2.02 ELECTRIC PROPELLER UNIT HEATERS

A. Heating Elements: Nickel-chromium heating wire element; free from expansion noise and 60-Hz hum; embedded in magnesium oxide, insulating refractory; and sealed in high-mass steel or corrosion-resistant metallic sheath with fins no closer than 0.16 inch. Element ends are enclosed in terminal box. Fin surface temperature does not exceed 550 deg F at any point during normal operation.

B. Heater Circuit Protection: One-time fuses in terminal box for overcurrent protection and limit controls for overtemperature protection of heaters.

C. Fan and Motor: Direct-drive propeller fan and manufacturer's standard motor. Motors sized 1 hp and less include motor overload protection.

D. Wiring Terminations: Match conductor materials and sizes indicated.

E. Discharge Configuration: Horizontal discharge with horizontal, adjustable louvers.

F. Optional Accessories: Include the following:

1. Wall thermostat.

2. Safety-switch disconnect on cover of terminal box.

3. Mercury contactors.

4. Fan-delay relay.

2.03 ELECTRIC CABINET UNIT HEATERS

A. Description:

1. Semi-recessed, ceiling-mounted cabinet.

B. Heating Elements: Nickel-chromium heating wire element; free from expansion noise and 60-Hz hum; embedded in magnesium oxide, insulating refractory; and sealed in high-mass steel or corrosion-resistant metallic sheath with fins no closer than 0.16 inch (4 mm). Element ends are enclosed in terminal box. Fin surface temperature does not exceed 550 deg F (288 deg C) at any point during normal operation.

C. Heater Circuit Protection: One-time fuses in terminal box for over-current protection and limit controls for over-temperature protection of heaters.

D. Fan and Motor: Centrifugal blower, direct driven by a single-phase, 2-speed electric motor with inherent overload protection and resilient motor/fan mount.

E. Wiring Terminations: Match conductor materials and sizes indicated.

G. Optional Accessories: Include the following:

1. Disconnect switch.

2. Mercury contactor.

3. Fan-delay relay.

H. Finish cabinet with manufacturer's standard enamel, color as selected by Owner’s Representative.

2.04 ELECTRIC WALL HEATERS:

A. General: Provide electric wall heaters with architectural styling for exposed or recessed application.

B. Heater Assembly: The heater assembly which fits into the back box shall consist of a fan panel upon which is mounted all of the operational parts of the heater.

C. Heating Element: The heating elements shall be of the non-glowing design consisting of a special resistance wire enclosed in a steel sheath to which steel plate fins are copper brazed. It shall be warranted for 5 years.

D. Fan and Motor: Fan shall be five bladed aluminum. Fan motor shall be totally enclosed.

E. Fan Delay Switch: Fan control shall be of bi-metallic, snap-action type and shall activate fan after heating element reaches operating temperature. The fan shall continue to operate after the thermostat is satisfied and until the heating element is cool.

F. Thermostat: The tamper-proof thermostat shall be of the bimetallic snap-action type with enclosed contacts. It shall be completely concealed and reactive behind the front cover to become tamper proof.

G. Thermal Cutout: A thermal cutout shall be built into the system to automatically shut off the heater in the event of overheating and reactivate the heater when temperatures return to normal.

H. Disconnect Switch: A double-pole, single throw disconnect switch shall be mounted on the back box for positive disconnect of power supply. It will be completely concealed behind the front grid panel.

I. Back Box: The back box shall be designed for duty as a recessed rough-in box in either masonry or frame installations, and is also used with the surface mounting box in surface mounted installations. The back box shall be 20 gage cold-rolled steel and shall contain knockouts through which power leads are brought.

J. Front Panel: The front panel shall be of the bar grille type and shall be constructed of 16 gage cold-rolled steel, welded into a uniform grille to direct the warmed air toward the floor. The front grille shall be surrounded by a decorative satin-finish aluminum “picture” frame.

K. Three Piece Design: The heater shall be made up of a back box, a heater assembly and a front panel. Provide surface mounting kit where indicated.


A. Examine substrates and supports to receive unit heaters for compliance with requirements for installation tolerances and other conditions affecting performance of units. Do not proceed with installation until unsatisfactory conditions have been corrected.



3.02 INSTALLATION

A. Install heaters as indicated, according to manufacturer's written instructions and NFPA 90A.

B. Connect heaters and components to wiring systems and to ground as indicated and instructed by manufacturer. Tighten connectors and terminals, including screws and bolts, according to equipment manufacturer's published torque-tightening values for equipment connectors. Where manufacturer's torque requirements are not indicated, tighten connectors and terminals according to tightening requirements specified in UL 486A.


A. Testing: After installing unit heaters and after electrical circuitry has been energized, demonstrate product capability and compliance with requirements.

B. Remove and replace malfunctioning units with new units and retest.
