First make sure this is a heater set up for a remote mounted thermostat. If so, the gas valve has 3 screws labeled TH (thermostat) and TP (thermopile) that's the flame sensor with 2 wires coming off it, I don't know where the goofy name comes from. there will be one screw that has both, usually the top one. Wire accordingly. The new valves have a solenoid on the bottom. this connects to the high temp. sensor up top. It has 2 wires on it, one connects to the thermostat wire, the other goes to the screw with TH and TP. Or you can skip it and connect the wire from the back of the valve to the Th and TP screw. Make sure the thermostat wires aren't pinched somewhere, thus eliminating the thermostats control.

Contact Dayton on the internet for this problem. The diagram should be available on their site. Or they will give you a number for customer care. They can give you step-by-step instructions. I am a technician and this is what I would do as their are millions of wiring diagrams. Many are noy up to date.
