                                Q: Hello, I have an old home with coal fireplaces. I have been very pleased with  your C9B vent-free unit (16.5" width).  However, I have one living room fireplace with a 24-inch width. Can you custom make me a coal inset to fit this wider fireplace?

                                A: The C9B consumes the most gas allowed by the unvented heater standard.  To make a wider set, we would need to use more gas in order to provide adequate visual flame, as well as about $20,000 for the design and certification costs.  We will not sell an unvented product that is not certified, so a custom unvented unit is not feasible.  Accordingly, the C9B is the widest CoalFire set we can provide.

                                ventless coal fire
