Clearances - Montigo H38DF-CLCR 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 13" 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
on page 21.
Installing The Standoffs
To avoid elevated mantel temperatures, all H*38C* 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 as shown in Figure 6, ensuring that the height of the
standoff maintains a 4" clearance from the top of the unit to the 1st
combustible stud.

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:
Figure 7� Remove screws from top of the unit
Figure 7a� Remove shell and insulation from the top of unit. Remove screws
from outer edge.
Figure 7b� Remove the nailing flange extension from the unit. Reinstall shell
and insulation. Screw shell in place.
