x 90° (1-7/8″ x 4″) siphon and the 3/4" NPT x 1/4″
FPT hex bushing.

in Figure 43. The safety valve is installed in the tee
provided for blowoff piping.
Safety valve discharge piping must be piped
to within six (6) inches of floor or to floor drain
to eliminate potential of severe burns. Do not
pipe in any area where freezing could occur. Do
not install any shut-off valves, plugs or caps in
discharge piping.
La tuyauterie de décharge de la soupape de
sécurité doit être raccordée à moins de six (6)
pouces du plancher ou au drain de plancher
pour éliminer le potentiel de brûlures graves. Ne
pas installer de tuyaux dans des zones où le gel
pourrait se produire. Ne pas installer de vannes
d'arrêt, de bouchons ou de capuchons dans la
tuyauterie de refoulement.
