VIP+ is a modular, double wall chimney system designed to vent positive pressure appliances. The prefabricated design has a sealed flue capable of containing pressure up to 60 inches of water column and is built to operate at continuous temperatures up to 1400˚F. This system is certified for UL103, UL1978, UL2561 et ULC/ORD-C959.
It is suitable to vent:
- – Stationary engines such as generators or turbines
- – Furnaces and boilers
- – Industrial ovens and process equipment
- – Combustion gasses or heated air
- – Restaurant hoods
The inner liner has a continuous butt-weld seam for a high degree of tolerance and a tight fit. It made of either type 304 or 316 stainless steel. The outer casing has an overlap resistance welded seam that is gas- and watertight. It can be made of type 304 stainless steel, 316 stainless steel, or Galvalume steel.
Available in the following diameters:
6, 8, 10, 12, 14, 16, 18, 20, 22 and 24 inches
VIP+ is designed with an overlapping male-female joint. Lengths align easily and seal tightly at all connections. Each length includes an inner locking band which provides structural strength and holds the assembled parts together. The inner locking band also encapsulates the sealant required for a leak-free system. This connection method greatly reduces labor, especially on the horizontal portion of the installation. Access to the inner locking band is made possible by a 6-inch gap in the outer casing; an outer band bridges the gap. Insulated systems include a strip of insulation which must be installed inside the outer band. Every component that is in contact with the flue gasses has the inner and outer locking band pre-installed. For insulated systems, an additional insulation wrap is included to fill the void.
