Furnace covers / patches - How did you do it?

[robwok]

I replaced my Bowen water heater and I kept the original cover on my 64 overlander. (Still in progress, but I was able to get a 10 gallon tank in there finally - I want to post pics when I'm done)

I need to do something similar to the furnace. I am having trouble finding furnace mods by folks to keep them original. Can anyone help provide links? The PO used silicone to seal it, so I'm going to have to do some work to patch the original hole. I already ordered a sheet of Allclad.

Here is what I did

Are you putting in a new furnace and just want the exterior to look the same? I took my old furnace out, did not replace it, and used the original exterior exhaust shroud with a piece of waffle-aluminum underneath it to seal the hole. Can you post a pic of your situation?

Tphan, I actually have the situation based on the link just above yours by HiHo. Same ugly double rivet situation, but much older setup for the heater. I'm torn between reinstalling the furnace and getting a top mounted heat pump. The problem is that with a heatpump, I wouldn't have heat when boondocking, and when docked, wouldn't have heat once it gets really cold unless I get the electric strip.

My trailer has a waffle shroud that went over the furnace exhaust. I think I can still use that but moved over. My main concern was how to do the patch. I kind of like the trim tht HiHo used, but really wanted it to look as original as possible.
