Uniflasy Gas Burner Attachment for Karu 12 Pizza Oven, 12" Propane Kit — Fast Heat & Precise Control

The Uniflasy gas burner attachment converts a Karu 12 (and compatible 12G) pizza oven to reliable propane heat for faster, more controllable baking.

This compact kit replaces or augments wood-fired cooking by adding a propane burner, hose with valve, and mounting hardware so you can reach high temperatures quickly without constant fire management. It’s designed to bolt onto multi-fuel ovens and gives consistent top heat for crisp crusts while letting you switch back to wood or charcoal as desired. The unit is intended for use with the oven door removed and chimney installed; follow the provided ignition guidance and safety steps.

How quickly will this burner heat my pizza oven?

The Uniflasy burner delivers rapid heat-up so you can start cooking sooner. In real use it can push the oven toward very high temperatures in a short period, reducing preheat time compared with wood-only operation. That faster ramp-up also shortens turnaround between pies.

• Reaches high oven temperatures in roughly 20–30 minutes under typical conditions
• Burner flame pattern targets the dome for quick stone heat-up
• Consistent top heat helps achieve even browning without constant fuel tending

Will the attachment fit my Karu 12 or similar ovens?

This kit is engineered to fit Karu 12 and Karu 12G style ovens and other 12" models that accept a gas adapter, but confirm compatibility before purchase. Installation uses two self-tapping screws and the package includes the screws, a propane hose with valve, and the burner itself. Note the operational constraint: the oven door must be removed and the chimney kept on while the burner is in use.

• Includes burner, propane connection valve hose, and two mounting screws
• Designed for Karu 12 / Karu 12G and similar 12" pizza ovens
• Requires oven door off and chimney installed during gas operation

How does the gas option change cooking control and results?

Adding propane gives precise, steady heat that’s easier to regulate than a wood fire, so crust and toppings cook more uniformly. You can adjust flame intensity during baking to prevent over-browning while keeping the stone hot for a crisp base. The burner also broadens the oven’s use for fast searing or other quick-cook items.

• Simple knob control for fine temperature adjustments while cooking
• Even roof flame coverage improves top-of-pizza consistency
• Enables quick searing and faster cook cycles for diverse dishes

What safety and ignition steps should I follow?

Follow the manufacturer’s ignition procedure to avoid safety-valve triggers and ensure reliable lighting. Open your propane tank’s flow slowly, then push in and turn the control knob slowly to allow gas to reach the burner before ignition. After the ignition click, hold the knob for a few seconds to stabilize the flame.

• Open tank flow gradually to prevent regulator or safety valve activation
• Push in and slowly turn control knob anti-clockwise for about three seconds
• After ignition click, hold the control knob depressed for an additional few seconds

Who is this for? Grillers and pizza enthusiasts who own a Karu 12, Karu 12G, or compatible 12" multi-fuel oven and want faster preheat, easier temperature control, and consistent top heat will benefit most. It’s ideal for home cooks who alternate between wood and gas, backyard chefs seeking quicker pizza nights, and anyone wanting to reduce time spent tending a wood fire while retaining the option to revert to traditional fuels.
