Page 8: Installation
The solar storage cylinders have an ingress protection rating of IPX4 making them suitable for internal or external installation. Rinnai ‘external’ gas boosters are suitable for external installation only. Storage cylinders must be installed in freestanding mode on a level and stable base. For external installations, storage cylinders should be mounted on a concrete base at least 50mm thick or on well seasoned, evenly spread hardwood slats with a thickness of at least 25mm. -
Page 9: Water Pipes
WATER PIPES All hot water pipework should be insulated with sealed Polyethylene foamed or equivalent insulation to optimise performance and energy efficiency. Such insulation may also be mandatory under local regulations. Rinnai recommend insulation to achieve an R value of 1.0 K.m2/W. With the exception of solar collector flow and return pipes, water pipe sizing should be performed in accordance with AS/NZS 3500. All external pipework MUST be insulated to prevent frost damage. -
