necessary, raise thermostat setting to cause heater
to fire).
3. Press and hold for 5 seconds: "Pool On" (in Pool
mode) or "Spa On" (in Spa mode).
4. A new Control Board will show the stack flue tem-
perature. An old Control board will continue to
show the water temperature.
5. Refer to the chart below for the correct
Sensor/Probe to use with your heater's control
board. Purchase sensor or probe separately.

1. Turn off the filter pump and all electrical power to
the heater.
2. Allow the heater to cool for at least half an hour
before proceeding.
3. Unbolt and remove the Upper Left and Upper
Right Jackets from the heater.
4. Remove the 3/8-24 plug from the side of the Metal
Elbow Assembly.
5. Apply UltraCopper
®
the sealing faces of the Probe and its nut and
install the Probe in the 3/8"hole in the Metal
Elbow (Figure 4-9).
N N N N O O O O T T T T E E E E : : : : If the heater has a plastic Exhaust Elbow, DO
NOT PROCEED FARTHER with this installation. Instead,
call Customer Service at 1-800-752-0183 and order a Vent
Body Retrofit Kit (See Page 4-38) and replace the plastic
elbow with a metal one.

* RTV Silicone (supplied) to
Figure 4-9: Apply 600°F RTV to sealing faces of
probe and nut and install probe.
6. Apply UltraCopper
face of the nut and tighten it onto the Probe from
inside the Metal Elbow.
N N N N O O O O T T T T E E E E : : : : You have about 1/2 hour of working time
after spreading the RTV. After the joint starts to
cure, wait one hour before testing.
7. Connect the Stack Flue Switch wires to the new
Probe. Do not remove the stack flue switch; it is
sealed to the Combustion Chamber Flue Collar to
prevent carbon monoxide/flue gas leaks.
8. After one hour, fire heater for not more than one
minute to test for exhaust leaks. Reseal any leaks
that are found.
9. Reinstall the Upper Left and Upper Right Jackets
on the heater.
