Yes. Carbon Monoxide (CO) is an extremely poisonous gas that can be present in the fumes from the incomplete combustion of fuels.
Although Carbon Monoxide (CO) is an issue more associated with gas appliances it can be the result of combustion of ANY fuel, including wood.
The gas cannot be seen, smelled or tasted making it difficult to detect. You must fit an audible CO alarm but you also need to have your appliance regularly serviced and cleaned, and your chimney swept.
