Clearances
When installing a shelf over the top of the fireplaces, the following
guidelines must be adhered to:
For Rear Vent applications, the minimum clearance is 2" from the rear
of the fireplace to a wall, or any combustible materials, and 9" clearance
from the top of the fireplace to the underside of any combustible shelf
materials.
For Top Vent applications, the minimum clearance is 2" from the rear of
the fireplace to a wall, or any combustible materials, and 17 1/2" to the
underside of any combustible shelf materials.
(Minimum 2" clearance must still be maintained around the vent
pipes.)

fireplace, framing depth 20 1/8" may be
reduced by 5/8".
