Checklist to Determine Installation
Location
□ The water heater is not exposed to corrosive
compounds in the air.
□ The water heater location complies with the
clearances.
□ The planned exhaust outlet/air intake location
meets the clearances.
□ The water supply does not contain chemicals or
exceed total hardness that will damage the heat
exchanger.
□ A 120 VAC, 60 Hz source is available.
□ The installation must conform with local codes or,
in the absence of local codes, with the National
Fuel Gas Code, ANSI Z223.1/NFPA 54, or the
Natural Gas and Propane Installation Code, CSA
B149.1. If installed in a manufactured home, the
installation must conform with the Manufactured
Home Construction and Safety Standard, Title 24
CFR, Part 3280 and/or CAN/SCA Z240 MH Series,
Mobile Homes.
□ Leave the entire manual taped to the
temperature controller (if installed), or give the
entire manual directly to the consumer.

Freeze Protection

Make sure that in case of freezing weather that the
water heater and its water lines are protected to
prevent freezing. Damage due to freezing is not cov-
ered by the warranty.
Loss of freeze protection may result in water damage
from a burst heat exchanger or water lines.
With electrical power supplied, the water heater will
not freeze when the outside air temperature is as
cold as –4°F (-20°C) for outdoor models, when pro-
tected from direct wind exposure. Because of the
"wind-chill" effect, any wind or circulation of the air
on the unit will reduce its ability to freeze protect.
The unit may be drained manually. However, it is
highly recommended that:
•
drain down solenoid valves are installed that will
automatically drain the unit if power is lost.
These are available in a kit, 104000059.

In addition, the solenoid valves should be connected
electrically to a surge protector with terminals. This
allows the solenoid valves to operate if the water
heater is disabled due to a diagnostic code.
The freeze protection features will not prevent the
external piping from freezing. It is recommended that
hot and cold water pipes are insulated. Pipe cover
enclosures may be packed with insulation for added
freeze protection.
In the event of a power failure at temperatures below
freezing the water heater should be drained of all
water to prevent freezing damage. In addition, drain
the condensate trap and drain line.

Mount to Wall

1. Identify the installation location and confirm that
the installation will meet all required clearances.
2. Securely attach the water heater to the wall using
any of the holes in the wall installation brackets
which are at the top and bottom of the water
heater. Ensure that the attachment strength is
sufficient to support the weight. Refer to the
weight of the water heater in the Specifications
section.
Use a leveling tool to ensure that the water
heater is level. Proper operation requires that
the water heater be level.
NOTE: The water heater should be installed in an
upright position. Do not install upside down or on its
side.
