Rasmussen has designed gas log sets specifically for use in Rumford Fireplaces. The layout of these efficient fireplaces is not well suited for standard gas log sets, for the following reasons:
The height is normally as tall or taller than the width. A vertically-stacked log arrangement best conforms to the lines of the Rumford Fireplace.
The fireplace has a steep taper, in that the rear width of the firebox is much narrower than front width.
The depth is extremely shallow in comparison with traditional fireplaces of similar opening size.
