Contractor shall supply and install heavy duty ceiling mounted forced air
electric heater(s) of the wattage, voltage and phase as indicated on the plans. The
heater shall so be designed to provide an even distribution of heated air to the space to
be heated by drawing return air in the periphery of the heater, across and through the
element and be discharged from the center section of the heater by mean of an electric
motor and axial flow fan blade.
Motor: Motor shall be permanent lubricated, unit bearing, totally enclosed
shaded pole type with impedance protection. Motors shall operate at no more than
1300 RPM and shall be same voltage as the heater.
Performance: Heaters shall have a rating of 425 CFM at 710 F.P.M. with a
maximum temperature rise of 44°F and 63.9 DB RE 10 12 Watt.
Element: Element assemblies shall consist of two or three corrosion resistant
steel sheathed type elements mechanically bonded to common corrosion resistant
steel fins. Each sheathed element shall consist of helically coiled Nickel Chromium
alloy resistant wire completely embedded in and surrounded by Magnesium Oxide,
enclosed and wedged into corrosion resistant steel sheaths. Elements shall have 2”
cold conductor pins extending into sheath and shall have a density of no more than 60
watts per inch.
Thermal Overload: Heaters shall be equipped with a “manual reset” thermal
overload which disconnects elements and motor in the event normal operating
temperatures are exceeded. For safety, if opened due to abnormal temperature,
thermal overload shall remain open until manually reset. Automatic reset thermal
overloads which allow the element to continue to cycle under abnormal conditions
will not be accepted.
Approval: Heaters shall be ETL listed.
Commercial and Institutional Applications: Use in - vestibules, entrance
ways, lobbies, rest rooms and small office and guard building applications.
