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.

Installing The Standoffs
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.

Removing the Nailing Flange Extension
The 4" nailing flange extension is shipped attached to the top edge of
the fireplace, see Figure 1.
The nailing flange extension may be substituted with a piece of
NON-Combustible material of the same thermal characteristics, ie:
cement board or equivalent to fit the opening. This is recommended
in applications where the facing materials will not adhere to the metal
nailing flange. To remove the Nailing Flange Extension follow the
directions below:
STEP 1: Remove screws from top of the unit
STEP 2: Remove shell from the top of unit. Remove screws from
outer edge.
STEP 3: Remove shell from the top of unit. Remove screws from
outer edge.
STEP 4: Remove the nailing flange extension from the unit.
Reinstall shell. Screw shell in place.
