Why are un-vented gas appliances not allowed?
A. Unvented gas appliances are not allowed due to potential carbon monoxide risks. Nationally recognized fire codes do not allow these appliances to be located in a childcare setting. It should be noted that manufacturer’s guidelines instruct the owner to keep a window open during the use of these appliances.
