Matherly Insert Removed in 1950s home. How can vent above it be removed?

[BH-1]

I am brand new to wood stove inserts and fireplaces, in general.

I removed this Matherly Heat Saver wood stove insert from a home built in the 1950s. There is a grill with a vent above the fireplace where the insert used to be. It seems but I can't tell for sure, that the vent is part of the metal firebox and the whole thing got bricked in after it was installed. There is also a light switch to the left of the hearth that turns on fan or a blower.

1. How can I remove the interior vent over the fireplace? I'd like to put a mantel in and may just leave it as a fireplace without a new insert. I'm comfortable removing brick but am not with disassembling something connnected to the metal firebox. If I have to hire someone, I'm not assuming they will know what to do since it's an older installation.
2. Can I reduce the hearth width? I'd like to make it closer in size to the actual fireplace. It runs across 3/4 of the wall. There are slatted vents in the hearth on either side of the fireplace.

Thanks for any insights and guidance!

I'm not familiar with this brand, but it looks like it is a heatform-style fireplace, not an insert. One option is to install an actual insert into this fireplace. This would require cutting a couple of the center heat tubes. The hearth width may be reduced a bit, depending on the fireplace width.

Note that there are clearance requirements for a mantel that is combustible. These to not apply to non-combustible mantels.

Thank you for your response, Thank you too for the link and reminder re: mantles/combustible material.

Here's a picture of the woodstove insert that was there.

I found a video on Youtube with someone demo-ing a woodstove insert with the vents above. He was pulling the entire brick face off. It revealed a firebox and the vents that were integral to each other. Removing the firebox/upper vents is likely beyond my skill set. I don't want to solve one problem and create a bigger, expensive one!

That old timer insert was probably installed as a slammer with no stainless line flue connection . It also violated the hearth extention requirement of 16" in front of the stove doors. A modern insert installation is quite an improvement over this and safer. The modern insert connects to a 6" insulated liner. It looks like the center tube would need to be cut out so that the liner clears. This can be done with a sawzall or angle-cutoff tool.

You cannot just cover those vents and have a functional fireplace.

Thank you. I have a sawzall!

Thank you. I have a sawzall!

What ever happened??.

@Dd1001 I left it untouched for now while I'm working on the kitchen cabinets. (I wish I had a diagram of the whole system behind the brick!) About a month ago, a general contractor who was giving me an estimate on something else said the blower above the fireplace makes a big positive difference in heat. They suggested I leave it. But I better get a move on whatever I do if I want to use it this fall.

Is the insert installed with a full stainless liner from the stove outlet the top of the chimney?
