Abstract:
An outside air intake hood for receiving combustion air deliverable to a fuel-fired heating appliance, comprising:a hollow body having an outer side wall extending between facing first and second inlet openings spaced apart in a first direction and through which outside combustion air may enter the interior of said hollow body, and an outlet passage through which outside combustion air may flow outwardly from the interior of said hollow body, said outlet passage having an open entry portion facing said outer side wall and spaced apart therefrom in a second direction transverse to said first direction;a baffle structure associated with said hollow body and being operative to intercept outside combustion air entering one of said first and second inlet openings in said first direction and deflect the intercepted outside combustion air into said entry portion of said outlet passage; andan air pressure relief bypass passage extending between said first and second inlet openings through the interior of said hollow body outwardly of said open entry portion of said outlet passage, said air pressure relief passage being operative to permit a portion of wind-driven outside combustion air entering one of said first and second inlet openings in said first direction to flow through said pressure relief passage, and be discharged through the other of said first and second inlet openings, without flowing into said open entry portion of said outlet passage.
