ABSTRACT:
A venting system for the combustion chamber of an oil or gas-fired heating appliance has an elongate diverter box arranged vertically exteriorly of the heating appliance. Such diverter box has an upper end tightly closed off by an insulated imperforate cover and a relief open lower end closed for safety by a perforate grill in which a safety spill switch is mounted. The interior of the diverter box houses a vertically disposed centrally arranged insulated baffle having an upper end in fume tight engagement with cover and a lower free end terminating substantially above the grill. The baffle divides the box into a flue gas inlet section that is connected at the upper portion of the box to the appliance and a vent gas outlet section that is connected at the upper portion of the box to the chimney flue. The inlet section has a turning vane provided on the end wall just below the lower free end of the center baffle. During the burn cycle, the flue gases from the flue outlet of the appliance enter into the upper end portion of the inlet section on one side of the center baffle and travel downward to the lower free end of the baffle before entering the vent outlet section to travel on out the chimney flue.
