COMBUSTIBLE MANTEL CLEARANCES
Because of the extreme heat this fireplace emits, the mantel clear-
ances are critical. Combustible mantel clearances from top of door frame
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.
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
insert and vent system be installed only in accordance with these
instructions.
