Gaylord GX2-BDL-DS-CL Specifications

MODEL “GX2-BDL-DS-CL”

NON WATER-WASH VENTILATOR

GENERAL SPECIFICATIONS

Furnish Gaylord Ventilator Model “GX2-BDL-DS-CL-____________” 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 contain one or more removable
“extractor inserts” with a grease extraction efficiency of 90% when operated
at design specifications. Extractor inserts shall be constructed of stainless
steel and contain full-length, self-draining baffles. Extractors shall be easily
removable, for periodic cleaning, from the floor area immediately in front of
the equipment by utilizing an extractor removal tool. The grease collecting
gutter at the bottom of the extractor housing shall slope to a drain at one end
of the ventilator to a removable stainless steel grease cup. The sloped gutter
shall be concealed by an apron which extends the full length of the hood.
Continuous brackets shall be provided to facilitate hanging from the
overhead structure.
baffles to reduce the exhaust volume over specific cooking equipment as
indicated on the plans (add suffix “CA” to model number). The ventilator shall
operate at air quantities and static pressure as indicated on plans.

❏ ❏

❏ Ventilator with a Fire Damper (standard equipment) - The ventilator

❏ ❏

shall be equipped with a full length fire damper located in the ventilator
extractor plenum between the extractor inserts and the ventilator duct collar.

❏ ❏

❏ Thermostatically Operated Fire Damper (standard) - The damper

❏ ❏

shall be controlled by an electrically driven actuator, specifically listed for
such use and shall be activated by fail safe thermostat(s) located at the duct
collar. Upon activation, the exhaust and supply fan shall shut off and the
damper shall close, in the direction of air flow, sealing against the front of the
plenum and act as a fire barrier to prevent flame from entering the plenum
and duct system. The damper shall also close each time the exhaust fan
is turned off, to prevent conditioned air from escaping the occupied space
via thermal drafts, and then re-open when the exhaust fan is started. Fire
dampers located at the exhaust duct collar are not acceptable. The ventilator
shall be UL listed under the category “Exhaust Hood with Exhaust Damper”.
Access doors to reach duct fire protection nozzles shall not be permitted.

❏ ❏

❏ Fuse Link Activated Fire Damper (optional) - (series prefix “GX2-

❏ ❏

FLD”) The damper shall be spring loaded and activated by fuse link(s)
located at the duct collar. Upon activation, the exhaust and supply fan shall
shut off and the damper shall close, in the direction of air flow, sealing against
the front of the plenum and act as a fire barrier to prevent flame from entering
the plenum and duct system. The damper shall be manually reset without
the use of tools and without opening or removing access panels. Dampers
located at the exhaust duct collar are not acceptable. The ventilator shall
be UL listed under the category “Exhaust Hood with Exhaust Damper”.

❏ ❏

❏ Ventilator without Fire Damper (optional) - (series prefix “GX2-ND”)

❏ ❏

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

CONSTRUCTION: The ventilator shall be of all stainless steel construction,
not less than 18 gauge, type 304. All exposed surfaces shall be a number
4 finish. The use of aluminized steel, galvanized steel, or 430 stainless steel
is not acceptable in any part of the ventilator.

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 prewired to a single
connection 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.

❏❏

❏ (Optional) The ventilator shall include “Custom Air”

DESCRIPTION

The Gaylord Model “GX2” 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 90% of the grease
by centrifugal force when operated and maintained in accordance with
design specifications. Centrifugal grease extraction is accomplished
by unique, removable stainless steel “extractor inserts” that incorpo­rate a series of horizontal baffles. At the end of the cooking day or at
periodic intervals, the inserts are removed and can be washed either
in a dishwasher or soaked and rinsed off. An extractor removal tool
is available which makes removal of the extractors extremely easy.
The extractor inserts come in two sizes: 15½" (5¼ lbs.) and 19½
(6¾ lbs.). The GX2 series is equipped with a thermostatically activated,
or optional fuse link activated, internally mounted fire damper. The
ventilator is also available without a fire damper, identified by the prefix
“GX2-ND”. The GX2 series can be totally integrated with the “CG3”
water-wash series.

Mechanical Requirements

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 “GX2-BDL-DS-CL” ventilator operates
at 250 CFM/lin. ft. on the heavy 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 back-to-back
ventilator model “GX2-BDL-BB” series (consult factory).

Electrical

A Gaylord stop/start switch, Model C-250, is provided for each exhaust fan. Refer
to Model C-250 specification sheet in the Control Cabinet section of the Engineering
Catalog for specifications and electrical details. Lights to be on separate circuit, 120
volt standard, 220/240 volt optional.
