Just installed day and night furance I can't get the burner to fire

You will need to check the circuits with a meter. The t-stat should read zero between "R" and "W", if not it is not calling for heat. The gas valve should have 24-30 volts to call for heat, if not your t-stat is not working. You need to get a good meter and learn how to use it. DrTom4444
