Abstract
A venting system and a method for installing the venting system. A non-flexible metallic venting pipe comprises a chase. A first end of the vent pipe is positioned adjacent an appliance installation and a second end positioned at an exit to an external region of a home. A flexible vent tube comprising a sealed non-corrosive material, having a first end and a second end, is positioned between the first end of the venting pipe and the second end of the venting pipe. Adapters are positioned at the ends of the venting pipe. A method comprises routing a flexible venting tube comprising sealed, corrosion resistant venting material through an existing non-flexible double-walled vent comprising non-sealed material.
Claims9
A venting system comprising:
- a non-flexible metallic venting pipe comprising a chase, having a first end positioned adjacent an appliance installation and a second end positioned at an exit to an external region of a home, the metallic venting pipe having a first diameter adapted to couple to a vent cap at the second end, the vent cap having a reciprocal diameter adapted to mate with the first diameter, the first diameter adapted to mate directly to an exhaust of a first type of combustion appliance at the first end;
- a flexible stainless steel vent tube comprising a non-corrosive metal, having a first end and a second end, the vent tube positioned between the first end of the venting pipe and the second end of the venting pipe, the vent tube having a second diameter smaller than the first diameter, the second diameter adapted to couple directly to an exhaust of a second type of combustion appliance and mate with the vent cap to provide an exhaust path between the exhaust of the second type of combustion appliance and the vent cap;
- and
- the vent tube comprising a material to allow condensate from the appliance to remain within the vent tube under positive and negative venting pressure when the vent tube is coupled to the exhaust.
A venting system comprising:
- a flexible steel vent tube comprising a sealed non-corrosive steel, having a first end and a second end, the vent tube positioned in a non-flexible metallic venting pipe comprising a chase, the chase having a first end positioned adjacent an appliance installation and a second end positioned at an exit to an external region of a home, the vent tube having a second end positioned at the exit to an external region of a home, the metallic venting pipe having a first diameter adapted to couple to a first vent cap at the second end, the vent cap having a reciprocal diameter adapted to mate with the first diameter, the first diameter adapted to mate directly to an exhaust of a first type of combustion appliance at the first end, the flexible steel vent tube having a second diameter smaller than the first diameter, the second diameter adapted to couple directly to an exhaust of a second type of combustion appliance and mate with the vent cap to provide an exhaust path between the exhaust of the second type of combustion appliance and the vent cap;
- the vent tube comprised of a non-corrosive material to thereby allow condensate from the appliance within the vent tube under positive and negative venting pressure.
