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 appliance.
This water heater is not for use in manufactured (mobile) homes or outdoor installation.
Whether replacing an old water heater or putting the water heater in a new location, the following critical points must be observed:
1.Select a location indoors as close as practical to the vent terminal or location to which the water heater vent piping is going to be connected, and as centralized with the water piping system as possible.
2.Selected location must provide adequate clearances for servicing and proper operation of the water heater.
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. Such a drain pan must have a minimum length and width of at least 2" (5.1 cm) greater than the water heater dimensions and must be piped to an adequate drain. The pan must not restrict combustion air flow.
Water heater life depends upon water quality, water pressure and the environment in which the water heater is installed. Water heaters are sometimes installed in locations where leakage may result in property damage, even with the use of a drain pan piped to a drain. However, unanticipated damage can be reduced or prevented by a leak detector or water
•Sensors mounted in the drain pan that trigger an alarm or turn off the incoming water to the water heater when leakage is detected.
•Sensors mounted in the drain pan that turn off the water supply to the entire home when water is detected in the drain pan.
•Water supply
•Devices that will turn off the gas supply to a gas water heater while at the same time shutting off its water supply.
INSTALLATIONS INAREAS WHERE FLAMMABLE LIQUIDS (VAPORS) ARELIKELYTOBEPRESENTORSTORED(GARAGES,STORAGEAND UTILITYAREAS, 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 hot surface igniter or main burner. The resulting flashback and fire can cause death or serious burns to anyone in the area. This water heater is equipped with a FV sensor for detecting the presence of flammable vapors, see Figure 9. When the sensor detects those vapors, the unit will shut down and not operate. Should this happen, please refer to the troubleshooting guide on pages
FIGURE9.
Also, the water heater must be located and/or protected so it is not subject to physical damage by a moving vehicle.
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" (7.6 cm) 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, 5" (12.7 cm) from the front
