1. Please keep children and pets at a safe distance at all mes.
2. While operang, your Cr30 oven will reach very high temperatures. Always use protecve
heat resistant gloves to handle tools and pots.
3. Beware of flying sparks from the mouth of the oven.
4. Ensure that no combusble materials are within range of your oven at any me.
5. Do not shut the oven’s doors while there is fire with flames inside the oven. Closing the door
will cut off oxygen to the fire, eventually weakening the flames or causing a sudden fire
erupon when the door is removed and oxygen flows into the oven again.
6. Do not alter the oven in any way, it has been designed in order to opmize its safety and
funconality.
7. Do not burn contaminated wood (with chemicals), rubbish, or flammable fluids in your oven.
8. DO NOT CARRY OVEN WHEN HOT OR WARM.
Safety guidelines
1. Always use natural untreated firewood, never pressure treated or painted wood such as
old fence posts. We advise that you try to use silver birch.
2. Do not use pellets, chipped wood products, or sappy wood within your oven.
3. NEVER USE ANY TYPE OF ACCELERANT, SUCH AS PETROL, PARAFFIN OR SIMILAR
PRODUCTS. THESE ARE EXTREMELY DANGEROUS AND CAN LEAD TO EXPLOSIONS
WITHIN YOUR OVEN.
Fire Ignion Guidelines
NEVER PUT YOUR HANDS OR ARMS INSIDE OR OUTSIDE THE OVEN WHEN
HOT, UNLESS YOU ARE WEARING ADEQUATE HEAT RESISTANT GLOVES.
CAUTION: TEMPERATURES OVER 450°C / 850°F MAY CAUSE THE DETERIORATION
OF THE OVEN AND ITS COMPONENTS.

*Please see line 5 of safety guidelines
*DO NOT CLOSE THE OVEN DOOR WHILE THERE IS FIRE WITH FLAMES INSIDE THE OVEN*
1 - Build a tower of kindling over a natural firelighter in the middle of the refractory brick floor,
towards the front of the oven.
2 - Keep adding kindling pieces to the fire (please respect safety guidelines) every couple of
minutes to help the fire gain size and heat; aer a few minutes the fire should have built to
a reasonable size and the heat should now be quite intense (when you are unable to hold
your hand any closer than about 9” / 23cm from the mouth of the oven).
3 - Allow the fire to keep building for a further 5 minutes (keep feeding it) and the fire should
then be ready to push to the back of the oven using the embers rake.
4 - Once the fire has been pushed back, add around 3 or 4 pieces of quality wood (please
respect the combusble guidelines), we recommend pieces of around 8-10” x 2“ / 20 x 5cm.
5 - You should now have a good bed of red embers along with a healthy flame and are now
ready to start cooking.
6 - Every 15 minutes or so, you will see the flames are start to dissipate. If you wish to keep
cooking, simply add 3-4 more 6” / 15cm logs accordingly in order to maintain a healthy fire
and heat. Keep in mind that closing the oven’s door will cut off oxygen to the fire.

1. Over me, the top of the opening and the door on your oven can become black, as the soot
from the fire builds up. To minimize, simply clean the oven opening using a so sponge with
soap and water.
2. The floor of the oven should be cleared of ashes and embers when fully cold. Once you
have removed the embers, please clean the refractory brick by using a brush to dust it
down and remove any embers residue.
1. Please ensure that the ashes and have fully cooled down before disposal (natural cooling
can take several hours).
2. It is perfectly acceptable to turn the refractory brick over between uses.
3. DO NOT USE THE REFRACTORY BRICK WHEN WET AS IT ABSORBS MOISTURE,
CAUSING IT TO CRACK (WHICH DOES NOT DIMINISH BRICK’S ABILITY TO COOK ).
4. Before storing the oven for a long period apply WD-40 or paraffin wax, using a cloth or
coon buds, to the exterior metal surfaces of the oven to protect against corrosion.
5. When not in use, the oven should be covered or shielded from the elements.
Maintenance
NEVER PUT YOUR HANDS OR ARMS INSIDE OR OUTSIDE THE OVEN WHEN
HOT, UNLESS YOU ARE WEARING ADEQUATE HEAT RESISTANT GLOVES.

Benets of cooking with re
When cooking with re, it is essenal to start by making a high re,
allowing the oven to reach a high temperature. Once the oven is
heated, the refractory brick oor becomes a radiator, enabling food
to cook from underneath as well as from above. In your Cru Oven, the
re and smoke are drawn through the oven and across the food as it
cooks, adding an incredible avor to your cooking.
This is something impossible to achieve when cooking by other means
(or methods). Heat will allow food to cook, while ames will roast. The
balance between the heat within the oven and the ames present is
the key to a perfect result.
You can cater to for a lot of people in a short period and at a fracon of
the cost. Cooking becomes easy once you have mastered the balance
between heat generated from embers (allowing for slow cooking) and
ames (more intense heat that roasts). Food that creates a lot of juices
like sh, meats, etc., should be cooked in appropriate cookware for
the recipe and heat of the oven.
Enjoy your Cr30 oven !
