Short answer
The law
430 ILCS 135/10(a): every dwelling unit shall be equipped with at least one approved carbon monoxide alarm in operating condition within 15 feet of every room used for sleeping purposes; the alarm may be combined with a smoke detector if the combined unit meets both standards. 10(b) applies the same to structures with more than one dwelling unit. The Act also assigns testing and battery duties between owners and tenants (430 ILCS 135/10).
Why with gas appliances
Nicor Gas: carbon monoxide comes from incomplete combustion of fuels including natural gas and propane, and can cause illness and death when not properly vented; if symptoms are suspected, get everyone and pets out to fresh air and call for help (Nicor Gas).
