WARNING: The heater shall not be located in an area where water sprinklers, or other devices, may cause water
to spray through the cabinet louvers and into the heater. This could cause internal rusting or damage some electrical
components, and this would void the warranty.
WARNING: Do not install within 3 feet of a heat pump or an outdoor condensing unit. Strong air intake from these
equipment can disturb the combustion process and cause damage or personal injury.
For installations in Canada, pool heaters shall not be
installed with the top of the vent assembly within 10 feet
below, or to either side, of any opening into the building.
