Design

All our double wall chimney systems are part of a large family of IPP (Industrial Positive Pressure) products for industrial and commercial applications. The components of each model are made using the same plasma-welded stainless steel inner wall. Since all components have the same small and large ends, the parts of all models fit into one another, thus eliminating the need for all kinds of adapters and providing an incomparable flexibility in selecting models of flues and chimneys.

IPP: single wall	IPPL: double wall with 2” air space
IPPL2: double wall with 2” mineral fiber insul.	IPPL2F: double wall with 2” ceramic fiber insul.

This unique method for jointing components together is very efficient either in horizontal or in vertical installations. Our simple jointing concept along with the wide variety of components and accessories allows for a quick and simple installation, thus permitting you to save both time and money.

Cheminée Lining is proud of their industrial positive pressure piping systems. Recognized for being high quality products, they are also the easiest to install on the market!

These chimney systems are designed for exhaust of combustion gases, under positive, negative or neutral pressure, emanating from a variety of appliances including but not limited to:

• Diesel Engine and Gas Turbine Exhaust
• Industrial Oven Exhaust
• Restaurant Grease Duct
• Boiler Negative and Positive Pressure
• Incinerator
• Unit Heater
• Coffee Roaster
• Heat Recovery
• Air and Product Containment
• Gas and oil powered furnaces and boilers

Models IPPL, IPPL2 and IPPL2F provide a wide variety of components and accessories, suitable for all kinds of site conditions, thus allowing for quick and simple installation. Each component is packed and shipped complete, with (1) one assembly band and (1) one finishing band for those having large ends. Sufficient tubes of appropriate sealant are also included in the shipment for completing the assembly.

LTS: Low Temperature Sealant. 600¾F maximum flue gas temperature HTS: High Temperature Sealant. Up to 2000¾F flue gas temperature ES: Exterior Sealant. Outer sealant weather proof

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.
