thermostat didn't come with wire diagram. The 3500 PPW doesn't have a common wire. The thermostat has common terminal. Also which terminal is for the power indicator light?
GD8MAN for Model Number 3500 PPW
Answer Gd8, The wiring to the new thermostat should be : Double Black wires from infinite switches should be on terminal no.1 or L1. Double Black wires from the "ON" light and jumps to no.4 terminal should be on the H terminal. Blue wire to Broil element should attach to BR. And and Yellow wire to the Bake element shoul be on the BK terminal. Thats based on the wiring diagram for the model number you supplied. Thanks and Good Luck
