Can I use this ventless fireplace with propane or should I order a direct vent fireplace?

You are able to use either a ventless or direct vent fireplace with propane gas. The most significant difference between the two is that a direct vent fireplace will require an vent. A ventless operates at 99.9% efficience and does not require a vent pipe. Each has pros and cons. Please give us a call if we can help further. Thanks!
