Installation
Clean, Debris and Chemical-Free Combustion Air
Coastal Installations
Operating Temperature
The operation temperature is -22°F~140°F (-30°C~60°C), the anti-freeze module activates when
the ambient temperature is below 25°F (-4°C).
Follow the installation guidelines listed below regarding the air surrounding the unit and storage
of potentially dangerous items in the vicinity of the unit.
DO NOT
install the water heater in areas where dust and debris may accumulate.
DO NOT
install the unit where hair sprays, spray detergents, chlorine, or similar chemicals
are used.
DO NOT
install the water heater in areas where gasoline or other flammables are used or
stored.
DO NOT
allow hanging laundry or any similar items to obstruct access to the water heater or
its venting system.
Ensure that any combustible materials are properly and securely stored away from the
water heater.
Install the water heater near fixtures that deliver or use hot water, such as the bathroom, kitchen, and
laundry room faucets. Select a location that will minimize the amount of water piping required between the
major fixtures. Insulate as much of the hot water supply as possible. For more information regarding the
water supply, refer to Chapter 10.
Install the water heater in an area that will allow for service & maintenance as well as access to the utility
connections, piping, filters, and traps. Based on the installation location, ensure the clearances listed in the
table below are maintained.

NOTE
The combustion air must be free of flammable vapors or corrosive chemical fumes. Common
corrosive chemical fumes to avoid include: fluorocarbons, other halogenated compounds such as
freon, trichloroethylene, perchloroethylene, and chlorine, all of which can be found in
refrigerants or solvents. When these chemicals burn, they produce acids that can corrode the
stainless steel heat exchanger, gaskets, and the flue & venting system.
Proximity to Fixtures and Appliances
For installations in sea or marine environments, the salty air can cause corrosion to the water heater. The
water heater should be protected and enclosed to minimize exposure to the corrosive atmosphere. Damage
caused by a corrosive environment is not covered under the warranty.
The ambient temperature at the installation location must be above freezing. Steps should be taken to
ensure the water supply pipe line will not freeze.
