CHASE INSTALLATIONS 
 

Instructions for chase installations are included with the chase 
style termination chosen.  In a multiple chase installation, be 
sure to provide adequate distance between terminations to 
prevent smoke spillage from one termination to another.  We 
suggest that terminations be separated at least 24 inches, 
center to center and stacked at vertical height difference of 18 
inches (see figure 18). 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

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 19). 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

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. 
 

MANTEL 
 

A mantel may be installed if desired (see figure 20), 
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). 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

NOTE: HUD requirements may supersede these minimum 

dimensions. 

 
 

OPERATING GUIDELINES AND MAINTENANCE 

INSTRUCTIONS 

 

GLASS DOORS 
 

Glass doors are standard with the C42MW 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 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 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.
