A. Installing AK14 Outside Air Kit
This appliance will operate correctly only if adequate ventia-
tion is provided to allow proper draft to the system.
An outside air kit is available as an optional feature with this
appliance. An outside air kit helps to decrease the amount
of room air taken by utilizing outside air for combustion. We
strongly recommend that it be installed.
Note: The outside air kit inlet thimble should be positioned
in a manner that will not allow snow, leaves, etc. to block
the inlet. A 3 ft. (.91 m) minimum height difference must be
maintained from the top of the uppemost chimney section to
the outside combustion air inlet. Reference Section 2.
• The outside air kit can only be installed on the left side of
the appliance.
• Refer to the installation instructions provided with the kit
and Figure 7.3.
