ABSTRACT:
An air terminal for a horizontal vent of a sealed combustion furnace includes a faceplate for mounting to an exterior vertical wall. A horizontal flue pipe extension, receiving the combustion products, is surrounded by an oval sleeve. Fresh air is communicated to the furnace through the space between the flue pipe and the sleeve. The outlet of the flue pipe is at least about 3/4 in. outside the faceplate. An enlarged fresh air intake opening exists about the flue pipe, and a pocket-shaped rain shield is located beneath the flue pipe extending upwardly and inwardly. A horizontal wind deflector vane is located beneath the flue pipe and extends across the width of the fresh air intake opening for directing incident wind downwardly along the wall. The terminal improves operation of the furnace under all wind conditions, whether the furnace is operating on pilot or main burner modes.
