5.5 Safety Relief Valve

AM units come equipped with a safety relief valve on each factory installed module. Boilers are
supplied with 50 PSI pressure relief valves. If a higher or lower rated PRV is required it must be
field supplied and installed.
Pipe the discharge of the safety relief valve(s) (Figure 5-1) to a suitable drain to prevent injury in
the event of pressure relief. Each relief valve must have its own discharge piping, be piped to
within 12" of the ground, and not be combined with any other piping all the way to the point of
discharge into a drain. Provide piping that is the same size as the safety relief valve outlet.
