Hello I am working on an all electric project with no combustion appliances. Do they need to install CO meters in every unit? The credit states "Do not install any unvented combustion appliances (ovens and ranges excluded). Install a carbon monoxide (CO) monitor on each floor, hard-wired with a battery backup. In multifamily buildings, install a CO monitor on each floor of each unit." which does not mention what do in the case where no combustion equipment is installed- I would assume no, as electric appliances will never create carbon Monoxide.
Thank you!
