Not an expert but what i know about fireplaces is that your problem is your fireplace. It is not vented or the vents are clogged not your flues. When your fire is burning it is sucking oxygen from the house and not from outside thru the vents.
Hello one and all, I am wanting to install a flood light on my drive way that is motion activated. However the tricky part is I would like it to have a battery back up but run on house power that only comes on at night. Does anybody know of an existing product or how to wire one from scratch...
