Combustible Wall 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 1" from the rear of
the fireplace to a wall, or any combustible materials, and 11" clearance
from the top of the fireplace to the underside of any combustible shelf
materials.
For Top Vent applications, the minimum clearance is 1" 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.
1” clearance is maintained on sides and bottom of vent runs and 2”
above horizontal vent runs to any combustible material.
† Note: Clearance from top of fireplace to a ceiling within the fireplace
enclosure.
** Note: For mantel clearance, please refer to Section 6: Finishing
To avoid elevated mantel temperatures, all H-Series gas fireplaces
are required to have the supplied standoffs installed. 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
8" clearance.

Installing the Nailing Flange Extension
Once the fireplace is placed into the rough framed opening, the supplied
Nailing Flange Extension must be fasten securely into place, with nails
or wood screws.
Note: The nailing flange extension can be substituted with a
piece of NON-Combustible material of the same size and thermal
characteristics, ie: cement board or equivalent. This is recommended
in applications where the facing materials will not adhere to the
metal nailing flange.
The Supplied nailing extension must be placed along the top edge of
the fireplace and securely fastened in place to the non combustible
header and combustible wood framing.
