Fireplace/Gas to Wood

Posted by firebelly (My Page) on

I have a prefab metal fireplace that was installed when I had the house built-woodburning. I converted it to gas a few years ago, and in doing so had to knock out a plug that was in the refractory wall, that was made just for that purpose-for running a gas line inside. Well, I want to use wood again since the gas logs are no longer good. The only problem I have is that I have that hole in the refractory wall. Is there any way to plug that hole? If so, what are my options. I called the builder supply company that the fireplace came from, and the first thing they told me was that I needed to buy a whole new refractory-floor, back and both side walls. They are known for upselling and hard sell tactics. Even if I did do that though, the fireplace is 11 years old, and I don't know if I could even get the refractory since the company is out of business (Martin). Anyone got any ideas. I went to Lowes and saw several types of silicone fire block and heat resistant caulk, and even a fire retardant "foam". Help!

RE: Fireplace/Gas to Wood

I suppose that anything other than replacing the board with the hole in it would void the manufacturer's warrentee the the fireplace will operate safely.

But really, this isn't rocket science. The idea is to prevent coals from migrating into the combustible materials behind the fireplace. So if you are willing to take a small risk, patching the hole with a suitable fireproof mortar or patching in a piece of firebrick ought to be safe enough.
