The organ was shipped in a forty-foot container from the Ruffatti factory in Padua and was installed and voiced in the Church by Organ Arts, Ltd., of San Francisco, the United States representatives for the Ruffatti firm. The installation was completed in January of 1983. The main body of the instrument is located in the rear Gallery of the Church, and the Antiphonal Divisions are in the front for the accompaniment of the choir and further support of congregational singing. One unique feature is that there is a separate independent moveable computerized console controlling the entire instrument at each end of the Church.

Saint Brigid's wishes to acknowledge the superb craftsmanship of the many people involved with the installation, namely, Roger Brown, Gary Clark, Mark Cleveland, Leland Chambers, and William Lopez. Voicing and final tuning were done by Roger Hardesty, David Sacre, and Francisco Ruffatti. Supervising all phases of the work was Reid Betten, President of Organ Arts.

The Ruffattis have many notable installations in the United States including the Catholic Cathedrals of San Francisco and Atlanta; The Crystal Cathedral in Garden Grove, California; Coral Ridge Presbyterian Church in Fort Lauderdale, Florida; the new Concert Hall for Ricks College in Rexburg, Idaho; and the large new organ for the San Francisco Symphony currently being installed in Davies Symphony Hall."
