Abstract
A termination unit for a through-the-wall horizontal vent of a gas combustion device having a combustion chamber and a burner, is described. The termination unit comprises a wall mounting plate which is secured to a vertical wall outer surface and about an outer sleeve of a coaxial flue pipe. A fresh air chamber is secured to the wall mounting plate. An exhaust end of an exhaust flue pipe extends through the wall mounting plate and the fresh air chamber to exit through an outer wall of the chamber. Air intake ports are provided in an outer peripheral wall of the chamber to supply fresh air to a coaxial passage between the exhaust flue pipe and the outer sleeve to feed the combustion chamber. An air baffle is provided in the chamber about the exhaust end of the flue pipe and extends through the chamber. Wind deflector flanges are disposed in spaced relationship about the air intake ports of the chamber.
