Safe Tray
Where damage to property can occur in the event of the water heater
leaking, the water heater must be installed in a safe tray. Construction,
installation and draining of a safe tray must comply with AS/NZS 3500.4
and all local codes and regulatory authority requirements. AS/NZS 3500.4
also has particular requirements when a safe tray must be installed.
Flashing Kit
When attaching a Flashing Kit to the water heater jacket, we recommend
the use of self-drilling screws with a maximum length of 12 mm. An
effective seal must be achieved where the screw penetrates the jacket. The
Flashing Kit must not be installed within a 100 mm wide vertical strip either
side of the cold water inlet, hot water outlet and pressure temperature relief
valve. Flashing Kits are available from Aquamax and if required are
purchased as a separate kit. The kit part number is:
Model G270VE
Flashing Kit Part No. AQ1184105
Note: If the water heater or storage cylinder is damaged as a result of
installing the Flashing Kit, any resultant faults will not be covered by the
Aquamax warranty.
Water Supplies
Mains Water Supply
Where the mains water supply pressure exceeds that shown in the table
below, an approved pressure limiting valve is required and should be fitted
after the stop cock and before the non return valve as shown in the ‘Cold
Water Supply Plumbing Arrangement’ diagram on page 25.
Model G270VE

Tank Water Supply
If the water heater is supplied with water from a tank supply and a pressure
pump system is not installed, then the bottom of the supply tank must be at
least 1 m above the highest point of the hot water plumbing system,
