When using units with 20--, 24--, and 30--kW electric heaters, maintain a 1--in. (25 mm) clearance from combustible materials to discharge
plenum and ductwork and maintain a distance of 36 in. (914mm) from the unit. Use an accessory downflow base to maintain proper clearance
on downflow installations. Use flexible connectors between ductwork and unit to prevent transmission of vibration. When electric heater is
installed, use heat resistant material for flexible connector between ductwork and unit at discharge connection. Ductwork passing through
unconditioned space must be insulated and covered with vapor barrier
