Mantel Clearances for Built-In
Installation
If placing custom mantel above built-in firebox,
you must meet the minimum allowable clearance
between mantel shelf and top of firebox opening
shown in Figure 7. These are the minimum allow-
able 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 the mantel to an acceptable height,
OR
• remove the mantel.
