I’m installing a Lopi LX in my heatform fireplace. I cut out the tubes and a notch for the 8” pipe but after test fitting the insert I’d like to move it back further.

Can I cut out the back of my heatform and push the stove closer back to the inner steel wall? Fireplace is masonry.

From I can see after plasma cutting the hole for the liner is that it’s mortar and then brick which is the finish on the outside.

I am considering cutting the inside (1/4” steel part) of the heatform out just wide enough to clear the stove. Then either leave just the inside 1/16” steel remaining on the outside of the heatform or weld angle iron onto the inside piece and reattach it inside the hearth.

My biggest concern as it should be is making sure it’s safe.

If the other side of that brick is outside you are fine you may want to add some insulation though

I cut the back out of the heatform and then went ahead and removed the steel inner wall because it was so rusted and deteriorated not much of it was left. For anyone considering this I posted some pictures.

I would feel odd using a plasma cutter in the living room! Looks good.

You don't want that silicone there temps will be to high and it will stink. I can't tell but it looks like that joint may be backwards as well.
