Welcome to the forums.

A picture is a must ! ....... How-to-insert-pictures.

What's the model of the old thermostat ?
What nest are you putting in there ?
A nest may not be the best choice with a dual fuel system.
Your old stat is using a sensor to control dual fuel activity.... the nest won't have that.
