D. Wall and Mantel Temperatures
Combustible Mantel and Surfaces around a Fireplace
The allowable temperature rise above ambient is 117 °F
(47 °C) for all exposed combustible surfaces around the
fireplace, including the mantel, when installed according
to the installation instructions. Non-combustible surfaces
and mantels do not have a maximum temperature limit;
however the installation instructions must still be followed
for any restrictions on placement of non-combustible
materials on or around the fireplace.
Example: The mantel above a fireplace in a room that
is 70 °F (21 °C) is allowed to reach but not exceed
187°F (86 °C) (70 °F (21 °C) +117 °F (47 °C) = 187°F).
