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 1" from the
rear of the fireplace to a wall, or any combustible materials, and 17

Installing The Standoffs
To avoid elevated mantel temperatures, all H*42DF* 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 6" clearance.

Installing the Nailing Flange Extension
Once the fireplace is placed into the rough framed opening, the
supplied Nailing Flange (Part No. H42074) must be fasten securely
into place, with nails or wood screws. as shown in Figure 7.
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.
