Features
Factory Installed Control Sections
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 be so 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
means of an electric motor and axial flow fan blade.
Heaters shall be recessed type and mounted flush with the finished
ceiling. The return grille assembly shall be constructed of a one
piece heavy gauge steel with 1/4” slots for return air and concentric
rings for uniform air discharge. Grille assembly shall be attached to
chassis by tamper-resistant (allen head) machine screws. All parts
of enclosure shall be heavy gauge steel, zinc coated both sides and
finished in neutral off white powder coat paint.
Enclosure shall be constructed of 1/6” x 3/8” rounded edge
horizontal steel louvers which shall be spaced for maximum opening
of 5/16”. Louvers shall be welded at every intersection to evenly
spaced 1/8” diameter vertical members. Discharge grille to have
concentric rings for uniform air discharge. Grille assembly shall be
attached to chassis by tamper-resistant (allen head) machine screws.
All part of enclosure shall be heavy gauge steel, Zinc coated both
sides and finished in neutral off white colored powder coat finish.
Motor shall be permanent lubricated, unit bearing, totally
enclosed, impedance protection. Motors shall operate at no more
than 1300 RPM and shall be same voltage as the heater.
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 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.
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.
Heaters shall be ETL listed.
