Wooden Sun only sells and installs fully-vented gas logs (an operational chimney is required), but many people have freestanding gas logs in what are called “unvented fireboxes”. These “fireplaces” are no more than metal boxes set into the wall, and have no chimney that could be used for an insert or replacement logs. This doesn’t mean that you can’t get a new gas appliance, merely that it will change the scope of work required.
