MAINTENANCE INSTRUCTIONS

It is recommended that you check the following items at least every six months and at the beginning of every swimming season.

CAUTION

REMOVE THE FLOW VALVE ASSEMBLY WHEN DRILLING THE HOLE TO INSTALL A PRV. OTHERWISE, YOU WILL DRILL INTO THE VALVE ASSEMBLY.

1.Examine the venting system. Make sure there are no ob- structions in the flow of combustion and ventilation 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 8.

3.Keep the heater area clear and free from combustibles and flammable liquids.

Pressure Relief Valve

In some installations, a pressure relief valve (PRV) is required on the MiniMax CH heater. To install a PRV, carefully drill a 3/8 in. hole in center of 3/4 in. NPT port (on main header) being careful to drill only thru wall at bottom of 3/4 in. NPT port and no deeper—now thread

in the 3/4 NPT PRV. (Sold separately.)

FOR PRV INSTALLATION DRILL THRU THE NPT PORT

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

CAUTION

OPERATING THIS HEATER CONTINUOUSLY AT WATER TEMPERATURE BELOW 68° F. WILL CAUSE HARMFUL CONDENSATION AND WILL DAMAGE THE HEATER AND WILL VOID THE WARRANTY.

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 CH should not be operated out doors at temperatures below 0° F. for propane and -20° F. for natural gas. Where freezing is 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 9.) allowing 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 Important Notices in Introduction on page 3.)
