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 clear-
ances shown in Figure 7, when using hood.
NOTICE: Surface temperatures
of adjacent walls and mantels
become hot during operation.
Walls and mantels above the
firebox may become hot to
the touch. If installed properly,
these temperatures 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
