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. If installation in such areas is your only option, then installation must be accomplished in a way that the pilot flame and main burner flame are elevated from the floor at least 18 inches. While this may reduce the chances of flammable vapors, from a floor spill being ignited, gasoline and other flammable substances should never be stored or used in the same room or area containing a gas water heater or other open flame or spark producing appliance. NOTE: Flammable vapors may be drawn by air currents from other areas of the structure to the appliance.

Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle.

Propellants of aerosol sprays and volatile compounds, (cleaners, chlorine based chemicals, refrigerants, etc.) in addition to being highly flammable in many cases, will also change to corrosive hydrochloric acid when exposed to the combustion products of the water heater. The results can be hazardous, and also cause product failure.

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 appliance 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.

Minimum clearances between the water heater and combustible construction are 0 inch at the sides and rear, 6 inches (152 mm) at the front, and 0 inches from the vent pipe. Clearance from the top of the jacket is 14 inches (356 mm) on most models. Note that a lesser dimension may be allowed on some models, refer to the label attached adjacent to the gas control valve on the water heater, see Figure 9.

•Do not obstruct water heater air intake with insulating blanket.

•Gas and carbon monoxide detectors are available.

•Install water heater in accordance with the instruction manual.

A gas water heater cannot operate properly without the correct amount of air for combustion. Do not install in a confined area such as a closet, unless you provide air as shown in the Locating The New Water Heater section. Never obstruct the flow of ventilation air. If you have any doubts or questions at all, call your gas supplier. Failure to provide the proper amount of combustion air can result in a fire or explosion and cause death, serious bodily injury, or property damage.

FIGURE10.

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.

Combustion Air and Ventilation

When determining the installation location for a power vent water heater, snow accumulation and drifting should be considered in areas where applicable.

HRN11240P, HRP11240P, HRN11275P, HRP11250P, HRP31275P specifications

The Maytag HRP31250P, HRN31275P, HRP31275P, HRP11240P, and HRP11275P are high-efficiency residential heat pumps designed to provide optimal comfort and energy savings for homeowners. These models showcase Maytag's commitment to reliability, durability, and advanced heating technology.

One of the standout features of the Maytag HRP series is its impressive SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings. These ratings indicate high efficiency, which translates to reduced energy bills and a smaller carbon footprint. The heat pumps operate efficiently in both heating and cooling modes, making them versatile for year-round climate control.

The HRP31250P and HRP31275P models include variable-speed compressors. This technology allows the heat pumps to adjust their output based on the heating or cooling demand. As a result, they maintain consistent indoor temperatures while using less energy. The variable-speed operation also means quieter operation compared to traditional single-stage units, making for a more pleasant home environment.

Additionally, the HRN31275P model stands out with its advanced inverter technology. This technology provides even greater efficiency by allowing the unit to operate at various capacity levels.
