In Maxim using sum has no negative effect since it keeps the image buffers in floating point (32bit). It will ask if you want to stretch the image before saving it into a 16 or 8 bit file format, FITS can handle 32 bit natively of course. However using sum/avg to stack images is usually a last resort course of action in any case!
