Superior White Stacked Refractory Panel Kit for 43 Inch WRT3500 Fireplaces

This kit will not fit a Superior 43-B fireplace. The F3437 panel kit is a factory replacement specifically designed for the 43-inch Superior WRT3500 series firebox, and its panels are cast to the exact shape of that firebox, making them non-interchangeable with other Superior models.

We are unable to match a 43-B to a Superior firebox in our product data, as that number may be a partial model designation. Please provide the complete model and serial number as they appear on the rating plate inside your fireplace, along with whether the unit is wood-burning or gas. This tag is typically a metal or foil label located on the upper inside wall of the firebox or behind the lower louver. With the full model number, we can determine if Superior still produces a factory panel kit for your firebox. If discontinued, we will search for a suitable alternative.

For older, factory-built wood-burning models where factory panels are no longer available, we offer universal, cut-to-fit refractory panels: Hargrove 28 Inch Replacement Fireplace Refractory Panel - Single Pack and Hargrove 40 Inch Replacement Fireplace Refractory Panel - Double Pack. These are flat panels, not pre-shaped sets, so each piece must be cut to size using a masonry blade or wet tile saw. You will need to order enough panel material to cover the areas you are replacing.

Please include your shipping zip code with the model information, and we will provide a free quote that guarantees the current price for 30 days.

No, these panels are only suitable for use with the Superior WRT3543 fireplaces.
