The average costs associated with installing a gas fireplace include $600 for the firebox installation, $750 for the vent pipe, $2,750 for the full installation and finishing work, and between $150 and $800 for the gas line, depending on how far it needs to run.

A chimney or flue isn’t necessary. In fact, ventless fireplaces generally are just for aesthetics and supplemental space heating. Ventless fireplaces are not allowed in Canada. Canadians use electric fireplaces for aesthetics.
