ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property dam- age. Heater must be installed by a qualified person in accordance with the National Electrical Code, NFPA 70.
1.Clamps — Heaters are mounted by means of the mounting clamp and 3/8” bolt assembly which is used as shown in Figure 2. Clamp assembly may be attached to heater by sliding over end or by snapping over top of extruded frame section at any point along its length (see Figure 3). For proper heater support, the maximum distance between clamps must not exceed 48”. On
2.Mounting Holes — When heaters are mounted adjacent to each other in the same plane, note that distance between mount- ing holes on framing to support heaters will be 311/16” minimum. When heaters are not in the same plane, i.e., set at an angle to one another, distance between mounting holes in framing will be either greater or less than 311/16”.
3.Framing — Where an extensive installation is being made, the use of continuous slot metal framing manufactured by several concerns will be of assistance in saving time and money. The framing is reusable.
4.Reflector Spacer Sheets — Where heaters are not mounted side by side (see Figure 4), reflector spacer sheets can be used between heaters. These reflector spacer sheets and companion reflectors consisting of an extruded aluminum housing with reflector sheet and mounting clamps are available. Check factory.
5.Insulation — Where unusually high work temperatures are encountered, it may be desirable to insulate backs of heaters with
6.Ventilation — Where solvents, water, etc. are being evaporat- ed from work in process, it is necessary to provide substantial quantities of ventilation air to carry away the resulting vapors.

Hazard of Fire. In the case of solvents of an explo- sive nature, ventilation air must be in sufficient vol- ume to dilute the solvent vapor so that explosive mixtures cannot occur. In order to comply with the standards of safety required by the insurance com- panies, ventilation protection and other facilities must be in accordance with National Fire Protection Association Bulletin No. 86, entitled “Standard for Class A Ovens and Furnaces”. This bulletin may be obtained from the Association at 1 Batterymarch Park, Quincy, MA 02269.
