Last night,I put some copper flashing material(HD) between the frig box and
ammonia tubing.For a heat shield. I removed the little sheet metal screws
that attach the metal backing on the rear of the frig, and tucked the
flashing inbetween the box and rear cover. Then I siliconed this gap and
put the screws back in.Dont want heat getting between them, and into the
foam insulation.I am going to fire it up by gas grill tank tonight and
check it all out. Installation in the van  is soon.
