About the Vollrath FC-IDI-D2900
Vollrath model FC-IDI-D2900 is a two-hob induction cooktop that meets ENERGY STAR requirements for food-service equipment. The unit measures 28 in. long by 13 in. wide and 5 in. high.
Instead of heating a burner or element, induction heats the pan itself through a magnetic field. That gives near-instant response, no energy use when no pan is present, and a much cooler cook line than gas or radiant equipment.
Each of its two cooking zones covers 152 sq. in. (square, about 12.5 in. on each side). Total nameplate input is 7 kW at 240 V.
In ASTM testing it achieved a cooking-energy efficiency of 91% — that share of the electricity drawn ends up as heat in the pan contents. That is higher than 92% of the 25 commercial cooktop models in our database.

Safety information
- Connect the cooktop only to a grounded supply that matches the voltage on the data plate. Do not use extension cords, adapter plugs or power strips.
- Induction coils produce an electromagnetic field. People with pacemakers or other implanted medical devices should consult their physician and the device manufacturer before working close to an induction cooktop.
- Never heat an empty pan or a sealed can or pouch. Induction heats very quickly; an empty pan can overheat in seconds and a sealed container can burst.
- Do not place metal utensils, knives, foil or lids on the cooking zone — they can heat up. Keep magnetic-stripe cards and electronic devices off the surface.
- The glass-ceramic top gets hot from the pan and stays hot after cooking. Do not touch it until it has cooled.
- If the top is cracked or chipped, stop using it and disconnect power immediately. Spills can reach live parts through a crack.
- Keep air intake and exhaust openings clear and do not operate the unit on soft surfaces, towels or mats that can block airflow.
- Oil heats much faster on induction than on gas. Never leave hot oil unattended, and keep a Class K extinguisher nearby.
Installation and first-time setup
Plan for the unit's footprint of 28 × 13 in. (5 in. high) plus the ventilation clearances in the installation manual.
- Choose a stable surface
Set the unit on a level, sturdy, heat-resistant counter or the installation the manual specifies, with the side and rear clearances it calls for. Do not place it where the cord crosses a walkway.
- Keep it away from heat sources
Do not install next to fryers, broilers, ovens or charbroilers. Hot intake air makes the electronics overheat and shut down.
- Connect power
This unit is rated for 240 V and is a dual-voltage model; confirm it is set up or wired for your actual supply voltage as the installation instructions describe. At its 7 kW nameplate input it draws roughly 29.2 A on a single-phase supply. Have a licensed electrician provide a dedicated circuit and receptacle or hard-wired connection sized from the data plate.
- Check your cookware
Hold a magnet to the base of each pan. If it sticks firmly, the pan will work on induction; if it does not, it will not heat.
- First power-up
Place a pan with water on each zone, switch on and confirm the unit detects the pan, heats and runs its cooling fan. Remove protective film from the glass first.
Using your induction cooktop
Choosing cookware
| Works on induction | Does not work (unless it has a magnetic base) |
|---|---|
| Cast iron and enameled cast iron | Aluminum |
| Carbon steel and enameled steel | Copper |
| Magnetic stainless steel and induction-ready clad pans | Glass, ceramic and non-magnetic stainless steel |
Use flat-bottomed pans; warped bases lose contact with the glass and heat unevenly. Pans whose base covers most of the 12.5 in. square zone heat most evenly. Very small pans may not be detected at all.
Cooking on induction
- Start at a lower setting than you would on gas — induction delivers heat to the pan almost instantly.
- Preheat pans only briefly, and add oil or food before the pan reaches smoking temperature.
- Lifting the pan to toss or stir pauses heating; output resumes when the pan is set back down. This is normal.
- Use the power-level or temperature-control modes your model offers as described in the manual; temperature modes are well suited to frying and holding.
- Turn the zone off when you finish — although an induction hob draws almost nothing with no pan present, the controls stay live.
With two zones, assign each to a task (searing, simmering, holding) so cooks are not waiting on one another. Some multi-hob units share power between zones; if one zone loses power when another is turned up, check the manual for power-sharing behavior.
Food safety
- When holding soups, sauces or other hot foods on a zone, keep them at 135 °F (57 °C) or above and stir regularly; check with a calibrated probe thermometer.
- Cook foods to their FDA Food Code minimum internal temperatures — for example 165 °F (74 °C) for poultry — and verify with a thermometer.
- Clean and sanitize pans and utensils between raw and ready-to-eat foods.
Hob layout and test results
ENERGY STAR records test results for each cooking zone separately. Small differences between zones are normal and reflect coil size and position.

Care and maintenance
| When | What to do |
|---|---|
| After each use | Let the surface cool, then wipe the glass with a damp cloth and mild detergent and dry it. Use a glass-ceramic cooktop cleaner for marks. |
| Immediately | Wipe up sugary spills as soon as it is safe to do so; melted sugar can pit glass-ceramic surfaces. Lift burnt-on residue with a razor scraper held flat to the glass. |
| Daily | Wipe the housing and controls with a barely damp cloth. Never spray water or cleaner into the vents or let liquid pool around the controls. |
| Weekly | Clean the air-intake filter if your model has a removable one, and vacuum dust from the intake and exhaust openings. |
| Monthly | Inspect the cord, plug and glass top for damage, chips or cracks. |
| Annually | Have a qualified technician check cooling fans, coil connections and electronics, especially in greasy or high-heat locations. |
Troubleshooting
Most induction problems come down to cookware, airflow or the electrical supply. Work through these checks before calling for service.
| Problem | Possible cause | What to try |
|---|---|---|
| Zone does not heat or pan is not detected | Cookware not magnetic; pan base too small; pan off-center; warped base. | Test the pan with a magnet; use a larger, flat-bottomed pan centered on the zone. |
| Unit shuts off during cooking | Overheat protection: blocked vents, dirty filter, hot surroundings, or an empty or overheated pan. | Clear the vents and clean the filter; move the unit away from heat sources; let it cool before restarting. |
| Error code on the display | Brand-specific fault or protection message. | Note the code and consult the code table in your manufacturer's manual. |
| Buzzing, humming or clicking | Normal interaction with some cookware at high power; cooling fan; multi-layer pans. | Usually harmless. Reduce power or try a heavier, single-material pan if the noise is bothersome. |
| Uneven heating or a hot ring in the pan | Thin or warped pan base; pan much larger than the zone. | Use a heavier, flat pan sized to the zone. |
| Breaker trips | Circuit too small or shared with other equipment. | Have an electrician confirm the circuit matches the nameplate load and is dedicated to the cooktop. |
| Fan keeps running after switching off | Normal cool-down of the electronics. | No action needed; let it finish before unplugging. |
| Controls do not respond | Wet or greasy touch controls; control lock engaged (if equipped). | Dry and clean the control area; check the manual for unlocking. |
Energy use and running costs
Running every zone at the full 7 kW nameplate input would cost about $1.19 per hour at $0.17 per kWh. Real use is far lower: induction draws power only while a pan sits on an active zone, and most cooking happens at partial power. As a rough guide, an average of one-third of nameplate power over an 8-hour service day would cost about $3.17 a day.
With 91% cooking-energy efficiency, about 110 kWh of electricity is needed for every 100 kWh of heat delivered to the food. The remaining 9% is mostly lost from the pan sides and the electronics.
Because induction has no standby heat and adds little waste heat to the kitchen, it also reduces the load on air conditioning and makeup air compared with gas or radiant equipment. Actual costs depend on menu, hours and local electricity rates.
Frequently asked questions
What cookware works on the Vollrath FC-IDI-D2900?
Use pans with a magnetic base: cast iron, carbon steel, enameled steel or induction-ready stainless steel. If a magnet sticks firmly to the bottom, the pan will work. Aluminum, copper and glass pans will not heat unless they have a magnetic base plate.
How many cooking zones does the Vollrath FC-IDI-D2900 have?
It has two cooking zones. Each zone covers 152 square inches. The unit measures 28 by 13 inches and stands 5 inches high.
What power supply does the Vollrath FC-IDI-D2900 need?
It is rated for 240 V (dual voltage) with a nameplate input of 7 kW, which is roughly 29.2 A on a single-phase supply. Use a dedicated circuit sized from the data plate, installed by a licensed electrician where required.
How efficient is the Vollrath FC-IDI-D2900?
It tested at 91% cooking-energy efficiency under the ASTM test, with individual zones between 90% and 91%.
How much does it cost to run the Vollrath FC-IDI-D2900?
At full nameplate power (7 kW) it would cost about $1.19 per hour at $0.17/kWh. Typical use is a fraction of that, because induction draws power only while a pan is on an active zone and rarely runs at full output.
Is the Vollrath FC-IDI-D2900 ENERGY STAR certified?
Yes. It appears on the ENERGY STAR list of certified commercial cooktops, with a certification date of June 1, 2025.
