Passing this along.

My stove is one of the ones effected, and from what I can gather by the recall, it is most likely an o-ring issue, as it seems to effect both the stove as well as the parts kit. Also on the web form, it said they would send you the parts when available.

Guess we’ll see!

Katadyn Products Inc. today announced a voluntary recall of the Optimus Nova and Optimus Nova+ Multifuel Expedition 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

Units: About 11,500

Manufacturer: Katadyn Products Inc., Wallisellen-Zurich, Switzerland

You can view the rest of the information of the recall as well as multiple ways to contact Katadyn if your stove is part of the recall at the following URL:


I received the following email from Katadyn this morning

Please accept our most sincere apologies for the trouble caused with your Optimus stove.

We just recently learned about a problem related to your stove model. The hazard is a very fine edge left over from tooling of the quick coupling and of the ON/OFF valve of the pump that may cause the o-rings to wear out faster and tear after only a few uses. In addition, the o-rings used on the ON/OFF valve and on the fuel hose on some of the stoves can swell in certain kinds of fuel.  Some Nova stoves of the latest production lots may have fuel hoses which are not completely crimped and could detach. One of these failures can cause fuel leakage posing a fire hazard to consumers. Katadyn Products Inc. will therefore replace your defective pump, o-rings and fuel line.

We will be contacting you within the next two weeks with an action plan for the replacement. Your stove has been assigned the case # XXXXXX.  Please refer to this for any further communication.

The Nova is built for a lifetime of use. With this pump and fuel line replacement, your stove will perform at the high level that you can expect from Optimus. Thanks in advance for your support.

If you have any questions please don’t hesitate to contact us.

Kind regards,
Bret Whitnah

Katadyn Recall
How to visually check if your stove is part of the recall

Update: 12/21/10

I’m happy to say that once the return authorization was issued, the process went very quickly.

I received my return authorization on November 24th, and I shipped it out on November 30th.

On December 9th it was shipped back to me, in which I received it a week later.

I am happy to have my stove back. I fired it up to make sure everything worked, and I double checked all the contents I shipped them to make sure everything was there in the extra parts kits that were also part of the recall.

I’m glad Katadyn jumped on getting this recall taken care of, and the promptness to it, once they had the go ahead to provide it.
