Choosing Installation Site
* Locate the appliance in an area where leakage from the unit or connections will not result in damage
to the area adjacent to the appliance or to the lower floors of the structure. When such locations
cannot be avoided, it is recommended that a suitable drain pan, adequately drained, be installed
under the appliance. The pan must not restrict combustion air flow.
• Locate the vent terminal so that there are no obstacles around the termination and so that ex-
haust can't accumulate. Do not enclose the termination with corrugated metal or other materials.
• Avoid places where fires are common, such as those where gasoline,
benzene and adhesives are handled, or places in which corrosive gases
(ammonia, chlorine, sulfur, ethylene compounds, acids) are present.
Using the incorrect voltage may result in fire or cracking.
• Avoid installation in places where dust or debris will accumulate.
Dust may block the air-supply opening, causing the performance of the
device fan to drop and incomplete combustion to occur as a result.
• Avoid installation in places where special chemical agents
(e.g., hair spray or spray detergent) are used.
Ignition failures and malfunction may occur as a result.
• Carbon Monoxide Poisoning Hazard. Do not install this water heater in a
recreational vehicle or on a boat.
• The water heater is designed for indoor installation only. Never install it
outdoors or in a bathroom, it may be damaged or a fire may be caused.
• Consult with the customer concerning the location of installation.
• Install the water heater in an area that allows for the proper clearances
to combustible and noncombustible construction. Consult the rating
plate on the appliance for proper clearances.
• Do not install the water heater in a place where it may be threatened by
falling objects, such as under shelves.
• The water heater must be installed in a place where supply and exhaust
pipes can be installed as directed.
• Do not install the water heater where the exhaust will blow on outer
walls or material not resistant to heat. Also consider the surrounding
trees and animals.
The heat and moisture from the water heater may cause discoloration of
walls and resinous materials, or corrosion of aluminum materials.
