Gaylord CG3-BDL-BB-MA Specifications

MODEL “CG3-BDL-BB-MA”

WATER-WASH VENTILATOR

Furnish Gaylord Ventilator Model “CG3-BDL-BB-MA___” as shown on plans
and in accordance with the following specifications:

GENERAL: Ventilator shall incorporate two extraction chambers mounted
back-to-back each with an air inlet opening above and parallel to the cooking
surface. Each extraction chamber shall utilize three full-length horizontal self
draining baffles for centrifugal grease extraction providing a grease extraction
rate of up to 95% of the mechanically extractable particulate when operated
at design specifications. The use of filters, cartridges or constant running water
to extract grease is not acceptable. The baffle at the air inlet shall be a three
position damper controlled by an electrically driven actuator. In position
number one, the fan on mode, the damper shall be a grease extracting baffle,
position two the damper shall be in the wash mode and position number three
in the fire mode. The main grease gutter shall have a 1" slope to the drain
opening and the drain shall be equipped with a pre-flush line to purge the drain
during a wash cycle. Continuous brackets shall be provided to facilitate to the
wall and hanging from the overhead structure. ❏ (Optional) The ventilator shall
include “Custom Air” baffles to reduce the exhaust air volume over specific
cooking equipment as indicated on the plans (add suffix “CA” to model number).
The ventilator shall operate at air quantities as shown on plans.

AUTOMATIC WASHDOWN SYSTEM: The ventilator shall include a full-length
wash manifold equipped with two rows of brass spray nozzles. When the wash
cycle is initiated the exhaust fan is shut off, the damper shall close forward to
seal off the air inlet slot exposing the entire grease gutter to the wash sprays.
At the conclusion of the wash cycle the damper shall remain closed, in the
“System Off” position, preventing conditioned air from escaping the occupied
space via thermal drafts, and then re-open when the exhaust fan is started.
All controls and components for operation of the wash system shall be housed
in the Ventilator Control Cabinet.

INTERNAL FIRE PROTECTION: The ventilator shall be equipped with an
internal fire protection system activated by thermostat(s) located at the duct
collar. When the temperature of the exhaust air reaches the set point, the fire
damper shall automatically close in the direction of the exhaust air flow, sealing
against the back wall of the ventilator, and act as a barrier to prevent flame
from entering the extraction chamber and duct system. The exhaust and make
up air fans shall shut off, and the internal wash system shall be initiated, acting
as a deterrent to fire in the plenum and exhaust ductwork. In addition, the
internal water sprays shall continuously bathe the fire damper to eliminate
warping of the damper during a severe fire condition. The water sprays shall
remain on until the thermostat temperature drops below its set point, then stay
on for a two minute cool down cycle. During the cool down cycle the damper
shall open and upon completion the water sprays shall shut off and the exhaust
fan re-start. o(Optional) A remote fire switch shall be provided and shall be
located at an exit. Pulling the fire switch shall turn on the water sprays, open
the fire damper to the fan on position and turn on the exhaust fan.

MAKE-UP AIR OPTIONS: The ventilator shall have an air supply plenum, with
duct collar(s) and:
o Incorporate registers for front face discharge make-up air. (Add suffix “MAR“
to the model number.)
o Incorporate removable stainless steel perforated panels for front face
discharge make-up air. (Add suffix “MAW” to the model number.)

o (Optional Fuse Link Fire Dampers) Provide fuse link activated fire damper
located at the duct collar. Specifier note: This arrangement eliminates the three

position inlet damper and is replaced by a fixed baffle. This option is identified
by the model number prefix CG3-FDD.

o (Optional No Fire Damper) This option is identified by the model number prefix
CG3-ND.

ACCESSIBILITY AND INSPECTION: The ventilator shall be equipped with full­length non-gasketed hinged inspection doors so that service can be performed
on fire suppression system nozzles, fusible links, wash system manifolds and
nozzles, drains and other interior components without removing any panels,
dampers or baffles. No tools shall be required to access the interior of the
extraction chamber or plenum.

CONSTRUCTION: The ventilator shall be of all stainless steel construction, not

less than 18 gauge, type 300 series. All exposed surfaces shall be a number
4 finish. The use of aluminized steel, galvanized steel, or 430 stainless steel
is not acceptable.

ELECTRICAL: The ventilator shall be factory pre-wired to a single connection
point. Ventilators built in multiple sections shall be furnished with coiled flex
conduit for interconnecting sections by applicable trades.

LIGHT FIXTURES: The ventilator shall be equipped with ❏100 watt surface
mounted incandescent, ❏ 150 watt recessed incandescent, ❏ recessed
fluorescent, light fixtures. Light fixtures shall be factory interwired. Ventilators
built in multiple sections shall be furnished with coiled flex conduit for
interconnecting sections.

ACCEPTANCE & APPROVALS: The ventilator shall be UL Listed under the
category “Exhaust Hood with Exhaust Damper” and listed by NSF. The
ventilator shall comply with all requirements of NFPA-96, IMC, UMC, BOCA and
SBCCI model codes. In Canada the ventilator shall be ULC Listed and CSA
Certified.

APPLICATION

Used for typical island style cooking arrangements where medium,
heavy, and extra heavy-duty cooking equipment is used on both sides
or when the distance between the equipment exceeds 30" regardless
of the type of equipment. Refer to the Master Engineering Data Sheet
in the Engineering Section of the Gaylord catalog for determining
medium, heavy, and extra heavy-duty equipment. Includes built-in
make-up front face air discharge.

FEATURES

• Three Position, Inlet Slot, Damper

• 95% Grease Extraction Efficiency

• CUL and NSF Listed

• Complies With The IMC, UMC, BOCA and
SBCCI Mechanical Codes

• Complies with all Requirements of NFPA-96

• Fail Safe Damper Control Switch

DESCRIPTION

The Gaylord Model “CG3” Series Ventilator has been tested to UL
Standard 710 and is UL Listed under the category “Exhaust Hood with
Exhaust Damper”. The ventilator extracts up to 95% of the mechanically

extractable grease by centrifugal force when operated and maintained

in accordance with design specifications. The extracted grease remains
out of the airstream until washed away by the hot water, detergent injected
wash cycle, which is manually activated by pushing the “Start Wash” button
on the control cabinet or automatically activated by the control cabinet if
equipped with optional time clock. The 24 hour fire protection is
accomplished by the action of the thermostat(s) located at the duct collar.
Whenever temperatures reach the set point, the fire cycle is activated
which closes the damper at the air inlet of the ventilator, releases fire
extinguishing water spray into the interior of the ventilator, and shuts off
the exhaust and supply fan.

OPTIONAL EQUIPMENT

1. Decorative Facings and Trim

2. Exhaust Fans, Supply Fans, & Roof Top Units

3. Fire Extinguishing Systems

4. Custom Air (low air volume ventilators)

5. Continuous Cold Water Mist

6. Utility Distribution Systems

7. Pollution Control Systems
