I have a fireplace insert (Harman) with a metal panel surround. When not in use I get the typical odors throughout the house. I would love to install a top sealing damper, but due to the metal panels I do not have access to the interior of the fireplace. I tried to find top sealing dampers that are remotely controlled without luck. Any suggestions?
 
Welcome to the forums!

Does your insert vent into a 6" liner, connected at the stove, the extends to the top of the chimney? Or does it vent into a length of pipe that extends only above the smoke shelf ( a "direct-connect') or just vent right into the chimney from the stove, with no pipe (a "slammer")?

With a liner system, if you install a block-off plate, you shouldn't be experiencing odors. The will also provide the best system to ensure good draft and prevent heat loss, let alone to maximize safety and a clean chimney.

Personally, I would NEVER install a top-sealing damper in your situation, for risk of letting CO build up in the house when there are still any trace of live coals in the stove. A little dab will do ya in.
 
The metal surround panels are removable.

Is this the only fireplace in the house?
 
It is a slam in. The panels are removable yes, but not a permanent solution unless I'm not understanding you (which is very possible). How would I mount the chain to pull the damper closed? It's the only fireplace. Tile lined flue that is in good shape.
 
You need a liner whether it is for coal or wood it is dangerous to burn either the way you have it setup now

This type of install is no longer permitted. Put a full liner on the stove and not only will it perform better, but it will eliminate the issue completely. In the meantime be sure you have good, working CO detectors.
 
Mellow, the metal surrounds would prevent the arm coming out from the fireplace-my stove looks similar to your avatar. It's a coal burner that I burn wood in. Spoke with Harman back when I bought it (15 years ago) and the setup was fine with them. Tile is the liner, but I am not going to argue the point (it wasn't even made for a liner, you have to find an adaptor for it. I never have a problem burning, it's just on wet cool days that I don't burn I get the odor from the down draft. CO monitors have never gone off. It's not a primary heat source, just keeps the lower section of my spit entry warm.
 
And you wont have a problem till you do. And with those when there is a problem it is a big one. It is no longer to code and is absolutely unsafe which is why i will no longer even work on one if i get called out to clean one. I have put liners on many of them i just fab up a boot and go with it. You are going to do what you want but you will get very little support here for that install. And i have talked to harman many times and i am positive they do not condone an install that is not to code and they also are probably not ok with burning wood in a coal stove. Unless it is a combo unit which i have never seen in an insert but that doesnt mean they didnt make them
 
Harman told me directly that the only reason they cannot classify it as a woodburner was EPA Regulations

Ok so it is probably a combo unit then that is the way that all of their wood coal units are now. Like i said the only inserts i have dealt with from them were pure coal the only air came in under the grates which works terribly for wood. But i am not surprised they made a combo
