Tempering Valve – Rheem Plus Models
A non adjustable valve that mixes hot and cold water to provide an outlet water
temperature of 48ºC +/- 1.5ºC.
Cold Water connector – Rheem Plus models
A three way fitting which the plumber connects the cold water supply to. This fitting then
diverts water to both the storage cylinder and to the cold water inlet of the tempering valve.
Eurosit 630 Gas Control
The gas control is a multi-functional single knob gas control. It is gas type specific,
designed for Natural, Propane or TLP Gases. The control is factory set and not field
serviceable or gas type convertible.
The gas control is manufactured without the temperature probe and Over Temperature
Switch (ECO) enclosed in a sheath.
The sheath (called an adapter) is a separate item and is screwed into the cylinder during
manufacture. A slot in the head of the adapter is aligned in the horizontal position to allow
the snap on bracket at the rear of the gas control to be located positively. This design
allows the gas control to be replaced without the need to drain the water heater.
Note: The only time the adapter needs to be removed is in the event of a leak developing
at the cylinder connection or in the adapter itself. In either case the water supply must
be isolated and pressure relieved from the cylinder prior to removal or replacement.
In the event of an adapter replacement, use a 27mm socket to prevent damage to
the slot. Apply thread-sealing tape and tighten so that the slot is horizontal with a
minimum of 2 threads or a maximum of 4 threads protruding from the cylinder
fitting.
Eurosit Gas Control (Old Style) Eurosit Gas Control (New Style)
Over Temperature Energy Cut Out (ECO)
A temperature-sensing device in combination with the gas control, that automatically cuts
off the supply of gas to prevent excessive water temperature occurring. This device will
reset automatically once temperatures have fallen to a safe level, allowing the pilot to be
relit. The cause of operation must be determined.
