What size firebox is necessary for 30-inch ventless logs? Can a firebox be built by a mason?
For a ventless gas log set, the firebox may not be built by a mason unless it's a fully-functional wood-burning fireplace, which means a chimney would have to be constructed as well. A ventless gas log set may only be installed into an existing fully-functional wood fireplace or a ventless firebox with inner opening measurements that meet or exceed the minimum opening requirements described in the product literature included with the gas burner. Subsequently, we'd have to know the make and model number of the log set in order to recommend a suitable ventless gas firebox.
