Do NOT sanitize the pool by putting chlorine tablets or sticks into the skimmer(s). When the pump is off, this will cause a high concentration of chlorine to enter the heater, which could cause corrosion damage to the heat exchanger. WATER PRESSURE SWITCH WARNING Hazardous pressure. Do not bypass the Water Pressure Switch or render it inoperable. Switch Settings The water pressure switch turns off the burner if the water flow is interrupted. If the water flow is restricted, the water pressure switch may prevent the burner from firing and cause the “Service System” light to go on. If the light remains on after the filter has been serviced, have a qualified service technician check the system. For deck-level heater installations, the Pressure Switch is factory set at 3 psi (20.6 kPa). If the pressure switch is one to two feet (.3-.6M) below or one to five feet (.31.5M) above the pool water level, reset the switch so that it is open when the pump is off and closed when the pump is running. Turn the star-wheel on the switch clockwise ( ) to raise setting (heater below the pool) and counterclockwise ( ) to lower the setting (heater above the pool – see Figures 17 and 18). Test the switch after resetting. NOTICE: When the heater is mounted more than five feet (1.5M) above or two feet (.6M) below the deck level, a Pressure Switch is no longer adequate. A Flow Switch must be installed instead. NOTICE: Heater operation with incorrect Pressure Switch setting may cause operation with no water flow. Operation of the heater without sufficient water flow may severely damage it. 16 17 Verify proper operation of the water pressure switch at the start of every season and every six months thereafter by the following steps: 1. Lower the thermostat setting to turn off the heater. 2. Wait at least 15 minutes after the burner is off, and then turn off the filter pump. 3. Turn up the thermostat as though to fire the burner. 4. Wait one minute. The “Service System” light should go on but the burner should not fire and the blower should not start. If the blower or burner do start, or if the “Service System” light does not go on, there is a pressure switch malfunction. Immediately press the OFF button on the operating control to turn the burner off and call a qualified service technician to check the system. Live steam hazard. If the Burner and the Pump stop at the same time, wait at least 15 minutes before starting the filter pump to avoid severe damage to the heater.

Purchase separately and install a 3/4" pressure relief valve complying with the ANSI/ASME Boiler and Pressure Vessel Code, having a capacity equal to the Btu/hr rating of the heater. The relief pressure of the valve MUST NOT EXCEED 50 PSI. A 3/4" NPT connection is provided in the manifold for installing a pressure relief valve. The relief valve must be installed vertically. To install the valve, use a 3/4" brass nipple and elbow (user supplied), as illustrated in Figure 19. No valve is allowed to be placed between the manifold adapter and the relief valve. To avoid water damage or scalding from operation of the relief valve, install a drain pipe in the outlet of the pressure relief valve that will direct water discharging from the valve to a safe place for disposal. Do not install any reducing couplings or valves in the drain pipe. The drain pipe must be installed so as to allow complete drainage from the valve and drain line. The relief valve should be tested at least once a year by lifting the valve lever. Explosion hazard. Any heater installed with restrictive devices in the piping system downstream from the heater (including check valves, isolation valves, flow nozzles, or therapeutic pool valving) must have a relief valve installed as described above. WARNING Pipe relief valve discharge to a drain or other safe dispos...
