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.
As with any water heating appliance, the potential for leakage at some time in the life of the product does exist.
The manufacturer will not be responsible for any water damage that may occur.
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.
The manufacturer does not recommend installing the water heater in an attic due to safety issues.
If you install the water heater in an attic:
• Make sure the unit will have enough combustion air and proper ventilation.
• Keep the area around the water heater clean. Dust may accumulate and reduce the performance of
the unit's fan. This can result in incomplete combustion.
• Place the unit for easy access for service and maintenance.
• A drain pan, or other means of protection against water damage, is required to be installed under
the water heater in case of leaks.
CAUTION
Never draw combustion air from 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
