STEP 12 - Assembling the Chimney Sections.
Continue to add chimney sections through the roof opening, maintaining at least a 2" air space.
STEP 13 - Installing Roof Flashing (optional).
If a roof flashing is to be used, install the roof flashing appropriate to the roof pitch and install a TR344 ter- minal cap (round) following the instructions shipped with these accessories.
STEP 14 - Installing an Outside Combustion Air Kit.
The outside air damper assembly is factory installed on the left hand side of the firebox assembly. While its use is optional, it is highly recommended to mini- mize the effects of negative pressure within the structure. Figure 17 illustrates two of many possible methods that can be used to supply outside air to the fireplace system. To complete the outside air system install the AK22 Outside Air Kit according to the installation instructions supplied with the compo- nents.
NOTE: The outside air kit can terminate at any level with the exception that it must terminate at least three feet below the chimney terminal cap as shown in Figure 17.
