5.1.4 Finishing Recommendations
NOTE: The surface area above the appliance may be affected
by high temperatures emitted from this appliance. To help
avoid or reduce the possibility of the sheetrock to crack, Hus-
song Mfg. recommends the following methods:
•
Ensure the non-combustible material and sheetrock is dry
and dust free.
•
For taping and mudding seams, we recommend heat resili-
ent tape, mesh and joint compounds, such as Durabond.
Mud must be cured as per manufacturers recommenda-
tions.
•
For a painted surface, use a high quality acrylic latex pri-
mer and finish coat. Avoid flat or light-colored paints to
prevent discoloring.
Disclaimer: Kozy Heat does not guarantee any materials used
around the fireplace. Kozy Heat disclaims any and all liability
for any damage to finishing materials including warping, discol-
oring, cracking, peeling or flaking. This also includes any off-
gassing or unpleasant smells from materials when they are
heated.
