Install Remainder of Chimney Sections

Since you have already preplanned the height of your 

termination according to the 

Ten Foot Rule

, continue to 

install pipe to the predetermined height.
Check the chimney top installation instructions for 

details on how high above the roof top the chimney sec-

tions (all pipes) should extend.

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 irestop 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 

speciic requirements for your city or state. 

NOTe:

  

Other building materials may be required in addition to 

Firestop Spacers.

Finishing

CAUTION:  

All joints between the inished wall and 

the ireplace 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 ireplace 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" 

(305mm) from the top of the ireplace opening for 

radiant models and 12" (305mm) from top of grille 

opening for circulating models. Do not install a 

mantel face plate less than 6" (159mm) from top 

of ireplace opening for radiant models and 6" 

(159mm) from top of grille opening for circulating 

models. 

(Fig. 22)

  

If a combustible material is used be-

low a lat mantel shelf, consult your local building codes 

for minimum clearance from top of ireplace opening to 

bottom of mantel shelf.
All joints (top, bottom and sides) where wall or deco-

rative facing material meets ireplace surround must 

be completely sealed with a noncombustible material.  

(Figures 21 and 22) 

NOTe:

  No side wall protection is required for ireplaces 

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