Gas-Fired Pool & Spa Heater

Installation & Operation Manual
5.3 Plumbing Connections
The heater has a standard 2 inch water header and coupling
design. With this feature, only nominal two inch PVC
or CPVC may be connected to the heater. However, by
installing the appropriate pipe adapters and two (2) short
pieces of two-inch plastic pipe (supplied by the installer),
any size existing pipe may be fitted to the heater.
Optional Water Inlet Piping
The water inlet can be piped in one of two possible
configurations. The heater comes with a Zodiac
®
Sweep Elbow for increased hydraulic performance and
efficiency. The sweep elbow also provides the advantage
of its exclusive interface with the Zodiac AquaLink
®
RS
temperature sensor. The sweep elbow may be installed in
the top inlet connection, and the cap and plug with O-ring
installed to close off the unused side port (see Figure 15).
This configuration may be preferred for Versa Plumb
®
piping to mating components
