Figure 5 shows a typical framing (using 2 x 4 lumber) of the fireplace, assuming combustible materials are used. All
required clearances to combustibles around the fireplace must be adhered to. Any framing across the top of the
fireplace must be above the level of the top standoffs.
Chimney sections at any level require a 2 minimum air
space clearance between the framing and chimney section.
3. Sidewalls/Surrounds
Adjacent combustible side walls must be located a minimum of 24 from the fireplace opening. See Figure 6. If you
are using a decorative surround constructed of combustible material, it must be located within the shaded area
defined in Figure 6. Short stub walls are also acceptable if they are contained within the shaded area.
CLEARANCES!
A minimum ¾ air clearance
must be maintained at the back
and sides of the fireplace as-
sembly except at the nailing
flange where the clearance is
½.
Chimney sections at any level
require a 2 minimum air space
clearance between the framing
and chimney section.
