Clearances; Installing The Standoffs - Montigo H38DF PRC Installation & Maintenance Manual

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.
H*38PR* 11" 17 1/2"
† Note: Clearance from top of fireplace to a combustible ceiling within
the fireplace enclosure.

Installing The Standoffs

To avoid elevated mantel temperatures, all H*38PR* 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.

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:
