IMPORTANT: While this electrical data is presented as a guide, it is important to electrically connect properly size fuses and conductor wires in accordance with the National Electrical Code and all existing local codes. Manual 2100-324 Page 3 GENERAL INSTRUCTIONS IMPORTANT The equipment covered in this manual is to be installed by trained, experienced service and installation technicians. All duct work, supply and return ducts, must be properly sized for the design air flow requirement of the e

A minimum of twelve inch elevation is recommended, while greater elevation may be required for areas of high snow accumulation. Poured concrete, steel framework, brick, cement block, etc., can be utilized to construct a suitable raised mounting platform. See Figure 6. DUCT WORK Refer to Tables 4, 5 and 5A when designing duct work for maximum static pressure available with the specific model and heater package being installed. Unit duct work is suitable for 0” clearance to combustible materials.
