DANNY Ings made it a ‘magnificent seven’ and Sam Vokes opened his account for the season as Clarets survived a second half onslaught at Hillsborough.
Ings’ header midway through the first half saw the striker register a goal in the seventh successive game, including a productive pre-season.
And when striker partner Vokes grabbed his first goal of the season soon after, Sean Dyche’s men put crucial daylight between themselves and Wednesday.
David Prutton replied with a second half header to set up a nervy finish at Hillsborough.
But after a dogged and magnificent rearguard, Burnley survived an aerial onslaught to record a terrific victory to build on the opening day draw at home to Bolton.
The Clarets were unchanged for the third successive game, with the only change coming on the bench, where fit-again Ben Mee replaced Luke O'Neill.
But it was the hosts who had the livelier start, with shots narrowly off target by Helan and Antonio.
However, Sam Vokes had a chance to open the scoring in the 14th minute when he beat the offside trap to race onto Wallace’s neat chip.
However, the striker chested the ball away from goal and fired over on the volley with the first touch when a little more composure might have paid dividends
As the Clarets settled into the game Junior Stanislas curled a free kick just wide after being fouled 30 yards from goal.
And Wednesday were indebted to Chris Kirkland when Vokes seemed certain to score in the 19th minute.
A flowing move began with David Jones feeding Stanislas, who in turn picked out Dean Marney on the edge of the Owls box.
The midfielder’s shot deflected kindly into the path of the Clarets’ Welsh striker eight yards out, but with the goal at his mercy Kirkland somehow made up ground and turned his effort round the post.
Heaton was soon equal to Maghoma’s long-range free kick with a fine save as the game continued to ebb and flow.
And now the Owls were pressing, with the lively Antonio causing constant problems for the defensive pairing of Kevin Long and Kieran Trippier.
The winger crossed deep for David Prutton to fire into the side netting and was then involved in the move that eventually saw Danny Lafferty shin an attempted clearance inches wide of Heaton’s right hand post.
But just after the half hour mark it was the Clarets who made the breakthrough. Ross Wallace found acres of space and waited for Ings to make the run into the six-yard box. The cross was perfection and the Clarets striker did the rest with a point-blank header past Kirkland to open the scoring.
And five minutes later Burnley were in dreamland when Vokes doubled the lead. This time the deep right wing cross was even better from Kieran Trippier and Vokes rose highest at the far post to plant a header back across goal and just inside the post.
Wednesday were floored - and made a change at the break as young full back Rafael Floro made way.
And as the hosts sought a lifeline, a mad scramble almost reaped its rewards, as the Clarets threw a succession of bodies in the way of quickfire attempts.
And the Clarets again survived when Trippier was sold short by a pass out from the back and Helan’s cross was nodded inches wide by towering striker Atdhe Nuhiu.
But the threat on the counter-attack was ever-present - and when Dean Marney made a lung-busting run down the right flank and cut the ball back to the corner of the box, Wallace was inches away with a daisy-cutter into the side netting.
But Wednesday’s aerial bombardment was always looking their best threat - and it took another top save from Heaton down at his post to claw away Nuhio’s firm header.
And it was a firm header from Prutton that rewarded the Owls’ second half pressure with 19 minutes remaining, racing in to power a right wing cross.
Sean Dyche’s response was to replace Wallace with David Edgar as an extra defensive shield.
And the Canadian could have wrapped things up within five minutes, racing in unmarked to meet Jones’ right wing corner and flashing a header wide of the far post.
As the clock ticked down, so the balls into the Burnley box increased. But led magnificently by skipper Jason Shackell and fellow centre back Kevin Long, with Tom Heaton unflappable behind them, the Clarets held firm!
