appliance is damaged because the PTR valve safety device has
been blocked, it is not covered by warranty.

• If the appliance is to be tted in a room or location where the
ambient temperature is higher than 35°C, sucient ventilation

must be provided.

• It is compulsory to t a tray/ sump below the water heater if

mounted in a suspended ceiling, under a roof or above living area.
Position the appliance where it can be accessed.

Mandatory installation of a safety device in a frost free location (or

any other new device which limits the tank pressure) to 850 kPa

according to the nominal pressure, with a size of 3/4’’ on the input

of the water heater, respecting the local regulations .

Operate regularly the discharge of safety device to prevent scaling and

check that it is not blocked.

To drain the device switch o the power and the supply of cold water,

open the hot water faucets and manipulate the safety valve.

The pipes used must support 1 MPa (10 bar) and 100°C.

Cold Water Inlet

Cold water piping should be provided with a 350 – 500 kPa Pressure

Limiting Valve at the point of cold water connection to the
water heater. In addition to the Pressure Limiting Valve, it is a
requirement of AS 3500.4 & NZBC G12 that both a Stop Valve and a
Non Return Valve are installed upstream of the Product.



No parts (stop valve, pressure reducer, etc.) must be placed between the

pressure limiting valve and the cold water inlet of the water heater,
apart from a copper pipe.



Note: Since limited water discharge from Pressure Limiting Valve is

normal in the heating operation, the discharge pipe needs be
connected to external drain.

Hot Water Outlet

Where a maximum hot water delivery temperature is specied by local,

state or federal regulations, a tempering valve shall be installed at
the hot water outlet, as required.

The included specied Pressure & Temperature Relief valve must

be installed as shown in the schematic. The PTR valve should
be connected to a drain point to accommodate discharge as a
