CPSC, Viessmann Manufacturing Company (U.S.) Inc., Announce Recall of
SR-RN-2 and SR-RN2R Boiler Control
PRODUCT: Boiler Control - Viessmann Manufacturing Company (U.S.) of
Warwick, R.I. is recalling 190 SR-RN2 or SR-RN2R controls, which are
installed in Atola-RN Boilers. The recalled units were manufactured
between December 1998 and December 2001. This is the entire production
of these controls. (The controls do not have a date code that can be
seen by consumers.) The boilers were sold nationwide by wholesalers and
distributors.
PROBLEM: The controls have an electronic relay that may fail in a manner
that will allow the burner to operate and by-pass the interlock with the
flue damper. The interlock assures proper operation of the damper for
removal of combustion gases. If the interlock fails, excess carbon
monoxide emissions may occur.
INCIDENTS/INJURIES:No injuries have been reported.
WHAT TO DO: Consumers who have one of these boilers should contact their
local distributor or Ms. Ulli Hiltz, the Viessmann Manufacturing Company
contact, at 888-843-2772 between 8:30am and 5:00 pm ET Monday through
Friday. Viessmann Manufacturing Company will install a wiring module in
suspect boilers which will put a redundant switch in series with the
switch that may erroneously close and by-pass the safety interlock with
flue damper.
Viessmann Manufacturing Company has contacted distributors and
wholesalers and made arrangements for them to contact customers and make
arrangements to retrofit the Atola-RN Boilers with SR-RN2 or SR-RN2R
Controls.
