Benefits of technology

[0008] The present invention relates to vent assemblies that includes intake and exhaust apertures and a vent cap or vent cover. The example vent assemblies are configured to reduce the flow of unwanted liquids into the intake and exhaust apertures. The example vent assemblies can also provide improved fluid flo

Problems solved by technology

However, many of the existing vent caps are not aesthetically pleasing, may get hot due to high temperature exhaust gases, and are exposed to weather conditions and therefore may be damaged.
One disadvantage of many venting units is that they do not adequately compensate for weather conditions.
Wind can create backdraft

Embodiment Construction

[0024] The present invention generally relates to vents, vent covers, vent caps, and vent assemblies. Example embodiments described herein are directed to vent systems and structures that provide improved performance in various weather conditions. The example systems include an exhaust member configured to deliver exhaust fluids from a heating appliance, and an intake member configured to deliver intake air to the heating appliance. The exhaust and intake members are preferably coaxially oriented with the exhaust member extending within the intake member. This coaxial arrangement (sometimes referred to as a B-vent arrangement) may provide cooling of the exhaust gases in the exhaust member by cooling the exhaust member with the intake fluids flowing through the intake member. Other embodiments may include other arrangements of the exhaust and intake members relative to each other.

Abstract

A vent assembly that includes an intake member having an open end, an exhaust member, and a deflector. The exhaust member has an open end and extends coaxially with the intake member. The deflector is positioned along an interior surface of the intake member. The deflector defines a surface that slopes towards the open end of the intake member. The deflector is configured to direct liquid in the intake member towards the open end of the intake duct.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention generally relates to components of a vent system for a heating appliance, and more particularly relates to a vent system having an exhaust vent opening and intake vent opening. [0003] 2. Related Art [0004] Exterior intake and / or exhaust venting systems are generally known for use in buildings and other such structures. Such vents can be used for a variety of venting purposes, for example, to vent fireplaces, furnaces, water heaters, boilers, dryers, exhaust fans, and a many other such appliances and devices. Some such vents are primarily exhaust vents while others are primarily intake vents, and still others include structure that allows them to function as both intake and exhaust vents. [0005] In one example, chimneyless gas fireplaces often include intake / exhaust venting units that are mounted on the outside of an exterior wall that provide a through-the-wall connection to a double walled col...
