The design
Based on a simple enclosed waste-oil burner design using:
- •A steel ammunition box or equivalent airtight steel enclosure
- •A glass or heat-resistant front panel for flame visibility
- •An intake pipe for air supply (computer-style fan powered)
- •An exhaust pipe for combustion gases (exits through wall or window — mandatory)
- •A simple wick-based burner using vegetable oil as fuel
- •A temperature-rated seal on all joints
- •External surface temperature limits to prevent burns
Safety requirements — non-negotiable for all builds

- ✓A BS EN 50291 certified carbon monoxide alarm must be installed in the same room at time of installation

- ✓Installation must be documented with photos and signed off by a Community Pillar or admin before use
