combustibles of 9" for H34DF* and a clearance to combustibles of 11"
for HC34DF* , & HL34DF* is required to the underside of any combustible
shelf materials, Figure 3.
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, Figure 4.

The fireplace is supplied with two standoffs. Bend and install these
standoffs on top of the fireplace ensuring that the height of the standoff
maintains a 6" clearance.
