you must have noncombustible material be-
hind it. Noncombustible material must extend 
at least 8" up. If noncombustible material is 
less than 12",  you must install the  replace 
hood  accessory.  Even  if  noncombustible 
material is more than 12", you may need the 
hood  accessory  to  deect  heat  away  from 
your mantel shelf. See Figures 5, 6 and 7, for 
minimum clearances.
MANTEL CLEARANCES
In addition to meeting noncombustible mate-
rial clearances, you must also meet required 
clearances  between  replace  opening  and 
mantel shelf. If you do not meet the clearances 
listed below, you will need a hood.
Determining Minimum Mantel 
Clearance
If  you  meet  minimum  clearance  between 
mantel shelf and top of replace opening, a 
hood is not required (see Figure 6).
Determining Minimum Mantel 
Clearance When Using a Hood
If minimum clearances in Figure 6 are not met, 
you must have a hood. When using a hood 
there are still certain minimum mantel clear-
ances required. Follow minimum clearances 
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 
ue damper open
• raise the mantel to an accept-
able height
• move the mantel
