B. Heating a Pool or Spa
Please contact a local pool/spa specialist if this boiler is to be used to heat a pool or spa. A
stainless steel (or 90/10 copper/nickel alloy) tube & shell water-to-water heat exchanger must be
used to transfer heat from the boiler to a pool or spa since the chemicals used in a pool/spa are
destructive to the boiler. Pool heat exchangers are available from NC or your dealer. For sizing you
will need to know the volume of the pool in cubic feet or gallons. Be sure to install isolation and
bypass valves for easy servicing and winter draining and also place before a chlorinator. Install a
separate line and pump on the boiler that is controlled to only run when the pool filter pump runs.
