What carbon monoxide detector installation involves

Carbon monoxide is odorless and invisible. It comes from fuel-burning appliances such as gas furnaces, boilers, water heaters and ranges, from vehicles in attached garages, and from generators run too close to a home.

Most states and many cities require CO alarms in homes with fuel-burning appliances or attached garages, and hardwired, interconnected alarms are typically required during renovations. Combination smoke and CO alarms can cover both needs in one device.
