Outdoor fireplaces will be constructed of stainless steel to prevent rust and are tested to withstand outdoor conditions. If an indoor fireplace were to be installed outdoors, gas hearth systems would have frequent outages and both wood and gas systems would rust. While the result may not be immediate, standard steel construction would result in a fire over time. Additionally, indoor fireplaces installed in this fashion would never meet approval due to the lack of the appropriate outdoor listing. Subsequently, any damage resulting from installation would not be covered by insurance as all liability would be assumed by the homeowner.
