ABOUT YOUR WATER HEATER

GOING ON HOLIDAYS
It is not necessary to switch off the electrical supply at the power outlet to the water heater if you are going
away. However, if it is necessary to switch off the power to the water heater, refer to “To Turn Off The Water
Heater” on page 8. If the power to the water heater is switched off and there is a risk of freezing, then it is
necessary to drain the gas booster (refer to “Draining the Gas Booster Water Heater” on page 9).
DRAINING THE GAS BOOSTER WATER HEATER
 Turn off the water heater (refer to “Turn Off The Water Heater” on page 8).
 Open a hot tap (preferably the shower outlet).
 Unscrew the two drain plugs, one each at the cold water inlet and hot water outlet, on the underside of
the gas booster.
Water will drain from the gas booster.
 When water stops flowing from the gas booster, close the hot tap.
Note: It is recommended not to screw the drain plugs back in, until the water heater is to be turned on again.
HOW DO I KNOW IF THE WATER HEATER IS INSTALLED CORRECTLY?
Installation requirements are shown on pages 19 to 27. The water heater must be installed:
 by a qualified person, and
 in accordance with the installation instructions, and
 in compliance with Standards AS/NZS 3500.4, AS/NZS 3000, AS 5601 or AS/NZS 5601.1, as applicable
under local regulations, and all local codes and regulatory authority requirements.
In New Zealand, the installation must also conform to Clause G12 of the New Zealand Building Code.
Warning: Temperature controllers must not be fitted to an in-series gas booster as part of a solar water
heater system because water at a temperature much higher than the controller setting can be delivered.
