backwall.

of the floor panel as well. |
 |
|
Prefab firebox with
refractories removed.
Note the heat scorch marks
on the metal sides and floor. The box is not warped, and
fortunately in this case the marks do not represent any issues. |
 |
|
These are the sidewalls and
backwall that were removed from the firebox. |
 |
|
The panels shown here are
roughly ¾" to 1" thick. |
 |
|
Firebox with new backwall
and floor panel installed. The floor panel is roughly 1½" thick. |
 |
|
This is the firebox with all
new refractory panels. |
 |
|
| |
|
| |
After the new panels are installed, the fireplace cannot be used for 24
hours so that they can reach room temperature.
Then, you must have at least 6
small kindling fires in order to cure (harden) the new panels, or they will
crack prematurely. |
| |
|
| |
Recommended replacement of the panels is if the cracks are the thickness of
a nickel or more. These panels were not only cracked, but also the outer
material was separating and coming off.
Many of the manufacturers will
no longer sell just the individual panels, and now require you to buy the
entire set of panels--even if only one panel is cracked.
Only use parts that have been
provided by or approved by the manufacturer. Generic refractories that
need to be cut to the proper size will not carry a listing from your
fireplace manufacturer and will likely cause you to assume all liability of
any problem develops. |
