Please find necessary pressure values in the below Table 3. For proper safety valve operation, a backflow
valve (Figure 4) must be mounted on the inlet pipes, preventing spontaneous heater draining and hot water
penetrating back into the water main. We recommend that the hot water distribution from the heater was
as short as possible to minimise heat losses. At least one demountable joint must be mounted between
the tank and every supply pipe. Adequate piping and fittings with sufficiently dimensioned maximum
temperature and pressure values must be used.
