Don't often venture into the Home and Gardens areas so forgive the Noobie question.
Have a couple of rooms with gas fires in them. There are vents in the walls which allow a gale to blow through them. Upon inspection the only thing seperating the inside of the house from the outside in these vents is a plastic grill. Not ideal.
I remember seeing some sort of air vent on one of those property shows which allow the free flow of air to prevent Carbon Monoxide issues but effectively blocks the vent to drafts.
Does anyone know of this mystery device?
