When it is used as a basement model, a drop duct and instructions are available. Series C and D 393 Counterflow boxes are not interchangeable with the 394 Counterflow boxes. Before beginning installation, read these instructions carefully. When making a Counter-Flow or Basement installation, also read the separate instructions furnished with the additional equipment required. Install the furnace in accordance with the requirements of the local utility or authority having jurisdiction. The installer is referred to the American Standard “Installation of Gas Appliances and Gas Piping,” ASA Z21.30-1964, as a sound and practical guide to be followed when making the installation. INSPECTION Check the power supply available to be sure it agrees with the information on the wiring diagram and the blower motor in the furnace. Check the gas specification on the A.G.A. rating plate to be sure that the type of gas for which the unit is equipped is the same as the gas supply available. FILTERS When the furnace air distribution system is used for cooling, it is recommended in certain instances that the throw-away filters be discarded and the permanent type, multi-velocity filters be substituted. The following table gives the air flows above which these high velocity filters should be used. c: Throw-away Filters Permanent Filters Air Flow - cfm 50 1000 --- 80 1000 1785 100 1000 1785 125 1420 2020 Air Flow - cfm Leave these instructions near the furnace. Permanent filters are not required on Size 50.
