multiple water heater installations, ensure a minimum clearance of 32″ from
the top of one water heater to the bottom of the next water heater, and a
minimum clearance of 4″ from the side of the 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 the
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
hazardous conditions. 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 facility. These areas always
contain contaminants [ Table 2 ]
