ARCHITECT’S & ENGINEER’S SPECIFICATIONS** The heating equipment shall include a ceiling mounted QFF electric automatic fan-forced heater suitable for large area heating as manufactured by Berko, A Marley Engineered Products Brand, Bennettsville, SC. The heater shall be designed for ceiling surface, recess or T-Bar mounting. Heaters shall be UL Listed. HEATER ASSEMBLY: The heater assembly, which fits in the back box, shall consist of a fan panel upon which is mounted all of the operational parts of the heater. HEATING ELEMENT: The heating element shall be of the non-glowing design consisting of 80/20 NiCh resistance wire enclosed in a steel sheath to which plate fins are copper brazed. It shall be warranted for 5 years. FAN AND FAN MOTOR: The fan shall be five-bladed aluminum. The fan motor shall be totally enclosed. 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. THERMAL CUTOUT: A thermal cutout shall be built into the system to shut off the heater in the event of overheating. 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 com-
pletely concealed behind the face-plate. BACK BOX: The back box shall be designed for duty as a recessed rough-in box either masonry or frame installations, and is also used with the surface mounting frame in surface mounting installations. The back box shall be 20-gauge galvanized steel and shall contain knockouts through which power leads are brought. FACEPLATE: The louvered faceplate shall be of 14 gauge cold-rolled steel, phosphatized, then electrostatically painted Navajo White by a powder coat process. A 1/4-inch mesh screen shall be installed beneath the faceplate to deter the insertion of foreign objects. The face plate shall be secured to the heating unit with tamper-resistant screws. THREE-PIECE DESIGN: The heater shall be made up of a back box, a heater assembly and a faceplate. OPTIONS: THERMOSTAT: The optional tamperresistant thermostat shall be of the bi-metallic, snap-action type with enclosed contacts. It shall be completely concealed behind the faceplate to become tamperresistant (QFFT1 or QFFT2). LOW VOLTAGE TIME DELAY RELAYS: 24 volt and 120 volt low voltage time delay relays are available as optional equipment to control 208, 240 or 277 volt heaters (with an external supplied 24 or 120 volt control circuit) in conjunction with central
energy control systems. The built-in thermostat can then be used as one of the thermostats in an automatic night set back operation. (QFFR2 or QFFR12) LOW VOLTAGE TRANSFORMER/RELAYS: (Primary or Secondary) Transformer/Relays shall be available as optional equipment to control 208, 240 or 277 volt heaters (with single point supply connection and internal supplied 24 volt control circuit) in conjunction with central energy control systems. The built-in thermostat can then be used as one of the thermostats in an automatic night set back operation. (QFFTR4 OR QFFTR7) SURFACE MOUNTING FRAME: The surface mounting frame, designed to allow full surface mounting, shall be of 14 gauge cold-rolled steel, phosphatized, then electrostatically painted by a powder coat process.(QFFSM) T-BAR FRAME: For T-Bar mounting, a 14 gauge cold-rolled steel frame, phosphatized and electrostatically painted by a powder coat process, shall be available. Frame shall be designed to mount in a standard 2’ x 2’ ceiling grid.(QFFTBF) **Berko reserves the right to change specifications without prior notice.
