Down 2-1 in the second period, he latched on to James Archer’s break and sent an upstoppable shot into the top corner.
Phoenix then scored four goals in just over two minutes to seal the win.
Sheffield got off to the best possible start when Lubomir Korhon scored after just 44 seconds.
But Phoenix levelled 26 seconds later through Michal Psurny as he fired a shot off Richard Bentham’s pass.
Manchester spurned a 5 on 3 powerplay in the eighth minute and it was no surprise when Korhon notched his second to give the Dogs a 2-1 period lead.
Both teams stacked the neutral zone in the second but Sheffield had the first chance when Bentham went to the bin for Tripping.
Archer had other ideas though and on the penalty kill he broke free and fed Kovar for his wonderful finish.
It would be another ten minutes before the next chance and Phoenix didn’t disappoint.
Steeldogs’ coach Andre Payette was in the box for slashing and Psurny put the home side ahead on 37:03.
22 seconds later Frantisek Bakrlik made it 4-2 and just before the end of the 39th minute Ben Wood had made the game safe.
Bakrlik adding the insurance marker on 39:11.
Sheffield scored twice in the final period to make the score look respectable but they couldn’t overhaul that second period blitz.
Phoenix’ resilience, which keeps them top of the EPL, was evident on Saturday when they overcame Slough 4-3 in overtime.
The game was tied until Bakrlik grabbed the win in the 63rd minute.
Luke Boothroyd, Bentham and Psurny with the other goals.
