Abstract
A ceiling support box is an interface for coupling two sections of pipe as part of a venting apparatus for a heating appliance. Dual functionality is provided in a single integrated device by having a vent path for exhausting combustion by-products, and a separate air inlet path to draw in combustion air for use by the heating appliance.
