If I read your valve model correctly, it's an intermittent spark valve that can also be used as a universal valve.

In your application, after the inducer closes the pressure switch, a Honeywell S8610 (or similar) module should open the pilot valve and initiate spark to light the pilot.

It probably has a Honeywell ST9120 control board as well, to control the inducer and the blower.

After the pilot proves, the module will open the main valve. The valve should have three terminals..."PV" (pilot valve), "PV/MV" (common), and "MV" (main valve).

Selling them a new furnace won't teach you a thing. Figure it out and learn from it.
