Saf-T Vent CI
The Heat-fab Saf-T Vent® CI, a Special Gas Vent, is an AL 29-4C® stainless-steel inner wall double-wall venting system designed for use with any Listed Category I, II, III, or IV gas-fired appliance. The Saf-T Vent CI system is ideal for mid- and high-efficiency commercial and industrial natural gas and propane fired equipment with condensing flue gases and for systems with positive-pressure venting requirements.
A high-quality, extremely durable, corrosion-resistant system, Saf-T Vent CI consists of a flue-gas conduit and an outer jacket, with an insulating air space of approximately 0.16" between the conduit and jacket. The conduit (inner liner) is fabricated from highly corrosion-resistant AL 29-4C stainless steel, and the outer jacket is constructed of Type 430 stainless steel. Type 316L stainless-steel outer jacket is available for required applications.
Saf-T Vent CI Uses:
Primarily used in applications where Listed Category II, III, or IV or Direct Vent gas-fired appliances produce condensation that will corrode most common chimney and venting materials.
Also effectively used in applications where positive-pressure venting systems are required or specified. The Saf-T Vent CI closure system is tested to be gas tight at two and one-half times the Listed pressure rating of 3" water column (pressure: positive up to 3" wc, negative, or neutral).
For installations with close installation tolerances and venting clearances, Saf-T Vent CI double-wall construction reduces the necessary space for clearance to combustible materials. (See Installation Instructions for required clearance to combustibles and installation restrictions). |
