HOW YOUR WATER HEATER WORKS The Rheem solar Loline system has its vitr eous enamel lined solar storage tank installed at ground level, remotely from the solar collectors. As the sun heats the water in the solar collectors the increase in temperature activates the circulator. The circulator then moves the water from the solar collectors through an i[...]

HOW YOUR WATER HEATER WORKS 12 PIEZO IGNITION The “Piezo” push button igniter makes lighting the pilot flame of your water heater very easy. Simply follow the instructions on the label attached to the back of the access door. There is no need for matches to light the water heater. PILOT IGNITER A permanent pilot flame burns to ignite the main b[...]

REGULAR CARE TEMPERATURE PRESSURE REL IEF VALVE This valve is near the top of the water heater and is essential for its safe operation. It is possible for the valve to release a little water through the drain line during each heating period. This occurs as the water is heated and expands by approximately 1/50 of its volume. wat er heater drain line[...]

REGULAR CARE 14 EXPANSION CONTROL VALVE In many areas, including South Australia, Western Australia and scaling water areas, an expansion control valve is fitted to the cold water line to the water heater. The expansion control valve may discharge a small quantity of water from its drain line during the heating period instead of the temperature pre[...]

REGULAR CARE 15 FLUSHING THE SOLAR COLLECTORS It may be necessary to flush the solar collectors if there is sediment in the water supply. This should be conducted in th e morning, within three hours of sunrise, when the water temperature inside the solar collector(s) is lower. • Open a hot water tap and allow the water to run for five (5) minutes[...]

TIMER OPERATION FUNCTIONS OF THE TIMER The timer is an accurate, electronic device which allows up to six (6) ON-OFF periods to be set per day. It is recommended only one (1) period per day be programmed into the timer. This will be sufficient for most installations. The timer is not weatherproof and must be installed indoors. It is recom mended th[...]

TIMER OPERATION 17 The function of the timer is to enable the gas burner to automatically boost the stored water temperature, if required, due to low solar energy gain during the day. This will ensure the solar storage tank is full of hot water for the evening hot water requirements. Warning: The timer is not waterproof. Do not splash the timer wit[...]
