I am replacing the siding on my home and would like to install cadet wall heaters while I have the wall open, my question is how should I insulate around the heater? can the insulation be touching the heater pan? or does the pan get to hot for insulation to be installed around it?
Assuming you are using Fiberglass with metallic foil, don't see a problem. Not familiar with you heater brand, but if designed right, the heat projects outward and does not heat the enclosure very much.
