Robertshaw will stop making Mercury Safeties at the end of 2007. This will include all FMDA (my 4020 series) and FMEA (my 4030 series). The forced obsolescence will affect the new equipment of Blodgett, SouthBend, Bakers Pride and Vulcan as they are the only OEM's still using the mercury safety on new production.
Manufacturing of the FSS & FSD's (my 4070 series) which are mercury filled flame switches will stop at the same time. This has upset many OEM's who are still using on thier assembly lines. The list would include American Range, Toastmaster, Keating, Wolf, Lang, Garland, Duke, Imperial, SouthBend, Tri-Star, Rankin, and of course Blodgett.
Expect to see considerable price increase around July. I plan to order enough to cover the last time buys of CCC, ICS, and FMP as well as for me (Uni-Line) to have available as long as needed for the aftermarket.
