Gaylord CG3-UV-BDL-DS Specifications

Ultima VentTM with UV Technology

MODEL “CG3-UV-BDL-DS”

WATER-WASH VENTILATOR WITH UV

GENERAL SPECIFICATIONS

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

GENERAL: Each ventilator shall have one high-velocity centrifugal grease
extractor with two air inlet slots, one on each side of the extractor. One slot
shall have an adjustable baffle to regulate the ratio of exhaust volume
between the two slots. Each ventilator 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 grease
particulate. It shall also include a particulate separator and ultraviolet lamps
to remove a majority of the remaining particulate for a total grease extraction
efficiency of up to 99% when operated and maintained in accordance with
the Gaylord Technical Manual and design specifications. The baffle at the
air inlet shall be a three position damper controlled by an electrically driven
actuator, specifically listed for such use. 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 the wash cycle.
The ventilator shall include A "Super Capture"
enhancement of smoke and grease capture. Continuous brackets shall be
provided to facilitate 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).

ULTRAVIOLET LIGHT SECTION: The ventilator shall include ultraviolet
lamps mounted in modules located in the plenum section. There shall be
one or more UV modules, as dictated by the ventilator length, and each
module shall be on a slide track for easy removal. There shall also be a
particulate separator located in the plenum area immediately upstream of
the modules. Access to the particulate separator shall be through the
ventilator extraction chamber inspection doors. Access to the UV modules
shall be through keyed hinged doors, and shall include an interlock switch
to shut off the lamps in the event the doors are opened during operation.
A pressure switch shall be provided to monitor the airflow to prevent
operation of the lamps when the airflow is inadequate. The wash inspection
doors shall be equipped with an interlock switch to prevent the operation of
the UV lamps if the doors are open. Mounted on the face of the plenum of each
ventilator section shall be indicator lights to monitor “UV System On”, “UV Lamp
Failure” and “UV Safety Interlock Activated”. A duplicate set of these lights shall
be mounted on the Ventilator Control Cabinet. The control cabinet shall be
equipped with an audible alarm indicating there is a lamp failure or one of the
safety interlock switches has been activated.

AUTOMATIC WASHDOWN SYSTEM: The ventilator shall include two full
length wash manifolds equipped with brass spray nozzles. When the wash
cycle is initiated, the exhaust fan and UV lamps shall shut off, the damper
shall close forward to seal off the air inlet slot exposing the entire grease
gutter to the wash sprays and the wash sprays shall come on for the length
of time programmed in the control. The upper manifold shall wash the UV
lamps, removing the day’s accumulation of oxidized grease particulate, and
shall wash the topside of the particulate separator. The lower manifold shall
wash the grease extractor and the bottom side of the particulate separator.
At the conclusion of the wash cycle the damper shall remain closed, in the
“Wash” 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 fail-safe 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
UV lamps, 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 grease extractor,
UV chamber 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. At the conclusion of the cool down period the water sprays shall shut off.
The damper shall remain closed until the exhaust fan is restarted.

APPLICATION

Used for typical island style cooking arrangements where light or medium
equipment is used on one side and light-duty equipment on the other, and
the distance between the equipment does not exceed 30". Consult factory
for exceptions. Refer to the Master Engineering Data Sheet in the Gaylord
catalog for determining light and medium equipment.

o Fuse Link Activated Fire Damper (optional) (series prefix “CG3-UV­FDD”) The damper shall be activated by fuse link(s) located at the duct collar.

The ventilator shall be UL listed under the category “Exhaust Hood with
Exhaust Damper”.

o Ventilator without Fire Damper (optional) - (series prefix “CG3-UV-ND”)

The ventilator shall be UL listed under the category “Exhaust Hood without
Exhaust Damper”.

ACCESSIBILITY AND INSPECTION: The ventilator shall be equipped with
full-length hinged inspection doors so that service can be performed on the
UV lamps, fire suppression system nozzles, fusible links, wash system
manifolds and nozzles, drains and other interior components.

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 single connection
points. On multiple section ventilators power for the UV lamps must be sup­plied to each section. Wiring for controls and light fixtures shall be furnished
with coiled flex conduit for interconnecting sections by applicable trades.

LIGHT FIXTURES: The ventilator shall be equipped with o 100 watt surface
mounted incandescent, o 150 watt recessed incandescent,
o recessed fluorescent, light fixtures. Light fixtures shall be factory pre-wired
to a single connnection point. Ventilators built in multiple sections shall be
furnished with coiled flex conduit for interconnecting sections.

ACCEPTANCE & APPROVALS: The ventilator shall be UL and NSF listed.
The ventilator shall comply with all requirements of NFPA-96, IMC, UMC,
BOCA and SBCCI model codes.

ENGINEERING DATA

Exhaust volume depends upon the type of cooking equipment and the type and
volume of cooking. Refer to the Master Engineering Data Sheet in the Engineering
Data section of the Gaylord catalog for the charts to determine exhaust and supply
volume, S.P., duct, hot water, and drain sizes. The standard CG3-BDL-DS ventilator
operates at 250 CFM/lin. ft. on the medium side and 150 CFM/lin. ft. on the light side
for a total of 400 CFM/Lin. ft. If the cooking equipment requires more exhaust, as
determined by the Master Engineering Data Sheet, it may be necessary to use back­to-back ventilator model CG3-BDL-BB series (consult factory).
