MAINTENANCE INSTRUCTIONS
It is recommended that you check the following items at least every six months and at the beginning of every swimming season.
1.Examine the venting system. Make sure there are no obstructions in the flow of combustion and ventila- tion air.
2.Visually inspect the main burner and the pilot burner flame. The normal color of the flame is blue. When flame appears yellow, burners should be inspected and cleaned; see Figure 10.
| Blue Flame |
| 3/8 to 1/2 in. |
| Insulated |
| Electrode |

3.Keep the heater area clear and free from combustibles and flammable liquids.
Relief Valve
In some installations, a relief valve is required on the MiniMax Plus.
Standard
Test the relief valve at least once a year by lifting the valve lever. (A.S.M.E. version varies slightly and has the relief valve

ENERGY SAVING TIPS
1.If possible, keep pool or spa covered when not in use. This will not only cut heating costs, but also keep dirt and debris from settling in the pool and conserve chemicals.
2.Reduce the pool thermostat setting to 78° F. or lower. This is accepted as being the most healthy temperature for swimming by the American Red Cross.
3.Use an accurate thermometer.
4.When the proper maximum thermostat settings have been determined, tighten the thermostat knob stopper.
5.Set time clock to start circulation system no earlier than daybreak. The swimming pool loses less heat at this time.
6.For pools that are only used on the weekends, it is not necessary to leave the thermostat set at 78° F. Lower the temperature to a range that can be achieved easily in one day. Generally, this would be 10° F. to 15° F., if pool heater is sized properly.
7.During the winter or while on vacation, turn the heater off.
8.Set up a regular program of preventative maintenance for the heater each new swimming season. Check heat exchanger, controls, burners, operation, etc.
SPRING AND FALL OPERATION
If the pool is being used occasionally, do not turn the heater completely off. Set the thermostat down to 65° F. This
will keep the pool and the surrounding ground warm enough to bring the pool up to a comfortable swimming temperature in a shorter period of time.
WINTER OPERATION
If the pool won't be used for a month or more, turn the heater off at the main gas valve. For areas where there is no danger of water freezing, water should circulate through the heater all year long, even though you are not heating your swimming pool. The MiniMax Plus should not be operated out doors at temperatures below 0° F. for propane and
possible, it is necessary to drain the water from the heater. This may be done by opening the drain valve located at the inlet/outlet header (see Figure 11.) allow- ing all water to drain out of the heater. It would be a good practice to use compressed air to blow the water out of the heat exchanger. (See additional notes under
