Greetings;

I replaced the old Robertshaw Unitrol 7000 BER-1 24 volt gas valve with a White Rogers 36C03-333 and the relay terminals are different. The furnace wiring diagram is nowhere to be found. Can't seem to figure out how to connect the 2 black and 2 tan/white leads to the new valve.

Obviously, any help would be appreciated. I can post pics if needed.

Sorry for the delay. Preparing for visitors.

I'm referring to the 2 black leads coming from the thermostat and the 2 marked with arrows (may not be on the correct screws) from the 24v power supply. All 4 of these were connected to the old gas valve. The black were piggy-backed but I separated them. I've attached a diagram that I made minus the 4 leads in question.

I'm referring to the 2 black leads coming from the limit switch - sorry.

Dummy me, I clicked on the big download button which I guess was an ad.

I actually have that manual. Still befuddled.

Post a photo of your valve. I think you might have the wrong one. The terminals should have been the same.

More photos.

This furnace was installed in '85 so it's old. The Robertson Unitrol gas valve only had 2 terminals so the connections were simple. One black and the white to one terminal and the other black and the tan to the other terminal.

One of them terminals don't do a thang like reg says. You won't get a reading between the dummy terminal and the other 2. So your 24 volts is goin to go between the 2 terminals that you get a reading from. Just in case you come across this again. Since you mentioned you had 3 terminals I wanted to be sure you didn't have a millivolt valve instead of a 24 volt valves. These valve come in a variety of different power ranges from line voltage ac to low voltage ac to millivolt.

Excellent. You verified my suspicions. The middle terminal does nothing.

Thank you gentlemen.
