4. BEFORE INSTALLATION

4.1. 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 it is suggested that you
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.
These items are shipped inside a box in the carton with
the heater:
1. "Pagoda" top
2. In/Out flanges (2)
3. 2" CPVC female tailpiece, ring nut and O-ring
4. 2" flange gaskets (2)
5. Flange bolts (4)
6. Pressure relief valve
7. 2" CPVC adapter
8. Plastic pipe finish flange for gas line
9. Bonding lug with mounting screw
10. 2" CPVC manifold adapter
11. Prewired 1" flow switch with outdoor cover
12. Temperature and pressure gauge

Be sure that you receive the number of packages indicated
on the Bill of Lading.
When ordering parts, you must specify the model and
serial numbers of the heater. See below for location of
serial number. When ordering under warranty conditions,
you must also specify date of installation.

4.2. 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. 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 units have heat exchangers which are ASME-certified
(BPV Section IV part HLW) and are registered with
National Board.
4.3. Ambient Temperature Rating
of Heater Components
Electronic Ignition Heater* -32°F to + 175°F (-36°C to 79°C)
*Requires 120 or 240VAC Power Supply

4.4. Atmospheric heaters

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.

5. INSTALLATION

5.1. Installation Codes

Installation must be in accordance with local codes, or,
in the absence of local codes, with the latest edition of
the National Fuel Gas Code, ANSI Z223.1/NFPA54 and
National Electrical Code, ANSI/NFPA 70, and for Canada,
the latest edition of CAN/CSA-B149 Installation Codes,
and Canadian Electrical Code, CSA C22.1 Part 1 and
Part 2.
