ABSTRACT:
A coaxial pipe assembly for a direct vent fireplace coaxial flue-system. The coaxial pipe assembly has an inner flue pipe residing within an outer flue pipe where the two pipes are retained to one another. Each flue pipe has a male connector and a female connector with the male connector of the outer flue pipe being aligned with the female end of the inner flue pipe. Lances are formed into the female connector of the outer flue pipe and a locking ridge is formed into the male connector of the outer flue pipe. Each of the two flue pipes of a first coaxial pipe assembly is designed to engage their counterpart in an adjacent coaxial pipe assembly. This engagement seals the adjacent inner flue pipes and is fixed upon the locking ridge passing the lances of a first coaxial pipe assembly to snap into place.
