F. Before operating the appliance for the first time or after it has been off for an extended time,
perform the following checklist:
1. Remove debris or other articles from inside the heater and the area around the heater and
its exhaust vent. Make sure the ventilation openings are clear of debris or obstruction. For
installations in an enclosed space, make sure openings for combustion and ventilation
air are unobstructed.
2. Keep heater area clear and free from combustibles, flammable liquids and chemicals.
3. Check that all water connections are tight.
4. Water must be flowing through the heater during operation. Make sure that pool/spa is
filled with water and have pump operating. Check that water flow is unobstructed from
the appliance. When operating for the first time or after an extended shut-down, run filter
pump for several minutes to clear all air from the system.
OPERATING INSTRUCTIONS
1. STOP! Read the safety information on (page 34).
2. Set both pool and spa thermostats to the lowest
settings.
3. Turn off all electric power to the appliance.
4. This appliance does not have a pilot. It is equipped
with an ignition device which automatically lights
the burner. Do not try to light the burner by hand.
5. Turn off the outside external manual shut-off gas
valve, see Figure 27.
6. Wait five (5) minutes to clear out any gas. If you then smell gas, STOP! Follow “B” in the
“Before Start-up” instructions (page 34). If you don’t smell gas, go to the next step.
7. Turn on the outside external manual shut-off gas valve, see Figure 27.
8. Set 3-way valves on inlet and outlet to pool or spa, as appropriate.
9. Turn on all electric power to the appliance.
10. Press either the POOL ON or SPA ON button switch on the operating control.
11. Set the thermostat to desired setting (NOTICE: Setpoint must be above actual water
temperature or burner will not fire). See “OPERATING the CONTROL PANEL”.
12. 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.
13. The burner should fire until the pool/spa temperature reaches the desired temperature set
on the thermostat. 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 operation, 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.
