Abstract
To flash a hot gas vent pipe, representatively a chimney pipe, extending upwardly through a roof opening, a tubular sleeve having vertically extending spacer members interiorly secured thereto, with upper ends projecting above the upper sleeve end, is concentrically placed around the chimney pipe and anchored to the roof. A rubber boot is then placed around the sleeve and secured to the roof. Finally, a storm collar is downwardly telescoped onto the chimney pipe and rests on the upper end of the sleeve spacer members. Vertical cooling passages are defined between adjacent spacer member pairs, and through their interiors, and have upper exit portions communicating with the storm collar interior.
Claims21
A flashed vent conduit structure extending through a roof opening and comprising:
- a vent conduit through which hot gas may be vented to atmosphere, said vent conduit having an upper end portion vertically extending through the roof opening;
- an open-ended sleeve member coaxially circumscribing said upper end portion of said vent conduit in a horizontally outwardly spaced relationship therewith, said sleeve member having an upper end;
- circumferentially spaced, vertically elongated spacer members disposed between said vent conduit and said sleeve member and laterally extending therebetween in a manner such that vertical cooling passages are defined between circumferentially adjacent pairs of said spacer members, and vertical cooling passages are also defined within said spacer members;
- circumferentially spaced connection members extending laterally outwardly from said sleeve member and interconnecting said sleeve member and portions of the roof bordering the opening therein;
- a resilient flashing boot closely receiving said sleeve member and operatively secured to the roof;
- and
- a storm collar through which said vent conduit upwardly extends, said storm collar having an upper end supported in an upwardly spaced relationship with the upper end of said sleeve, the interior of said storm collar defining a downwardly opening outlet for upper end portions of said vertical cooling passages.
A flashing adapter kit useable in conjunction with a rubber flashing boot to flash a vent conduit extending through an opening in a roof and adapted to vent hot gas to atmosphere, said flashing adapter kit comprising:
- a sleeve structure useable to define a sleeve member outwardly circumscribing the vent conduit and having an upper end, and being operatively receivable in a rubber flashing boot;
- elongated spacer members having associated securement structures useable to secure said spacer members on an interior surface portion of the sleeve member in a circumferentially spaced array in which said spacer members longitudinally extend vertically along the outer surface of the vent conduit, in a manner holding the sleeve member in a concentric relationship with the vent conduit and defining vertically extending cooling passages between circumferentially adjacent pairs of said. spacer members, with upper ends of said cooling passages opening outwardly through said upper end of said sleeve structure;
- each of said spacer members has a hollow configuration and defines in its interior a vertically extending cooling passage when operatively installed within said sleeve member;
- and
- connection members interconnectable between the sleeve member and the roof to hold the sleeve member in a predetermined orientation relative to the roof opening periphery and brace the sleeve member, and thus the chimney pipe, against wind loads.
