Boiler burn at end of burner tube

Recently had low cut off valve replaced, ever since realize one of the burner tubes is firing out the end. Make sense to me some debris, rust is causing an issue with this, so will a simple cleaning take care of it? If so am i cleaning just where the gas valve is or he entire tube? I appreciate the help in advance

    If there's debris and/or rust on the burner tubes, then yes, start there before trying to troubleshoot further. rust on the tubes may be an indication of leaking sections.
