Ultima VentTM with UV Technology
MODEL “CG3-UV-BDL-MA”
WATER-WASH VENTILATOR WITH UV
GENERAL SPECIFICATIONS
Furnish Gaylord Ventilator Model “CG3-UV-BDL-____” as shown on plans
and in accordance with the following specifications:
GENERAL: Each ventilator shall be a high velocity type grease extractor
with an air inlet opening above and parallel to the cooking surface. 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"TM lip on the front panel for
enhancement of smoke and grease capture. The ventilator shall include
a built-in 3" air space at the rear for compliance to NFPA-96 when mounting
against a limited combustible wall. Continuous front and rear brackets shall
be provided to facilitate mounting 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).
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 door 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 indicating 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.
ITEM NO. _______________
APPLICATION
For use over all types of equipment; ovens, broilers, griddles, fryers,
ranges, steam equipment, and where integral front face discharge
make-up air is desired. Cannot be used over solid fuel cooking
equipment.
MAKE-UP AIR OPTIONS: The ventilator shall have an air supply plenum, with
duct collar(s) and:
❏ Incorporate registers for front face discharge make-up air. (Add suffix “MAR”
to the model number.)
❏ Incorporate removable stainless steel perforated panels for front face
discharge make-up air. (Add suffix “MAW” to the model number.)
❏ 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”.
❏ Ventilator without Fire Damper (optional) - (series prefix “CG3-UVND”) 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 ❏ 100 watt surface
mounted incandescent, ❏ 150 watt recessed incandescent,
❏ recessed fluorescent, light fixtures. Light fixtures shall be factory prewired 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.
