Direct vent fireplace

A gas fireplace comprising:

• a housing located in a building;
• a first conduit extending from outside the building into the housing and comprising a cylinder having first and second groups of longitudinal openings at its outer end;
• a fireplace insert received in the housing;
• a second conduit in the fireplace insert alignable with and received by the first conduit, the first and second conduits being dimensioned so that the second conduit extends to a point between the two groups of longitudinal openings of the first conduit;
• a gasket located between the first conduit and the second conduit and contacting the first conduit between the two groups of longitudinal openings;
• a generally conical closure for the first conduit located in the end of the first conduit to seal the end of the first conduit and extending into the first conduit to a point adjacent the end of the second conduit, the gasket and conical enclosure cooperating to define an annular air inlet extending from the second group of openings in the first conduit between the first and second conduits and an exhaust outlet in the second conduit extending to the first group of openings in the first conduit, the conical closure acting to deflect exhaust gases from the second conduit through the second openings;
• the housing being located independently of the fireplace insert initially and the fireplace insert being inserted subsequently by alignment of the second conduit within the first conduit, the first conduit and the gasket co-operating to guide and control movement of the second conduit thereby guiding insertion of the insert within the housing.
