 Installing Top Housing

or Termination

Follow the installation instructions provided with the  
chimney termination you have selected.

Installing Chimney In a Chase

Refer to Page 5, Figure 5 for an illustration of a typical 
chase installation.

CAUTION:

  Treatment of firestop spacers and construc-

tion of chase may vary with type of building.  These 
instructions are not a substitute for local building codes. 
You 

must

 check your local building codes to determine 

specific requirements for your city or state. 

NOTe:

  

Other building materials may be required in addition to 
Firestop Spacers.

Finishing

CAUTION:  

All joints between the finished wall and 

the fireplace surround (top/sides) must be sealed with 
noncombustible material to prevent cold air leakage into 
the room. Only noncombustible material may be applied 
to the facing of the fireplace surround.  (Black painted 
area) (Fig. 20)

Finish Wall

Finish the wall with material of your choice.   

Do not 

install a combustible mantel shelf less than 12" (305 
mm) from the top of the fireplace opening for radiant 
models and 12" (305 mm) from top of grille opening 
for circulating models. Do not install a mantel face 
plate less than 6" (159 mm) from top of fireplace 
opening for radiant models and 6" (159 mm) from 
top of grille opening for circulating models.  (Fig. 
22)

 If a combustible material is used below a flat man-

tel shelf, consult your local building codes for minimum 
clearance from top of fireplace opening to bottom of 
mantel shelf.
All joints (top, bottom and sides) where wall or deco-
rative facing material meets fireplace surround must 
be completely sealed with a noncombustible material.  
(Figs. 21 and 22) 

NOTe:

  No side wall protection is required for fireplaces 

installed at 45° to two (2) side walls (corner installation).

Often a decorative surround or vertical portion of the 
mantel is desired. If this is constructed of any combus-
tible material it must be within the safe zone indicated in 
Figure 23.
