Mantel clearances for Built-In
Installation
If placing custom mantel above built-in fire-
box, you must meet the minimum allowable
clearance between mantel shelf and top of
firebox opening shown in Figure 7. These are
the minimum allowable mantel clearances
for a safe installation. Use larger clearances
wherever possible to minimize the heating of
objects and materials placed on the mantel.
cAutIoN: close screens
before operation of vent-free
gas log heater. do not allow the
heater to touch or extend beyond
the fireplace screen.
If your installation does not meet the minimum
clearances in Figure 7, you must:
• raise mantel to an acceptable height,
OR
• remove mantel.
Note:
All vertical measurements
are from top of fireplace
opening to bottom of mantel
shelf. All measurements
are in inches.
Facing material (above
firebox) may be of
combustible material,
including decorative
mantel ornaments.
