D. Frame the Fireplace

Figure 6.4 shows typical framing using combustible materials (2x4 lumber shown).

•Observe all required air space clearances to combustible materials as shown in Figure 6.1 & 6.2.

•Framing across the top of fireplace must be above top standoffs.

2 in. (51 mm) min. air space clearance from chimney.

Note: Framing must be extended straight up, all the way to the ceiling.

 

 

Header MUST NOT be notched!

 

 

 

 

 

 

D = extra space needed for outside air connection.

 

 

 

 

C

 

If outside air duct has no bend, this dimension may be

 

 

 

 

 

reduced as long as minimum clearances are met.
