gas boiler -- supply and return
Thanks all. I also went ahead and looked at the pump as suggested and the
arrow does show that the circulator is on the return side of the boiler. I
just wanted to be sure.

I am assuming that where the circulator pump is located is the return
water line that goes back into the boiler and the pipe coming out of
the top of the boiler is the supply/hot water line that sends hot
water up to the radiators to supply them with heat.
Is that correct?
