INSTALLATION ELECTRIC SHOCK HAZARD. Disconnect all power before installing or servicing heater. Failure to do so could result in personal injury or property damage. Heater must be installed by a qualified person in accordance with the National Electrical Code, NFPA 70. High heating efficiency, low sheath temperatures and long heater life result when electric heaters are properly installed. INSTALLATION – CLAMP-ON 1. Clamp strip heaters securely, along their entire length, to smooth metal surface

mounted to a heavy gauge metal terminal box. Due to the various options and materials available, check the IMPORTANT — Observe at least one complete heating cycle nameplate attached to the heater terminal box with the catalog operation before leaving the installation. number designation system on page 7 before installing to insure the heater you received conforms to your specification. © 2010 Chromalox, Inc.

GENERAL Type CVEP Convection Heaters are designed for use in Class I, Div I hazardous environments. Units without control options are suitable for areas classified as Groups B, C & D. Units with built-in controls can be supplied for groups C and D or B, C and D. Refer to classification stamped on heater nameplate. FIRE/EXPLOSION HAZARD. To prevent ignition of hazardous atmospheres, this heater should not be installed in areas where vapors or gases having an ignition temperature less than 280°C (

WARNING: Hazard of Fire. Keep electrical cords, drapes, rugs and other furnishings away from the heater. The normal operating temperatures of cabinet convectors are relatively high. Proper operation requires free circulation of room air through the heating element. Installation Wall 1. Unpack the heater from the carton and remove the front panel. Note: The front panel screws are recessed at the bottom of the top front panel at each end of the heater. (Figure 2) Remove top front panel by pulling

WARNING: Hazard of Fire. When the floor is to be finished in carpet, allow clearance under the heaters and corners for carpet installation.
