5 ABOUT YOUR WATER HEATER MODEL TYPE Congratulations for choosing a Solahart ® water heater. Your Solahart Streamline closed circuit solar water heater is designed for the solar collectors to be roof mounted and the solar storage tank to be installed at ground or floor level.
ABOUT YOUR WATER HEATER 6 SAFETY This water heater is supplied wi th temperature sensor s, a FlameSafe™ prot ection system, pressure relief valves and a combination temperature pressure reli ef valve. These devices must not be tampered with or removed.
ABOUT YOUR WATER HEATER 7 TO TURN ON THE WATER HEATER • Screw in the drain pl ugs at the cold water inlet a nd hot water outlet of the gas booster if the gas booster has been drained. • Open the cold water isolation valve fu lly at the inlet to the water heater.
ABOUT YOUR WATER HEATER 8 DOES THE WATER QUALITY AFFECT THE WATER HEATER? The water heater is suitable for most public wate r supplies, however some water q ualities may have detrimental effects on the cylinder, ga s booster heat excha nger and fittings.
ABOUT YOUR WATER HEATER 9 DRAINING THE GAS BOOSTER WATER HEATER • Turn off the water heater (refer to “Turn Off The Water Heater” on page 6). • Open a hot tap (preferably the shower outlet). • Unscrew the two drain plugs, one each at the cold water inlet and hot water outlet, on the underside of the water heater.
10 HOW YOUR WATER HEATER WORKS SOLAR OPERATION The Solahart Streamline closed circuit solar water he ater has its vitreous enamel lined solar storage tank installed at ground or floor level, remotely from the solar collectors. This water heater is an indirect solar hot water system with a heat exchanger in the solar storage tank.
HOW YOUR WATER HEATER WORKS 11 MAINS PRESSURE The water heater is designed to op erate at mains pressure by connec ting directly to the mains water supply. If the mains supply pressu re in your area exceeds that shown on page 19, a pr essure limiting valve must be fitted.
12 REGULAR CARE TEMPERATURE PRESSURE RELIEF VALVE This valve is near the top of the wa ter 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 approxim ately 1/50 of its volume.
13 SAVE A SERVICE CALL Check the items below before making a service call. You will be charged for attending t o any condition or fault that is not related to manufacture or failure of a part. COLD WATER FROM THE HOT TAP • Close the hot tap, wait 10 seconds and open the hot tap again.
SAVE A SERVICE CALL 14 • Are you using more hot water than y ou think? Is one outlet (especially the shower) us ing more hot water than you think? Very often it is not realised the amou nt of hot water used, particu larly when showering. Carefully review the family’s hot water usage.
SAVE A SERVICE CALL 15 TEMPERATURE PRESSURE RELIEF VALVE RUNNING • Normal Operation It is normal and desirable this valve allows a small quantity of water to escape during the heat ing cycle. However, if it discharges more than a bucket full of water in 24 hours, there may be another problem.
SAVE A SERVICE CALL 16 CLOUDS OF WHITE ‘VAPOUR’ FROM THE FLUE TERMINAL During the heating cycle, it is not unusual to see water vapour clouds steaming from the flue terminal, particularly on cold da ys. This is normal operation of the gas booster.
17 INSTALLATION – SOLAR STORAGE TANK THIS WATER HEATER IS FOR OUTDOOR INSTALLATION ONLY. THIS WATER HEATER IS NOT SUITABLE FOR POOL HEATING.
