PRESET OUTLET TEMPERATURE SETTING
The factory preset outlet temperature setting of the water heater is:
874 series
876 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 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.
Refer to "To Check or Adjust the Preset Outlet Temperature Setting"
adjust the preset outlet temperature setting of the water heater.
In-series gas booster for a Solar Water Heater
Note: 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 876 series water heater, marked "THIS APPLIANCE DELIVERS WATER NOT EXCEEDING 50°C

to a solar water heater, as water temperature greater than 50°C can be delivered from the water heater
contravening its compliance to AS 3498.
