Wiring white rodgers zone valves

Hi I have a new weil mclain cga-4 standing pilot boiler and 2 white rodgers 1311-102 zone valves. How do i wire the zone valves to the boiler? The boiler has 2 wires coming from the transformer relay R and G terminals marked 24 v thermostat. Is this where i wire the wires from the zone valves? If you have a diagram it would be most helpful. Thanks. Scott

Hi Scott, do you already have the zone valves wired up? I think you know that those valves need a particular 3 wire thermostat, correct? ( curious why you chose those? ) I would have used the 1361 series so as to be able to use off the shelf 2 wire thermostats...

Here's the PDF for your zone valves, Figure 9 comes closest to what you need... of course you only have two valves so ignore the 'extras'.

Where that diagram shows connections to T1 and T2 on the boiler control, you will use the R and G on your boiler. On your valves, terminals 2 and 5 are connected internally. You will wire terminal 3 and (2 OR 5) to the G and R on your boiler.

Questions?

Thanks for replying NJ Trooper. I have deceided to replace the white rodgers valves since they are 30 years old and install Taco Zone Sentry Zone valves instead. I looked at the wiring diagram and i think i know how to install them. Have you heard much about these valves? Any good? Scott

Sorry, I know as much about them as you do! I've read all the literature and stuff... I like the idea of an actual 'ball valve' as the operator... but hands on experience with them? zip... I haven't heard anything BAD about them though, and that's GOOD!
