Introduction This manual is intended to be used by Rinnai accredited solar installers, who have a good understanding of the different types of solar systems and how they operate. The information contained is designed to reinforce information from the TradeSmart Solar Training Course, provide an understanding of the Rinnai Solar System, its suitability for use and high level instructions for installation. This manual should be used in conjunction with the following codes and standards: • AS/NZS 3500.
Solar collector fittings kits These are all the components for plumbing and mounting collectors on the roof.
Solar tank fittings kit SOLKITPUMPGE1 contains all the components for plumbing on and around the storage cylinder.
Cylinder location Inside or outside The Rinnai Glass Lined storage cylinders are suitable for mounting either inside or outside. Relevant regulations Cylinders should be installed to AS/NZS3500.4, with reference to G12/AS1 where appropriate. Base requirements Cylinders should be installed on a flat level base of sufficient strength to support the weight of the water heater when full. It must also be suitably restrained against seismic activity.

Mounting the solar controller and pump 1. Mount the solar controller in a suitable position on the side of the cylinder or adjacent wall using suitable fasteners. 2. Change position of the riser tube to solar enable the Hotflo storage cylinder using the dip tube provided in the tank fittings kit. - Select which upper hot outlet will be used for the hot solar return - Invert the riser tube using the wire tool supplied 3.
Mounting the solar controller and pump 4. Run a piece of insulated 12 mm od copper tube from the cold inlet to the pump. Ensure the pump is installed correctly with the impeller in a vertical not horizontal position. 5. Uncoil the cold temperature sensor in the control box and feed it out of the gland in the bottom of the control box. Do not attach it to the pipe work until the commissioning stage. 6. Set pump controller for panel type. This controls the hot water circulation for frost protection.
Mounting collectors on the roof - general Roof sizing and collector weight Each Rinnai solar collector is approximately 2 m tall by 1 m wide. Select a location with sufficient space for the collectors and associated plumbing connections. The collectors weigh approximately 40 kg each and due care and skill should be taken when lifting them onto the roof.
Mounting collectors on the roof - general Pipe connections between collector and tank Hot collectors WARNING ▪ Connecting pipes should pitch up continuously from the tank to the collector to prevent air-locking ▪ Insulation should be of a suitable material to withstand high temperatures in solar systems and be protected with UV resistant tape or other coating ▪ Maximum total flow and return pipe length between cylinder and collector is 50 m The surface and frames can become extremely hot.
Mounting collectors on a metal roof The Rinnai standard mounting rails are for arrangements where the hot outlet connection is on the top right hand corner. If you have an arrangement that requires a top left hot outlet connection you will need a different top mounting rail. This can be purchased as an accessory from Rinnai. Unpainted galvanised roofs will require painting under the area where the collector is installed and any subsequent run off areas (e.g. down the guttering below). 1.
Mounting collectors on a metal roof 5. Fit lower mounting rail to the straps Fasten the lower mounting rail through the straps to the roof and in additional places as required. Check the distance between the inside faces of the mounting rails is correct. 6. Fit additional Fit additional straps so there are two straps per collector. Each fastener straps as should be sealed with suitable washers, both under the head of the required fastener and between the rail and roof, as shown below.
Mounting collectors on a metal roof 7. Fit collectors To assist in fitting the collectors there are a series of M5 threaded holes along the mounting rails. In the solar collector fittings kit are M5 fasteners. These should be inserted into the holes in the rail before the collectors are fitted. These will act as ‘stoppers’. Fit the collectors into the mounting rails. The stoppers will position the panels at the right height for the slots to align so the mounting fasteners can insert easily.
Mounting collectors on a tile roof The Rinnai standard mounting rails are for arrangements where the hot outlet connection is on the top right hand corner. If you have an arrangement that requires a top left hot outlet connection you will need a different top mounting rail. This can be purchased as an accessory from Rinnai. G12 requires stainless steel straps for tile roofs. The Split System Solar Fittings Kits have galvanised straps as standard.
Fitting connecting pipes and sensor lead All penetrations through the roof for connecting pipes and hot sensor lead should be made using suitable sealing boots such as dektites. 1. Attach plumbing fittings Run piping and insulate Attach necessary plumbing fittings to the collector(s) as shown below. Compression fittings are designed for 12 mm outside dimension (od) copper tube. Run and insulate piping between the pump outlet and bottom left corner of the collector(s).
Supplementary boosting - gas Install a Rinnai continuous flow water heater using a flow diversion valve as shown below. The water heater must be set to 75 oC. All Rinnai Infinity units installed in a solar system require a flow diversion valve and a dipswitch change to the required 75 oC. (Remember ‘B to Boiler’ when setting up the flow diversion valve).
Supplementary boosting - electric All Rinnai storage cylinders come pre-equipped with electric elements and thermostats. Electrical connections The cylinders are pre-wired. A 20 mm mounting hole for conduit termination is provided under the element cover. A 2 way terminal block is provided for connection of Active and Neutral wires (pictured) and a brass terminal block is provided for connection of the earth cable.
Commissioning the solar system Until system filling and commissioning is complete: WARNING • Keep solar panels covered • Do not plug in the solar controller / pump or connect a power supply to boost the element until step 6 1. If a gas boost is fitted, open the inlet and outlet water valves at the Rinnai Infinity but do not connect the power supply at this point. 2. Open a hot tap at the sink. 3. Open the cold water inlet to the storage cylinder. 4.
Consenting requirements for solar The following information is from the EECA Solar Water Heating Guidebook, Version 1, October 2006, Section 2. The installation of a solar hot water heating system requires a Building Consent because solar water heating systems interact with potable water supplies and can involve heavy loads on roof structures if the hot water cylinder is mounted on the roof. A Building Consent is also required where there is a change to a potable water supply system and to the heat source.
