PART 3 – PREPARE WATER HEATER LOCATION
Carefully consider installation when determining heater location. Please read the entire manual before attempting installation. Failure to
properly take factors such as heater venting, piping, condensate removal, and wiring into account before installation could result in
wasted time, money, and possible property damage and personal injury.
A. BEFORE LOCATING THE HEATER
These heaters are design certified for outdoor installations. Heaters must not be installed under an overhang unless clearances are in
accordance with local codes, the requirements of the gas supplier / utility, and the AHJ. Three sides must remain open in the area
under the overhang. Roof water drainage must be diverted away from heaters installed under overhangs. Failure of heater or
components due to incorrect operating conditions IS NOT covered by product warranty.
Incorrect ambient conditions can lead to damage to the heating system and put safe operation at risk. Ensure that the heater installation
location adheres to the information included in this manual. Failure to do so could result in property damage, serious personal injury, or
death.
The water heater is heavy. Take precautions when moving the water heater into its installation location to avoid tipping, bumping, or
dropping it. Failure to take such precautions may result in property damage, severe personal injury, or death.
Failure of heater or components due to incorrect operating conditions IS NOT covered by product warranty.


Prevent the air from becoming contaminated by the
products, places, and conditions listed in this manual,
Part 3, Section F.

Avoid continuously high levels of humidity

Never close existing ventilation openings

Ensure a minimum 1” clearance around hot water and
exhaust vent pipes
b. Outdoor Installation

Heater must be placed in an area where the exhaust
plume will not be recirculated into the louver system
located on the front access panel. Avoid fences or walls
that extend above the exhaust vent termination. Pipe the
exhaust vent so that it terminates level with or above the
fence, wall, or enclosed area.

Do not install heaters in locations where rain from
building runoff may spill onto the heater. Doing so could
result in premature product failure. Such failures ARE
NOT covered by warranty.

Do not locate where sprinklers may spray directly onto
the heater cabinet and possibly into the louvers, which
could damage the control system and internal
components of the water heater. Such damages ARE
NOT covered by warranty.

Do not install directly on the ground, as the water heater
is heavy when filled with water. Install the heater level on
a concrete pad, block, or pressure treated wood platform,
designed to support the weight of the water heater and
components when filled with water. The water heater
must be properly supported and installed level in order to operate and drain condensate properly.

Do not install the water heater under a deck or porch.
