Clearances

Unless otherwise stated the clearances listed below are Minimum 
distances to combustible materials.  

Please Note: A major cause 

of chimney related fi res is due to a failure to maintain required 
clearances (air space) to combustible materials. It is of the greatest 
importance that this fi replace and vent system be installed only in 
accordance with these instructions.

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:  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.
