly, children, the infirm, or physically/ mentally handicapped.
LOCATING THE NEW WATER HEATER Facts to Consider About the Location Installation of the water heater must be accomplished in such a manner that if the tank or any connections should leak, the flow will not cause damage to the structure. For this reason, it is not advisable to install the water heater in an attic or upper floor. When such locations cannot be avoided, a suitable drain pan should be installed under the water heater. Drain pans are available at your local hardware store.
INSTALLATIONS IN AREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARE LIKELY TO BE PRESENT OR STORED (GARAGES, STORAGE AND UTILITY AREAS, ETC.): Flammable liquids (such as gasoline, solvents, propane [LP or butane, etc.] and other substances such as adhesives, etc.) emit flammable vapors which can be ignited by a gas water heater’s pilot light or main burner. The resulting flashback and fire can cause death or serious burns to anyone in the area, as well as property damage.
• 24” minimum from any appliance inlet and/or outlet vents when directly below or 45 o to either side of center line, see Figure 13. • 12” minimum from the ground, 9” ceiling overhangs, see Figure 11. • 18” minimum in all directions from any obstruction that may interfere, see Figure 14. FIGURE 14. FIGURE 11. • The location selection must provide clearances for servicing and proper operation of the water heater, see Figure 15.
• Do inspect the insulation blanket frequently to make certain it does not sag, thereby obstructing combustion air flow. 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.
they connect. The minimum short side dimension of rectangular air ducts shall not be less than 3 inches (76.2 mm), see Figure 20. B. ALL AIR FROM OUTDOORS: (See Figures 18, 19 and 20) The confined space shall be provided with two permanent openings, one commencing within 12 inches (30 cm) of the top and one commencing within 12 inches (30 cm) from the bottom of the enclosure.
addition to using the lowest possible temperature setting that 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 21 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).
Secure all insulation using tape. must not be blocked or reduced in size under any circumstances. Excessive length, over 30 feet (9.14 m), or use of more than four elbows can cause restriction and reduce the discharge capacity of the valve, see Figure 24. No valve or other obstruction is to be placed between the relief valve and the tank. Do not connect tubing directly to discharge drain unless a 6 inch air gap is provided.
Wiring USE WITH POWER CORD The water heater comes equipped with a 7 foot power cord which can be used to connect to a 110/120 volt power source if, (1) local codes allow, and (2) there is a three prong grounded receptacle available. This unit must have a grounded outlet to operate. The temperature-pressure relief valve must be manually operated at least once a year.
USE WITHOUT POWER CORD If power cord cannot be used, then follow these wiring instructions. • Provide a way to easily shut off the electric power when working on the water heater. This could be with a circuit breaker or fuse block in the entrance box or a separate disconnect switch. • Install and connect a circuit directly from the main fuse or circuit breaker box. This circuit must be the right size and have its own fuse or circuit breaker.
Horizontal runs must be securely supported at 3 1/2” foot intervals and vertical runs supported at 5 foot intervals. Venting To insure proper venting of this gas-fired water heater, the correct vent pipe diameter must be utilized. Do not install other gas appliances on the same vent with this water heater as this will adversely affect the operation on the water heater. The combustion and ventilation air flow must not be obstructed. FIGURE 29.

Sediment Traps 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 Z223.1/NFPA 54.
OPERATING INSTRUCTIONS This water heater is equipped with an electronically operated venting system and electronic control. For the burner to come on, the water heater thermostat must call for heat. Then the system will begin sequencing, each section proving itself before gas is allowed to flow to the burner. 3. The venting manual reset switch must be in the closed position. See “Venting Manual Reset Switch” in the “Troubleshooting” section. 4.
Operating 5. Cycle is completed. CONTROL SEQUENCE - HOT SURFACE DIRECT IGNITION Propane gas is heavier than air. Should there be a leak in the system, the gas will settle near the ground. Basements, crawl spaces, skirted areas under manufactured (mobile) homes (even when ventilated), closets and areas below ground level will serve as pockets for the accumulated gas in the area. Search for odor of gas by sniffing at ground level in the vicinity of the appliance.

TROUBLESHOOTING Start Up Conditions Water supply system may, because of such events as high line pressure, frequent cut-offs, the effects of water hammer among others, 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.
hot water lines. Contact Maytag Customer Service at 1-800-788-8899 for further information concerning an Anode Replacement Kit and this Chlorination Treatment. If the smelly water persists after the anode replacement and chlorination treatment, we can only suggest that chlorination or aeration of the water supply be considered to eliminate the water problem. Do not remove the anode leaving the tank unprotected. By doing so, all warranty on the water heater tank is voided.
Leakage from other appliances, water lines, or ground seepage should also be checked. Leakage Checkpoints * To check where threaded portion enters tank, insert cotton swab between jacket opening and fitting. If cotton is wet, follow “Draining” instructions in the Periodic Maintenance section and then remove fitting. Put pipe dope or teflon tape on the threads and replace. Then follow Filling the Water Heater instructions in the Installation Instructions section. Read this manual first.
