Due to ongoing product improvements, specications and dimensions are subject to change and correction without notice
or incurring obligations. Determining the application and suitability for use of any product is the responsibility of the installer.
Additionally, the installer is responsible for verifying dimensional data on the actual product prior to beginning any installation preparations.
Third party incentive and rebate programs have precise requirements as to product performance and certication.
All products meet applicable regulations in effect on date of manufacture; however, certications are not necessarily granted for the life of a product.
Therefore, it is the responsibility of the applicant to determine whether a specic model qualies for these incentive/rebate programs.
