摘要： A fireplace cap is positioned outside the firebox of the fireplace. The cap has a framework comprised of first and second side members, an upper cross member and a lower damper section. A pair of hinged doors are mounted to this framework. Dampers selectively control the passage of primary combustion air directly to the firebox. A mantel overlies the upper cross member and a secondary air deflector baffle extends downwardly from the underside of the mantel. This baffle, together with the upper cross member, defines a transversely extending secondary air preheating chamber. Preheated air from the chamber is directed by the baffle across the doors prior to passing into the firebox. In one embodiment, secondary air enters the chamber through a space between the mantel and upper cross member. A valve controls the flow of secondary air to this space. In another embodiment, the damper section and side members define passageways which direct outside combustion air upwardly along the sides of the cap and into the chamber. Valves in the side passageways control the flow of air to the chamber.

摘要： A fireplace cap includes a pair of hinged doors supported by a rectangular framework of first and second side rails, a header section, and a damper section. The components forming the framework are formed with flanges positioned at the rear of the cap for reinforcing purposes and to act as heat exchangers, picking up heat from a fire within the fire box of the fireplace. This cap can be easily custom fit to fireplaces having fire boxes of various sizes by selecting appropriate components for the framework. A top piece mounted to the header section may serve as a cooking surface. The doors may include optional glass plates supported for easy removal by angle members mounted to the back side of the doors. A latching mechanism, including eccentrically mounted latching arms, holds the doors tightly closed when latched. The top piece and side rails define sealing material receiving pockets and include retainers for holding sealing material to seal the cap against the front of the fireplace. Adjustable damper controls, together with an external lever actuated control for the existing damper of the fireplace, are utilized to control the flow of combustion air into the fire box. A removable key or handle is provided for the latching mechanism so that it may be stored in a cool location or out of the reach of children for safety purposes.

摘要翻译： 壁炉盖包括由第一和第二侧轨的矩形框架支撑的一对铰接门，集管部分和阻尼器部分。 形成框架的部件形成有位于盖的后部的凸缘，用于加强目的并用作热交换器，从壁炉的火箱内的火中拾取热量。 通过为框架选择适当的组件，可以轻松地定制适合具有各种尺寸防火箱的壁炉。 安装到头部的顶部件可以用作烹饪表面。 门可以包括可选的玻璃板，其被安装在安装在门的后侧的角部件容易地移除。 包括偏心安装的锁定臂的锁定机构在锁定时将门紧紧地关闭。 顶部和侧部轨道限定了密封材料容纳凹部，并且包括用于保持密封材料的保持器，以将盖子密封在壁炉前部。 可调式阻尼器控制装置以及用于壁炉现有阻尼器的外部杠杆致动控制被用于控制燃烧空气进入消防箱的流动。 提供了一种可拆卸的钥匙或手柄用于锁定机构，以便出于安全目的而将其存放在阴凉处或儿童接触不到的地方。
