Abstract: A flue damper may include a flue 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 may be included and have an open state and a closed state, where in the open state, the first side of the flue 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 float may be secured to an upper surface of the damper gate. The upper surface of the damper gate may face the first side of the flue pipe when the damper gate is in the closed state such that the damper gate at least partially opens when condensate collects within the first side of the flue pipe.

Abstract: A screen cover for attaching to an open end of a conduit of a water heater is provided. The screen cover includes a first diametric portion having a first diameter and a second diametric portion having a second diameter. The first diameter is greater than the second diameter. The first and second diametric portions are coaxially aligned and configured to allow flow of air or gas therethrough. The screen cover includes a shoulder portion defined between the first diametric portion and the second diametric portion. The screen cover further includes a mesh disposed at a first opening of the first diametric portion. The mesh prevents entry of external objects into the water heater through the open end of the conduit.
