Optional Firebrick Panels

To ensure the longevity of your fireplace all of our Mason-Lite units require a firebrick liner. The firebrick panels add a classic look to your fireplace and efficiently reflect more heat into your living space. A typical firebrick lining takes a Mason five to eight hours of labor to install but the Mason-Lite prefabricated firebrick panels install easily in a matter of minutes.

The optional prefabricated firebrick panels are available in full running bond, split running bond, and a split herringbone. These prefabricated panels are lightweight, durable panels that are installed on site. Unlike others faux brick panels, Mason-Lite panels are made with real firebrick. The set consists of two sides, a back and a bottom that fit the standard firebox sizes of 33″-63″.

Chimney Design

The Mason-Lite fireplace construction has been tested with both a masonry chimney, manufactured by MFI, and a Class A listed metal chimney. Either chimney system will work.

When installed, the maximum overall height of the Mason-Lite fireplace design is 40 feet. The minimum chimney installation height is 14 feet, given that the chimney is straight. If the chimney is not straight, the minimum installation height is 17 feet.

Ask a Question
  • Does the 44" come with the firebrick insert shown in the 3rd picture above? it isnt mentioned whether it comes with it or not?

    The brick liner is not included

  • Does the price include all key pieces mentioned to build the modular fireplace such as hearth, wall, lintels. steel support, rating plates, all thread bars and rebars? Or we have to pay for each of these ( meaning, the price will only include firebox, 2 ft masonry chimney and a bag of mortar?)

    Yes, those key parts are included. You may check out the Mason-Lite User Manual (pgs. 3-7) to see the full list of parts that are included and which ones are not included but can be purchased in your local hardware store.
