* Natural Gas boilers / water heaters require a Propane conversion kit (see page #3-2, Table 10) to be ordered separately if converting a Natural Gas boiler / water
heater to Propane. Propane (LP) boilers / water heaters require a Natural Gas conversion kit (see page #3-2, Table 10) to be ordered separately if converting a
Propane boiler / water heater to Natural Gas.
† boilers / water heaters are shipped with 30 psig pressure relief valve
