Outdoor Installation Location

1. Outdoor Installation Area Operating Conditions.

• Ensure ambient temperatures are higher than 5

°F

/-15

°C

• Prevent the air from becoming contaminated by the products, places, and conditions listed in the

water heater installation manual.

WARNING

Carefully consider installation when determining water heater location. Please read the entire installation

manual and these instructions before attempting installation. Failure to properly take factors such as piping,

condensate removal, venting, and wiring into account before installation could result in wasted time, money,

and possible property damage, personal injury, or death.

The outdoor kit is meant for use in outdoor installations ONLY. DO NOT install the water heater with

outdoor kit indoors. Installing the water heater with outdoor kit indoors will result in improper water heater

operation and property damage, and could result in serious personal injury or death.

WARNING

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 heater or components due to

incorrect operating conditions IS NOT covered by product warranty.

The water heater must be installed as described in these instructions: Upright, with the suppled outdoor

enclosure in the vertical position. DO NOT attempt to install the water heater in any other orientation. Failure

to follow these instructions will result in improper water heater operation and property damage, and could

result in serious personal injury or death.

2. Check for nearby connections to:

• System water piping

• Venting connections

• Gas supply piping

• Electrical power

• Condensate drain

Note:

The manufacturer reserves the right to make changes or updates

without notice and will not be held liable for errors in literature.

Install the water heater where any leakage from the relief valve, related piping, tank, or connections will not

result in damage to surrounding areas, lower oors of the building, or pool on the ground and freeze.

The water heater should be located near a drain or piped to a drain. Leakage damages ARE NOT covered

by warranty.

CAUTION

3. Check surroundings of water heater.

Remove any combustible materials, gasoline, and other ammable liquids.

WARNING

Failure to keep the water heater area clear and free of combustible materials, liquids, and vapors can result in

substantial property damage, severe personal injury, or death.

4. If the water heater is to replace an existing heater, check for and correct any existing system problems, such

as:

• System leaks

• Location that could cause the system and heater to freeze and leak

• Incorrectly sized expansion tank

5. Clean and ush system when reinstalling a heater.

Do not connect the water heater to any heating systems or components that have been previously used for

nonpotable applications. Do not introduce toxic chemicals, such as antifreeze or water heater treatments,

into the water heater or any piping meant for potable purposes. Ensure that all piping and components

connected to the water heater are suitable for potable water applications. Do not use this water heater for

space heating applications.

CAUTION

The

water heater must be installed level in order for the condensate to properly ow out the collection system.

from Non-Combustibles

Recommended Service

and Proper Operation

Clearances

Top of appliance 36 in (900mm)

Back of appliance 5/8 in (15.9mm)

Front of appliance 24 in (600mm) 24 in (600mm) or more

Side of appliance 3 in (75mm)

Bottom of appliance 12 in (304.8mm)

Note:

The outdoor enclosure for this appliance

is approved for zero clearance to

combustible construction.

If the water heater is installed in a

narrow space or corner ensure that there

is sufcient space for service.

In multiple water heater installations,

ensure a minimum clearance of 36" from

the top of one water heater to the bottom

of the next water heater, and a minimum

clearance of 3" from the side of water

heater to the next water heater.

WARNING

Do not locate the water heater where exposed to prevailing winds.

Moisture will be produced by the exhaust vent. Take precautions when determining water heater location.

Moisture may fall from the vent termination to the ground and turn to ice in freezing conditions. Moisture or

ice can produce a hazardous condition.

Exhaust condensate is acidic and could deteriorate the surface below the exhaust vent termination.

Ensure this surface is in good repair (sealed, painted, etc.) to prevent deterioration. Failure to follow these

instructions could result in substantial property damage, serious personal injury, or death.

Prevent Combustion Air Contamination

Do not install the outdoor water heater in locations that

can allow contamination of fresh intake air.

Note:

See Table 2 to prevent combustion air

contamination.

WARNING

Ensure that the intake air will not contain any of the contaminants in Table 2. Contaminated air will damage

the heater, resulting in possible substantial property damage, severe personal injury, or death. For example,

do not pipe intake air near a swimming pool or laundry facilities. These areas always contain contaminants.

Products to Avoid Areas Likely to Have Contaminants
