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.
