8. Push the toggle switch away from you to switch the
gas on.
9. Replace the Door Access Panels. All panels must be
in place when operating the heater.
10. Set 3-way valves on inlet and outlet to pool or spa,
as appropriate.
11. Turn on all electric power to the appliance.
12. Press either the POOL ON or SPA ON button switch
on the operating control.
13. Set the thermostat to desired setting (NOTICE: Set
point must be above actual water temperature or
burner will not fire). See “OPERATING CONTROL.”
14. The blower should come on immediately, and after
about 20 seconds, the burner should fire. When
operating for the first time, the burner may not fire
on the first try because of air in the gas line. If it
does not fire at first, push the OFF switch, wait five
minutes, and again push the POOL or SPA ON switch.
The burner should fire after about 20 seconds. You
may have to repeat this until all of the air has cleared
the gas line.
15. The burner should fire until the pool/spa temperature
reaches the desired temperature set on the thermo-
stat. The blower will continue to run for about 45
seconds after the burner shuts off. If any of the
safety interlocks should open during burner opera-
tion, the burner shuts off immediately, but the blower
continues to run for about 45 seconds.
Should overheating occur or the gas supply fail to
shut off, turn off the manual gas control valve to the
appliance.

tions “TO SWITCH OFF GAS TO THE APPLIANCE”,

depressed, the digital display will indicate the tempera-
ture setting. After five seconds, the display will return to
the actual pool/spa temperature.
In addition to the digital temperature display, there are
five indicator lights:
The POOL ON light indicates that the pool water tem-
perature is governing operation of the heater.
The SPA ON light indicates that the spa water tempera-
ture is governing operation of the heater.
The HEATING light comes on and stays on when the
burner is firing. This light should be on whenever the
burner is on. It blinks when the heater is calling for heat
but not firing. If this light is on but the burner fails to
come on, one of the “service” lights should come on,
indicating a fault in the system.
