MANTELS 
 

A mantel may be installed if desired (see figure 18 & 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 must not be placed less than 12 inches from the top 
opening of the fireplace (NFPA STD 211, Sec. 7-3.3.3). 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 

 
 
 
 
 
 
 
 
 

OPERATING GUIDELINES AND MAINTENANCE 

INSTRUCTIONS 

GLASS DOORS 

Glass doors are optional with the fireplace.  When the 
fireplace is in operation, doors must in FULLY OPENED or 
FULLY CLOSED position only or a fire hazard may be 
created (see figure 20). 
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 the flue damper and the glass doors must be 
fully opened before starting the fire.  This will provide 
sufficient combustion air and maintain safe temperatures in 
the firebox. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

 
IMPORTANT:

 The glass must be allowed to warm slowly 

and evenly.  The tempered glass will withstand a gradual 
temperature rise to 550 degrees Fahrenheit, which is more 
than a normal fire will generate.  Such materials as pitch/wax 
laden logs, very dry mill end lumber, and large amounts of 
paper or cardboard boxes can create an excessively hot fire 
and should not be burned in this fireplace.  Always keep the 
fire well back from the doors and never allow flames to 
contact the glass. 
 
 
 
 
 
 
 

 
CLEANING THE GLASS 

 
Clean the glass with any commercial glass cleaner or soap and 
water.  Do not use any abrasive material to clean the glass.  Do 
not clean the glass with any cool water if the glass is still hot 
from the fire and smoke. 

Figure 20               GLASS DOORS 

WARNING

: Fireplaces equipped with glass doors

should be operated only with doors fully opened or doors
fully closed.  Doors, if left partly open, may draw gas and
flame out of the fireplace opening creating risks of both
fire and smoke.
