The primary disadvantage of a ventless fireplace is that it doesn’t have an exterior venting system. This means that the byproducts from combustion are emitted into your home, which raises some safety concerns. In addition, ventless gas fireplaces produce moisture as they burn—and if there’s no ventilation, you could end up with a mold problem.

Regular professional chimney cleaning and a well-fitting chimney cap are two of the most effective measures to help prevent flue blockages. Annual cleaning keeps the flue from developing a thick layer of creosote. The chimney cap keeps debris out and stops critters from going down your flue for shelter while carrying clog-worthy nesting material.

No. Removing the cause of concern will only lead to deeper concern. You cannot use any fire-powered appliance like a fireplace or furnace without an escape route for the smoke and fumes. If you remove the flue intending to repair or replace it, you should only use the fireplace, wood stove, or furnace once the flue is in working order. If you cannot replace the flue you have removed, call a chimney repair professional immediately.

A spark arrestor is not the same as a chimney cap. Both sit on the top of the chimney. However, the cap keeps debris from entering the chimney, and the spark arrestor’s primary function is to prevent burning embers from escaping. Some spark arrestors are integrated into the chimney cap, and others are installed separately.
