3G. Seasonal Care
3G-1. Spring and Fall Operation
During periods when the pool is only going to be used once in a while, turn the temperature control to the "MIN" setting. This prevents the pool from becoming "chilled," yet still requires the least amount of time to raise the water back up to swimming temperature.
If the heater is not going to be used for a long period of time, shut it down completely, following the instructions in Section
3G-2. Winterizing
If you don't plan to use the pool or spa over the winter and your area is subject to freezing temperatures, have a qualified professional technician perform the following steps to protect the heater:
1.Shut off the heater's gas valve according to the lighting and shutdown instructions.
2.Shut off the main supply gas cock outside the heater jacket.
3.Completely drain the heater before the first frost. To drain the heater, remove the side panel, and remove the drain plug (see Figure 27).
4.Grease the threads of the drain plug and return it to the manifold, but do not tighten.
5.Disconnect the copper tubing from the pressure switch fitting (see Figure 27).
6.Cover the vent grille so that snow will not accumulate in the combustion blower, where it may freeze.
To reactivate the heater in the spring, have a qualified professional technician reassemble the heater as follows:
1.Attach the pressure switch fitting to the copper tubing (see Figure 27).
2.Tighten the drain plugs in the headers.
3.Clean the condensate drainage system and condensate trap.
4.Replace the combustion air filter.
5.Uncover the vent grille.
6.Turn on the main supply gas cock outside the heater jacket.
7.Turn on the heater according to the lighting and shutdown instructions inside the top cover.

1.Keep the top of the heater clear of all debris, and make sure there is no collecting of flammable materials, leaves, paper, etc., around or beneath the heater.
2.Keep the pool heater area clean and free of all combustible materials, gasoline and other liquids, and vapors.
3.Do not use the heater if any part has been under water. Immediately call a qualified professional technician to inspect the heater and replace any part of the control system and any gas control which has been under water.
4.Check for spider webs and other debris at the combustion air inlet and vent outlet — especially at spring start up.
