NOTE: Options shown in a bold-italic font require that reducers be used at both ends. These extra large sizes are to allow for better condensation removal in long steam runs. These sizes do not permit the use of hose couplings to connect either humidifier or distributors.

NOTE: Insulate all copper or stainless steel steam lines with minimum one inch high temperature insulation.
