Clearances
Unless otherwise stated the clearances listed below are Minimum
distances to combustible materials. Please Note: A major cause
of chimney related fires is due to a failure to maintain required
clearances (air space) to combustible materials. It is of the greatest
importance that this fireplace and vent system be installed only in
accordance with these instructions.
Combustible Mantels
Because of the extreme heat this fireplace 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: 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.
