Sheet Metal  heatfab Saf-T Vent CI Plus


AL29-4C Superferritic Stainless Steel for Category I, II, III, IV Appliances.

Saf-T Vent CI Plus combines the tightfit of the tapered male and female expands with a patented clousure system which consists of tabs and a locking strap.

The double-wall construction allows for an insulating blanket of 1" air space between the inner wall and the outer wall. This air insulation has the advantage of keeping the flue gases warmer as well as making the skin temperature of the outer wall cooler.
