PRESSURE & TEMPERATURE RELIEF VALVE

The Pressure & Temperature relief valve is supplied loose with the water heater. The

valve rating is:

• 25 to 160L Models

• 250 to 400L Models -

The relief valve must be installed directly into the top socket marked "RELIEF VALVE".

The drain line from this valve must be installed in a continuously downward direction in a

frost free ambient position with the discharge end left open to atmosphere permanently.

The Pressure & Temperature Relief Valve supplied with the water heater is not sufficient to

enable connection of the water heater to supplementary energy sources such as solar

panels or slow combustion stoves (refer AS/NZS 3500.4.2 for guidance on these types of

installations)

Note: Plugs are supplied with the water heater to plug off the fittings that are not required.

Ensure that a sealing material is applied to the plugs for a leak tight fit.
