Manufactured fireplaces often have refractory panels (concrete like) panels that are installed inside the firebox of the fireplace. Refractory panels will limit the heat transfer into the metal sides of the firebox. Large cracks (generally those over ¼”) can cause excessive heat to transfer to the metal shell of the fireplace. This can eventually cause the metal to deteriorate and those cracks in excess of ¼” should be repaired.

Universal Replacement Refractory Panel 23.5' high X 27.5 'wide x 1'(+-) thick If your current fireplace firebrick lining has cracks of 1/4' or more, you should replace the panels for safety reason. These replacement fireplace refractory panels are engineered for extreme heat, have excellent thermal properties, and can be used in prefabricated.
Hairline cracks can appear due to the heating up of the panel causing it to expand and when the refractory panel cools, it contracts and eventually will crack. Cracks can also be caused by excessive heat from an improper burn in the firebox i.e. large volumes of paper or using flammable liquid to light fires.
Panels are also cracked when moving adding or moving large logs in the fireplace. Care should be taken to assure that the logs are not thrown against the panels. Thermal shock from through water on the fire can also cause refractory panels to crack. Proper curing of replacement panels is critical to assure that the panel will last a long time.
Replacement Parts for Marco B41 Series Individual refractory panels are no longer manufactured for Marco fireplaces. Refractory panels must be purchased in kit form which contains a complete set of refractory panels (left side, right side, rear, hearth) or a universal 'cut to fit' panel can be used to replace individual panels.

One can analyze a crack to determine the seriousness by checking the fireplace manual for guidelines regarding nature of the cracks. Using a dime or something of similar thickness, if it can be inserted into the crack consideration should be given to replacing the brick panel. If the brick panel has wide or multiple cracks, it would be wise to replace the brick panel with new panels that are easy to install.
Some cracks can be repaired with castable refractory cement which is easily applied to the crack. That however may not give you the desired appearance. Manufactured replacement panels, available in either vermiculite or brick are the best choice. Vermiculite panels are very easy to cut whereas the refractory type panels require a saw with a masonry blade.

When using this panel for the rear application do not install tightly to the side panels. Allow 1/4' gap for expansion contraction to avoid premature cracking.
It is recommended that the maximum width of any panel not exceed 18 in. For example, if your rear panel dimension is 30 in, it is suggested to divide the rear panel into two pieces 15 in wide (expansion joint). Height of the panel is not restricted in this way.The full installation manual link is below.

Majestic Fireplace Brick Panels
Material Description:
Vermiculite is a naturally occurring non-combustible mineral of the 3-layered silica group. The expanded form of vermiculite is mixed with inorganic binders and pressed into durable refractory boards. There are no fibers or other hazardous materials added. The product is odor free and will not create any off-gases when heated. The boards are strong and durable to 2,012⁰F. Disposal as produced is ecologically “friendly”. Granulated after use, it can be mixed with compost material or as a soil additive for moisture retention, aeration, and beneficial mineral additions.
Applications:
- Original or replacement firebox liner, baffle, insulation for fireplaces, pellet stoves, boilers, and bio-mass heaters.
- Veneer old refractory materials. Suitable for zero clearance fireplaces where the R-Value of the material being replaced is equal to or lower than the R-Value of Thermax Panels.
- Fire protection – such as steel beam cladding, fire door cores, and laminated construction panels and surrounds.
- Heat shield core material.
Better Combustion:
Thermax Boards have considerably lower heat capacity than higher density Refractories, such as fireclay bricks and precast shapes. The heat remains in the combustion chamber and speeds ignition and contributes to complete combustion, lowering emissions and ash volume. The Thermax lined heater remains clean: will not as readily build up with soot and ash.
Vermiculite Refractory Panels are suitable for various domestic heating appliances.
Because of their insulating properties and durability, vermiculite panels play a dual role of heat containment and heat reflection to enhance the desired performance of the appliance. These panels are often used as baffles and burner plates.
Vermiculite panels may be painted with a high temperature coating to create a variety of “looks” and enhance surface hardness. See data for Techno-Coat HT 1100®. The boards may be joined together or to other refractory or steel by screw, clip, or a high temperature adhesive. See data for Techno-Adhesive VL1100®.
Faster fire-up, higher efficiency, and reduced emissions can be achieved by using Thermax Vermiculite panels.

In addition to their utility, aesthetic qualities, and durability, vermiculite panels help our customers achieve “CO2 Neutral” capability in their combustion chambers by increasing combustibility and efficiency to keep emissions to a minimum. In that way, the amount of CO2 given off by combustion is no more than would naturally be given off by decay of the wood or other renewable fuel source.
Vermiculite panels offer the market a “green solution” by contributing to the reduction of emissions, fuel consumption, and the non-hazardous nature of spent linings.
Naturally occurring raw material can be recycled for horticultural use as moisture retaining soil additive.

The recommended density is 600 (37 pcf) for baffles, pellet, and gas fired appliances, 750 (47 pcf) for wood burning applications. Higher density = Higher strength. Caution: Thermax Vermiculite panels are not suitable for all wood-burning applications, for example, the floor of a fireplace. Care must be taken when placing logs into the fireplace so not to impact the panels.
