So I just inspected a furnace that had a bit of rollout on the start up. I was hoping for a second opinion on if this alone is an issue. There is some rust that I will be writing up for further evaluation. Any thoughts would be appreciated.
Direct vent, Cat IV, Natural Gas, In-shot burners, Manufactured 2004.
Some rust at exchanger ports that seems to coincide with the flame rollout on start up. However there is also indications of condensation leaking from AC & Vent.
Condensate & Corrosion issues aside Is this amount of rollout acceptable? (See Video) Or is there an ignition timing issue or something else?
