The interior housing forms a combustion chamber. The fireplace also comprises a top wall, a rear wall and side walls. These walls define an exterior housing about the combustion chamber. A combustion air flowpath is defined within the housing through which air for combustion is brought from outside the housing into the combustion chamber. The fireplace also comprises a top port formed in the top wall and a rear port formed in the rear wall. Each of the top and rear ports include a first portion that communicates with the combustion chamber and a second portion that communicates with the combustion air flowpath. Finally, the fireplace comprises a vent pipe assembly. The vent pipe assembly includes an inlet air pipe member and an outlet air pipe member. The outlet air pipe member is connectable with the selected port at the first portion.
