2-zone wiring for Weil McCLain boiler

I'm trying to wire (2) Honeywell V8043 E zone valves to my Weil McClain CG series boiler. I have a standing pilot, and will use a 24V transformer. My question is regarding how to wire both zones in series with the existing burner and damper controls. There are two leads supplied with the boiler as it comes pre-wired, one that supplies 24V and the other that connects to the burner and damper controls. Given that I will now supply both stats with 24V from the transformer, can I connect both the other lead from both stats to the terminal on the boiler that operates the controls? The wiring diagrams from the Honeywell valves and the boiler are a little confusing. Any simple diagrams would be appreciated.

Here is the wiring diagram for reference....

Basically the red leads from the end switch go to the circ control @ T T

The yellow gets tied one side to the transformer and the other to the t stat.
