CHROMALOX ELECTRIC HEATING ELEMENTS FOR OVEN HEATING – AIR DUCTS

The electric heating element(s) supplied herein are ruggedly con- structed and if properly installed, operated and maintained, are designed for long life and dependable, trouble-free service.

GENERAL

Temperature regulating and temperature limiting controls are recommended to be used with electric heaters to control the heating process and safeguard the electric heaters from excessive tempera- tures that can damage heaters.

FIRE HAZARD. Since heaters are capable of devel- oping high temperatures, extreme care should be taken to:

A.Avoid mounting heaters in an atmosphere containing com- bustible gases and vapors.

B.Avoid contact between heaters and combustible materials.

C.Keep combustible materials far enough away to be free of the effects of high temperatures.

INSTALLATION

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.

High heating efficiency, low sheath temperatures and long heater life result when electric heaters are properly installed.

INSTALLATION – OVEN HEATING

1.When mounting the strip heaters vertically, locate the terminals at the bottom or cooler parts of the oven. Allow for expansion and contraction by loosely bolting the top mounting tab. Secure the bottom tab firmly.

2.In a forced air system, the width of the strip should be parallel to the direction of air flow.

3.For horizontal installation of strips, the tab on the terminal end should be firmly connected and the opposite end loosely con- nected to allow for expansion and contraction.

4.Mount strips on edge in horizontal installation across the bottom and along the sides on the oven, allowing 3” minimum air space between the heaters and the bottom of the oven and 1” from the oven wall to allow for proper circulation of heated air. For large ovens, allow a 6” minimum clearance.

5.In horizontal mounting, install a protective screen or grill above the strips at the bottom of the oven.

6.Support long iron sheathed strips on 36” centers and chrome steel sheathed strips on 24” centers to prevent sagging.

INSTALLATION – AIR DUCTS

1.Locate protective thermostat on downstream side of heaters near the top of the duct and close to the heated portion of the heaters.

2.Mount heaters with terminals at the duct bottom to prevent over- heating.

3.Where condensation, spray, oil or fumes are present use seam- less finstrips, type SSEF, with the terminals placed outside of the air duct.

4.As a safety feature in advent of abnormal temperatures, it is sug- gested to use a thermal cutout in conjunction with thermostatic control.

WIRING

ELECTRIC SHOCK HAZARD. Any installation involv- ing electric heaters must be performed by a quali- fied person and must be effectively grounded in accordance with the National Electrical Code to eliminate shock hazard.

1.Electric wiring to heating elements must be installed in accor- dance with National Electrical Code or local electrical codes by a qualified person.

2.Temperatures at heater terminals may require use of high-tem- perature wire. Check factory for recommendations.
