Installation Instructions for Vertical Vent/Combustion Air Kit Option CC2
1. Determine the Location of the Vent Terminal(s). - Select a location away
from fresh air intakes, allowing space for each concentric adapter box inside. Vent
terminals must be located from adjacent buildings as shown in FIGURE 24, page 25.
A vent terminal is required for each furnace section. When more than one vertical
concentric vent/combustion air terminal (Option CC2) is being installed, the minimum
spacing between vent centerlines is determined by the minimum outdoor design
temperature (most extreme outdoor condition at the installation site).
2. Install the Vent Pipe and Combustion Air Pipe Run(s). - Use the type of
pipe specified (Requirement No. 2, page 15), and comply with the attachment
requirements in Requirement No. 3, page 15. Length must comply with Requirement
No. 4, pages 15-16.
Seal all joints. Due to the high temperature, do not enclose the exhaust pipes or
place pipes closer than 6" (152 mm) to combustible material. Provide supports for the
pipes. Extend the runs to close to the roof at the location(s) selected in Step 1 above.

3. Prepare hole(s) through the roof for the 8" (203mm) diameter combustion air
pipe. - A thimble may or may not be required depending on building construction and/
or local codes. The larger diameter combustion air pipe serves as clearance for the
vent pipe on non-combustible construction.
4. Prepare the Concentric Adapter Box
a) Attach the brackets to the box. Follow the instructions in FIGURE 20.
b) Attach the outside portion of the combustion air pipe to the box. Determine
the length of the combustion air pipe so that dimension ”X” in FIGURE 21 is equal to
the bracket length, plus the roof thickness, plus anticipated snow depth, but does not
exceed 48“ (1219mm) or have less than 18” (457mm) of pipe above the roof. Attach
the inlet air pipe to the collar of the concentric adapter box with sheetmetal screws.

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.
