Incorrect ambient conditions can lead to damage to the heating system and
put safe operation at risk. Ensure that the installation location adheres to the
information included in this manual. Failure to do so could result in property
damage, serious personal injury, or death.
Failure of water heater or components due to incorrect operating conditions
IS NOT covered by product warranty.
1. Installation Area (Mechanical Room) Operating Conditions

Ensure ambient temperatures are higher than 32
o
F/0
o
C and lower than
104
o
F/40
o
C.

Avoid continuously high levels of humidity

Never close existing ventilation openings
The service life of the water heater’s exposed metallic surfaces, such as the junction box, is directly influenced by proximity to damp
and salty marine environments. In such areas, higher concentration levels of chlorides from sea spray coupled with relative humidity
can lead to degradation of water heater components.
This water heater is certified for indoor installations only. Do not install the water heater outdoors. Outdoor installations ARE NOT
covered by warranty. Failure to install this water heater indoors could result in substantial property damage, severe personal injury, or
death.
2. Check for nearby connections to:

System water piping

Electrical power
Choose a location for the water heater as centralized to the piping system as possible.
3. Check area around water heater. Remove any combustible materials, gasoline, and other flammable liquids.
This water heater must not be located near flammable liquids such as gasoline, butane, liquefied propane, adhesives, solvents, paint
thinners, etc., as the controls of this water heater could ignite these vapors and cause an explosion, resulting in property damage,
severe personal injury, or death.
4. If the water heater is to replace an existing water heater, check for and correct any existing system problems, such as:

System leaks

Location that could cause the system and water heater to freeze and leak.

Incorrectly-sized expansion tank
5.
All piping should be insulated. Additionally, place the water heater so that the drain, controls, and inlets/outlets are easily accessible.
If you do not provide the minimum clearances shown, it might not be possible to service the heater without removing it from the space.
NOTE: When installing in a zero clearance location, it may not be possible to read or view some product labeling. It is recommended to
make note of the water heater model and serial number.
6. This water heater must be installed vertical on a level surface.
