a size smaller than the 3/4” long sheetmetal screw, with the elbow pointing down,
drill a pilot hole through the top center of the elbow socket and the vent pipe.
Remove the elbow. In the elbow only, enlarge the drilled hole to 7/32”. The elbow
will be attached from the outside in Step 8b).
With the pipe turned so that the drilled hole is at the top, slide the end of the vent
pipe out through the box and the combustion air pipe. Position the vent pipe so
that it will extend between 3” (76mm) and 6” (152mm) past the end of the com-
bustion air pipe. Adjust the pipe so that the screw hole is in the top center. Verify
that the silicone sealing ring on the box is properly seated. Do not add sealant
to the ring.
Join the “terminal end” vent pipe to the vent pipe run. Re-check the silicone ring
to be sure that it is still properly seated.
7. Attach the indoor portion of the combustion air pipe. Use sheetmetal
screws to attach the single-wall combustion air pipe run to the collar on the con-
centric adapter box. Seal with tape or sealant.
8. On the outside, install the inlet air guard spacers, attach the elbow,
install the bird screen, and seal or ash around the combustion air pipe.
8a) Remove the screws holding the inlet air guard (installed in Step 4c). Slide the
spacers onto the ends of the four spokes that support the vent pipe. Re-attach
the guard.
8b) Slide the elbow over the end of the vent pipe and attach it with the eld-
provided 3/4” long sheetmetal screw. Slide the bird screen into the socket on the
open end of the elbow. The elbow must be pointing down.
8c) Seal around the combustion air pipe with an outdoor caulking material or
a masonry cement or a combination of ashing and caulking. Adjust the seal-
ant and the pipe so that the metal pipe will have a slight downward slope to the
outside. The downward slope and the 1/2” drain hole (Step 4b) will prevent rain
water from running through the pipe into the concentric adapter box.
Installation of the horizontal vent and combustion air system on your separated-
combustion unit is complete. Verify compliance with all venting installation
requirements, pages 13-18, and FIGURE 16.
