PRINCIPLES OF OPERATION

UV Lamps

Systems incorporating UV lamps will have the extra added 
benefit of further break down of grease, in some cases down 
to  CO2,  H20,  and  base  minerals.    The  processes  called 
“Photolytic  Oxidation”,  and  “Ozonolysis”  are  the  drivers 
behind keeping your ducts clean and free of containments 
for much greater durations over conventional kitchen exhaust 
systems  not  utilizing  the  UVC  technology.   The  processes 
break down, and condition grease dramatically reducing its 
ability to burn or in some cases even combust.  For proper 
UV operation, the hoods must be maintained in good working 
order.  UV Lamps will accumulate a light gray dust on them 
that will have to be periodically wiped off from below.  Duct 
work will have to be inspected in accordance with NFPA-96 
or local guidelines, though frequency of duct cleanings will 
be dramatically reduced.

Important Notice:

 Never operate your Ventilator without 

the XG Extractors in place.  The XG extractors are UL 1046 
Flame Exposure tested to protect you’re your system from 
penetration of fire into the exhaust duct.  The XG Extractor is 
also a light attenuation barrier to remain in place at all times 
during the use of your UV system.

Cleaning

At the end of each cooking day the fan is to be turned off and 
the XG Extractors are to be safely removed from the hood 
and cleaned.  The 

“XG” Extractors

 can be washed either 

in a dishwasher or soaked and rinsed off.  The XG filter has 
a  unique  dual  hinge  design  that  will  allow  the  extractor  to 
be  opened  so  its  internal  components  are  accessible  for 
cleaning.  Periodic internal scrubbing of the extractors may 
be necessary in lines servicing busy kitchens, or lines using 
sugary sauces or bastings.

The 

UV lamps

 will develop a coating of dust, and sometimes 

debris  that  will  have  to  be  periodically  wiped  away  to 
optimize the UVC Systems performance.  The lamps should 
be  inspected  weekly  once  the  filters  are  removed.   When 
necessary, the lamps can be cleaned from below by carefully 
wiping the bulbs with a wet cloth using some mild detergent.  
A  maintenance  rotation  should  be  initiated  at  the  point  of 
start up by a Gaylord Industries certified Service Agent to 
address  any  maintenance,  or  repair  issues  that  may  be 
required.

Fire Protection

NFPA-96  Requires  the  use  of  Surface  Fire  Protection 

(Duct, Plenum, Surface/Appliance)

 on all hoods.  It is these 

systems that are the first line of defense against equipment 
fires.  Refer to the fire extinguishing systems owner’s manual 
for  operation  and  maintenance  instruction  of  for  these 
systems.

The 

XG-GFBD

  Series  ventilator  incorporates  a  fire  / 

balancing damper in stalled in the duct collar to protect your 
ducts, fans, and roof tops from the threat of fire in the event 
your primary fire protection system fails to extinguish the fire.  
In  the  event  of  a  fire  when  the  thermostat  reaches  its  set 
point of 325°F, the power to the hood will be cut allowing the 
dual blade damper to spring shut sealing the duct entrance 
and keeping the fire contained in the plenum, where it can 
be  properly  managed.    Exhaust  dampers  are  an  excellent 
way to protect your roof top and un-maintained grease ducts 
from the threat of fire. 

The hood may also be supplied without a fire damper, which 
would be designated by either the suffix 

“ND”

 or 

GBD

 in the 

model number.  

GBD

 designates a balancing ONLY damper.  

Refer  to  the  nameplate  on  the  hood  for  the  exact  model 
number designation.
