Ansul has received formal UL acceptance of these new enhancements and we now authorize the use of the new protection and coverages. Once again, noted below are the new enhancements. • Duct — Duct protection has increased to 100 in. perimeter (254 cm) - the longest side 34 in. (86 cm) or 31 7/8 in. (81 cm) diameter or less, using one 2W nozzle. Also, using one 1100 nozzle will give duct protection of 50 in. perimeter (127 cm) - longest side 17 in. (43 cm) maximum or 16 in. (40.6 cm) diameter or less. Pricing for the 1100 nozzle is as follows... Suggested Part No. Description List Price 430913 Nozzle, 1100, 25 /package (Pkg. Price) $576.00 • Note: Part No. 430913 (1100 Nozzle) will be available June 10, 2002. • Plenum — Plenum protection is increased to 10 ft. long by 4 ft. wide (3 m x 1.2 m) using one 1N nozzle on a Single -Bank Plenum or by using two 1N nozzles on a "V' Bank Plenum. • Detection — Each cooking appliance with a continuous cooking surface not exceeding 48 in. x 48 in. (122 x 122 cm) can be protected by a minimum of one detector. Cooking appliances with a continuous cooking surface exceeding 48 in. x 48 in. must be protected by at least one detector per 48 in. x 48 in. cooking hazard area. Detectors used for cooking appliances must be located within the perimeter of the protected appliance toward the exhaust duct side of the appliance. The detector should be located in the air stream of the appliance to enhance system response time. Refer to the R -102 manual for additional detector limitations. • Gas - Radiant Char - Broiler — Coverage has increased using one 1N nozzle, which will protect a hazard with a maximum length of 36 in. (91 cm) and a total cooking area that does not exceed 864 sq. in. (5574 sq. cm). The nozzle tip must be located 15 to 40 in. (38 to 102 cm) above the hazard surface and positioned anywhere along or within the perimeter of the maximum cooking area and aimed at the center of the cooking surface. • 05/30/2002 03:26AM FAXCOM . • • • • ••• • • • • 1, • •� • N • • ••• • • ••••• • / • • :19, :• • • •• •• ••• o p . i • • • • • • 0• • • •• General Bulletin No. 4525 • • • • • • # • • f; May 29, 2002 ••• ,,,• • • • • . • • • •• • Page 2 • • • • • • •: •• • •• •• •• . • • • • ••• •• • • • • • ••• • • • • • • • • • • of" • Wok — Coverage is enhanced to protect a wok 11 in.
