Approvals
Standard Features
Heaters shall be low profile (3″ x 5 1/2″, 5″ x 7″, 5″ x 14″) and available in lengths from 28 inches through 10 feet.
Enclosures shall be 16-gauge, furniture quality steel with reinforced, all welded construction; designed to withstand heavy-duty commercial and institutional use.
Enclosures shall be chemically-treated to resist corrosion. Finish shall be mar and temperature-resistant to retain contemporary appearance throughout years of rough use.
For safety, the electric heating bank shall consist of metal sheath heating elements. The elements shall have a copper clad steel sheath for strength and corrosion resistance, and aluminum fins for faster heat transfer.
One, two, or three, low density elements shall be installed side-by-side on the same plane to uniformly warm all incoming air. Elements shall be center-anchored and shall float freely on each end through nylon bushings for quietness.
Discharge louvers shall be an extruded aluminum bar grille painted bronze brown to contrast with the neutral grey front finish. The bar grille with contrasting finish shall ensure a clean, decorative finish.
A 1/4-inch mesh screen shall be installed beneath the discharge grille to deter the insertion of foreign objects.
Optional built-in controls shall include single-pole, double-pole, or two-stage thermostats, power on/off switch, transformer relay and power relay. The thermostat shall be capable of controlling multiple units on a pilot duty circuit. (Observe the control limitations indicated.) Thermostat adjustment shall be with a thin-bladed screwdriver through the discharge louvers and shall be considered tamper-resistant.
An automatic reset thermal overheat protector shall run the full-length of the heater and shall turn off heating elements should overheating occur at any point along heating length. Overheat protector shall restore operation automatically when cause of overheating is removed. Heaters shall be designed with a built-in prewired race-way to enable multiple unit wiring from one feeder source.
Back panel shall be one piece heavy gauge painted steel, completely finished, and shall be suitable for mullion-to-mullion mounting in front of a glass curtain wall.
28-inch control sections, finished to match the heating units, shall be available with factory built-in mercury contactors, circuit breakers, control transformer, P.E. switch, or SCR controls. This control section shall also be furnished blank, as an optional accessory, for field installation of controls.
All heaters and electrical accessories shall be labeled by Underwriters’ Laboratories, Inc.
Accessories shall include end caps, blank sections (28″ blank sections shall be designed for field-cutting), inside and outside corners, splice plates, and telescoping filler sections. All accessories shall be completely enclosed to enable the installer to pull standard wiring from heater to heater through the accessories.
