9) Seal the vent pipe. Verify that the double-wall section of vent pipe has a slight
downward drop (1/4" per foot/6mm per 305mm) toward the vent terminal end. Use
silicone sealant and seal the circumference of the pipe and the opening of the box.
Seal the area around the pipe completely.
10) Attach the indoor combustion air pipe. On Sizes 150 and 200, install a taper-
type enlarger as illustrated in FIGURE 4A, page 11. On Sizes 250, 300, 350, and
400, attach the single-wall combustion air pipe run to the collar on the concentric
adapter box with sheetmetal screws. Seal joints with tape or sealant.
Installation of the horizontal vent and combustion air system on your separated com-
bustion unit is complete. Verify compliance with all venting installation requirements,
pages 9-13, and FIGURE 8.
