Determining Minimum Mantel Clearance
when Using a Hood
If minimum clearances in Figure 6 (page 11) are
not met, you must have a hood. When using a hood
there are still certain minimum mantel clearances
required. Follow minimum clearances shown in
Figure 7 when using a hood.
NOTICE: Surface temperatures
of adjacent walls and mantels be-
come hot during operation. Walls
and mantels above the firebox
may become hot to the touch.
If installed properly, these tem-
peratures meet the requirement
of the national product standard.
Follow all minimum clearances
shown in this manual.
NOTICE: If your installation does
not meet the minimum clear-
ances shown, you must do one
of the following:
• operate the logs only with the
flue damper open
• raise the mantel to an accept-
able height
• remove the mantel
FLOOR CLEARANCES
A. If installing appliance on the floor level, you
must maintain the minimum distance of 14"
to combustibles (see Figure 8).
B. If combustible materials are less than 14" to
the fireplace, you must install appliance at
least 5" above the combustible flooring (see
Figure 9).
