Solid fuel stove Petromax RF33 1 cooking zone 6.5 kg

The Petromax Rocket Stove rf33 combines the rocket stove principle with a chimney-augmented combustion chamber to deliver efficient biomass burning and concentrated heat for outdoor cooking. Its L-shaped arrangement of fuel support, combustion chamber and vent concentrates combustion in a small insulated space, while the cast-iron top stores and transfers heat for cooking. The compact RF33 is intended as a robust, portable solid fuel stove for use in outdoor kitchens, camping and other open-air cooking situations.

Advantages

The RF33 achieves efficient combustion through an optimized air supply and stack effect, reducing fuel consumption while producing high heat output in a confined combustion chamber. The cast-iron cooking surface retains heat for even cooking. The L-shaped fuel support allows easy feeding of wood and biomass, and integrated handles improve portability and safe handling. The stove’s insulated body limits heat loss and protects the exterior.

Suitable for

• Camping and backpacking trips where wood fuel is available
• Outdoor kitchens and backyard cooking with solid fuel
• Emergency cooking and off-grid power outages
• Small-scale outdoor catering or communal cooking

How to use

Place the RF33 on a stable, heat-resistant surface with adequate clearance from flammable materials. Load small pieces of dry wood or other biomass into the fuel support and ignite them, allowing the stack effect to establish a steady draft through the combustion chamber and vent. Adjust feeding to control flame intensity; the cast-iron top will absorb and distribute heat for cooking. Use the integrated handles only when the stove has cooled sufficiently or with appropriate heat protection. Follow local fire safety rules and never leave the stove unattended while burning.

Usage recommendations

For best results use dry, well-seasoned wood or compact biomass like pine cones; avoid burning treated or painted wood. Allow the stove to reach stable combustion before placing cookware on the cast-iron top to ensure even heat transfer. Clean ash from the combustion chamber regularly and store the stove dry to prevent corrosion.
