fired. Models with NA or HD suffix use natural gas only.
Models with LP suffix use propane (LPG) gas only. Do
not try to operate heater on any fuel except the fuel for
which it was designed. Improper installation, operation,
or servicing can cause gas leaks, fire, and explosion.

attempting to install or service this Sta-Rite Pool/Spa

Heater.

Use the section review questions to check your knowl-

edge of the heater and its operation.

Code (NEC) (ANSI/NFPA70) or Canadian

Electrical Code (CEC, Standard CSA 22.1) require-

• United States heater installations (including vent-

ing) must meet National Fuel Gas Code (ANSI

Z223.1) requirements and any local Fuel Gas Code

requirements or restrictions that apply.
