I am installing a King Brand PAW model 240 volt forced air heater in my bathroom. King manual only requires 6inch from adjacent wall. See attached link-

I am installing on dedicated 20amp 240 volt dedicated circuit with switch on other side of shower.
Does NEC say anything regarding heater distance from shower door?
Thanks.
