Combustible Mantels

Because of the extreme heat this fi replace emits, the mantel
clearances are critical. Combustible mantel clearances from top of
the louvers are shown in the diagram below. Mantel may be installed
anywhere in the shaded area or higher.
NOTE: Mantel clearances for Installation into a Zero Clearance Kit
are different. Please refer to the Zero Clearance Kit Manual
for details.
Note: A non-combustible mantel may be installed at a lower
height.
Note: Ensure the paint that is used on the mantel and the facing
is "heat resistant" or the paint may discolour.
