摘要： A termination device for a through the wall connection to the double walled coaxial ducting of a horizontal direct vented gas fireplace or the like comprising a mounting means having an opening therethrough for mounting said device on the exterior of a wall having a passage therethrough with the opening registering with the passage, a first pipe adapted for connection with the outer of the coaxial ducts secured to the mounting means and projecting inwardly thereof and adapted to extend through the wall passage, deflector means supported in spaced relation outwardly from the mouth of the first pipe and presenting an air deflecting surface formation surrounding and sloping inwardly towards the mouth of the first pipe to a central opening in substantially coaxial relation with but spaced from the first pipe, said air deflecting surface formation being adapted to deflect air inwardly into the first pipe, a second pipe adapted for connection with the inner of the coaxial ducts extending from an outer end located on the outer side of the deflecting surface formation inwardly through the deflector surface central opening and through the first pipe, means being provided to bar the entrance of foreign objects into the mouth of the first pipe while permitting airflow therethrough, and protective means surrounding the outer end of the second pipe being provided to bar access thereto while permitting escape of exhaust fumes. Preferably the outer end of the second pipe terminates in a cap having a series of peripheral openings therearound and the means surrounding the second pipe comprises a generally spherical chamber having a central band of screening for outletting exhaust products, the inner portion of the chamber facing the mounting plate constituting the air deflecting surface formation.
