COMMISSIONING

PRESET OUTLET TEMPERATURE

The factory preset outlet temperature of the water heater is:

871 series (pre 2007 manufacture date) 50°C

871 series (from 2007 manufacture date) 60°C

875 series 48°C

If a temperature controller is connected to the water heater, this will override the preset outlet temperature

setting and the maximum outlet temperature will be:

Maximum Outlet Temperature

871 series

875 series

Kitchen controller connected

60°C

48°C

Bathroom controller only connected

50°C

48°C

It is usually not necessary to check or adjust the factory preset outlet temperature of the water heater, unless

the customer has a particular requirement for this to be done or it is to be installed as a gas booster to a

solar water heater.

Gas Booster for a Solar Water Heater

Where an 871 series water heater is installed as a gas booster to a solar water heater, the preset outlet

temperature must be set at 60 C for the system to operate correctly.

It will be necessary to check and if required to adjust the preset outlet temperature of the continuous flow

water heater when:

it is installed as a gas booster as part of a solar water heater installation

it is an existing continuous flow water heater and a solar preheat 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 45 and to “Schematics of 2

Temperature Zones Using A Temperature Limiting Device” on page 46.

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

water heater 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.
