Receiving equipment

The manufacturer recommends that this manual be
reviewed thoroughly before installing the pool/spa heater. If
there are any questions that this manual does not answer,
please contact the factory or your local representative.
On receipt of your equipment visually check for external
damage to the carton. If the carton is damaged, a note
should be made on the Bill of Lading when signing for
the equipment. Remove the heater from the carton. If it is
damaged, report the damage to the carrier immediately.
Save the carton.

Rating and certifications

These heaters are design-certified and tested under the
latest requirements of the ANSI Z21.56 / CSA 4.7 Standard
for Gas-Fired Pool Heaters. All heaters can be used either
indoor or outdoors when appropiate venting is installed.
The appropriate top designated for each type of use is
required. If necessary, the top can be changed at a later
date to change from outdoor to indoor or vice versa.
All brass header units have heat exchangers which are
ASME-certified (BPV Section IV part HLW) and are
registered with National Board.

Elevation

Rated inputs are suitable for up to 2,000 ft (610 m)
elevation. For elevations above 2,000 ft (610 m), reduce
input 4% for each 1,000 ft (305 m) above sea level, as high
elevation reduces combustion performance.
