I am remodeling an old Shasta travel trailer, and purchased a new Atwood LP/electric 6 gallon water heater. It fits perfectly in the old space, which is directly below the oven. The new water heater has styrofoam insulation, which the old one didn't. That insulation is now within 1/8" or so of the bottom of the oven, won't that melt or burn when I use the oven? What clearance should I have around the bottom of the oven? I can move the water heater about 6" directly lower, but that will require cutting/expanding the cutout in the siding, which I will do if I have to. Or is there a different insulation I can use on the water heater? Thanks for any tips and info!
