Orient defender Jean-Yves Mvoto put into his own net before Jack King scrambled in the second.
Hakeeb Adelakun's injury-time tap-in sealed victory for the Iron.
Scunthorpe are 14th in the third tier having won just one of their past five league matches.
But Chelsea have struggled this season in defence of their Premier League crown and have bad memories of the FA Cup from last season, when they were beaten 4-2 by League One Bradford in the fourth round.
However, the Blues have won 17 consecutive third-round ties.
The Iron will travel to Stamford Bridge on Sunday, 10 January.
