The model BD is a low proximity hood with optional rear discharge make-up plenum (BD-BR). Hood shall have size, shape and performance specified on drawings.

Construction shall be type 430 stainless steel with a #3 or #4 polish where exposed. Individual component construction shall be determined by manufacturer and ETL. Construction shall be dependent on the structural application to minimize distortion and other defects. All seams, joints and penetrations of the hood enclosure to its lower outermost perimeter that directs and captures grease-laden vapor and exhaust gases shall have a liquid-tight continuous external weld in accordance with NFPA 96. Hood shall be wall type with a minimum of four connections for hanger rods. Connectors shall have 9/16" holes pre-punched in 1 ½" x 1 ½" angle iron at the factory to allow for hanger rod connection by others.

Ventilator shall be furnished with UL classified aluminum baffle filters, supplied in size and quantity as required by ventilator. The filters shall extend the full length of the hood and the filler panels shall not be more than 6" in width.

The hood manufacturer shall supply complete computer generated submittal drawings including hood sections view(s) and hood plan view(s). These drawings must be available to the engineer, architect and owner for their use in construction, operation and maintenance.

Exhaust duct collar to be 4" high with 1" flange. Duct sizes, CFM and static pressure requirements shall be as shown on drawings. Static pressure requirements shall be precise and accurate; air velocity and volume information shall be accurate within 1-ft increments along the length of the ventilator.

UL incandescent light fixtures and globes shall be installed and pre-wired to a junction box. The light fixtures shall be installed with a maximum of 4’0" spacing on center and allow up to a 100 watt standard light bulb.

• A double wall insulated front to eliminate condensation and increase rigidity. The insulation shall be 1" thick, have a flexural modulus of 475 EI, meet UL 181 requirements and be in accordance with NFPA 90A and 90B.
• An integral baffle to direct grease laden vapors toward the exhaust filter bank.
• A built-in wiring chase shall be provided for outlets and electrical controls on hood face and shall not penetrate capture the area or require an external chaseway.
• The grease drain system shall be an enclosed integral part of the hood back and have slope with an exposed, removable ½ pint grease cup to facilitate cleaning.

The hood shall be ETL Listed as "Exhaust Hood Without Exhaust Damper", ETL Sanitation Listed and built in accordance with NFPA 96. The hood shall be listed for 450° F cooking surfaces at 125 CFM/ft. with High Velocity Cartridge Filters and at 150 CFM/ft. with baffle filters. The hood shall also be listed for 600°F cooking surfaces at 180 CFM/ft. with High Velocity Cartridge Filters and at 200 CFM/ft. with baffle filters.

Optional back supply plenum shall provide make-up air discharged below the cooking equipment. All seams shall be welded and have stainless steel on exposed surfaces. Perforated diffuser plates shall be included in the design, to provide even air distribution. Unexposed surfaces shall be constructed of aluminized steel. Plenum shall be insulated to prevent condensation.
