Our Answer:

FMI provided a special refractory mortar for setting the firebrick into place. It is necessary to use this mortar, as regular brick mortar can overheat and explode, depending on the material it is made of. Please see page 28 of the manual (can be downloaded on this item's page) for proper installation procedures. FMI no longer sells these units with the brick uninstalled, due to issues with field installation. The panels are now prebricked at the factory and shipped out with the unit.

In Response to Question:

Do you have any specs for the mortar in the firebox? I purchased a 50" Georgian and the installer didn't fill some of the cracks, left the 'gas pipe hole' open and I'm concerned about embers getting behind the bricks or through the hole. I've always thought you should wet bricks before setting them, and that you needed to use fire clay or refractory cement, but the installer used regular mortar mix and it shrank away from the bricks when it dried. Also, the brick pieces under the door mounting frame in front aren't mortared in at all, but they seem to be in your pictures. So, again, do you have any specifications on how the brick lining should be installed?
