Product Specifications

Contractor shall supply and install heavy duty wall mounted forced air electric heaters of the wattage, voltage and phase as specified. 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 peripheral area of the heater across and through the element which shall then 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 to extend no more than 1-1/2” from the finished wall or surface mounted to extend no more than 5-3/4” from the finished wall or semi-recessed type to extend no more than 3-1/2” from finished wall or semi-recessed type to extend no more than 2-1/2” from finished wall.

Heater front shall withstand 10.8 ft. lbs. impact and 400 lbs. static force applied to an 8 sq. in. area at center grille location with less than 1/16” permanent distortion. The combination return and supply grille assembly shall be constructed of 1/16” x 3/8” rounded edge horizontal steel louvers which shall be spaced for maximum opening of 1/4”. Louvers shall be welded at every intersection to three evenly spaced 1/16” diameter vertical members and completely framed in a heavy gauge natural anodized Aluminum extrusion. Front assembly shall be attached to the chassis by hidden tamper-resistant (Allen-head) machine screws. All other parts shall be 16 Gauge steel Zinc coated, both sides finished in a high gloss or bronze colored baked powder coat finish.

Motor shall be a permanently lubricated unit bearing, totally enclosed shaded pole type with impedance protection. Motors shall operate at no more than 1400 RPM and shall be same voltage as the heater. A protective shield shall surround the motor to separate return air from heated air.

Heaters shall have a rating of 245 CFM at 660 F.P.M. with a maximum temperature rise of 73°F.

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 the 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.
