INTEGRAL RECIRCIRCULATING SYSTEM

Dear Mr. Pool:

In reply to your e-mail message received today, I offer the following.

Products in the KNLZ category (as well as KNKG) are evaluated to UL710B. It used to be that UL197 and supplement SB in UL197 was the standard that they were evaluated to. Basically, UL197 and Supplement SB became UL710B. There is no more Supplement SB in UL197 (9th Ed.).

Any information and documentation involving UL Mark services are provided on behalf of Underwriters Laboratories Inc. (UL) or any authorized licensee of UL.

Very truly yours,

Fred Zaplatosch

Staff Engineer 3015CNBK
