Arrived at location on 8/9/21 - Had to disconnect multiple plumbing fittings and remove before moving unit. Also had to move unit out by myself in order to gain access to back. Unit was very heavy and awkward due to a broiler attached to the top of it. Took notice after disassembly of unit that gas lines were steel and corroded very badly. Found leak in back bottom right corner of oven were burner supply line runs through the back of unit. Supply line was heavily corroded and had a fairly massive area of degradation in which gas could leak through. Unit has been placed out of service due to the location of the leak. It cannot be isolated. Had to move unit back into place by myself and reattach and reconnect all plumbing devices to unit. Returned to location 8/17/21 - Removed compromised parts. Installed new gas feed for oven and upon inspection found that the pilot line had been damaged from the leak as well. Removed, fabricated, and installed new pilot feed line. Leak chec
