ABSTRACT:
A combination of metallurgical and vent engineering design solutions that result in a superior product, lower installed cost, and corrosion-free performance for venting modern fan-assisted gas appliances by using a flexible, compressible, corrugated gas vent connector. Preferably the connector is constructed from a material having a heat conductivity substantially equal to or greater than aluminum. Other forms of the invention include the use of stainless steel; a double wall corrugated wall in the flex section; and the use of flat flex in the corrugated section.
By providing the flex connector with twist lock couplings the connector may be assembled in the field more quickly with a greater assurance of its integrity under adverse conditions such as earthquakes or other building moving conditions.
