Abstract: A flexible chimney liner is presented having a corrugation profile with an sheet strip width of about 110 mm to about 120 mm, preferably about 114 mm and a pitch of about 45 mm to about 55 mm, preferably about 50 mm.

Abstract: A knock-down multi flue chiming cap that has a collapsible cage and separate cap lid. When the cage is fully collapsed, the cage and lid can be easily and safely transported.

Abstract: A process for producing a fume free connector pipe is disclosed. The connector pipe is placed in a curing oven at a start temperature, the oven having a convective air CFM and an intake/exhaust air CFM. The oven temperature is increased over an increase time period to a hold temperature and the connector pipe is heated at the hold temperature for a hold time period then removed from the curing oven after a total amount of time, the total amount of time being the increase time period plus the hold time period.

Abstract: The present invention relates to a dripless chimney cap which prevents condensates from dripping down the outside of a chimney. The dripless chimney cap includes a cone-shaped top cap at the top of the chimney cap for stopping liquids and objects from falling into the chimney. A condensation drip pan in the shape of an inverted cone is positioned below the top cap and functions to catch and collect condensates, directing them toward the inside of the chimney flue. A mounting flange attaches to the chimney and secures the condensation drip pan and top cap to the chimney. A screen mesh located between the condensation drip pan and the mounting flange is designed to allow cross air flow.

Abstract: The present invention relates to a folding chimney flue cap [1000] for fitting chimneys. The folding flue cap [1000] is manufactured as a flat body [1100] having an end panel [1140], a side panel [1160], another end panel [1150], and another side panel [1170], separated by fold lines [1180] between the panels. The folding chimney flue cap [1000] also includes top tabs [1120] above each of these panels. There are also bottom tabs [1130] below each of these panels. The flat body [1100] has a first connector part [1210] at one end and a second connector part [1220] on the other end. The folding flue cap [1000] may be readily shipped in its compact form and assembled into a box shape connecting first connector part [1210] to second connector part [1220]. The top tabs [1120] and the bottom tabs [1130] may be bent either inwardly or outwardly to better match the structures to which it would connect.
