Insulation Of Pipes; Temperature Protection; Inlet Connections - Rinnai GHF4135N Operation & Installation Manual

GENERAL INSTALLATION INSTRUCTIONS

Insulation of Pipes

All hot water pipes must be insulated with UV stabilised insulation.

Temperature Protection

Water heaters can produce very hot water. To reduce the risk of scald injury, it is mandatory under
the requirements of Australian Standard AS/NZS 3500.4 that a suitably approved temperature control
device be fitted to the hot water supply to outlets used primarily for personal hygiene. This valve
should be checked at regular intervals to ensure its operation and settings remain correct.
