Robin Kovar scored twice in the rout with netminder Stephen Fone outstanding between the pipes.
He turned aside 24 shots as Phoenix backed up their 3-2 win at Peterborough on Saturday.
Phoenix were simply too good for the Flames who came to the IceDome short on players.
That didn’t show until the second period but Luke Boothroyd and Michal Psurny broke their opponent’s resolve to make it 2-0 by the 28th minute.
Player-Coach Tony Hand was involved in both and he laid on the pass for Kovar’s first goal – and Manchester’s third – right at the end of the period.
Phoenix turned the screw in the third and James Archer swept home the fourth on the powerplay just before Kovar notched his second.
Robert Schnabel tallying Manchester’s sixth and final goal eight minutes from time.
Whilst Phoenix can’t read a lot into the game because the Flames were down on numbers, Hand would be pleased to see his charges cope without the injured Frantisek Bakrlik and the form of Fone.
The forward was forced off the ice early in Saturday’s victory down in Peterborough and it did effect how the top line performed.
But they rallied well and deserved all four points this weekend.
Saturday’s 3-2 win came via penalty shots after it was tied 2-2 at the end of overtime.
Andy McKinney scored both Phoenix’ goals with James Archer and Fone producing the goods in the shootout to down the Phantoms.
Manchester will look to keep up the momentum when they take on Peterborough Phantoms and Milton Keynes Lightning this coming Sunday and Monday.
