Abstract
A flue damper may include a vent pipe with a first side leading to an outlet of the flue damper and a second side leading to an inlet of the flue damper. A damper gate of the flue damper may be movable between an open state and a closed state, where in the open state, the first side of the vent pipe is in fluid communication with the second side, and where in the closed state, the damper gate interrupts fluid communication between the first side and the second side. A drainage port may also be included, and a plug may be movable relative to the drainage port to selectively seal the drainage port when the damper gate remains in the closed state.
Claims20
A flue damper, comprising:
- a vent pipe with a first side leading to an outlet of the flue damper and a second side leading to an inlet of the flue damper;
- a damper gate coupled, via a hinge, to a portion of the flue pipe, the damper gate comprising an open state and a closed state, wherein in the open state, the first side of the vent pipe is in fluid communication with the second side, and wherein in the closed state, the damper gate interrupts fluid communication between the first side and the second side;
- a drainage port;
- and
- a plug that is movable relative to the drainage port to selectively seal the drainage port when the damper gate remains in the closed state.
A flue damper, comprising:
- a vent pipe with a first side leading to an outlet of the flue damper and a second side leading to an inlet of the flue damper;
- a damper gate coupled, via a hinge, to a portion of the flue pipe, the damper gate comprising an open state and a closed state, wherein in the open state, the first side of the vent pipe is in fluid communication with the second side, and wherein in the closed state, the damper gate interrupts fluid communication between the first side and the second side;
- and
- a drainage port, wherein the drainage port forms an opening extending through the damper gate.
A flue damper, comprising:
- a vent pipe with a first side leading to an outlet of the flue damper and a second side leading to an inlet of the flue damper;
- a housing that is coupled to the vent pipe and that is positioned between the first side and the second side, the housing comprising:
- an opening fluidly connecting the first side and the second side;
- and
- a wall peripheral to the opening;
- a damper gate coupled to the housing and comprising an open state and a closed state, wherein in the open state, the first side of the vent pipe is, via the opening, in fluid communication with the second side, and wherein in the closed state, the damper gate, by covering the opening, interrupts fluid communication between the first side and the second side;
- a drainage port extending through the wall of the housing, wherein the drainage port is offset from the damper gate and the opening.
