Installing the Chimney System
Start by attaching the first chimney section to the collar
on top of the fireplace.
Install the pipe as pictured in Figure 16. When you
get a good lock, you will hear the pipe clearly snap
together. Once sections are snap-locked in place, it is
extremely difficult to get them apart. Make sure the
pipe is firmly snapped and locked together as each
pipe section is mounted.
When installing elbows, only outer pipe will snap- lock.
Middle pipes simply slide into position. Be sure to
always attach straps on upper elbow to a structural
framing member. (Fig. 17)
Continue installing the pipe as required until pipe is
installed up through the ceiling. At this point, you must
install a firestop spacer.

4. Attach the inlet collar with four (4) #10 screws to the
side near the bottom of the fireplace. Slide the duct
over the collar and attach the duct to the collar using
the plastic tie straps or three (3) screws (screws not
provided). Continue attaching the ducting together
using three (3) screws at each joint until you have
installed sufficient duct to arrive at your duct termina-
tion location.
5. At the termination end, install the duct termination.
This should be installed from the outside of the
home. Cut a hole in the desired location approxi-
mately 4¹⁄₂” in (114 mm) diameter, caulk around the
hole, and slide the termination through the opening
from outside the home. The termination/rain cap
should be caulked around its perimeter to assure a
tight seal. The rain cap opening should be positioned
downward. (Fig. 15)
The AK-MST Outside Air Kit is now installed and ready
for use.
