INSTALLATION
Rheemglas 850 Series – Hot Water Outlet
A Rheemglas 850 series water heater can deliver hot water at a temperature up
to 65°C depending upon the thermostat setting, sufficiently hot to cause severe
scalding. Water at this temperature may be plumbed to fixtures where water
hotter than 50°C is allowed, such as the kitchen and laundry.
The installing plumber may have a legal obligation to ensure the installation of
this water heater meets the water temperature delivery requirements of the
Plumbing Code of Australia so that heated water delivered to fixtures and
appliances used primarily for personal hygiene is at a temperature which is
unlikely to scald.
It is necessary and we recommend that a temperature limiting device be fitted
between a Rheemglas 850 series water heater and the fixtures and appliances
used primarily for personal hygiene such as in a bathroom, ensuite, public
amenities or other ablution areas, to reduce the risk of scalding.
Where a temperature limiting device is installed adjacent to the water heater, the
cold water line to the temperature limiting device can be branched off the cold
water line either before or after the isolation valve, pressure limiting valve and
non-return valve to the water heater. If an expansion control valve is required, it
must always be installed after the non-return valve and be the last valve prior to
the water heater.
If a pressure limiting valve is installed on the cold water line to the water heater
and the cold water line to a temperature limiting device branches off before this
valve or from another cold water line in the premises, then a pressure limiting
valve of an equal pressure setting may be required prior to the temperature
limiting device.
