A grease fire starts if hot cooking oil comes into contact with a heat source, such as an electric heating element or the flame on a gas range. Once the grease is ignited, it can be very difficult to put out. 

A chimney liner isn’t required for an outdoor fireplace; you don’t technically need one if the masonry chimney uses the proper dimensions and is built to code. However, a chimney liner does serve as a protective coating for the flue. Adding a liner could improve performance, safety, and durability. In short, while not necessary, it wouldn’t hurt.

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.

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.
