Sample Specification

The grease duct and conduit must meet UL (Underwriters Laboratories Inc.) and c-UL (Underwriters Laboratories of Canada inc.) standards and carry the appropriate approval labels. The maximum temperature must be 500°F (260°C) for continuous operation and the grease duct must have been tested to withstand a 2000°F (1094°C) temperature for thirty minutes.

The grease duct and conduit components must be of double wall construction and properly designed for positive pressure exhaust. The inner wall must be of 20 gauge 304 stainless steel, with continuous plasma welds. The outer wall must be of 24 gauge 304 stainless steel. A ceramic fiber insulation (2 in.) must be installed between walls. The jointing must be made using the assembly band, the finishing band and the appropriate sealing material, as supplied by the manufacturer. Quality required : Model A-IPPL2F.

All components must be installed according to the manufacturer recommendations and must meet the NFPA and local safety code requirements.

Testing

CHEMINÉE LINING.E inc. resources include a test facility specially created to develop, test and demonstrate grease duct fire and leakage resistance. Tests were conducted in the presence of UL inspectors according to UL 1978 standard for grease ducts.
