P52DF* Indoor Gas Fireplace

Clearances:

When installing a shelf over the top of the fireplaces, the
following guidelines must be adhered to:
For Rear Vent multi-elbow applications, the minimum
clearance is 1" from the elbow off the rear of the fireplace to
a wall, or any combustible materials, and 12" 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 26" 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.

NOTES:
† Clearance from top of fireplace to a ceiling within the
fireplace enclosure.
†† 2 1/2" clearance is from the main body of the firebox, NOT
the insulated flange. Clearance to the insulated flange is 1".
Installing The Standoffs
To avoid elevated mantel temperatures, all P52DF* 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 7 ½" clearance.
