Water can drip from the safety valve through the drain pipe; the pipe must be freely open to
the atmosphere, placed vertically and shall be in an environment free of temperatures below
freezing. When draining the heater, use a drain valve. You must first close the water supply
to the heater. Required pressures are in Table 2 below.. To ensure correct operation the
safety valve must be mounted on the inlet piping return valve, preventing spontaneous
heater draining and hot water penetrating back into the water main..
Required pressures - Table 2 - We recommend that the hot water distribution from the heater was as short
as possible to minimise heat losses.
