Should I turn off the pilot on a wall heater in the summer?

Well, I called an appliance repair guy and he is coming to put a valve on my gas line that I can turn on and off as needed. My pilot lights keep the kitchen hot and I use my stove/oven maybe three times a year. So he will be putting a handle on my gas line so that I can turn it off and on when I actually use it.

This is an old codger with 40+ years of experience (semi-retired) so I would think that he would know if that wasn't safe to do.
