INSTALLATION INFORMATION REGULATIONS AND OCCUPATIONAL HEALTH AND SAFETY (OH&S) Installation and commissioning must be performed by authorised persons. Rinnai solar systems must be installed in accordance with these instructions and all regulatory requirements which exist in your area including those in relation to manual lifting, working at heights and on roofs.
INSTALLATION INFORMATION WATER SUPPLY The minimum and maximum water pressures for the various systems are listed in Table 5. Approved pressure limiting valves may be required if the 'Maximum' rated water supply pressures are exceeded. For gas boosted systems to achieve the rated flow through the outlet of the continuous flow water heater, the minimum water supply pressures must be supplied. The systems will operate at lower pressures but the rated flow will not be achieved.
INSTALLATION INFORMATION VALVES AND FITTINGS Components Supplied by Installer The following valves & fittings are to be supplied by the installer: • A cold water expansion control valve (ECV). An ECV must be fitted in Western Australia and South Australia to the cold water supply to the storage cylinder to comply with local regulations. An ECV is recommended in all other geographical areas where the water supply has a tendency to cause scaling.
INSTALLATION INFORMATION SYSTEM ORIENTATION AND INCLINATION The performance of any solar hot water system is determined by the way that the system is installed. In Australia, the solar collectors should face the equator (North) as shown below. Where this orientation is not practical, collectors facing within 45 degrees from North (between North-East and North-West) area acceptable, with a reduction in efficiency of approximately 5%.
INSTALLATION INFORMATION For all installations the collector bank must slope upwards approximately 8 mm per collector from inlet to outlet as shown below: HOT CONNECTION BLANKED OFF CONNECTION BLANKED OFF CONNECTION COLD CONNECTION COLLECTOR BANK MUST SLOPE UPWARDS APPROX 8 mm PER COLLECTOR Figure 8 - Collector Banks ROOF MOUNTING OPTIONS For mounting options not shown in Figure 9, for example in areas where the cyclone frame can not be used, consult your nearest Rinnai Branch or Rinnai Representative

INSTALLATION & MAINTENANCE - GAS BOOSTED SYSTEMS GAS BOOSTER LOCATION The gas booster is designed for ‘Outdoor” Installation only. As such, it must be located in an above ground open air situation with natural ventilation, without stagnant areas, where gas leakage and products of combustion are rapidly dispersed by wind and natural convection. The location must comply with the clearances specified in AS 5601.
Rinnai Australia - 35 - Supply from solar storage cylinder Installations MUST conform to local regulataions. Refer to Rinnai manuals supplied with appliances for important installation information. Outlets to Personal Hygiene areas to be tempered to 50°C as per AS3500.
INSTALLATION MAINTENANCE - GAS BOOSTED SYSTEMS CLEARANCES Figure 5.3 is reproduced below. Note that AS 5601-2004 was current at time of printing but may have been superseded. It is the installer’s responsibility to ensure current requirements are met. AS 5601 - Figure 5.
INSTALLATION MAINTENANCE - GAS BOOSTED SYSTEMS INSTALLATION PROCEDURE 1. Install Solar Collectors and cylinders 2. • Position and install the solar collectors and cylinder in accordance with the section ‘INSTALLATION OF SOLAR COLLECTORS AND CYLINDERS”. Connect PTR Valve 3. • Connect the PTR Valve in the location shown in the relevant diagram of Figures 24 to 27. Leave the valve outlet pointing down. Tighten the valve using the spanner flats - never use the valve body.
INSTALLATION MAINTENANCE - GAS BOOSTED SYSTEMS FILLING THE SYSTEM CAUTION 1. 2. 3. Ensure building occupants are warned to stay clear of the solar system components, building perimeter and roof since hot water or steam may be discharged from pipes or components. Ensure the gas supply to the continuous flow water heater is isolated. Turn on one or more hot water taps at the sink. Open the stop cock in the cold water mains supply line. The entire system will now be filled with cold water.
INSTALLATION MAINTENANCE - GAS BOOSTED SYSTEMS 7. Check the hot water delivery temperature by placing a suitable thermometer at the hot water outlet closest to the gas booster. This is usually the hot water outlet in the kitchen. The delivery temperature should be greater than 55°C (this temperature allows for heat losses in pipe work). If the delivery temperature at the hot water outlet is lower than 55°C, check the delivery temperature at the outlet of the gas booster.
INSTALLATION & MAINTENANCE - ELECTRIC SYSTEMS INSTALLATION PROCEDURE 1. Install Solar Collectors and Cylinders Position and install the solar collectors and cylinder in accordance with the section “INSTALLATION OF SOLAR COLLECTORS AND CYLINDER”. 2. Connect PTR Valve • Connect the PTR Valve in the location shown in the relevant diagram of Figures 24 to 27. Leave the valve outlet pointing down. Tighten the valve using the spanner flats - never use the valve body.
INSTALLATION & MAINTENANCE - ELECTRIC SYSTEMS 7. ELECTRIC SUPPLY The power supply to the heating elements must not be activated until the system is filled with water. WARNING • The power supply can be either Off-Peak (overnight), Extended Off-Peak (overnight and day) or continuous, depending on the tariffs available from the local electricity supply authority. The OffPeak (overnight) power supply minimises the cost of any required electric boosting.
INSTALLATION & MAINTENANCE - ELECTRIC SYSTEMS PRE SOLAR HEATING CHECKS Before commencing solar heating of the water in the system ensure the following actions have been completed: Solar Collectors 1. Are the solar collectors installed with the correct slope and orientation to the sun? 2. Is the installation finished neatly with the roof made good, all tiles and flashings in place? 3. Are the bolts tight on the roof framework? 4.
