The dual flow burner is a defining feature of DCS ranges, rangetops, and cooktops. This glossary entry explains what makes it different from an ordinary gas burner and why it matters for everyday cooking.
What it means
“Dual flow” describes a sealed burner designed to operate cleanly across an unusually wide heat range. Instead of being good at only high or only low heat, a dual flow burner delivers a powerful high flame for boiling and searing and steps down to a gentle, stable simmer without cutting out.
Why DCS designed it
- One burner handles both a rolling boil and a delicate sauce or melt.
- The sealed design keeps spills out of the burner box for easier cleaning.
- A wide turndown reduces the need for multiple specialized burners.
How it cooks
At full output the burner produces intense, even heat for searing and wok-style cooking. Turned down, it holds a low, consistent flame for simmering without the flame guttering or going out – the trait home cooks value most. This versatility is why DCS pro ranges suit serious cooking.
Caring for the burner
Keep the burner cap and ports clean so the flame stays blue and even; clogged ports cause weak or yellow flames. See our range burner cleaning guide for the routine. If a burner will not simmer or hold flame, our range repair team can service the valve.

Turndown ratio explained
The key spec behind a dual flow burner is its turndown ratio – the gap between its highest and lowest stable output. A high turndown means one burner can both boil a stockpot and hold chocolate at a melt. Ordinary burners with a narrow turndown force you to move the pan to a smaller burner for low-heat work.
Common questions
- Is it the same as a simmer burner? No – a dedicated simmer burner only does low heat, while a dual flow burner does both extremes.
- Why does my simmer flame go out? Usually a clogged port or a worn valve – clean first, then service the valve if needed.

The dual flow burner pairs with DCS’s sealed-burner cooktop design and convection ovens to make a complete pro range. For ignition issues on these burners, see our range symptom diagnostics or schedule a technician.
Dual Flow Burner: Key Takeaways
To recap on dual flow burner: work through the simple checks first, keep the appliance clean and correctly set up, and address small symptoms before they grow. The guidance above on dual flow burner reflects how our certified technicians approach the same issues in the field, and following it keeps your DCS appliance performing the way it was built to.
- Start with the easiest, lowest-cost checks and confirm the basics before replacing parts.
- Use only genuine DCS-specified parts so performance and safety are not compromised.
- Keep up a regular maintenance routine, which prevents most problems and protects long-term value.
- Know when a job needs a professional, especially anything involving gas, sealed-system refrigeration, or mains wiring.

When to call a DCS technician
It is worth being clear about the line between sensible owner maintenance and work that belongs with a professional. Routine cleaning, simple resets, and basic setup are well within reach for most owners and are exactly where this guide focuses. Anything involving a gas connection, a sealed refrigeration system, internal wiring, or a part that must be calibrated or pressure-tested is different: those repairs carry real safety and warranty implications and should be handled by a certified technician with the correct tools and genuine DCS parts. A DCS appliance is a long-term investment built from 304 stainless to last for decades, so it is almost always worth maintaining and repairing properly rather than letting a small problem compound. When in doubt, a quick diagnostic visit removes the guesswork, protects the appliance, and gives you a clear, written quote before any work begins so there are never surprises.
