Rheem 871 Series Owner's Manual And Installation Instructions page 71

PRESET OUTLET TEMPERATURE SETTING
The factory preset outlet temperature setting of the water heater is:
• 871 series (pre 2007 manufacture date)
• 871 series (from 2007 manufacture date)
• 875 series
If a temperature controller is connected to the water heater, this will override the preset outlet temperature
setting and the maximum temperature setting will be:
Maximum Outlet Temperature
Kitchen controller connected
Bathroom controller only connected
It is usually not necessary to check or adjust the factory preset outlet temperature setting of the water heater,
unless the customer has a particular requirement for this to be done or it is to be installed as an in-series gas
booster to a solar water heater.
Gas Booster for a Solar Water Heater
Note: Australian Standard AS 3498 requires that a water heater provides the means to inhibit the growth of
Legionella bacteria in potable water. When this water heater is used as an in-series booster for a solar water
heater it can satisfy this AS 3498 requirement provided it is energised, the booster preset outlet temperature
setting is 70°C, and that a remote temperature controller is not used.
It will be necessary to check and if required to adjust the preset outlet temperature setting of the continuous
flow water heater when:
• it is installed as an in-series gas booster to a solar water heater
• it is an existing continuous flow water heater and a solar water heater is then installed.
Notes:
• Consideration must be given to the delivery temperature to any ablution and public areas such as a
bathroom, ensuite or public amenities. Refer to
Two Temperature Zones Using A Temperature Limiting Device"
• The 875 series water heater, marked "THIS APPLIANCE DELIVERS WATER NOT EXCEEDING 50°C
IN ACCORDANCE WITH AS 3498" on the front panel, must not be installed as an in-series gas booster
to a solar water heater, as water temperature greater than 50°C can be delivered from the water heater
contravening its compliance to Australian Standard AS 3498.
