Hi, I just purchased a quad cb 1200i. I have a question regarding clearances, specifically with the mantel. My mantel shelf is probably 5 feet high, posing no clearance problem. However, the surround goes down from the shelf quite a bit. The user manual states that the mantel should be 12 inches from the top of the stove. The beginning of the wood surround, however, would only be 10 - 11 inches above the stove. Is this an issue? What would you recommend I do if this is an issue. I've attached both the owner's manual and a pic of the fireplace to illustrate. This is my first post. I've been reading for a few days. Great site. Thanks.
