PRESET OUTLET TEMPERATURE SETTING

The factory preset outlet temperature setting of the water heater is:

• 884 series 60°C – AU, 55°C – NZ

• 886 series 50°C

If a Deluxe 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 Setting 884 series 886 series

Kitchen controller connected 60°C – AU, 55°C – NZ 50°C

Bathroom controller only connected 50°C 50°C

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: 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 gas booster to a solar water heater, it can

satisfy this AS 3498 requirement provided it is energised, the booster preset outlet temperature setting is

70°C or higher and 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 “Hot Water Delivery” on page 38 and to “Schematics of

Two Temperature Zones Using A Temperature Limiting Device” on page 39.

• The 886 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 AS 3498.
