TABLE OF CONTENTS

OPERATION

FAN OPERATIONTo operate the exhaust fan turn on the fan switch that is typi-cally mounted on a wall near the hood. The “XG” hood may be equipped with a fan, auto start controller, and/or light switch mounted on the face of the hood.

GREASE EXTRACTION (XG EXTRACTORS)The Gaylord Industries Patent Pending XG Extractor Cartridge is designed to deliver the absolute optimum in collection effi-ciency at the lowest possible pressure drop. The units are ETL listed to UL 1046 standard, and are also recognized as part of an XG Ventilator. They are constructed of corrosion resistant stainless steel and feature a GX style handle for easy removal from the ventilator to which they are mounted. Another great feature of the XG filter is that it can be opened up and turned back on itself for easy and efficient dishwasher cleaning. The opening of the filter is accomplished by a top mounted, dual hinge and a set of snap buttons at the bottom to secure the filter in position. The benefit to such a design ensures that restaurant employee’s will always have access to the inside of the extractors for easy cleaning, and will not mistakenly install the units in the opened, or disassemble position.

CLEANINGAt the end of the cooking day, or at periodic intervals, cartridges are removed and washed either in a dishwasher or soaked in a deep well sink, scrubbed and rinsed.

FIRE PROTECTIONNFPA #96 requires the use of surface, duct and plenum pro-tection on all hoods.

These systems are designed to detect and extinguish fires on the cooking surface, within the plenum and at the duct collar. Refer to the fire extinguishing system owner’s manual for opera-tion and maintenance instructions of these systems.

The “XG-GFBD” hood is equipped with an exhaust duct fire damper. In the event of a fire, should the thermostat reach its activation point of 325° F, the damper would close preventing the flames from entering the ductwork and spreading to other parts of the building. The fire is contained in the kitchen area where it can be properly fought.

The hood may be supplied without a fire damper which is designated by the suffix “ND” in the model number or with a Balancing Only damper denoted with a “GBD” in the model number. Refer to the nameplate on the hood for the exact model number. (See Figure 7, page 5).

MAINTENANCE AND CLEANING INSTRUCTIONS

At the end of each cooking day, the exposed interior surfaces of the hood should be wiped down and the grease cup emptied. During the course of operation, grease particles are gradually collecting inside the cartridge extractors. Daily, or at periodic intervals, depending on the type of cook-ing, the cartridge extractors must be removed and cleaned. To clean, proceed as follows:

1. Remove filters. CAUTION: Care should be taken when removing filters, especially over fryers. It is recommended that the cooking equipment be cooled down and the fryers be covered prior to removing filters. To remove, lift up slightly on filters and pull out at the bottom, then straight down.

2. Filters may be cleaned either by using a dishwasher or by soaking in deep well sink using hot water with a degreasing detergent, scrubbed and rinsed. Prior to cleaning, open the XG extractor to gain access to the filters interior. Formula G-510 is highly recommended for this application. For information contact:

3. With extractors removed, wipe and clean the back wall and top of the plenum area and the grease gutter with hot detergent water. NOTE: If steam or hot water pressure wash is used for periodic cleaning of the interior, remove the grease drawer and connect a hose to the gutter drain and lead it to a floor sink or large bucket to drain off water.

4. Replace extractors. Be sure to replace extractors with baffles running vertical as shown in Fig. 5.

IMPORTANT NOTE: In the event of a fire the thermostat must be replaced. (Applicable to GFBD models only.)

CAUTION: Care should be taken when removing extractors, especially over fryers. It is recommend-ed that the cooking equipment be cooled down and the fryers be covered prior to removing filters.

INSPECTION AND CLEANING REQUIREMENTSThe 1998 edition of NFPA-96 (Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations) require that hoods, ducts and exhaust fans be inspected by a properly trained, qualified and certified company or person(s) in accordance with the following table.

Upon inspection, if found to be contaminated with deposits from grease-laden vapors, the entire exhaust system shall be cleaned by a properly trained, qualified, and certified company or person(s) acceptable to the authority having jurisdiction in accordance.

When a vent cleaning service is used, a certificate showing date of in-spection or cleaning shall be maintained on the premises. After cleaning is completed, the vent cleaning contractor shall place or display within the kitchen area a label indicating the date cleaned and the name of the servicing company. It shall also indicate areas not cleaned.

Factory trained service agencies are cer tif ied by Gaylord Industries to perform these inspections. For the name and phone number of your nearest agent, call 1-800-547-9696 or send an e-mail to info@gaylordusa.com.

2. Verify damper motor proper operation and that it is getting its requirement of power.

MEASURING AIRFLOW

Measuring Airflow The XG hood has been designed to give you an approximate airflow per linear foot of hood based on the static pressure measured at a particular location on you XG hood section. The method will require the balancer to have a manometer, (Dwyer 475-00 FM recommended), which he/she will use to get a static pressure measurement for every hood section. The static tap, as seen in fig. 8, will be located behind a small 4 to 6 screw access cover, located directly above your filters.

Instructions:

1. Turn on the exhaust fan to the hood section you intend to measure the exhaust airflow.

2. Remove access cover as seen in fig. 8. 3. Locate the static tap, and remove the

sealing boot. 4. Zero you Dwyer 475-00 Digital

Manometer. 5. Take the 1/8” vinyl tube attached to your

Dwyer 475-00 Digital Manometer and attach it to the static tap.

6. Record the value indicated on your meter.

7. Compare your recorded values to Fig. 9, Airflow vs. Static Tap Chart to determine your rate of flow for the hood per unit length of the hood. Total flow will be the CFM/LFobtained from Fig. 9 multiplied by thelength of the ventilator section.

8. Design values will be noted on the listing label attached to the inside of the ventilator, or sticker attached to the inside of the access cover.

Fig. 9, Airflow vs. Static Tap Chart

Balancing Hood system flow rates are to be adjusted to obtain the correct pressures noted above. Flow adjustment for the XG ventilator is to be done by either manipulation of the Gaylord Industries GBD, or GFBD balancing dampers, or by fan pulley adjustment. Reference your GBD/GFBD technical manual for more details Consult the Gaylord Industries factory for Listed, and recommended airflow rates over particular equipment line up, as well as best practice system balancing, and equipment place.
