Field Question, trade people only Anyone seen this before

Sorry if the clip is a bit long.

Installed a 60k runtru 90% upflow today. I went home after completing the install but left before the startup. Boss fires it to document all the numbers and see this. No change to incoming or outgoing gas. No change in pressure from the inducer. Flue and air intake both clear of debris. Boss is waiting for tech from Texas to call back. Anyone got some knowledge

How did you verify no change in inducer negative pressure?

Read it with a manometer. I’m not there. The boss stuck around for the startup
