I am in the process of purchasing a home with a gas furnace. The home inspector mentioned that we should probably have a heat shield on the adjacent wood paneling, as it is fairly close to the furnace itself. What are my options for this?

Thanks for any help you can offer--

You can use unpainted 28 gauge sheet metal to make a heat shield. Fasten it 1" off of the combustable material in question. This is known as the clearance reduction method. Also, no inspector should be able to make you do something that the manufacture of the furnace does not specify. Somewhere on the furnace nameplate it will specify front, back, and sides clearance to any combustables. As long as you are not too close to these measurements, you should be fine. Single- wall flue pipe should be no less than 6". Double- wall no less than 1".
