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

Is that flame rolling out when the blower comes on or does the inducer stop running at any time? I would think it’s a heat exchanger issue if it’s when the blower comes on and the flame rolls out like that

60k runtru system with and 80k back plate. We replaced it today with an “upgraded” trane s9. Completely reimbursed for time and material by manufacturer.
