WARNINGS AND IMPORTANT INFORMATION

OPERATION PRINCIPLE

Close coupled systems are designed to have the solar collectors on the roof and the storage cylinder above the collectors, all mounted using available mounting brackets� Electric and gas boosted models are available� The system comprises of a hot water storage cylinder and solar collectors� Close coupled solar systems use the thermosyphon principle to circulate the water through the collectors and then to the storage cylinder without the need for a pump�

Supplementary heating is provided if insufcient heat is available from sun (such as during cloudy or rainy weather

or during winter months) either via an electric heating element located inside the storage cylinder or via a gas booster located external to the storage cylinder� The following diagrams illustrates the systems set up for electric and gas boosting�

WARNING

WARNINGS AND IMPORTANT INFORMATION

SAFETY DEVICES

The water heating system is supplied with various safety devices including temperature sensors, overheat sensors and switches and a Pressure & Temperature Relief (PTR) valve� These devices must not be tampered with or

removed. The water heating system must not be operated unless each of these devices is tted and is in working

order�

DO NOT tamper with or remove safety devices.

DONOToperatethewaterheaterunlessallsafetydevicesarettedandinworkingorder.

DO NOT block or seal the PTR Valve and drain pipe.

Pressure & Temperature Relief (PTR) Valve

This valve is located near the top of the water heater and is essential for safe operation� It is normal for the valve to release a small quantity of water through the drain line during heating�

However, continuous leakage of water from the valve and its drain line may indicate a problem with the water heater�

Twist cap until w ater flows from drain line

Lift lever until w ater flows from drain line (Lower lever gently!)

Never block the outlet of the PTR valve or it’s drain line for any reason. The easing gear must be operated at least every 6 months to remove lime deposits and verify that it is not blocked. Failure to do this may result in the water heater failing.

If the valve does not discharge water when the easing gear lever is opened, or does not seal again when the easing gear is closed, attendance by an authorised person must be arranged without delay. The PTR valve is not serviceable.

EXCESSIVE DISCHARGE FROM SAFETY DEVICES Pressure & Temperature Relief (PTR) Valve

It is normal and desirable that this valve allows a small quantity of water to be discharged during the heating cycle� If it discharges more than a bucket of water during a 24 hour period or discharges continuously there may be another problem�

If the valve dribbles continuously, try easing the valve gear for a few seconds as described above� This may dislodge any foreign matter and alleviate the problem�

If the valve discharges at high ows, especially at night, it may be as a result of the water pressure exceeding the design pressure of the water heater. Ask your installer to t a Pressure Limiting Valve (PLV).

NEVERreplacethePTRvalvewithonewhichhasahigherpressureratingthanisspeciedfor

your water heater.

Expansion Control Valve (ECV) - if tted

It is normal and desirable that this valve allows a small quantity of water to be discharged during the heating cycle� If it discharges more than a bucket of water during a 24 hour period or discharges continuously there may be another problem�

If the valve leaks continuously, try easing the valve gear for a few seconds� This may dislodge any foreign matter and alleviate the problem� If this does not alleviate the problem contact Rinnai�

Operate the easing gear regularly to remove any lime deposits and to verify that it is not blocked�

WARNINGS AND IMPORTANT INFORMATION

GAS BOOSTERS

Do not touch the ue outlet or do not insert any objects into the ue outlet.

•

Keep ammable materials, spray cans, fuel containers, trees, shrubs and pool chemicals etc, well clear of

•

the ue outlet.

Do not use the gas types other than those designated on the data plate� For example, do not use Propane/

•

Butane gas mixtures on appliances marked Propane Gas� Do not use Propane Gas on appliances marked as Natural Gas and vice versa�

•

HYDROGEN GAS

In the case of systems using a vitreous enamel lined cylinder, if the hot water unit is not used for two weeks or

more, a quantity of hydrogen gas, which is highly ammable, may accumulate in the water heater. To dissipate this

safely, it is recommended that a non electrically operated hot tap be turned on for two minutes at a sink, basin, or

bath, but not a dishwasher or other appliance. During this procedure there must be no smoking, open ame or any

electrical appliance operating nearby � If hydrogen is discharged through the tap, it will probably make a sound like air escaping�

WATER TEMPERATURE

The water gets heated by the solar energy contributed from the sun and heats the water until the water at the base of the storage cylinder reaches approximately 65°C� At this time water at the hot outlet can be up to 88°C� Continued heating is prevented by the ‘No Load’ protection, a Thermo-arrestor (TA) valve that prevents water passing from the cylinder to the collectors� During periods of low solar gain, supplementary heating occurs�

To meet Australian regulatory requirements, supplementary heating must be operational.

TURNING OFF THE WATER HEATING SYSTEM

If you plan to be away for only a few nights, we suggest you leave the water heating system switched on� If it is necessary to switch off the water heater, do so as outlined below:

Electric Boosted Systems

Switch off the electrical supply to the supplementary heating element� The switch is usually marked and

•

located in the electricity meter box of the dwelling�

Gas Boosted systems

Switch off the electric supply to the gas booster�

•

TURNING ON THE WATER HEATING SYSTEM

Electric Boosted Systems:

Often people are surprised at the amount of hot water used, especially when showering� If the amount of hot water used during the day exceeds the storage capacity

of the cylinder, it is likely that there will be insufcient hot water.

Gas Boosted Systems:

Insufcient ow may occur if multiple outlets are in use at the same time and exceed the rated ow capacity of the gas booster. If so, reduce the number of outlets in use.

or pressure limiting valves to reduce consumption�

PTRValves&ECVValves(iftted)

It is normal and desirable that these valves allows a small quantity of water to be discharged during the heating cycle� If they discharges more than a standard bucket of water during a 24 hour period or discharges continuously there may be another problem

If water continuously dribbles from the valve, try easing the valve gear for a few seconds as described in This may dislodge any foreign matter and alleviate the problem�

If the valve discharges at high ows, contact your installer or Rinnai to discuss.

Electric boosted Systems:

Check to ensure the electric isolating switch(es) at the switchboard (usually marked “Hot water” or “water heater”) is switched ‘ON’�

Check to ensure that the electric fuses for hot water at the switchboard are intact If running on Off-Peak, discuss boosting times with electricity supplier�

Booster heating not operating or insufcient gas supply for gas boosted heating system

Gas Boosted Systems:

Check to ensure the power cord of the gas booster is plugged in and switched ‘on’� Check gas is available and the isolation valve is opened Close the hot tap and wait for 10 seconds and open it again� The hot tap must be

opened enough to ensure that the ow rate is sufcient for the gas booster to light.

Check if there is gas supply to other appliances in the rest of the house

Check the temperature of hot water delivered with a thermometer placed under the closest outlet (usually the kitchen sink) on a non-tempered hot water line

This test should be done early in the morning after overnight electrical boosting before any hot water is used� The temperature of the water delivered should be at least 55°C (allowing for heat losses in pipe work)

If this is not the case or the temperature may need to be increased� Contact your

installer or Rinnai to discuss adjusting the thermostat.

Check for water ow at the other hot taps and that the cold water isolation valve is fully

open

SAVE A SERVICE CALL

HIGH ELECTRICITY OR GAS BILL Hot water usage patterns Electric Boosted Systems:

If using an off peak (overnight) boosted electrical system, the time of use of the water may affect whether heating is done by electric element or solar energy� This is because both solar heated water and electrically heated water are stored in the same cylinder� As the element is in the middle of the tank, half the tank can be heated each night by the booster element�

If the bulk of hot water is used in the morning, there will be cold water in the cylinder for the sun to heat during the day leading to lower electricity usage�

If the bulk of the hot water is used in the evening, the electric element will reheat the water overnight� In the morning there will only be half a cylinder of cold water for the sun to heat�

Consider changing your usage pattern to optimise solar energy usage�

High electricity cost Electric Boosted Systems:

The electricity tariff will determine the running costs of the system� Contact the

electricity supplier to conrm what these tariffs are.

If the solar collectors are shaded by trees or other objects, or the glass is dirty, the

effectiveness of the collectors is greatly reduced� Arrange for trimming of the trees or relocation of the solar collectors if the obstruction is permanent� Arrange for cleaning of the collector glass

Solar collectors incorrectly positioned will also severely affect the solar gain� Check that positioning and alignment of solar collectors is in accordance with the section ‘System Orientation and Inclination’ on page 20�

There is a small amount of ventilation between atmosphere and the internals of the

solar collector to ensure efcient operation. Under certain weather conditions, water

vapour naturally present in the air may condense on the inside surface of the collector glass� This does not affect the performance of the system� If you are concerned contact Rinnai to discuss�

REGULATIONS AND OCCUPATION HEALTH AND SAFETY (OH&S)

Installation and commissioning must be performed by authorised persons� 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� Applicable publications and regulations may include:

AS/NZS 5601 Gas Installations

•

AS/NZS 3500 National Plumbing and Drainage

•

AS/NZS 3000 Wiring rules

•

Building Codes of Australia (BCA)

•

Local Occupational Health and Safety (OH&S) regulations

•

This appliance is not suitable for use as a domestic spa pool or swimming pool heater� Solar collectors and cylinders are heavy and bulky items and are usually positioned on the roofs of

buildings� Australian State and Territories have a principal Occupational Health and Safety (OH&S) Act which contains requirements relating to the handling of large, bulky or awkward items and the prevention of falls from elevated surfaces� Persons installing solar collectors must be aware of their

responsibilities and be adequately trained and qualied, in accordance with local OH&S requirements.

LOCATION

System Location

These systems are only suitable for use on buildings up to 10 metres tall�

Select suitable areas of roof on which to install the solar collectors and cylinder� It is essential that the roof structure is suitable for the solar collector/cylinder combination and can support the weight of these items when full of water� It is the installers responsibility to ensure the roof can safely support the system and to visually check the roof, and if there is any damage that requires attention (such as cracked tiles etc�), to inform the owner� If this affects

the safe installation of any part of the system, installation should not proceed until the damage has been rectied.

Collectors should be positioned for optimum solar benet. Refer to the section ‘System Orientation and Inclination’

on page 20 for more information�

All system components must be in an accessible location. Sufcient clearances shall allow access to, and removal of, all serviceable parts. Ensure the PTR valve, drain lines, thermostats and elements have sufcient clearances

and are accessible for service and removal� The information on any data plates must also be readable� All electrically boosted solar hot water heating elements must be connected to an independent, fused, AC 240V 50

Hz power supply with an isolating switch installed at the switch board�

Gas Booster Location (where applicable)

The S20, S26 and S32 gas boosters are designed for outdoor installation only � As such, they must be located in an above ground open air situation with natural ventilation, without stagnant areas, where gas leakage & products of combustion are rapidly dispersed by wind and natural convection� If an internal model which has been converted

IMPORTANT

INSTALLATION - ALL SYSTEMS

WATER PIPES, FITTINGS AND INSULATION

The solar hot and solar cold pipes between the solar storage tank and solar collector(s) must be

copper tube. Fittings used to join these pipes must use metallic materials to achieve sealing. Plastic pipe and ttings must not be used as they are not suitable for the high temperatures and pressures that may occur. Failure of plastic pipe and/or ttings can lead to the release of high temperature water and can cause severe ooding and water damage.

All hot water pipework should be insulated with sealed polyethylene foamed or equivalent insulation to optimise

performance and energy efciency, and to protect against frost damage. Such insulation may also be mandatory

under local regulations� Rinnai recommend insulation to achieve at least the R value shown in the following table�

• CER Zone 4

• Areas dened as “B or “C” in the latest version of the Rinnai Solar Hot Water Warranty Booklet�

R = 0�6 K�m²/W R = 0�6 K�m²/W

• Any other area prone to frost conditions�

• All other areas R = 0�6 K�m²/W insulation not required

With the exception of solar collector ow and return pipes, water pipe sizing should be performed in accordance

with AS/NZS 3500�

All supplied insulation materials must be tted as shown to minimise heat losses. In frost prone areas this insulation will also protect against frost damage. If frost valves are tted they must remain free of any insulation materials.

Frost valves must be exposed directly to ambient air conditions to ensure correct operation�

WATER SUPPLY

The maximum water pressures for the various systems are listed on page 12� Approved pressure limiting valves may be required if the ‘Maximum’ rated water supply pressures are exceeded� For gas boosted systems to achieve

the rated ow through the outlet of the continuous ow water heater, the minimum water supply pressures must be supplied. The systems will operate at lower pressures but the rated ow will not be achieved.

Water chemistry and impurity limits are detailed in the separate warranty booklet� Most metropolitan water supplies fall within these requirements� If you are unsure about water quality, contact your water authority� If sludge or

foreign matter is present in the water supply, a suitable lter should be incorporated in the water supply to the

storage cylinder�

Local regulations and/or the requirements of AS/NZS 3500�4 must be considered regarding the temperature limitations of hot water supplied to areas used primarily for personal hygiene� The temperature of water to these areas is limited to 45°C for early childhood centres, primary and secondary schools and nursing homes or similar facilities for young, aged, sick or people with disabilities and 50°C for all other buildings� To comply with these requirements, a temperature limiting device, such as a thermostatic mixing or tempering valve, will be required on all solar hot water systems as detailed below�

VALVES AND FITTINGS

The following valves and ttings are supplied with your solar hot water system:

A combined pressure and temperature (PTR) relief valve, capacity 10 kW� Relief valve pressure settings

•

vary with models. This valve is tted at the top of the storage cylinder. The PTR valve is a safety device and it is mandatory that it is tted by the installer in all installations.

Thermo-Arrestor (TA) valve. This valve is tted on the inlet pipe to the solar collectors. Its function is to

•

control the ow of water from the tank to the collectors and stop the ow of water when the tank has reached

the required temperature�

For gas boosted systems, elbow connections for the hot, cold and gas supply are tted at the bottom of the

•

gas booster� Fittings as shown on pages 32 to 47

•

The following valves & ttings are to be supplied by the installer:

BATHROOM

ENSUITE

A cold water expansion control valve (ECV). An ECV must be tted 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� This will reduce hot water discharge from the pressure and temperature relief (PTR) valve which minimises wear on this valve�

A stop cock, non return valve and line strainer� Combination valves incorporating two or more of these

•

functions (such as ‘Trio’ valves) are suitable. These are tted to the cold water supply to the storage cylinder

by the installer� Cold water supply and hot water discharge pipework to and from the storage cylinder�

•

An isolating valve and connection union for the gas supply to the gas booster�

•

An approved pressure limiting valve (supplied with some systems) is required if the maximum rated water

•

supply pressure on page 12 is exceeded�

INSTALLATION - ALL SYSTEMS

SYSTEM ORIENTATION AND INCLINATION

The performance of any solar hot water system is determined by the way the system is installed� For Australian installations, solar collectors should face the equator (True North) for optimum performance�

Installing solar collectors facing up to 45 degrees away from North (between North-East and North-West) will

reduce efciency by approximately 5%.

For Australian installations, the inclination of solar collectors should be the same as the latitude of the site for

optimum performance. Inclinations within 20 degrees of the latitude of the site will reduce efciency by approximately 5%. Most roofs in Australia have a slope of between 20° and 25° and provide an appropriately angled mounting

surface�

Installers must ensure they comply with relevant local regulations regarding solar collector inclination and orientation.

ROOF MOUNTING OPTIONS

These systems are not suitable for use on roofs over 10 m high�

For roofs with a slope of 10° or less a at roof frame must be used.

Rinnai do not recommend installing Close Coupled systems on roofs with a pitch greater than 30°� An additional strap should be used to prevent the cylinder from tipping over if a system is installed in this manner� Refer page 28�

It is normal to mount the solar collectors down close to the gutter� Roof construction must be checked to ensure that the roof timbers are capable of supporting the additional load� (Refer to AS 3500�4 Appendix H)�

For tiled roof installations� Check for cracked or damaged tiles in the area of proposed installation� Replace any faulty tiles� If spare tiles are not available, swap damaged tiles with good ones from along the gutter line�

NOTE

INSTALLATION - GAS BOOSTED SYSTEMS

GAS BOOSTER LOCATION

The S20, S26 and S32 gas boosters are designed for outdoor installation only � As such, they 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

specied in AS/NZS 5601.

The gas booster must be mounted on a vertical structure with the water and gas connections on the underside pointing downwards� The heated outlet of the cylinder is connected to cold water inlet of the gas booster�

Ensure that the wall or structure on which it is to be mounted are capable of supporting the weight of the appliance and associated pipe work� See page 16 for individual gas booster weights� For gas boosters installed on elevated

structures or under oors specic requirements apply.

Refer to AS/NZS 5601 for details�

Attach the gas booster to the wall using screws�

•

Location of the gas booster ue terminal must be in accordance with Figure 6.2 of AS/NZS 5601.

•

If an internal model which has been converted to a solar gas booster follow information supplied with the unit for

location, mounting and ueing requirements.

GAS SUPPLY

The maximum gas consumption of the gas booster and the required gas pressure are shown on the appliance data

plate. If the gas pipe sizing is insufcient the customer will not get the full performance benet.

Gas pipe sizing must consider the gas input to the gas booster as well as all the other gas appliances on the

premises. The gas meter and regulator must be specied for this gas rate. An approved sizing chart such as the

one in AS/NZS 5601 should be used�

An approved full ow isolation valve and disconnection union must be tted to the gas supply inlet of the gas booster. Isolation valves must not be tted directly to the booster.

HOT WATER DELIVERY TEMPERATURE

Gas boosters for use in solar hot water systems are preset to deliver a xed temperature of 70°C in accordance with

plumbing regulations� In addition, they contain the warning stating “Rinnai Water Controllers are NOT compatible with solar hot water installations and MUST NOT BE USED in the vicinity of the temperature controller connections inside the appliance�”

Gas Boosters other than models designated “S20”, “S26”, “S26i”, “S32” or “Solar” must not be used� Gas Boosters marked with the text: “THIS APPLIANCE DELIVERS WATER NOT EXCEEDING 50°C IN ACCORDANCE WITH AS 3498” are incompatible with solar hot water systems and must not be used�

SMARTSTART®

The Smartstart® is a separate system that works in conjunction with the Rinnai solar hot water system.

When activated by the manual activation switch, water in the pipework connected between the solar hot water system and the hot water outlets is warmed before any outlets are opened� This results in water savings and added convenience� Refer to page 49 for installation details�

NOTE

WARNING

INSTALLATION - GAS BOOSTED SYSTEMS

INSTALLATION PROCEDURE

1. Install Solar Collectors and cylinders

Position and install the solar collectors and cylinder in accordance with the section ‘Standard Installation’ on page 24� or the section ’Framed Installations’ on page 29�

2. Connect PTR Valve

Connect the PTR Valve in the location shown in the relevant diagram on pages 32 to 47� Leave the valve

outlet pointing down. Tighten the valve using the spanner ats - never use the valve body.

The PTR Valve must be adequate for the thermal loading applied to the storage cylinder� In the case of gas

boosted systems, the thermal load is applied only by the solar collectors. The continuous ow hot water

heater does not apply thermal load to the storage cylinder� The potential solar output for the solar collectors at PTR Valve relief conditions is listed on page 15�

The PTR Valve pressure ratings vary according the cylinder specications. The maximum heater input rating

is 10�0 kW� The PTR valve rating MUST EXCEED the total input from the solar collectors� If it does not, the PTR valve MUST be exchanged for a model of higher capacity�

For example, for a gas boosted solar system with 3 x SP200B collectors, the thermal load is 3 x 1�25 = 3�75

kW. This is less than 10.0 kW, hence the supplied PTR valve is of sufcient capacity.

Use Teon thread tape on the valve, never use hemp or other sealing materials. Ensure the tape does not

protrude past the end of the thread, which could result in it hanging over the end of the thread and blocking the water passage through the valve�

3. Mount Gas Booster

Mount the gas booster in accordance with the section ‘Gas Booster Location’ on page 48�

4. Connect Water to Gas Booster

Connect the outlet of the storage cylinder to the water inlet of the gas booster�

5. Connect Fittings

Connect ttings and pipe work as shown in the relevant diagram on pages 32 to 47�

6. Cold Water Supply

Connect cold water supply to the T/A valve inlet. Ensure that the relevant valves are tted as described inthe section ‘Valves and Fittings’ on page 19�

Purge the cold water supply lines to remove air and swarf before nal connection.

7. Relief Drain Lines

Independent 15 mm copper pipes must be tted to the drain outlets of the PTR and ECV. Each pipe must

be open to atmosphere and run with a continual downward grade in a frost free environment to a visible discharge point� Drain lines must not exceed 9 metres in length�

Valves or other restrictions must not be placed in the relief valve drain outlet line�

Some water will drip from the drain lines during heating of the water in the storage cylinder� It is recommended to discharge directly above a drain�

8. Hot Water Discharge

Connect the hot water outlet of the gas booster to the pipe work supplying hot water to the premises�

A temperature limiting device may be required as detailed in the section ‘Hot Water Delivery Temperature’ on page 19�

Rinnai 51 CC B OIM

CAUTION

INSTALLATION - GAS BOOSTED SYSTEMS

9. Connect Gas to Booster

Connect a suitable gas supply and isolating valve to the gas booster� Follow instructions supplied with gas booster� Keep gas booster isolated at this stage�

FILLING THE SYSTEM

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�

1� Ensure the gas supply to the continuous ow water heater is isolated. 2� Turn ‘ON’ the hot water tap at the sink� Open the stop cock in the cold water mains supply line� 3� The entire system will now be lled with cold water. Most air will be dispelled through the tap. Some air needs

to be bled from the air bleed valve on the collectors�

4� Turn ‘OFF’ the hot tap at the sink when water ows freely without air bubbles or air bursts. Check all connections

for leakage and tighten if necessary. This applies especially to ttings in positions not easily accessed such

as near the solar collectors� Operate the easing gear of both the PTR and ECV valves at the storage cylinder to ensure these valves are functional�

If leaks are detected the system must be drained and leaks repaired before the system is relled. If

this is necessary, cover the solar collectors with packaging cardboard or a tarp to prevent them from

heating which could result in steam or hot water being discharged from ttings..

PRE SOLAR HEATING CHECKS

Before commencing solar heating of the water in the system ensure the following actions have been completed:

Solar Collectors and Cylinder

1� Are the solar collectors installed with the correct slope and orientation to the sun? 2� Is the installation nished neatly with the roof made good, all tiles and ashings in place? 3� Are the bolts tight on the roof framework? 4� Are all solar collector and cylinder straps tted and correctly anchored to the roof structure? 5� If leak testing completed and successful, have any covers been removed from the solar collectors?

Gas Booster

1� Ensure the gas supply is isolated� Remove the test point screw located on the gas inlet connection and attach

a pressure gauge� 2� Turn on the electrical power to the gas booster and turn on the gas supply� 3� Ensure the cold water inlet (‘trio’) valve on the storage cylinder inlet is open� Open all available hot water taps� 4� Operate ALL other gas appliances at their maximum gas rate, in accordance with manufacturers instructions�

Ensure building occupants do not have access to hot water outlets during this procedure�

5� With all gas appliances in operation at the maximum gas rate, the pressure should read between 1�13 - 3�0

kPa on Natural Gas� On LPG the pressure should be 2�75 - 3�0 kPa� If the pressure is lower, the gas supply

is inadequate and the appliance will not operate to specication.

It is the installers responsibility to check the gas meter, service regulator and pipe work for correct operation/

sizing & rectify as required� Note that the gas regulator on the appliance is electronically controlled and factory

pre-set. Under normal circumstances it DOES NOT need adjustment during installation. Make adjustments

only if the gas booster is not operating correctly and all other possible causes for incorrect operation have

been eliminated� Instructions for gas pressure setting are located in the pocket behind the front cover of the

gas booster�

INSTALLATION - GAS BOOSTED SYSTEMS

6� Close the hot water taps including the shower� 7� Close the cold water inlet (‘trio’) valve on the storage cylinder inlet and inspect and clean the strainer� Repeat

for the strainer connected at the inlet of the gas booster� This procedure may need to be repeated to ensure

the strainers remains clear, especially on new installations� 8� Conrm the hot water delivery temperature from the gas booster. This is done by checking the hot water

delivery temperature at an untempered outlet close to the water heater� This is usually the hot water outlet in

the kitchen� The untempered hot water delivery should be between 65°C & 70°C�

Temperature Limiting Devices

1� Commission any temperature limiting devices in accordance with the instructions supplied by the manufacturer� 2� Conrm the hot water delivery temperature at a tempered water outlet. Tempered water outlets should be

those supplying areas primarily used for the purposes of personal hygiene such as bathrooms� The hot

water delivery temperature should not exceed 50°C or 45°C as detailed in the section ‘Hot Water Delivery

Temperature’ on page 19�

SOLAR HEATING

1� Remove any cardboard or tarp covers that may have been placed over the solar collectors to prevent them

from heating water during installation and commissioning� Solar heating of the water in the cylinder will now

commence when sufcient solar radiation is available.

2� Activate electrical power to both the gas booster�

FINISHING THE INSTALLATION

1� After testing is completed explain to the householder the functions and operation of solar water heater

components and the importance of carrying out Maintenance as per separate warranty document� 2� Complete the installation record at the back of the manual� 3� Leave this manual and the warranty booklet with the householder�

DRAINING INSTRUCTIONS

1� The power supply to the gas booster must be switched off� 2� Close the cold water mains supply stop cock� 3� Open a hot tap to relieve pressure� 4� Disconnect the cold water connection to the Thermo-arrest (T/A) valve� 5� Remove the brass plug on the bottom right hand side of the collector bank� 6� Disconnect the ‘water inlet’ and ‘water outlet’ connections at the gas booster� 7� The system will now drain all water�

INSTALLATION PROCEDURE

1. Install Solar Collectors and Cylinders

Position and install the solar collectors and cylinder in accordance with the section ‘Standard Installation’ on

page 24� or the section ’Framed Installations’ on page 29�

2. Connect PTR Valve

Connect the PTR Valve in the location shown in the relevant diagram of pages 32 to 47� Leave the valve

outlet pointing down. Tighten the valve using the spanner ats - never use the valve body.

The PTR Valve must be adequate for the thermal loading applied to the storage cylinder� In the case of gas

boosted systems, the thermal load is applied only by the solar collectors. The continuous ow hot water

heater does not apply thermal load to the storage cylinder� The potential solar output for the solar collectors

at PTR Valve relief conditions is listed in page 15�

The PTR Valve pressure ratings vary according the cylinder specications. The maximum heater input rating

is 10�0 kW� The PTR valve rating MUST EXCEED the total input from the solar collectors� If it does not, the

PTR valve MUST be exchanged for a model of higher capacity�

For example, for a gas boosted solar system with 3 x SP200B collectors, the thermal load is 3 x 1�25 = 3�75

kW. This is less than 10.0 kW, hence the supplied PTR valve is of sufcient capacity.

Use Teon thread tape on the valve, never use hemp or other sealing materials. Ensure the tape does not

protrude past the end of the thread, which could result in it hanging over the end of the thread and blocking

the water passage through the valve�

3. Connect Fittings

Connect ttings and pipe work as shown in the relevant diagram on pages 32 to 47�

4. Cold Water Supply

Connect cold water supply to the T/A valve inlet. Ensure that the relevant valves are tted as described in the

section ‘Valves and Fittings’ on page 19�

Purge the cold water supply lines to remove air and swarf before nal connection.

5. Relief Drain Lines

Independent 15 mm copper pipes must be tted to the drain outlets of the PTR and ECV. Each pipe must

be open to atmosphere and run with a continual downward grade in a frost free environment to a visible

discharge point� Drain lines must not exceed 9 metres in length�

Valves or other restrictions must not be placed in the relief valve drain outlet line�

Some water will drip from the drain lines during heating of the water in the storage cylinder� It is recommended to discharge directly above a drain�

6. Hot Water Discharge

Connect the hot water outlet of the gas booster to the pipe work supplying hot water to the premises�

A temperature limiting device may be required as detailed in the section ‘Hot Water Delivery Temperature’ on page 19�

WARNING

CAUTION

INSTALLATION - ELECTRIC BOOSTED SYSTEMS

7. Electric Supply

The power supply to the heating elements must not be activated until the system is lled with water.

Wiring of Electric Element

The power supply to the element of the solar storage cylinder can be off-peak (overnight), extended off-peak (overnight and day), continuous or other tariffs available from the local electricity supply authority� Rinnai strongly recommends the use of an off-peak tariff to ensure that solar heating takes priority over electrical heating� If this tariff isn’t available, then a timer can be used to limit electrical heating to non solar hours�

A exible 20 mm conduit is required for the electrical cable to the

storage cylinder� The conduit is to be connected to the unit with a 20 mm terminator� Connect the power supply wires directly to the terminal block and earth tab connections ensuring there are no excess wire loops inside the front cover�

Heating Element Thermostat Temperature Settings

Australian Standards require a minimum thermostat set point of 60°C to inhibit the growth of Legionella Pneumophilia bacteria� In the interests of durability, the thermostat set point for storage cylinders should not exceed 70°C� Hence, the thermostat set point should be at least 60°C and no greater than 70°C�

FILLING THE SYSTEM

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�

1� Ensure the electric power supply to the water heater is switched ‘OFF’� 2� Turn ‘ON’ the hot water tap at the sink� Open the stop cock in the cold water mains supply line� 3� The entire system will now be lled with cold water. Most air will be dispelled through the tap. Some air will

need to be bled from the air bleed valve on the collectors� 4� Turn ‘OFF’ the hot tap at the sink when water ows freely without air bubbles or air bursts. Check all connections

for leakage and tighten if necessary. This applies especially to ttings in positions not easily accessed such

as near the solar collectors� Operate the easing gear of both the PTR and ECV valves at the storage cylinder

to ensure these valves are functional�

If leaks are detected the system must be drained and leaks repaired before the system is relled. If

this is necessary, cover the solar collectors with packaging cardboard or a tarp to prevent them from

heating which could result in steam or hot water being discharged from ttings..
