Homeowners insurance can be voided in several scenarios. That can include making too many claims in a short period of time, leaving a home vacant for an extended period of time, renting out a home or room illegally, using a home as a business illegally, and any kind of criminal activity connected to the home.

No, but they both serve distinct life-saving purposes. Smoke detectors primarily sense the presence of smoke, typically caused by a fire, and emit loud alarms to alert occupants to evacuate. In contrast, carbon monoxide detectors monitor the levels of carbon monoxide gas, an odorless and colorless but deadly substance produced by incomplete combustion of fuels. When CO levels become dangerous, CO detectors sound alarms to warn inhabitants of potential poisoning risks. 

No. Removing the cause of concern will only lead to deeper concern. You cannot use any fire-powered appliance like a fireplace or furnace without an escape route for the smoke and fumes. If you remove the flue intending to repair or replace it, you should only use the fireplace, wood stove, or furnace once the flue is in working order. If you cannot replace the flue you have removed, call a chimney repair professional immediately.

The primary disadvantage of a ventless fireplace is that it doesn’t have an exterior venting system. This means that the byproducts from combustion are emitted into your home, which raises some safety concerns. In addition, ventless gas fireplaces produce moisture as they burn—and if there’s no ventilation, you could end up with a mold problem.
