At the time of manufacturethis water heater was provided with a

AutomaticGas ShutoffDevicesfor Hot Water SupplySystems, and the latest edition of ANSI Z21.22 and the code require- mentsof ASME. If replaced,the valvemustmeet the require- mentsof localcodes,but not lessthan a combinationtempera- ture and pressurerelief valvecertifiedas meodngthe require- mentsfor ReliefValvesand AutomaticGas ShutoffDevicesfor Hot Water SupplySystems,ANSI

The valve mustbe m_(ed with a maxmmumset pressurenot to exceed the marked hydrostaticworking pressure of the water heater (150 IbsJsqin. .) and a dischargecapacitynot less than the water heater input r_e asshownon the modelrating plate. (Electric heaters - watts dividedby 1000 x 3415 equal BTU/Hr. rate.)
