Sample Specification (Boiler Exhaust)

The chimney and flue must meet ULC (Underwriters Laboratories of Canada) and UL-103 (Underwriters Laboratories Inc.) section 22A for positive pressure exhaust system up to 60” water column and carry the appropriate approval labels. The chimney shall be listed by UL as a “B.H.A.” (Building heating appliance) chimney for continuous operation up to 1000°F (540°C) maximum. For applications above 1000°F (540°C), the chimney shall be listed by UL as a “1400°F chimney” for continuous operation up to 1400°F (760°C) maximum.

The chimney and flue components must be of double wall construction and properly designed for positive pressure exhaust. The inner wall must be of 20 gauge (18 gauge – 42” to 48” diameter) 304 stainless steel, with continuous plasma welds. The outer wall must be of 24 gauge (20 gauge – 42” to 48” diameter) 304 stainless steel. A high temperature insulation (2 in.) must be installed between walls. The jointing must be made using an assembly band, a finishing band and an appropriate sealing material, as supplied by the manufacturer. Quality required : Model IPPL2.

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