GENERAL FIRE/EXPLOSION HAZARD. This heater is not intended for use in hazardous atmospheres where flammable vapors, gases, liquids or other combustible atmospheres are present as defined in the National Electrical Code. Failure to comply can result in personal injury or property damage. 1. Heater construction characteristics — A. Alloy sheathed tubular elements, .475” diameter B. Steel flange C. Stainless steel support construction D. High temperature alloy terminals and connections E. Replaceable individual heating elements F. Wiring terminals located outside the heated zone 2. Maximum Temperatures — Types ADH and ADHT process air heaters can generally be used at the following maximum temperatures shown, provided the minimum air velocity is maintained uniformly through the heater. Air Velocity (Ft./Sec.) Max. Outlet Air Temp. (°F) ADH ADHT 4 800 1050 9 800 1100 16 800 1150 25 800 1200 36 800 1200 CAUTION: Do not energize heater in air with a velocity less than 1 Ft. Per Second. 3. The heater may be bolted to the duct with the terminal housing and flange at the top, at either side or at the bottom. 4. Several heaters may be mounted in tandem so long as proper controls are used to limit the maximum temperature attained. 5. Installation with duct transitions in some air distribution systems, the duct heater may be considerably larger than the duct- work and the duct area must be increased by a sheet metal tran45° 45° Max 30" Max 30° Duct HeaterAir Flow 4 Ft. Min. 4 Ft. Min.Figure 3 sition. The slope of the transformation piece on the upstream side of the equipment is limited to 30° as indicated in Figure 3. On the leaving side, the slope should not be more than 45°. 6. Use moisture proof terminal cover in atmospheres bearing corrosive fumes or excessive moisture. 7. Use explosion resistant heaters in explosive atmospheres and reduce current rating to elements. 8. Gas tight design — Achieved by the use of threaded fittings with fiber washers to attach heating elements to flange — pre vents leakage of ducted air into terminal housing. 9. Overtemperature protection — Thermocouple fastened to the element sheath surface and wired to a terminal block can be provided for accurate overheat protection (standard on ADHT models). 10. Flange mounting gasket — Packed separately with each duct heater to minimize air leakage between the flange and air duct. Refer to Table B and Figure 4.
