The home side started with two 16-year-olds and two 17-year-olds in their side and there was a welcome return, albeit to the bench, of defender Stevie McHoul after a long time out through injury.
The Shipyard had the better of the early exchanges as a Ferrier effort forced a good save from Lumsden in the Duns goal although Connor Devanney almost put Duns ahead but his effort hit the post.
The Dingers deeservedly took the lead on the 10 minute mark when a great shot by Connor Devanney caught out keeper Melia and they grabbed a second goal after 22 minutes when 16-year-old Reagan Graham cracked home a great right foot shot.
A further fine strike by Mark Weatherburn four minutes later gave the home side a comfortable 3-0 lead at the interval.
Duns pressed after the restart, continuing to cause problems for a flat Burntisland defensive line that relied on off-side calls to halt the wave of Duns attacks. However, it was the visitors who pulled a goal back when Paul Ferrier found himself in space to score from just outside the box.
Brendan Napier scrambled home a second goal for Burntisland and Duns were beginning to feel the pressure, having lost a two goal lead against Kelso the previous week.
Duns, however, extended their advantage in the 74th minute when Devaney placed a great free kick beyond Melia.
The outcome of the game was settled beyond any doubt five minutes later when Gary Waddell broke clear and stroked the ball home to make it 5-2. Burntisland continued in their endeavour’s with both Ferrier and Napier creating openings but shooting wide before the final whistle.
