Chapter 3. – Safety Requirements
3-3. 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
required that a suitable drain pan, adequately drained, be installed under the appliance.
The pan must not restrict combustion air flow.
DANGER
Locate the vent terminal so that there are no obstacles around the termination and so that exhaust
can't accumulate. Do not enclose the termination with corrugated metal or other materials.
WARNING
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
mobile home, recreational vehicle or on a boat.
CAUTION
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.
