The factory fitted temperature & pressure relief valve at the top of the

cylinder is a safety device to back-up the thermostat(s) and thermal cut-

out(s). It works by sensing an excess in water temperature or pressure and

releasing the hot water into a discharge tundish and drain.

The cylinder will only work in the vertical position. The inlet pipe needs to

deliver cold water to the bottom of the tank. When water is heated it expands.

To accommodate this increase in volume an expansion vessel is provided. A

cold water combination valve is also provided in two pieces, loose jointed for

ease of installation. These comprise a combined line strainer/pressure

reducing valve and core non-return valve/expansion relief valve.
