High Altitude
NATURAL GAS (NG)
Appliances are normally derated when installed at high elevation. This is
not necessary with the JXi heater because it has a special venturi-type
combustion system which self-compensates for changes in barometric
pressure. Air flow through the blower inlet pulls the correct flow of gas into
the burner regardless of air density.
JXi heaters are CSA certified for elevations of up to 4,500 feet above sea
level. At elevations above 4,500 ft., the heater BTU output can be expected
to be reduced by 4% for every 1,000 feet over 4,500 feet above sea level.
LIQUID PROPANE (LP)
* Indoor installation is not recommended for liquid propane heaters.
**Adjustable water pressure switch factory set to 7 psi.
See section 5.3 for adjustment instructions.
Review Special Precautions for liquid propane heaters (Section 4.3)
Any changes to the heater, gas controls, gas valve, air orifice, gas orifices, wiring, or
improper installation may void the warranty. If change is required to any of the above;
contact your local Jandy distributor, visit www.jandy.com or call technical support at
800.822.7933.
†For gas pipe size requirements see Section 4
‡Value displayed is for operating (fired) pressure not static.
§ Use type B double-wall gas vent, per table 13.1(a) NFPA 54
