As a result of the receipt of a number of reports of fuel leakage in the field and after quality assurance analysis, Katadyn Products Inc. has decided to voluntarily recall some Optimus Nova and Optimus Nova+ Multifuel Expedition Stoves. 

If you bought your stove between January 2009 and September 2010 and it has a black burner housing and shows a QA-number from QA000011-QA007313, please fill in the form here to file your request for an exchange.

The QA-number of the stove is located on the side of the black burner housing. All Nova and Nova+ stoves with silver burner housing have no QA-number and are not affected. Please also see their FAQs to identify your stove.
