Double Wall
Saf-T Vent CI Plus is the leading commercial double-wall UL 1738 special gas vent system for condensing heating appliances, made from superferritic stainless steel. With 1″ airspace (and optional 1″ fiber blanket) between the inner wall and the outer wall, CI Plus reduces the required clearance to combustibles and has lower skin temperatures.
The joint seal is securely fastened together at the inner wall and not the outer wall like some other double wall manufacturers, for increased strength & security. Our overlapping male-female joint also ensures the acidic condensate stays on the extremely credible, durable AL29-4C® stainless steel when installed properly. The aesthetic mirror-like stainless outerwall provides a professional look like no other and has even been used for commercial beer brew kettle steam exhaust.
