ADDITIONAL COPIES $7.00 OPERATION FAN OPERATION To operate the exhaust fan turn on the fan switch that is typically mounted on a wall near the hood. The “PG” hood may be equipped with a fan and/or light switch mounted on the face of the hood. GREASE EXTRACTION The Gaylord “PG” Series Hood, as a standard, utilizes UL Classified filters to extract the grease from the airstream. The filter is a self-balancing baffle type and is constructed of aluminum or stainless steel. Typical grease extraction rate varies between 40% and 65%. The hood may be equipped with optional extractor cartridges, as shown in figure 6 page 3, that have a grease extraction efficiency of up to 90%. When equipped with cartridges, the model number prefix is “PGX”. Refer to the nameplate on the hood for exact model number. (See Figure 7, page 5.) CLEANING At the end of the cooking day, or at periodic intervals, the filters or cartridges are removed and washed either in a dishwasher or soaked in a deep well sink, scrubbed and rinsed. GREASE EXTRACTION FIRE PROTECTION NFPA #96 requires the use of surface, duct and plenum protection 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 operation and maintenance instructions of these systems. The “PG” hood is equipped with an exhaust duct fire damper. In the event of a fire, should the fuse link reach its activation point of 212 °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. Example: “PG-ND”. Refer to the nameplate on the hood for the exact model number. (See Figure 7, page 5).

FIGURE 2 Standard Ventilator Models STANDARD MAKE-UP AIR OPTIONS The make-up air options shown below are available on all BDL Series Ventilators. MODEL “MAW” SERIES FIGURE 3 FRONT FACE DISCHARGE Standard Make-up Air Options This method of introducing make-up air into the kitchen is flexible and has many advantages. Make-up air is discharged through stainless steel perforated panels as illustrated (MAW Series) or optional registers. Typical supply volume is 80% of the exhaust or more, depending on air balance desired. Supply air temperatures should range from 60 to 65°F (16 to 18°C), but may be as low as 50°F (10°C) depending on air volume, distribution, and internal heat load. 2 MODEL “MAI” SERIES INTERNAL DISCHARGE This method of introducing air into the hood is typically referred to as the “short circuit” method. This design has very limited applications and the amount of supply air able to be introduced varies considerably with the type of cooking equipment. This air may be untempered air in most areas depending upon climatic conditions and the type of cooking equipment. The difference between the quantity of air being introduced and the amount of air being exhausted must be supplied through a traditional make-up air system. 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 filters or optional cartridge extractors. Daily, or at periodic intervals, depending on the type of cooking, the filters or 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. Formula G-510 is highly recommended for this application. For information contact: FIGURE 4 NOTE: NEVER OPERATE THE HOOD IF THE FILTERS ARE NOT IN PLACE. 20/10 Products P.O. Box 7609 Salem, Oregon 97303 Phone: 800-286-2010 Fax: 503-363-4296 email: email@example.com 3. With filters removed, wipe and clean the back wall and top of the plenum area and the grease gutter with hot detergent water. NOTE: If a steam or hot water pressure is used for periodic cleaning of the interior, remove the grease cup and connect a hose to the gutter drain and lead it to a floor sink or large bucket to drain off water. 4. Replace filters. Be sure to replace filters with baffles running vertical as shown in Fig. 5., or if cartridge extractors are used, the inlet slot is at the top as shown in Figure 6. If the hood is equipped with either an exhaust or supply fire damper, which is located at the duct collar, NFPA #96 requires that the fuse link be inspected semi-annually and replaced annually. It is recommended that a professional service organization be contracted to perform this service. Normally, this could be the same company that services the fire protection system. IMPORTANT NOTE: All exhaust fire damper replacement fuse links must be UL Listed and rated for 212°F (100°C) and all supply fire damper replacement fuse links must be UL Listed and rated for 165°F (74°C). FIGURE 5 NOTE: FILTERS MUST BE INSTALLED WITH BAFFLES RUNNING VERTICAL AS SHOWN. INSPECTION AND CLEANING REQUIREMENTS 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. The 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 inspection 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.

TROUBLE-SHOOTING SYMPTOM SMOKE LOSS 1. Smoke Loss- Hood is not exhausting properly. POSSIBLE PROBLEM CORRECTIVE ACTION A. L o w a i r v e l o c i t y - Av e r a g e a i r v e l o c i t y through the filters or air entr y slot of the car tr idge extractors should be in accordance with the Air Velocity Char ts on page 6 or 7. For proper method of measuring the air velocity, refer to page 6 o r 7 . I f t h e ve l o c i t y i s l ow c h e ck t h e following. 1. Broken or slipping belt on the exhaust fan. 2. Proper rotation of the exhaust fan wheel. 3. P r o p e r s i z e o f e x h a u s t f a n ( f a n m u s t deliver nameplate rating). 4. Ductwork inspection panel left open. 5. E x h a u s t d u c t f i r e d a m p e r n o t o p e n o r i n proper position. B. T h e h o o d m u s t h a v e i t s o w n e x h a u s t s y s t e m a n d n o o t h e r ex h a u s t , s u c h a s dishwasher hoods, should be tied into it. 1. Inspect duct system and verify that there are no other non hood systems tied in. If so they must be removed. C. Improperly placed make-up air diffusers. 1. Make-up air directed at the hood will likely create cross drafts disrupting the air flow into the hood. Adjust the louvers to direct the make-up air away from the hood. 2. Make-up air should be delivered through registers at ceiling height, and distributed throughout the kitchen area. 3. M a k e - u p a i r r e g i s t e r s l o c a t e d n e a r t h e hood, the louvers should be adjusted to direct the air away from the hood. D i r e c t i n g o r fo r c i n g m a k e - u p a i r a t t h e hood typically creates cross drafts resulting in smoke loss. D. Inadequate make-up air. 1. Make-up air must be supplied for replacement of air exhausted through all kitchen exhaust systems. A general "rule of thumb" is that 75% to 80% of the replacement air should be fresh, conditioned, (heated or cooled) air brought into the kitchen area, with the remaining 20% to 25% allowed to flow into the kitchen from adjacent areas. E. Exhaust fan discharge. 1. T h e r e s h o u l d b e n o s c r e e n ove r t h e d i s c h a r g e . I f o n e i s fo u n d , i t s h o u l d b e removed. 2. The direction of discharge should not be into the prevailing winds nor downward onto the roof. A ver tical discharge is highly recommended. GREASE EXTRACTION 1. Poor Grease Extraction. A. H o o d s w i t h b a f f l e f i l t e r s h ave a t y p i c a l grease extraction efficiency of up to 70% and with car tridge extractors an efficiency of up to 90%, when operated and maintained in accordance with design specifications. If it appears that the hood i s n o t ex t r a c t i n g p r o p e r l y, t y p i c a l l y t h e exhaust volume is low. 4 1. Check the inlet slot velocity as described on page 7. If the velocity is not within the required range, increase or reduce the fan speed as required. TROUBLE-SHOOTING SYMPTOM EXHAUST FAN POSSIBLE PROBLEM 1. If when the fan switch is turned on to the ex h a u s t p o s t i o n b u t t h e ex h a u s t fa n does not come on. 2. If when the fan switch is turned on to the exhaust position, air is not being pulled through the hood but you can hear the fan running. CORRECTIVE ACTION A. O ve r l o a d p r o t e c t o r o n t h e m a g n e t i c star ter tripped. 1. P u s h t h e " R e s e t " b u t t o n o n t h e m a g n e t i c s t a r t e r a n d t u r n t h e fa n switch to the "On" position. B. If an HOA (Hand Off/Automatic) type m a g n e t i c s t a r t e r sw i t c h i s u s e d , t h e selector switch may have been moved from the automatic position. Check switch and turn selector to the automatic position. C. Exhaust fan circuit breaker tripped. Re-set circuit breaker. D. If the system is equipped with a fused disconnect switch for the exhaust fan, a fuse or fuses may have blown out. Check continuity of fuses and replace if necessar y. E. Fan on/off switch has not been wired properly. R e fe r t o w i r i n g d i a gra m i n t h i s manual and re-wire. A. Fire damper at exhaust duct collar, if equipped, has closed. 1. Open necessar y access panels to d u c t c o l l a r, i n s p e c t a n d t a ke corrective action.

REFER TO THE GAYLORD VENTILATOR TECHNICAL MANUAL FOR DETAILS. 5 FIGURE 7 UL Nameplate The total required exhaust volume can be found stamped on the UL nameplate located on each hood section MEASURING BAFFLE FILTER VELOCITY MEASURING FILTER VELOCITY Smoke capture and grease extraction efficiency are dependent upon the proper air velocity at the filter. The designed air volume for the “PG” Series hood varies between 150 and 500 CFM per lineal ft. depending upon the type of cooking equipment, and style of hood. Refer to the “Filter Velocity Charts” below. Filter sizes are determined by the designed CFM per lineal ft. The average velocity (FPM) taken at the face of the filter should be within the range shown on the charts. If the velocity is below or above the required average, the exhaust fan should be adjusted accordingly.

The standard instrument used for measuring the filter velocities on a Gaylord Hood is a Pacer, Model DA40 or DA4000 Digital Anemometer. This instrument is the easiest, most accurate and the best suited for measuring filter inlet velocities. To take accurate air velocity readings, follow the instructions below. Instructions 1. Attach the cable from the sensing head to the meter and the handle sections to the sensing head. 2. Place the sensing head against the filter as illustrated in figures 8 and 9. 3. Using the 16 second averaging feature on the meter, slide the head across one or two filters, as illustrated in figure 8, until the 16 second average has elapsed. 4. Record the velocity (fpm) on the start up inspection report form. A sample report form, which can be photocopied, is provided on page 10. Continue this process for each of the filter sets. 5. Average the velocities and compare to the air velocity shown on the Filter Velocity Chart. The average velocity may be slightly lower or higher providing that it is within the minimum and maximum range as shown on the Filter Velocity Chart. If the air velocity is outside the minimum/maximum range, the performance of the hood will be affected and therefore the exhaust fan must be adjusted.

Using the 16 second averaging feature on the meter, slide the sensing head along the slot, back and forth, accross two or three cartridges, and record the velocity at the end of the 16 second mark. Continue this process for the full length of the hood. Imortant Note: If the hood includes custom air baffles as illustrated in Fig. 11, always take separate readings on the section of the hood that includes custom air from the section that does not have the baffles. Non custom air and custom air readings must be recorded seperately. Do not average them together. 6. Record the velocity (fpm) on the start up inspection report form. A sample report form, which can be photocopied, is provided on page 10. 7. The designed, or optimum velocity, is noted on the shop drawings and the Inlet Velocity Chart. Two velocities will be noted if the ventilator includes custom air baffles. 8. Compare the recorded air velocity to the designed air velocity shown on the shop drawings or the Air Velocity Chart. The recorded velocity may be slightly lower or higher providing that it is within the minimum and maximum range as shown on the Inlet Velocity Chart . If the air velocity is outside the minimum/maximum range, the performance of the hood will be affected and therefore the exhaust fan must be adjusted. Smoke capture and grease extraction efficiency are dependent upon the proper air velocity at the inlet slot of the cartridge extractors. The required average slot velocities are shown on the “Air Velocity Chart” below. If the slot velocity is below the required average, the exhaust fan must be adjusted accordingly. NOTE: The height of the inlet slot can vary depending upon the designed air volume. It is, therefore, important to first measure the inlet slot and compare it to the chart below to determine the required average inlet slot velocity. The designed CFM per lineal foot is related to the velocity as shown on the chart below. The total CFM for the ventilator can be found on the hood nameplate. (See Figure 7,Page 5).

This can result in grease deposits which lead to sanitation problems or fire hazards if left uncorrected. If air velocity readings are higher than those specified, it will require more energy to operate the exhaust fan and excessive noise levels will result. Higher or lower velocities than the required average will normally put the entire heating and ventilating system out of balance. When measuring the air velocity it is very important to take an average reading across the inlet slot plane as described in the instructions. Positioning the sensing head incorrectly will give velocity readings that cannot be compared to the “Inlet Velocity Chart”. FIGURE 11 The standard instrument used for measuring cartridge extractor inlet velocities on a Gaylord Hood is a Pacer, Model DA40 or DA4000 Digital Anemometer. This instrument is the easiest, most accurate and the best suited for measuring hood inlet slot velocities. To take accurate air velocity readings, follow the instructions below. Instructions 1. It is first necessary to determine if the hood includes Custom Air baffles as shown in Fig. 11. If shop drawings are available, and if equipped, the custom baffles and their location will be noted on the front elevation. If not available, to determine if Custom Air baffles are provided, remove one or more cartridge extractors and look along the bottom cartridge track for a Custom Air baffle as shown in Figure 11. 2. If the hood includes Custom Air baffles, it will be necessary to take two sets of readings - one for the section of hood that includes Custom Air baffles and one where it does not. 3. Attach the cable from the sensing head to the meter and the handle sections to the sensing head. 4. Place the sensing head against the lower lip of the cartridge inlet slot as illustrated in Figure 11 and 12. FIGURE 12 7 PARTS LIST ITEM NO. PART NO.
