In preparation for my unit installation, I'm learning how to make a block-off plate myself (huge thank you to this community for so many helpful posts!), coz installer keeps saying it's overkill.
Step 5 from the instructions for the Block-off plate construction (thank you again!) says:
I'm making the plate myself in advance and should have everything ready for the installer, so I want to make a bigger hole as suggested - just in case we have to move that oval adapter during installation.
Question: when the liner is aligned correctly, how to attach that larger patch piece to the block-off plate, which is already in place? I won't be able to hold a nut on the other side...
Just in case: this is how the oval-to-round adapter will be routed (green lines) and where the plate will be situated (blue line). I have already cut a cardboard:
Thank you.
Step 5 from the instructions for the Block-off plate construction (thank you again!) says:
If the liner is coming into the firebox at an angle or you are concerned about fitting, you can cut a bit larger rectangular hole in the block-off plate, then cut a larger patch piece that has the hole for the liner. This will provide some adjustment room to get the liner aligned correctly with the stove. (C alternate)
