PEACE AND QUIET

Congratulations, you’re the proud new owner of one of our most advanced stoves. That must mean
you’re on your way to exciting, demanding adventures. We know that you’ve made a smart choice
with this stove and when you use it, you’ll know too. Get ready for great outdoor cooking, thanks to
over a century of success at Optimus.

Being the outdoor enthusiasts we are, we understand that you’re probably curious about your new
stove and anxious to try it out as soon as possible. But even if you have plenty of experience with
similar products, please read the manual so you become familiar with the specifics relating to this
stove.

All of us at Optimus hope that you will take the time to sit down and enjoy the peace and quiet unique
to food preparation in the Great Outdoors.

Good luck, and bon appétit!

SAFETY FIRST!

When you use your Optimus Nova+, you’ll be handling highly flammable fuels. If used incorrectly,
you will be putting yourself and everything around you in danger. Make sure that you’ve understood
everything in this manual before using the stove. Try it out and get to know it properly before you
head out for adventure.

Check that no fuel is leaking before you light the stove. If you have spilled any fuel, the safest thing is
to move the stove. If you discover fuel leaking from any part of the stove, the leak must be taken care
of before the stove is used. Never use a stove that is leaking fuel.

The Optimus Nova+ is designed for outdoor use only. A lit stove consumes oxygen and gives off carbon
monoxide. If you use the stove indoors in an unventilated area or in a tent, you run the risk of falling victim
to carbon monoxide poisoning.

Make sure that you never hold your face or any other part of your body over the stove. Also make
sure you keep your clothes away from the stove. Many materials used for outdoor clothing, sleeping
bags, etc. are highly flammable.

Be very careful when lighting a stove that has just been used. A hot burner can vaporize the fuel. The
fuel may ignite explosively. Allow the stove to cool properly before lighting it again.

Never leave the stove without supervision. Never leave children unattended near the stove.

Use Optimus Nova+ only for cooking food and boiling water.

EN - HOW YOUR STOVE WORKS

The Optimus Nova+ is a multifuel stove. This means that you can use a number of different liquid
fuels, such as gasoline, diesel and kerosene. Unlike propane gas, these are often easy to get hold of
even in the most remote corners of the globe. They also make your stove considerably more powerful
when used during winter trips.

Preparing food on a multifuel stove using liquid fuel is slightly more complicated than using a gas
stove. First off, the fuel has to be pressurized in order to make the stove as hot as possible. The gas
in a gas bottle is already pressurized when you buy it from the shop, but the liquid fuel you put in your
fuel bottle is not. Therefore, you have to pump up the pressure in the bottle yourself.

You also need to preheat the stove for a short time using a squirt of fuel. Preheating involves heating
up the burner to such an extent that the fuel is vaporized when it passes through the burner’s nozzle.
Vaporized fuel burns effi ciently with a blue fl ame and a hissing sound.

When your food is cooked and you want to shut off the stove, you turn the entire fuel bottle to OFF
position. This places the pump in a position whereby air comes out of the bottle instead of fuel. When
the fuel remaining in the hose has burned, the fl ame goes out on its own and the pressure remaining
in the bottle seeps out.

If you turn off the stove using the control valve only, fuel will remain in the hose and the bottle will stay
pressurized. This will cause a fuel spill when you dismantle the stove or transport it in your pack.

The following pages show you how to use the stove, step-by-step.

Fill the bottle with fuel and

1

Do not fi ll the fuel bottle to the brim. It should only be fi lled about ¾ full. You have
to leave some space for the pump and the air that will be compressed when you
pump up the pressure. To ensure proper usage of the “On / Off “ function by tur­ning the bottle, check the fuel intake hose is bent away from the pump cylinder.
The brass fuel fi lter holder should touch the interior wall of the fuel bottle. Check
that the seal is positioned correctly in its groove before you turn the pump into
position. The seal must be fl at and even all round. Screw on the pump properly
and wipe off any spilled fuel.

Read more about various fuels in the chapter on fuels.

screw on the pump.

WARNING! Make sure that you stay well away from a lit stove or naked
fl ame when you are fi lling the bottle with fuel. Use only Optimus fuel
bottles.

HOW YOUR STOVE WORKS - EN

Fold out the pot supports on the burner.

Make sure the fuel control valve is closed.

It gets very hot under the stove, so remember to place the stove on a
fi rm base which cannot catch fi re.

Make sure that the control valve is closed before pumping pressure
into the bottle.

Do not use pans with a diameter that exceeds 280 mm (11 inches). The
weight of the pan plus food should not exceed 4 kg (8.8 lbs.).

WARNING! Do not place the stove on or near fl ammable materials. Avoid
exposing the fuel bottle to heat. The bottle may explode if it is exposed to
heat. Only use wind screens approved by Optimus for use together with the
Optimus Nova+. Never cover the fuel bottle with the wind screen. There must
always be a clearance of at least 15 cm (6 inches) between the fuel bottle
and a pot or pan on the stove to prevent overheating of the fuel bottle.

Clear the nozzle in the burner.

3

All fuels contain contaminants that can block the nozzle in the
burner. The Optimus Nova+ has a built-in cleaning needle that
is used to clear the nozzle with ease. Move the multitool a few
times directly beneath the burner’s base nut. The magnets on
this tool force the needle to move, thereby clearing the nozzle.

Get into the habit of cleaning the stove before you start
preparing food. This will reduce the risk of the nozzle in the
burner getting blocked. See the section entitled “Cleaning and
maintenance” if the stove functions poorly even though it has
been cleared using the multitool.
