Aircraft
We started both engines at the gate; taxied out to the runway and took off with nothing out of the ordinary happening. After the completion of the after takeoff checklist we ran the ice protection pneumatic test. During this test we had the red master warning chime; and noticed it was for the Number 1 bleed leak. We also smelled a burning scent. We turned the ice protection override knob back to auto; and closed the number 1 bleed valve. The Pilot Monitoring began to run the QRH while the Pilot Flying took the radios and the continued to fly the airplane. At this time we [Requested Priority Handling]; and began getting vectors back to the filed. By the time we finished the QRH we were able to get the bleed leak inscription to go away. We then landed without incident.
During the climbout we initiated the ice protection (pneumatic) test. While performing the test; we observed the 4 'open' inscriptions on the overhead panel; and then a few seconds after that an EICAS 'BLD 1 LEAK' warning message appeared on the EICAS. We also smelled fumes. We then turned the ice protection knob back to the 'auto' position and closed the Number 1 bleed valve which had a visible red 'LEAK' inscription illuminated. The Captain continued to fly the airplane; took the radios; and called for the QRH. I ran the QRH while the Captain [Requested Priority Handling] and received radar vectors back to ZZZ. While following the steps of the QRH; the 'BLD 1 LEAK' EICAS message extinguished. We landed in ZZZ without incident.
EMB-145 Captain reported a Number 1 engine bleed leak during climbout resulting in a return to departure airport.
