Does this type of roaster require a flue?

Yes, all gas-fired coffee roasters require a suitable exhaust flue system to vent combustion gases and smoke generated during the roasting process safely.

What maintenance is typically involved?

Regular cleaning of the roasting drum, chaff collector, and cooling tray is essential. Periodic inspection of gas lines, burners, and electrical components is also recommended.

Can this roaster handle different roast profiles?
