10. Attach the indoor combustion air pipe. If using 6" pipes, attach the single-wall
combustion air pipe run to the collar on the concentric adapter box with sheetmetal
screws. If using 7” pipe on Sizes 200-400, install a taper type enlarger as illustrated In
FIGURE 9B, page 13.
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 require-
ments, pages 9-13, and illustrated in FIGURE 12.

for Vertical Vent/

Option CC2
1. Determine the location of the vent terminal.
Select a location away from fresh air intakes, allowing space for the concentric adapter
box inside. Vent terminal must be located from adjacent buildings as shown in
FIGURE
18, page 20.
If more than one vertical concentric vent/combustion air terminal (Option CC2) is being
installed, the minimum spacing between vent centerlines is determined by the mini-
mum outdoor design temperature (most extreme outdoor condition at the site).

2. Install the Vent Pipe and Combustion Air Pipe Run - Use the type of pipe speci-
fied (Requirement No. 1, pages 9-10), and comply with the attachment requirements in
Requirement No. 2, page 10. Length must comply with Requirement No. 3, page 10.
Seal all joints. Due to the high temperature,
do not enclose the exhaust pipe or place
pipe closer than 6" (152 mm) to combustible material. Provide supports for the pipes.
Extend the runs to close to the roof at the location selected in Step 1 above.
WARNING
All vent terminals must be positioned or located away from fresh air
intakes, doors and windows to preclude combustion products from
entering occupied space. Failure to comply could result in severe
personal injury or death and/or property damage.
