Switching a Commercial Kitchen from Gas to Induction: A Pre-Quote Retrofit Checklist

For an early feasibility review, bring that evidence to ProChef’s commercial kitchen design team. You can also compare the current commercial induction cooktop range, but equipment should not be ordered until the selected model’s current data sheet has been reconciled with the site assessment.

Why this is a project, not a like-for-like appliance swap

Induction heats compatible cookware directly, so it can respond quickly, reduce open-flame heat in the room and stop drawing full cooking energy when the pan is removed. The Australian Building Codes Board’s current commercial-cooking electrification assessment schedules gas and electric commercial cooking equipment side by side — including induction cooktops, with rated input and dimensions — and assesses where an electrification scenario requires an electrical-infrastructure upgrade.

The same report’s cost modelling shows how much a result can change once extra substation capacity has to be added. That is why a countertop trial that works on one outlet does not prove that a full cookline can be converted economically. A venue may need new distribution-board capacity, submains, protection, isolation, cable routes or supply-authority work. Only the site-specific design can establish that scope.

The conversion also changes how chefs work. Pan recognition, control steps, pot diameter, vessel material, lifting frequency and clean-down differ from open burners. Some processes may transfer directly; high-output wok, chargrill or solid-top work may need a specialised induction or other electric solution rather than a generic flat hob. A staged or mixed transition can be legitimate for an existing venue when the governing approvals allow it.

Gas-to-induction retrofit: decision summary

Step 1: record the existing cookline accurately

Create one row for every gas appliance, including equipment that is used only on peak days. Photograph the rating plate and record:

• appliance type, brand and model where legible;
• overall width, depth and height;
• gas type and rated input from the plate or manual;
• menu processes performed on it;
• pans, pots or wok sizes used;
• realistic peak-hour duty pattern;
• canopy zone and fire-suppression coverage;
• adjacent clearances, benches and heat-sensitive finishes;
• condition, service history and replacement priority;
• whether the appliance must remain available during the cutover.

Do not translate megajoules per hour directly into a shopping-list kilowatt figure. Gas input, heat transfer, cooking surface, recovery and control behave differently. Define the required kitchen output first, then compare documented equipment performance through a controlled trial.

Use the wider commercial cooking equipment range to identify possible equipment classes, not to assume every gas appliance has a one-for-one induction equivalent.

Step 2: map the menu and busiest service period

Make a process map for the kitchen’s most demanding 60–90 minutes. A useful worksheet includes:

Separate processes that only appear concurrent from those that truly overlap. A six-burner range may have six controls but only four active pans during the busiest period; alternatively, a single high-output stockpot process may dominate the replacement decision.

Record recovery between batches, not only first heat-up. Include large cold loads, sauces requiring low control, pans lifted repeatedly, and any workflow that currently uses flame around the sides of a wok. For each proposed station, define a pass/fail result such as time to boil the normal water volume, portions completed within the peak window, acceptable product quality and safe operator movement.

Step 3: run a controlled menu trial

Before redesigning the line, trial representative commercial equipment with the actual chef, pan and product wherever practical. A small plug-in unit is useful for learning and limited processes, but it cannot prove the performance or electrical implications of a full modular cookline.

Record:

• equipment model and current data sheet;
• pan material, flatness and base diameter;
• product quantity and starting temperature;
• power/control setting and elapsed time;
• batch recovery and repeatability;
• noise, fan exhaust and staff comfort observations;
• operator reach, lifting and cleaning notes;
• pass/fail result for the menu process.

Do not publish trial figures as a universal performance claim. They apply only to the tested combination and conditions.

Step 4: audit every pan, pot and utensil

Induction requires compatible magnetic cookware. The City of Darebin’s current business induction guidance recommends a magnet as an initial compatibility check, but that is only the first screen.

For each vessel, check:

• whether a magnet holds firmly across the usable base;
• base diameter against the selected induction zone;
• whether the base is flat, stable and undamaged;
• full operating weight and safe lifting method;
• handle clearance and adjacent-pan conflicts;
• quantity needed at peak service;
• availability of compatible replacements for specialist shapes.

Budget for lids, inserts, wok bowls and spare pans as well as the obvious saucepans. Test legacy cookware rather than assuming all stainless steel is compatible. Follow the selected manufacturer’s limits for base size, weight and materials.

Step 5: build the proposed electrical load schedule

Create a schedule from current manufacturer data, not reseller summaries or remembered model numbers.

For early planning only:

connected cooking load = sum of each selected unit’s rated input × quantity

This is not the final maximum-demand calculation and is not an instruction to size cables or protection. A licensed electrical professional must assess diversity, phase balance, existing loads, demand, fault levels, isolation, protection, cable routes, distribution-board capacity and any network or landlord constraints under the current rules for the site.

Compare the cooking conversion with refrigeration, dishwashing, hot water, HVAC and other large loads that may run during the same peak. If supply capacity is marginal, the project team may investigate staging, load management or a different equipment mix, but only within the selected manufacturers’ instructions and an approved electrical design.

For a plain-language primer before that professional assessment, see ProChef’s single-phase versus three-phase commercial kitchen equipment guide.

Step 6: check the switchboard, tenancy and cable path

Ask the electrical professional to document at least:

• incoming supply and metering arrangement;
• main switch and distribution-board capacity;
• available ways and physical board space;
• current peak-demand evidence where available;
• phase loading and proposed balance;
• route, length and access for new circuits or submains;
• isolation and emergency-shutdown arrangements;
• landlord, strata, centre-management or network approvals;
• fire-stopping and making-good requirements;
• future headroom, with the assumptions stated.

The expensive constraint may sit outside the kitchen. A tenancy can have a neat switchboard yet be limited by the building riser, shared transformer, embedded network or landlord allocation. Put that uncertainty in the feasibility stage rather than allowing it to become a variation after equipment arrives.

Step 7: review ventilation, make-up air and fire systems

Removing a flame can reduce combustion products and some direct heat, but it does not automatically remove the need for a canopy or allow an existing exhaust system to be downsized. Grease, smoke, steam, vapour and cooking-process heat still matter.

Give the mechanical reviewer the old and proposed equipment schedules, appliance locations, cooking processes and duty. Confirm:

• canopy coverage over the revised line;
• exhaust and make-up-air implications;
• clearances and ventilation openings required by the equipment;
• effect on fire suppression, interlocks and emergency controls;
• heat rejection into the room and HVAC impact;
• whether approvals or certification must be updated.

ProChef’s custom stainless-steel fabrication and exhaust-canopy service asks for the kitchen plan, cooking-equipment schedule and available mechanical drawings before a canopy quote. That evidence must not be replaced by a general claim that induction needs no extraction.

Step 8: plan gas isolation and decommissioning

Gas work must be scoped and completed under the rules for the venue’s state or territory. Energy Safe Victoria’s commercial-kitchen guidance, for example, identifies AS/NZS 5601.1:2022 as the applicable Australian Standard and notes that the Standard itself does not contain comprehensive instructions on how to complete an installation.

The project brief should identify:

• which appliances and branches are being removed;
• whether any gas equipment will remain operational;
• safe isolation, capping or removal of redundant services;
• meter or supply changes where applicable;
• required tests, certificates and records;
• coordination with canopy interlocks and emergency controls;
• labelling and as-built updates.

Do not instruct unlicensed staff to isolate, cap or alter gas pipework. Confirm the current requirements for the exact address and scope.

Step 9: measure the physical installation

Induction electronics need manufacturer-specified cooling and service access. Record the equipment envelope and the space needed to install, ventilate, clean and maintain it. Check:

• bench, cabinet or modular-line dimensions;
• air-intake and exhaust openings;
• side, rear and overhead clearances from the current manual;
• splash, grease and cleaning exposure;
• pot overhang, handle paths and adjacent-station conflicts;
• bench load and equipment weight;
• floor, plinth and castor details;
• route through doors, corridors, lifts and loading areas;
• safe access to isolation and service points.

Do not copy a generic clearance into the build drawing. The selected equipment manual and the approved project design govern the installation.

Step 10: price the whole project, not just the appliances

Ask quotes to separate:

1. equipment and accessories;
2. electrical design, boards, protection, cabling and connection;
3. any building, supply-authority or metering work;
4. gas decommissioning;
5. ventilation, make-up air, HVAC and fire-system changes;
6. stainless-steel or joinery modifications;
7. compatible cookware;
8. delivery, lifting, installation and commissioning;
9. temporary kitchen or lost-trading allowance;
10. training, warranty, servicing and spare-equipment strategy;
11. approvals, documentation and making good;
12. contingency tied to named unresolved risks.

A simple comparison can be prepared without inventing savings:

annual operating-cost estimate = measured annual energy use × current tariff + planned servicing and consumables

Use measured or defensible duty data, current tariffs and the actual proposed models. Keep demand charges, seasonal variation, finance, tax treatment, ventilation/HVAC changes, maintenance and downtime visible rather than burying them in a single payback number. The Green Building Council of Australia’s practical guide to electrification for existing buildings, published with the Clean Energy Finance Corporation, provides broader retrofit context, but it is not a substitute for the site quote.

Step 11: stage the cutover and commissioning

For an operating venue, define the sequence before orders are placed:

• surveys and approvals completed;
• long-lead equipment and switchgear confirmed;
• enabling works tested where possible outside service hours;
• temporary menu or production location agreed;
• gas equipment isolated only when replacement capacity is ready;
• equipment installed to the approved design;
• electrical and gas records completed;
• ventilation and safety interfaces checked;
• chef trial and staff training completed;
• peak-load commissioning and defects list recorded;
• rollback or contingency trigger agreed for critical failures.

A staged conversion can reduce operational risk and create real production data before the entire line changes. It can also create temporary service conflicts, so the mixed-stage design must be reviewed rather than improvised.

The pre-quote evidence pack

Send the following files with the request:

• dimensioned kitchen plan and photos;
• existing gas-equipment schedule and rating plates;
• proposed equipment schedule with current data sheets;
• menu/process and peak-production worksheet;
• induction trial results;
• cookware inventory;
• electrical information supplied by the licensed assessor;
• canopy, make-up-air and fire-system information;
• tenancy/building and approval constraints;
• delivery route and access limits;
• preferred staging and shutdown window;
• required completion date and named decision-makers;
• list of assumptions, exclusions and unresolved risks.

ProChef’s commercial kitchen fit-out team can coordinate equipment, installation and project interfaces once the feasibility inputs are clear. The Lotus equipment range is a relevant brand destination for reviewing current gas and electric cookline formats, but only verified live models and current manufacturer data should be used in the final schedule.

Common retrofit mistakes

• Ordering cooktops before the electrical assessment.
• Comparing burner count with induction-zone count without mapping the menu.
• Assuming a magnet test alone proves cookware suitability.
• Treating a plug-in bench trial as proof of a complete-line design.
• Assuming induction automatically eliminates exhaust requirements.
• Ignoring building supply, landlord or embedded-network constraints.
• Leaving gas decommissioning and certification out of the quote.
• Forgetting ventilation openings and electronics service access.
• Publishing generic efficiency or payback claims as a site result.
• Scheduling the shutdown before long-lead equipment and switchgear are confirmed.

Frequently asked questions

Can every gas appliance be replaced with induction?

No. Many pot-based processes can move to induction, but the correct electric replacement depends on the menu and equipment class. Wok, chargrill, fryer, oven, stockpot and solid-top processes may require specialised induction or another electric technology. Trial the process and compare current commercial data.

Will the kitchen need three-phase power?

Possibly, but it cannot be decided from the article or the word “commercial”. Some small units use lower-current single-phase connections; modular or multi-zone equipment can have much larger requirements. The complete load schedule and site assessment determine the solution.

Can we remove the exhaust canopy after changing to induction?

Do not assume so. The cooking process can still produce grease, smoke, steam, vapour and heat. A qualified mechanical/fire review should assess the proposed line against current requirements and the site’s approvals.

Does induction always cost less to run?

No universal saving should be promised. Induction can transfer energy efficiently to compatible cookware, but the site result depends on equipment duty, electricity and gas tariffs, demand charges, ventilation and HVAC effects, maintenance, cookware and infrastructure cost.

Should an existing venue convert all at once?

Not necessarily. A staged approach may reduce downtime and prove key processes, while a full cutover may avoid repeated works. Compare both sequences with the building, trade, operational and approval constraints visible.
