Frequently Asked Questions (FAQ's)
|
- How are tilt skillets and tilt braising pans protected?
- At what point does an existing dry chemical or wet chemical system need to be upgraded to a UL 300 wet chemical system?
- Can carbon dioxide cartridges be used instead of nitrogen in pre-UL 300, R-102™ systems?
- Can the Hose/Grommet Pkg. (Part No. 418511) be used to connect to an add-on tank with painted bracket? Also, do you have to manifold two tanks together to use the Hose/Grommet Pkg.?
- How are industrial fryers (potato chip, corn chip, pork rind, etc.) or large donut fryers protected?
- How are ranges protected when a shelf or salamander broiler is installed above the back of the range?
- How are tilt skillets and tilt braising pans protected?
Currently, there is no UL test for tilt skillets and braising pans. However, UL has stated that because these appliances can be used for frying, they must be protected as fryers. Multiple nozzle protection for fryers is limited by UL to fry vats not exceeding 6 sq. ft. (864 sq. in.). This limitation does not apply when multiple nozzle protection is used for tilt skillets and braising pans. Also, because tilt skillets/braising pans do not have insulated sides to the cooking pan, the maximum dimensions (area and longest side) for fryers with drip boards, can be used.
- At what point does an existing dry chemical or wet chemical system need to be upgraded to a UL 300 wet chemical system?
Answer UL 300 changes affect only pre-engineered restaurant fire suppression systems manufactured after November 20, 1994. All existing R-102 installed systems are "grand fathered" and remain listed using the UL guidelines in effect at the time of manufacture (R-101 Dry Chemical System service and replacement components are no longer available. Consequently, this system is no longer listed, according to Underwriter’s Laboratories (UL)). Although local jurisdiction or code writing bodies may dictate otherwise, previously listed fire suppression equipment is not required by UL to be upgraded to UL 300 even if the cooking line has been changed. However, this does not imply either, by UL or Ansul, that it is not necessary to evaluate your current restaurant fire protection system. To ensure the best fire protection available in applications where vegetable oil is used in depths greater than 1/4", a UL 300, R-102, or PIRANHA wet chemical fire suppression system should be used.
- Can carbon dioxide cartridges be used instead of nitrogen in pre-UL 300, R-102™ systems?
No. Even though the system may operate satisfactorily, pre-UL 300 R-102 systems still require the use of nitrogen cartridges to comply with their listings.
- Can the Hose/Grommet Pkg. (Part No. 418511) be used to connect to an add-on tank with painted bracket? Also, do you have to manifold two tanks together to use the Hose/Grommet Pkg.?
The Hose/Grommet Pkg. can be used with the add-on tank in the stainless steel enclosure, or an add-on tank in a painted bracket (if acceptable to the Authority Having Jurisdiction). The Hose/Grommet Pkg. can be utilized either with manifolded agent discharge piping or when two tanks are piped separately.
- How are industrial fryers (potato chip, corn chip, pork rind, etc.) or large donut fryers protected?
UL will not allow multiple nozzle protection for fryers that exceed 6 sq. ft. (864 sq. in.)* unless the fire suppression system manufacturer obtains a listing for the protection of the specific appliance brand and model number of the fryer (i.e., Krispy Kreme Fryers – Models 150 D/H, 270 D/H, 600 D/H, and 1000 D/H). As an alternative, an engineered carbon dioxide system may be used when designed in accordance with NFPA 12. Under certain conditions, a PIRANHA wet chemical system may be used. Contact Ansul Technical Services for assistance.)
*NOTE: This limitation does not apply when multiple nozzle protection is used for tilt skillets and braising pans. (See question number one.)
- How are ranges protected when a shelf or salamander broiler is installed above the back of the range?
UL has designed a test for ranges that have shelves installed. Shelves and salamander broilers can obstruct the discharge pattern of a nozzle when it is installed over the center of the range. Therefore, a low proximity nozzle(s) must be used under a salamander or shelf. Or, a specifically listed nozzle designed to protect a range when a shelf is present must be used.
