• 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.

stagnant air.
• Consult with the customer concerning the location of installation.
• Do not install the water heater near staircases or emergency exits.
• 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.
• Do not locate the vent termination directed towards a window or any
other structure which has glass or wired glass facing the termination.
• Install in a location where the exhaust gas flow will not be affected by
fans or range hoods.
• Take care that noise and exhaust gas will not affect neighbors.
Avoid installation on common walls as the unit will make some
operational noises while it is running.
• Avoid installation where the unit will be exposed to excessive winds.
• Before installing, make sure that the vent termination will have the proper
clearances according to the National Fuel Gas Code (ANSI Z223.1).
