Suggested Engineering Specifications:

Model SB Architectural Draft Barriers shall be 5″ high and 3″ wide. The front cover shall be 14 gauge extruded aluminum construction suitable for Architectural, Commercial and Industrial use with 1/4″ pencil proof intake and discharge grills. The one piece cover shall be extruded for maximum strength and shall be available in lengths up to 12′.

The cover shall be linear mount to the 14 gauge heater back with no visible fasteners. The 14 gauge heater back shall be suitable for mullion to mullion mounting.

Standard painted finishes or optional anodizing (see color chart) shall be provided as specified by the architect. Color matching to architects specifications are available as optional finishes.

Heat sections from 2′ to 10′ are available. All heaters shall contain 3/4″ EMT built in raceway with factory wiring to provide field wiring from either end when optional controls are not included.

1/2″ and 3/4″ knockouts shall be provided in the side and rear of the heater junction box to permit end to end wiring. All blank sections shall be fully enclosed to allow branch circuit wiring. All heaters shall contain a full length thermal overheat protector with automatic reset. Wattages shall be available from 100 to 250 watts per foot. Heating elements shall be tubular stainless steel or aluminum tubing with aluminum fins mechanically bonded to ensure efficient heat transfer.

Element fin temperature shall not exceed 350 degrees Fahrenheit to ensure long element life. Elements shall be center anchored and free floating in nylon bushings at each end.

Control sections include 6″ or 12″ with: disconnect, thermostat, pneumatic relay, transformer relay, relay, fused disconnect or duplex receptacle. Standard built-in controls shall include thermostats (single and double pole) and disconnect switches.

Built-in controls shall be tamper proof and shall be adjustable with a blade screwdriver through the discharge louver.

All heaters are Underwriters Laboratories listed.

SB-PD

SB-PD series shall have 2″ adjustable pedestals and the heater back will be painted to match the front cover.

Standard Painted Finishes:

Black, Bronze, Grey, Tan, White, Prime Grey

Available Anodized Finishes

204, 311, 312, 313 and 315.

Furniture, Drapes & Carpeting

Proper operation of heater requires free circulation of room air through the heating element. Keep electrical cords, drapes, rugs and other furnishings away from the heater. Furniture should be placed no closer than 4″ from the heater.

Drapes should clear the top of the heater by at least 12″. Or, if you prefer floor length drapes, they should clear the floor by 3″, and the minimum clearance from the back fold to the front cover should be at least 4″.

For best results when carpeting is involved in the installation, allow clearance for carpet to be installed under the heaters and corners. Rugs can be placed up to the heater provided that they are not of a thickness that would block the air-intake at the bottom of the heater.
