10 FOOT RULE: 

All flue gas outlet of chimney termination must extend a 
minimum of 3 feet in height above the highest point where it 
passes through the roof and must be at least 2 feet above the 
highest point of the roof that is within a horizontal distance of 
10 feet (see figure 18). 

 
FINISHING THE FIREPLACE: 

Combustible materials, such as wallboard, gypsum board, 
sheet rock, drywall, plywood, etc may make direct contact 
with sides and top periphery of the fireplace face. It is 
important that combustible materials do not overlap the face 
itself. Brick, glass, tile or other non-combustible materials 
may overlap the front face provided they do not obstruct 
essential openings like louvered slots or any other opening. 
When overlapping with a non-combustible facing material use 
only non-combustible mortar or adhesive. 

MANTELS: 

A mantel may be installed if desired (see figure 19). 
Woodwork such as wood trims, mantels, or any other 
combustible material projecting from the front face must not 
be placed within 9 inches of the fireplace opening (and within 
6 inches of the top louver opening). Combustible materials 
above 9 inches and projecting more than 1-1/2 inches from the 
fireplace face must not be placed less than 12 inches from the 
top of the opening of the fireplace (NFPA STD 211, Sec. 7-
3.3.3). 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Mantels or any other combustible materials such as wallboard, 
sheet rock, drywall, plywood, etc. butt up to the side of the 
black metal face of the fireplace.  The clearances from the side 
of the fireplace to any combustible material and wall should 
fall within the limits shown in figure 20.   

 
*Example 1 (figure 20): The face of a mantel, bookshelf, etc. 
is made of combustible materials and protrudes 2-¾” from the 
wall the fireplace is installed in.  This combustible material 
must be a minimum of 4” from the side of the fireplace 
opening. 
*Example 2 (figure 20): The face of a mantel, bookshelf, etc. 
is made of combustible materials and protrudes 11/16” from 
the wall the fireplace is installed in.  This combustible material 
can butt up against the side of the fireplace (i.e. 1” from the 
fireplace opening). 

 
OPERATING GUIDELINES AND MAINTENANCE 
INSTRUCTIONS 
GLASS DOORS 

Glass doors are optional with the fireplace. When the fireplace 
is in operation, doors must be in the FULLY OPEN or 
FULLY CLOSED position only or a fire hazard may be 
created (see figure 21). 
A fireplace equipped with glass doors operates much 
differently than a fireplace with an open front.  A fireplace 
with glass doors has a limited amount of air for combustion.  
Excessive heat within the fireplace can result if too large a fire 
is built or if the combustion air gate is not completely open.  
The following tips should be followed to assure that both the 
fireplace and the glass door retain their beauty and function 
properly.  Both flue damper and the glass doors must be fully 
open before starting the fire. This will provide sufficient 
combustion air and maintain safe temperatures in the firebox.
