Turning On the Exhaust Fan

Caution: Always turn on the exhaust fan before turning on the cooking equipment.

Caution: The chemical fire extinguishing system may discharge if the exhaust fan is not on while the
cooking equipment is on or still hot.

Caution: Never operate your Ventilator without the Grease Filters in place. Refer to Figure 2-1-1.

To operate the exhaust fan flip the fan switch to the ON position. The switch is typically mounted on a wall
near the Ventilator or it may be mounted on the face of the Ventilator.
Note 1: The EL Series Ventilator may be equipped with a Gaylord Electric Balancing Damper, designated
“GEBD” in the Ventilator model number. The Ventilator model number can be found on the Ventilator
Nameplate (Refer to Figure 4-4-1 for a sample of the nameplate and to Page 4-7 for information on
Balancing Dampers). If the Ventilator includes this damper, when the fan is started the damper moves
from the closed to open position and it will take approximately 45 seconds for the exhaust to come up to
100%.
Note 2: Typically EL Series Ventilators installed in the United States are equipped with a Gaylord Autostart
Controller Model AS or DCA that automatically turns on the exhaust fan if the temperature at the sensors
mounted in the canopy exceeds 90°F. (Refer to Figure 2-2-1). In some instances Ventilators installed
outside the United States will include an Autostart Control. Inclusion of an Autostart Control is designated
by the suffix AS or DCA in the model number. The Ventilator model number can be found on the
Ventilator Nameplate (Refer page 4-4-1 for a sample of the Nameplate). Refer to the Operation,
Maintenance and Installation Manual for the Gaylord Command Center for complete information on the
Autostart Control.
Note 3: If Gaylord model ELX-UVi or ELXC Series Ventilators are connected to the same exhaust fan as an

EL Series, then the exhaust fan would be controlled by a Gaylord Command Center. The manual for the

Command Center is titled Operation, Maintenance and Installation Manual for the Gaylord Command
Center and Wash Control Cabinet. Refer to this manual for instructions for turning on and off the exhaust
fan.

Turning Off the Exhaust Fan

Caution: Always turn off the cooking equipment and allow cooling before turning off the exhaust fan.
The chemical fire extinguishing system may discharge if the cooking equipment is on or hot when the
exhaust fan is off.

At the end of the cooking day, turn off the cooking equipment and allow cooling before turning off the
exhaust fan. To turn off the exhaust fan flip the fan switch to the OFF position
Note 1: If the Ventilator includes a Gaylord Autostart Controller the exhaust fan will stay on if the
temperature at the duct collar is above 90°F. Once the temperature drops below 90°F., the fan will
continue to run for 20 to 60 minutes and then shut off.
Note 2: If the Ventilator is equipped with a Gaylord Electric Balancing Damper, designated GEBD, when
the fan is turned off the damper will move from the open to the closed position, and remain closed until
the exhaust fan is re-started. Closing the damper saves building energy by not allowing conditioned air
from drafting up the exhaust duct, or in cold climates prevents cold air from coming down the duct and
into the kitchen.

Grease Extraction

Grease is extracted by either Listed Grease Filters or by the use of Gaylord Model XGS Extractors. Grease
is removed from the exhaust air by centrifugal force as it passes through the filter. The hot grease laden
contaminated air rising from the cooking surface is drawn through the filters where a percentage of the
grease and other particulate are extracted from the airstream. The extracted liquid grease will drain down
the filters and into the Grease Gutter which then drains to the Grease Drawer. The sticky grease will
remain in the filters until cleaned.

The optional Gaylord Model XGS Extractor provides significantly higher grease extraction efficiency than
the Listed Grease Filters. The Extractors are ETL Recognized as part of the EL Ventilator. They are
constructed of corrosion resistant stainless steel.

Maintenance and Cleaning Instructions

Overview

To maintain the Gaylord Ventilator in good working order, and to keep the system operating at optimum
efficiency, preventive maintenance using the following schedule should be performed.

Daily Cleaning and Maintenance

At the end of the each cooking day, or at periodic intervals, depending upon the type of cooking, the filters
or XGS Extractors must be removed and cleaned. Caution: Before removing the filters/Extractors check to
see that the exhaust fan is shut off and the cooking equipment is cool. To remove the filters/Extractors
and clean proceed as follows:

1. Remove filters/Extractors: Caution: Care should be taken when removing the filters/Extractors,

especially over fryers. It is recommended that the cooking equipment be cooled down and the fryers
be covered prior to removing. They may be removed by hand or by use of an optional Filter/Extractor
Removal Tool (Refer to Figure 2-3-2). To remove, lift up slightly on the Filter/Extractor and pull out
from the bottom, then straight down.

2. The Filter/Extractor may be cleaned either by using a dishwasher or by soaking in a deep well sink using

hot water with a degreasing detergent, scrubbed and rinsed. Gaylord Formula G-510EF detergent is
highly recommended for this application. Refer to Page 2-5 for details.

3. With the filters/Extractors removed inspect the back wall and the underside of the exhaust plenum. If

necessary clean with hot detergent water.

4. Wipe and clean the Grease Gutter.

5. Remove and empty the Grease Drawer and replace.

6. Replace the filters or Extractors. Important Note: Filters and Extractors must be installed with the

openings running vertical as shown in Figure 2-3-1. Gaylord XGS Extractors have an arrow stamped on
the face designating “UP”.

7. Wipe the interior surfaces of the hood as required.
