Grease Locke System "GLS" Commonly Asked Questions

Is the Grease Lock Sysrem (GLS) listed by a nationally recognized testing laboratory (NRTL)?
A Yes. To satisfy fire marshals, building inspectors, and code officials, and to meet NFPA 96 and IMC requirements, the GLS testing was observed by the nationally recognized Intertek ETL laboratory. The Intertek/ETLlisting report is recorded under ETLControl Number 3190996. The Grease Lock System was tested to the UL 1046 Flame-tunnel Test and UL710 abnormal flare-uptest, thereby qualifying the GLS as a "Recognized Component" that"Conforms to UL Std 1046 & ULC-S649-06 Canadian equivalent of UL Std1046" when installed in front of a UL 1046 / ULC 649 metal baffle.
Will the Grease Lock Filter (GLF) catch on fire and spread?
A No, the GLF will not support combustion. Instead of burning freely when touched by flame, the filter chars and smolders. When it is removed from the source of the flame, it will self-extinguish.
Is the Grease Lock System certified by the National SanitationFederation (NSF)?
A No. NSF certification does not apply to disposable products.Therefore, NSF does not apply because the filter is disposable rather than something that is cleaned and reused.
Q How often will I have to change the Grease Lock Filters?
A That depends on the cooking device used under the filter.Because some cooking devices/methods produce more grease particulates than other devices, the filter-changing frequency will vary. The benefit of the GLF is they do not expire with time, so a filter does not have to be changed until it is fully utilized. Also, an initial filter change schedule is provided with the installation of your GLS.
Q Is it safe to change a GLF?
A Yes, the filters can be easily installed and removed from the brackets using the Grease Lock Mounting Tool. They are easily removed from the hood and easily re-mounted while standing on the floor so climbing on equipment or ladders is not required. Additionally, the GLF is non-toxic and made from all natural materials. It is recommended that the filters be changed in the morning prior to heating the cook line to avoid contact with any hot equipment.
Q Will this system create air flow problems within my vent hood?
A No, the GLS has been thoroughly tested and does not create any significant pressure drop airflow problems. Therefore, using the GLS allows you to use your existing fan motor in your hood and does not require a costly replacement for a larger capacity motor.
Q Will the system help keep my duct work clean?
A The GLS is designed to significantly reduce the buildup of grease inside your kitchen hood and ducts, and on your roof.
Q Will I still need to have my ducts cleaned regularly?
A The frequency of cleaning is sometimes regulated by local jurisdictions. You should have your ductwork and extractor cleaned whenever buildup of grease is present. If the GLS is properly maintained then you should experience a much cleaner duct and extended periods between cleaning.
Q Will disposal of used filters create any problems?
A No. The used filters can safely be disposed of in your normal trash receptacle. The GLF fibers are biodegradable with significant benefits accruing from returning it to the earth as a fertilizer, rich in nitrogen and sulfur. (Source: Wool as a Technical Fiber, J.Text.

A During normal cleaning and maintenance, parts of the fan wear and loosen leaving gaps where grease will leak out onto the roof.
Q If I replace my fan will I need to buy a new Grease Gutter?
A Not if the replacement fan is the same size as the original because the Grease Gutter mounts to the curb not the fan itself.
