Abstract: An artificial log assembly is disclosed. The artificial log assembly includes first and second concrete portions and a ceramic portion disposed between the first and second concrete portions. The concrete portions are easily and economically formed to an appearance of natural firewood, and the ceramic portion provides a "glowing effect" of burning embers when heated. Also disclosed is a log assembly system utilizing dual gas burners of different flame temperatures.

Abstract: A coaxial pipe assembly for a direct vent fireplace coaxial flue-system. The coaxial pipe assembly has an inner flue pipe residing within an outer flue pipe where the two pipes are retained to one another. Each flue pipe has a male connector and a female connector with the male connector of the outer flue pipe being aligned with the female end of the inner flue pipe. Lances are formed into the female connector of the outer flue pipe and a locking ridge is formed into the male connector of the outer flue pipe. Each of the two flue pipes of a first coaxial pipe assembly is designed to engage their counterpart in an adjacent coaxial pipe assembly. This engagement seals the adjacent inner flue pipes and is fixed upon the locking ridge passing the lances of a first coaxial pipe assembly to snap into place.

Abstract translation: 一种用于直接排气壁炉同轴烟道系统的同轴管道组件。 同轴管组件具有位于外烟道内的内烟道管，其中两管彼此保持。 每个烟道管具有阳连接器和阴连接器，外烟道的阳连接器与内烟道管的阴端对准。 喷枪形成在外烟道管的阴连接器中，并且锁定脊形成在外烟道管的阳连接器中。 第一同轴管组件的两个烟道管中的每一个被设计成与相邻同轴管组件中的对应物接合。 该接合件密封相邻的内部烟道，并且固定在通过第一同轴管道组件的矛杆的锁定脊上以卡入到位。
