* Natural Gas boilers require a Propane conversion kit (see page #3-2, Table 9) to be ordered separately if converting a Natural Gas boiler to Propane. Propane (LP)
boilers require a Natural Gas conversion kit (see page #3-2, Table 9) to be ordered separately if converting a Propane boiler to Natural Gas.
† boilers are shipped with 30 psig pressure relief valve
