COMMISSIONING
All water heaters are tested and adjusted before dispatch from the factory, however further adjustments
may become necessary because of local conditions.
It is necessary to check and if required adjust the preset outlet temperature of the water heater.
PRESET OUTLET TEMPERATURE
The preset outlet temperature of the gas booster water heater must be set at 60
°
C for the system to
operate correctly. The factory default preset outlet temperature is 50
°
C for Australian models with a
manufacture date before 2007 and 60°C for Australian models with a manufacture date of 2007 or later.
New Zealand models have a factory default preset outlet temperature of 55°C. It will be necessary to
check and if required adjust the preset outlet temperature for a new installation of a gas booster water
heater.
Note:
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 16 and to the
schematics of
“Two Temperature Zones Using A Temperature Limiting Device”
on page 17.
