Saf-T Vent® SC DOUBLE WALL SPECIAL GAS VENT Introduction: Saf-T Vent SC is an advanced concentric vent system designed for zero clearance installation in residential and light commercial applications. The inner wall is constructed from superferritic AL 29-4C®. The outer wall is stainless steel, providing durability and a lasting finish.
Saf-T Vent® SC DOUBLE WALL SPECIAL GAS VENT Accessories: Vertical/Horizontal In-Line Drain Section — Use to drain away condensate from the vent system. The unique design of this part allows it to be installed in a horizontal, vertical or inclined orientation. Continuous horizontal runs in excess of 30 feet require a condensate drain. Drains may also be required by the manufacturer. High temperature silicone rubber tubing is available separately, see below.
Saf-T Vent® SC DOUBLE WALL SPECIAL GAS VENT Adapters: Single Wall Adapter/Appliance Adapter — Use to transition from single-wall to Saf-T Vent SC. The male end connects to Saf-T Vent EZ Seal or Saf-T Vent appliance adapters and flue collars. The outer diameter collar is vented and must not be blocked during installation or operation.
Saf-T Vent® SC DOUBLE WALL SPECIAL GAS VENT Elbows: 45° Elbow — Use to achieve offsets or changes in the direction of the vent system. The degree of these welded seam elbows is not adjustable.

Saf-T Vent® SC DOUBLE WALL SPECIAL GAS VENT Straight Lengths: Install vent with a continuous pitch of 1/4" per foot, sloping upward toward the termination (unless otherwise specified by the appliance manufacturer). It is important to provide adequate support to a Saf-T Vent SC system. Refer to installation instructions for support specifications.
Saf-T Vent® SC DOUBLE WALL SPECIAL GAS VENT Supports: Vertical Support Leg — For use on vertical systems to provide support. The 20-gauge stainless steel support legs can be used below or above the roof, and can be used in pairs for extra stabilization. Hardware to attach the support to the structure is not provided; attach using best construction methods. Be sure to consider clearances when planning the system. Never drill or screw through the Saf-T Vent SC inner vent conduit.
Saf-T Vent® SC DOUBLE WALL SPECIAL GAS VENT Termination Accessories: Fire Stop / Support / Wall Plate— A fire stop may be required anytime Saf-T Vent SC penetrates combustible floors, walls, or ceilings. Remove any insulating material from the floor, wall, or ceiling cavity for at least 1 inch around the vent. Review fire codes and consult with local building code officials to determine the necessity for a firestop. This part provides added support when used at the bottom of a vertical chase.
