Jeff,

American Standard is owned by TRANE in Tyler Texas. Their general telephone number is 1-877-698-7263. If you want their technical assistance you can call their Customer Relations number and they will put you through to the technical department in your area. Customer relations can be reached at 903-581-3660. If push comes to shove our local tech's here in Carrollton, TX (outside of Dallas) is 972-406-6000 and ask for the technical department.

Good luck.

Emmanuel
