Small door in back wall of fireplace

Tags: HVAC

Hi,

I just bought a 45 year old house and am starting to winterize the house. The house has an original wood fireplace which has been converted to gas, there is a chimney with a working flue. In the back wall of the fireplace there is a small sliding metal door. It is about 2 inches tall and 10 inches wide. It is located about 8 inches from the floor. What is this door for? Is is a vent of some kind or it is to deposit ashes from the original wood fireplace? I'm asking because quite a bit of cold air is coming in through the little door and I'm hoping I can seal it up.

Thanks,
Greg

It is a door to access the ash. By opening this, you have access to the unburned junk without having to drag it through your house to dispose of it. There is usually a small fiber rope type gasket you replace on the surface of the door. You may even be able to remove the door and take it to a fireplace outlet and they will install a new seal in it for you. This should help with the draft. Good luck.

typically ash doors are lower on the wall or even on the fireplace floor and are more square than 2x10. i may be wrong but that's been the case for all the ash doors i've seen. Some fireplaces have make-up air vents to provide outside vent/combustion air when burning a wood fire so that the fire doesnt eat up and draw air from the house. this is what that door may be.
