    Sounds like it might be an ignition problem. Time to call a pro. Where are you located?

  • Natural gas or propane? I'd hire someone with a manometer to check gas pressures and also a combustion analyzer to check the fuel/air mix.

    I did record a new video of 3 mins, as you can see it iam not an expert but it's struggling, but eventually it heats up really good, only the beginning part is mysterious,

    Call them back. This should not have happened. Ask for a supervisor.
