Patrik, your main focus will be on the exhaust system to maintain acceptable CO levels. Please reference Table 6-4, which requires an exhaust rate of 0.75 cfm/sf, unless there is a certain openness factor to the outdoors. Local codes may require different rates.

Thank you Roger. Could I operate the fan system intermittently with the CO sensor OR an occupancy sensor; or do i have to run the fans continuously? If using the CO sensor, what would be the right threshold (ppm)? thank you!

Patrik, operation really depends on the applicable code. 15 ppm is the recommended maximum limit for CO.
