  • Page 4: Introduction

    It is with the above in mind that we at Solahart Industries Pty Ltd are confident that your purchase of the “STREAMLINE GAS” water heater will provide you reliable hot water with quality after sales service back up.

  • Page 5: About Your Water Heater

    To meet the requirements of the National Plumbing Standard the temperature of the stored water must not be below 60°C. Solahart recommends the thermostat is set at 60°C to maximise solar contribution. HOTTER WATER INCREASES THE RISK OF SCALD INJURY This water heater can deliver water at temperatures which can cause scalding.
  • Page 6 If the electrical conduit to the water heater is damaged, it must be replaced by an authorised person in order to avoid a hazard. Phone your nearest Solahart Dealer to arrange for an inspection. The warranty can become void if relief valves or other safety devices are tampered with or if the installation is not in accordance with these instructions.
  • Page 7 ABOUT YOUR WATER HEATER TO TURN OFF THE WATER HEATER If it is necessary to turn off the water heater: • Shut down the gas control (refer to “Close Down Procedure” on page 40). • Close the gas isolation valve at the inlet to the gas control. •...
  • Page 8 ABOUT YOUR WATER HEATER DOES THE WATER QUALITY AFFECT THE WATER HEATER? The water heater is suitable for most public water supplies, however some water qualities may have detrimental effects on the cylinder, solar collectors and fittings. If you are in a known harsh water area you must read page 44.
  • Page 9 ABOUT YOUR WATER HEATER FREEZE PROTECTION Although the system has a level of freeze protection, designed to guard the system from unexpected frost conditions, the system is not recommended for installation in areas subject to frost or freeze conditions. Freeze conditions occur below 6°C. The system has NO WARRANTY for freeze damage (refer to “Warranty Exclusions”...

  • Page 10: How Your Water Heater Works

    HOW YOUR WATER HEATER WORKS The Solahart Streamline system has its vitreous 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 insulated copper pipe to the solar storage tank.

  • Page 11: Regular Care

    SERVICING For safe and efficient operation, the water heater should be serviced annually by your nearest Solahart Dealer. Only genuine replacement parts should be used on this water heater. Warning: Servicing of a gas water heater should only be carried out by authorised personnel.
  • Page 12 REGULAR CARE COLLECTOR GLASS Ensure the glass on your solar collectors is free of dust, salt spray or any other matter, which may reduce the effectiveness of the solar collectors. If the collector glass becomes dirty, hose down or if the solar collectors are accessible, wash the collector glass with water and a soft brush when the solar collectors are cool.

  • Page 13: Timer Operation

    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.
  • Page 14 TIMER OPERATION RECOMMENDED TIMER ON/OFF SETTING It is recommended the timer be set to enable boosting between 4:00 PM (16:00 Hours) and 6:30 PM (18:30 Hours). Note: The timer uses a 24 hour clock. This two and a half hour boosting period is sufficient to allow the gas burner to heat up the entire contents of the solar storage tank through a 45°C temperature rise.
  • Page 15 TIMER OPERATION TO SET ON/OFF TIMES To set “ON” time • MO TU WE TH FR SA SU Press and release the “PROG” button TIMER 16:00 If the timer has been reset, then “TIMER – ON”, “– – : – –” and “MO TU WE TH FR SA SU” will be displayed on the screen.
  • Page 16 TIMER OPERATION Note: If the timer is not set with an ON-OFF period, the solar water heater will not boost automatically. If the “MAN” button is pressed to activate the manual boosting “OVERRIDE” function and an ON-OFF period has not been set, the solar water heater will remain in boosting mode until the “MAN” button is pressed again to deactivate the manual boosting “OVERRIDE”...

    • Collector area is too small For most installations, the number of solar collectors recommended in Solahart literature has been proven to provide the required solar energy to meet the average family needs. However, in some circumstances, it may be necessary to install an additional solar collector.

    Check the water heater is suitable for the gas type available. (refer to the rating label on the water heater) The system can be installed with Solahart ‘L’ solar collectors. Although the system has a level of freeze protection, designed to guard the system from unexpected frost conditions, the system is not recommended for installation in areas subject to frost or freeze conditions.
  • Page 22 INSTALLATION – SOLAR STORAGE TANK As a guide the following requirements extracted from the Australian Gas Installations Standard AS 5601, must be observed: • At least 300 mm between the top of the solar storage tank and the eaves. • At least 500 mm between the solar storage tank and the edge of any opening into the building, measured horizontally and vertically.
  • Page 23 INSTALLATION – SOLAR STORAGE TANK TANK WATER SUPPLY If the water heater is supplied with water from a tank supply and a minimum water supply pressure of 200 kPa at the water heater cannot be achieved, then a pressure pump system must be installed to allow the solar circuit system to operate.
  • Page 24 INSTALLATION – SOLAR STORAGE TANK If a pressure limiting valve is installed on the cold water line to the solar water heater and the cold water line to a temperature limiting device branches off before this valve or from another cold water line in the premises, then a pressure limiting valve of an equal pressure setting may be required prior to the temperature limiting device.
  • Page 25 INSTALLATION – SOLAR STORAGE TANK REDUCING HEAT LOSSES The cold water line to and the hot water line from the water heater must be insulated in accordance with the requirements of AS/NZS 3500.4. The insulation must be weatherproof and UV resistant if exposed. The pipe work between the solar storage tank and the solar collectors must be fully insulated with closed cell polymer insulation or similar (minimum thickness 13 mm).

  • Page 32 CONNECTIONS – PLUMBING This water heater has either a plastic dip tube or fitting liner in the inlet and outlet fittings (see diagram). These must be in place for the water heater to function properly. Do not remove or damage them by using heat nearby. They will be pushed into the correct position as the fitting is screwed in.
  • Page 33 CONNECTIONS – PLUMBING BLEED VALVE DRAIN A copper drain line must be fitted to the bleed valve to carry the discharge clear of the water heater and solar controls. Connect the drain line to the bleed valve using a disconnection union. The pipe work from the bleed valve to the drain should be as short as possible and fall all the way from the valve with no restrictions.
