Fire hazard triggers recall of Optimus Nova stoves

Katadyn Products Inc. recently announced a voluntary recall of the Optimus Nova and Optimus Nova+ Multifuel Expedition stove.  Stoves sold between January 2009 and September 2010 are affected by this recall. Consumers should stop using these recalled products immediately.  

Name of Product: Optimus Nova and Optimus Nova+ Multifuel Expedition Stoves

Hazard: The conditions described below, which result in torn or expanded O-Rings, can cause fuel leakage and create a fire hazard to consumers. A sharp edge left over from tooling for the quick-action coupling and the ON/OFF fuel supply valve of the pump may cause the O-rings to tear.

Also, the O-rings used in the fuel hose and in the ON/OFF valve on some stoves can expand with the use of certain kinds of fuel. Some Nova stoves of the latest production lots may have fuel hoses which are not completely crimped and could get detached.

Gotta love it when product quality goes in the crapper after a company changes hands.

I wasn't aware that Optimus had sold. I still have my SVEA, a 111 and a 88+, all of which I really like and have had no problems with.
