Eddie Howe declared himself slightly disappointed to be denied a winning start to his career as Burnley manager.
Battling Scunthorpe halted their own horrendous home record of six successive defeats with a goalless draw at Glanford Park.
In a game of few chances at either end it was Clarets' substitute Chris Iwelumo who came closest to breaking the deadlock with an effort which struck the outside of the post.
Howe said after the contest: "I'm slightly disappointed not to be coming away with all three points.
"It's been a long week since going in to take charge at Turf Moor and it seemed a long time before we finally got round to playing a game of football.
"Scunthorpe is a difficult place to come even though I know their home record has not been too good in recent games.
"Defensively I thought we were strong, it was just in the final third where we could not find the quality we need.
"We do have targets in the transfer market who we are looking at but I'm not going to name any names.
"The squad I have inherited here is a strong one and we do not need to do that much work in bringing new players in."
Scunthorpe, facing a battle to avoid relegation to League One, started brightly.
They might have had an early lead from a corner when a flick from Sam Togwell was headed off the line by Burnley midfielder Wade Elliott, with keeper Lee Grant struggling.
Chris Dagnall curled a left-foot effort just wide for the home side while winger Martyn Woolford tested keeper Grant with a good effort.
Burnley's main threat came from midfield man Chris Eagles who twice went close, first lifting a shot from a corner just over the top and then seeing a 25-yard drive drift just wide.
At the start of the second half Scunthorpe went close again through Woolford but it was Burnley who gradually began to take charge.
The introduction of Iwelumo midway through the half quickly made a difference.
He had only been on the field for three minutes when he got in a shot which went behind off the outside of the post.
Iwelumo went close again when he got goal-side of the Scunthorpe defence to get in a close-range effort which brought the best out of goalkeeper Josh Lillis.
Scunthorpe, with four players in the side making their home debuts, hung on for a deserved point.
"I'm delighted with the result," said United manager Ian Baraclough.
"I was slightly worried about the factor that new manager Eddie Howe might have coming in at Burnley.
"I asked my players to go out and deliver a performance and I thought they battled well on a difficult pitch.
"We created a number of chances and if we could have done a little better in the final third then we might have got all three points.
"But I was pleased with the new players we have brought in. They have added some steel to the dressing room and some experience onto the pitch.
"If we can go on and continue to produce performances like this then I am sure we can get ourselves out of trouble.
"Despite bringing a number of players in this week, the chairman says the cheque book is still not closed and I am still looking to bring in a striker before the January transfer deadline closes."
