What Restaurant Equipment Needs to Go Under a Hood?

One of the biggest questions when planning a commercial kitchen is:

What restaurant equipment needs to go under the exhaust hood?

In general, commercial cooking equipment that produces grease-laden vapor or smoke is typically installed under a Type I commercial kitchen hood.

Equipment that primarily produces heat, steam, or moisture without grease may require a Type II hood.

Common equipment that is often installed under a Type I hood includes:

• Commercial fryers
• Charbroilers
• Griddles
• Commercial ranges
• Wok ranges
• Tandoors
• Broilers
• Salamanders
• Some commercial ovens
• Some tilt skillets and braising pans

However, hood requirements should never be determined by an equipment category alone.

The exact requirement can depend on:

• The specific appliance
• What foods are being cooked
• Whether grease or smoke is produced
• The manufacturer's installation instructions
• The equipment listing
• Local building, mechanical, and fire requirements

This guide explains which types of restaurant equipment commonly go under a hood and what restaurant owners should consider when planning a commercial cook line.

Why Do Restaurants Need Commercial Kitchen Hoods?

Commercial cooking can release large amounts of:

• Heat
• Smoke
• Grease
• Steam
• Moisture
• Cooking odors

A commercial kitchen exhaust system captures these cooking emissions and removes them from the kitchen.

The hood is usually positioned above or near the cooking equipment so it can capture the rising plume before it spreads throughout the building.

Type I vs. Type II Restaurant Hoods

Before looking at individual appliances, it helps to understand the two major commercial kitchen hood categories.

Type I Hood

A Type I hood is designed for cooking processes that produce:

• Grease-laden vapor
• Smoke
• Heat associated with grease-producing cooking

These are commonly called grease hoods.

Type II Hood

A Type II hood is designed primarily for:

• Heat
• Steam
• Moisture
• Condensation

from equipment that does not produce grease-laden vapor.

You can learn more in our guide to Type I vs. Type II Commercial Kitchen Hoods.

Quick Guide: What Equipment Usually Goes Under a Hood?

This table is only a general starting point. Always confirm the requirement for the exact appliance and installation.

Do Commercial Fryers Need to Go Under a Hood?

Commercial fryers are one of the clearest examples of cooking equipment typically installed beneath a Type I hood.

Frying produces:

• Grease-laden vapor
• Heat
• Cooking emissions

Whether the fryer uses gas or electricity does not eliminate those emissions.

Nishi Enterprise carries Commercial Deep Fryers for restaurants and other foodservice operations.

Do Electric Fryers Need a Hood?

Electric equipment is not automatically hoodless.

An electric fryer can produce grease-laden vapor just like a gas fryer.

The type of cooking taking place is often more important than whether the appliance is powered by gas or electricity.

Some specially listed reduced-emission or ventless equipment may have different installation requirements, but this should be confirmed for the exact model and location.

Do Commercial Charbroilers Need a Hood?

Commercial charbroilers are generally installed under Type I ventilation.

Cooking burgers, steaks, chicken, kebabs, and other proteins can generate significant:

• Grease
• Smoke
• Heat

Charbroilers can be among the heavier-duty pieces of equipment on a restaurant cook line.

Do Commercial Griddles Need a Hood?

Commercial griddles used for typical restaurant cooking are commonly placed under a Type I hood.

Foods such as:

• Burgers
• Bacon
• Sausage
• Cheesesteaks
• Chicken
• Eggs cooked with oil or grease

can produce grease and cooking vapors.

Again, an electric griddle is not automatically exempt simply because it does not burn gas.

Do Commercial Ranges Need a Hood?

Commercial ranges are commonly placed beneath Type I hoods because of the wide variety of cooking performed on them.

A range may be used for:

• Sautéing
• Pan frying
• Braising
• Cooking sauces
• Cooking proteins
• Boiling

Some of these processes produce considerably more grease and smoke than others.

Nishi Enterprise carries Commercial Ranges in multiple sizes and configurations.

Does a Range Need a Hood if You Only Boil Water?

This is where hood questions become more complicated.

The physical appliance may be capable of many different cooking methods.

Even if a restaurant currently plans to use a burner primarily for boiling, the equipment itself may still be part of a cook line designed for grease-producing cooking.

Do not assume a range can operate without appropriate ventilation based only on one intended menu item.

Do Wok Ranges Need a Hood?

Commercial wok ranges generally operate as part of a Type I cook line.

Wok cooking can create significant:

• Heat
• Oil vapor
• Smoke

especially during high-temperature stir-frying.

Nishi Enterprise carries Commercial Wok Ranges.

Do Tandoors Need to Go Under a Hood?

Commercial tandoors produce intense heat and may produce grease and smoke when cooking items such as:

• Tandoori chicken
• Chicken tikka
• Seekh kebabs
• Lamb
• Fish
• Paneer

Commercial tandoor installations should therefore be planned with the appropriate restaurant ventilation system.

The Shaan commercial tandoors sold by Nishi Enterprise are intended to be installed according to the manufacturer's ventilation and installation requirements.

You can browse Commercial Tandoors from Nishi Enterprise.

Do Stock Pot Ranges Need a Hood?

Stock pot ranges are powerful burners designed to support large cooking vessels.

They may be used for:

• Soup
• Stock
• Curries
• Sauces
• Large-volume boiling

Whether and what type of hood is required depends on the appliance and cooking process.

A stock pot range used as part of a commercial cook line should be included when the kitchen ventilation system is being designed.

Nishi Enterprise carries Commercial Stock Pot Ranges.

Do Commercial Hot Plates Need a Hood?

A commercial hot plate is essentially a compact burner unit without the full oven base of a restaurant range.

The hood requirement depends on what is cooked on it.

If the hot plate is used for grease-producing cooking such as frying or sautéing, it should not be assumed that it can operate without Type I ventilation.

Do Salamander Broilers Need a Hood?

Commercial salamander broilers are commonly placed under or around the main Type I cook line.

They may be used for:

• Finishing steaks
• Broiling proteins
• Browning dishes
• Melting cheese

Some of these applications can generate grease and smoke.

The exact installation depends on the specific appliance.

Does a Cheese Melter Need a Hood?

Cheese melters and salamanders may look similar, but they can have different intended uses and heat output.

Whether a particular cheese melter needs to be under the hood depends on:

• Its listing
• What food is heated in it
• Manufacturer instructions
• Local requirements

Do Commercial Ovens Need a Hood?

There is no single answer that applies to every commercial oven.

Restaurants use many kinds of ovens, including:

• Convection ovens
• Deck ovens
• Combi ovens
• Pizza ovens
• Rotisserie ovens
• Conveyor ovens

The hood requirement may depend on:

• Fuel type
• Food being cooked
• Grease production
• Equipment listing
• Manufacturer instructions

Does a Convection Oven Need a Hood?

Some commercial convection oven installations require ventilation, particularly when the oven is used for cooking foods that produce grease or smoke.

Other listed oven applications may have different requirements.

Check the exact model instead of applying one rule to every convection oven.

Does a Combi Oven Need a Hood?

Combi ovens combine cooking methods such as:

• Convection heat
• Steam
• Combination cooking

Because restaurants can use a combi oven to cook proteins and many other foods, hood requirements depend heavily on the model and intended cooking application.

Nishi Enterprise carries RATIONAL Commercial Cooking Equipment, including combi cooking equipment.

Always review the exact installation requirements before planning the kitchen around a combi oven.

Do Pizza Ovens Need Hoods?

Pizza ovens come in many forms:

• Gas
• Electric
• Wood-fired
• Deck
• Conveyor

These different designs can have different ventilation requirements.

Do not assume that every pizza oven uses the same hood system.

Does a Conveyor Oven Need a Hood?

Some commercial conveyor ovens may require ventilation based on:

• Food being cooked
• Equipment listing
• Heat output
• Manufacturer instructions

Some specially listed equipment may have alternative ventilation arrangements.

Do Rotisserie Ovens Need a Hood?

Rotisserie cooking can involve meats that release substantial grease during cooking.

For that reason, commercial rotisserie equipment should be carefully evaluated when planning Type I ventilation.

Do Tilt Skillets Need to Go Under a Hood?

Tilt skillets, also called braising pans, can perform many cooking methods.

They may be used for:

• Sautéing
• Braising
• Pan frying
• Simmering
• Cooking sauces

Because some of those processes produce grease or smoke, many tilt-skillet installations are planned under appropriate commercial ventilation.

Do Steam Kettles Need a Hood?

A steam-jacketed kettle primarily used for liquids may create substantial heat and steam rather than grease.

Depending on the application, this type of equipment may be associated with Type II ventilation.

However, the exact requirement depends on the appliance and local installation requirements.

Do Pasta Cookers Need a Hood?

Pasta cookers can generate large amounts of:

• Steam
• Heat
• Moisture

Because they generally do not produce the same grease load as fryers or charbroilers, their ventilation requirements may be different.

This is a good example of why Type I and Type II hoods are separate categories.

Do Steamers Need a Hood?

Commercial steamers can release considerable steam when operated or opened.

Depending on the equipment and installation, a Type II hood may be used to capture:

• Steam
• Heat
• Condensation

Do Commercial Dishwashers Need a Hood?

High-temperature commercial dishwashers can release a large amount of heat and steam into the dishwashing area.

A Type II condensate hood may be used over certain dish machines to capture that moisture.

This is different from a Type I grease hood used over fryers and charbroilers.

What Equipment Usually Does Not Need a Cooking Hood?

Equipment that does not cook food or generate significant cooking emissions generally does not require a commercial cooking hood solely because it is located in a kitchen.

Examples normally include:

• Commercial refrigerators
• Commercial freezers
• Refrigerated prep tables
• Work tables
• Food processors
• Commercial mixers
• Cold beverage equipment
• Ice machines
• Storage shelving

Nishi Enterprise carries Commercial Refrigeration, Food Prep Equipment, and Commercial Work Tables that typically serve different roles from hooded cooking equipment.

Does a Commercial Microwave Need a Hood?

Many commercial microwaves are installed without a traditional cooking hood.

However, the exact application and manufacturer's installation requirements should still be reviewed.

A microwave should not automatically be treated as equivalent to a fryer, griddle, or charbroiler simply because it heats food.

Does a Rice Cooker Need a Hood?

Many electric commercial rice cookers are used as countertop equipment without a traditional grease hood.

They primarily produce heat and steam rather than grease-laden cooking vapor.

However, always check the specific appliance and local requirements.

Does an Immersion Blender Need a Hood?

No cooking hood is generally needed simply to operate an immersion blender.

An immersion blender is food-preparation equipment rather than heat-producing cooking equipment.

Nishi Enterprise carries Commercial Immersion Blenders.

Does a Commercial Mixer Need a Hood?

Commercial mixers generally do not require a cooking hood because they mix ingredients rather than cook them.

Nishi Enterprise carries Commercial Mixers for restaurant and bakery kitchens.

Gas vs. Electric Equipment: Does It Change the Hood Requirement?

One of the most common misconceptions is:

"Electric equipment doesn't need a hood."

That is not a safe assumption.

The cooking emissions matter.

An electric fryer can still produce grease.

An electric griddle can still produce smoke.

An electric broiler can still cook fatty foods.

So electrical power does not automatically make an appliance hoodless.

Does All Gas Equipment Need a Type I Hood?

No.

Fuel type alone does not determine hood type.

The appliance design, combustion requirements, cooking process, manufacturer instructions, and local requirements all need to be considered.

What Is Ventless Restaurant Equipment?

Some commercial cooking appliances are specifically designed and listed for operation without a traditional externally ducted cooking hood under certain conditions.

These may be marketed as:

• Ventless cooking equipment
• Ventless ovens
• Ventless fryers
• Self-contained cooking systems

These appliances may use built-in systems to control cooking emissions.

Does Ventless Equipment Mean You Can Put It Anywhere?

No.

"Ventless" does not mean the appliance has no installation requirements.

You still need to consider:

• Equipment listing
• Manufacturer instructions
• Electrical requirements
• Clearances
• Fire protection requirements
• Local approval

Can You Avoid Installing a Hood by Buying Electric Equipment?

Not automatically.

If electric cooking equipment still produces grease or smoke, appropriate ventilation may still be required.

If avoiding traditional ventilation is an important part of the project, look specifically for equipment that is listed for the intended ventless or reduced-emission application and confirm it with the local authority before purchasing.

Can Multiple Pieces of Equipment Share One Hood?

Yes. Restaurant cook lines commonly place several appliances under one properly designed hood.

For example, one hood may cover:

• Six-burner range
• Fryer
• Griddle
• Charbroiler

However, the hood needs to be designed around the entire equipment lineup.

What Happens if One Appliance Needs Type I and Another Needs Type II?

When multiple appliances are placed under the same hood and one of them requires Type I ventilation, the shared hood is generally designed as a Type I system.

This is one reason the entire cook line should be planned together rather than selecting a hood appliance by appliance.

Can You Add Another Fryer Under an Existing Hood?

Possibly, but you should not assume that open physical space means the hood can support another appliance.

Adding equipment can change:

• Cooking load
• Heat production
• Grease production
• Required capture area
• Fire-suppression coverage
• Gas demand

The existing ventilation and fire-suppression system should be reviewed before adding major cooking equipment.

Can You Replace a Range With a Charbroiler Under the Same Hood?

Not automatically.

A charbroiler may create a very different grease, smoke, and heat load than the appliance it replaces.

Any significant cook-line change should be evaluated before installation.

Can You Rearrange Equipment Under a Hood?

Sometimes, but changing the order of appliances can affect:

• Hood capture
• Fire-suppression nozzle coverage
• Gas connections
• Electrical connections
• Workflow

Do not assume equipment can be moved anywhere underneath the hood without reviewing the complete installation.

Why Hood Size Depends on the Equipment Underneath

A commercial hood is designed around the cooking equipment it serves.

Factors can include:

• Equipment width
• Equipment depth
• Cooking duty
• Heat production
• Grease production
• Hood configuration

This is why hood planning should happen at the same time as equipment planning.

What Is Cooking Duty?

Commercial cooking appliances may be considered different cooking-duty levels based on the amount of heat and cooking emissions they produce.

A light-duty appliance does not place the same demand on a ventilation system as a heavy-duty charbroiler or wok range.

Restaurant owners do not generally need to calculate these requirements themselves.

The important point is that different cooking equipment can require very different ventilation.

Why Your Menu Matters

The same general equipment category can sometimes be used for very different foods.

Consider a griddle.

One restaurant may use it for:

• Burgers
• Bacon
• Sausage

Another might use a cooking surface differently.

The actual cooking process helps determine the amount of grease and smoke produced.

Why Hood Planning Should Come Before Equipment Purchasing

A common mistake when opening a restaurant is purchasing cooking equipment before confirming the hood.

A restaurant may buy:

• Fryer
• Range
• Charbroiler
• Griddle

and later discover that the existing exhaust system was not designed for the proposed cook line.

That can create delays and additional construction costs.

Existing Restaurant vs. New Restaurant

Hood planning matters in both situations.

New Restaurant

You can design the cook line and ventilation together.

Existing Restaurant

You may need to design the new menu and equipment package around the ventilation system already in the building.

This can be especially important when taking over a former restaurant space.

Do Not Assume a Former Restaurant Has the Hood You Need

A building having an existing commercial hood does not mean that hood is automatically appropriate for your concept.

The previous restaurant may have used completely different equipment.

For example, replacing a relatively light cooking lineup with:

• Multiple fryers
• Charbroiler
• Tandoor
• High-output wok range

can substantially change the kitchen's cooking load.

Restaurant Hood Planning for an Indian Restaurant

An Indian restaurant cook line may contain:

• Tandoor
• Commercial range
• Stock pot range
• Fryer
• Wok range

Many of these appliances can produce substantial heat, grease, and cooking emissions.

The hood should therefore be planned together with the entire Indian restaurant equipment package.

Nishi Enterprise carries Commercial Tandoors, Stock Pot Ranges, Wok Ranges, and other Commercial Cooking Equipment.

Restaurant Hood Planning for a Burger Restaurant

A burger restaurant may use:

• Griddle
• Charbroiler
• Fryers
• Range

These appliances can create a significant grease and smoke load and are commonly grouped beneath Type I ventilation.

Restaurant Hood Planning for a Chinese Restaurant

A Chinese restaurant may use:

• Wok ranges
• Fryers
• Ranges
• Stock pot burners

High-temperature wok cooking in particular can create substantial heat and cooking emissions.

Restaurant Hood Planning for a Pizzeria

A pizzeria may have:

• Pizza oven
• Fryer
• Range
• Cheese melter

The exact ventilation layout depends heavily on the type of pizza oven and additional cooking equipment.

Restaurant Hood Planning for a Cafe

A cafe with mostly:

• Cold sandwiches
• Pastries
• Coffee
• Refrigerated foods

may have much different ventilation needs than a full-service restaurant with a fryer and charbroiler.

This is why the menu should be finalized before the kitchen equipment package is designed.

What About a Restaurant With No Hood?

A space without a traditional commercial cooking hood may still support some foodservice concepts.

A restaurant may focus on equipment and preparation methods that are appropriate for the space, such as:

• Cold preparation
• Commercial refrigeration
• Approved countertop equipment
• Listed ventless cooking equipment where permitted

However, the business concept should be designed around what the building and local authority allow.

Can You Open a Restaurant Without a Type I Hood?

Possibly.

Not every foodservice concept performs grease-producing cooking.

Examples could include certain:

• Cafes
• Cold sandwich concepts
• Bakeries
• Dessert shops
• Beverage concepts

depending on the actual equipment used.

The important distinction is what the restaurant cooks, not simply whether the business is called a restaurant.

Should You Buy Equipment Before the Hood Is Designed?

Ideally, the equipment package and hood should be coordinated together.

The hood designer needs to know information such as:

• Equipment manufacturer
• Model number
• Width
• Depth
• Fuel type
• Cooking application

Changing the equipment after the hood is designed can affect the ventilation plan.

Why Equipment Spec Sheets Matter

Do not design a cook line from approximate equipment descriptions such as:

• "36-inch range"
• "Fryer"
• "Griddle"

The exact manufacturer and model provide important information for the kitchen designer and installer.

Restaurant Hood Equipment Checklist

Before finalizing your cook line, make a list of every heat-producing appliance and record:

• Manufacturer
• Model number
• Equipment type
• Width
• Depth
• Gas or electric
• What foods will be cooked
• Manufacturer ventilation instructions

Then review the complete lineup with the appropriate kitchen design, ventilation, fire-suppression, and local approval professionals.

Frequently Asked Questions

What restaurant equipment needs to be under a hood?

Commercial cooking equipment that produces grease-laden vapor or smoke is generally installed under Type I ventilation. This commonly includes fryers, charbroilers, griddles, ranges, wok ranges, and similar grease-producing cooking equipment.

Does every restaurant need a hood?

No. A restaurant that does not perform cooking requiring grease or steam exhaust may have different ventilation requirements.

Do commercial fryers need a hood?

Commercial fryers are generally installed under Type I hoods because frying produces grease-laden cooking vapor.

Does an electric fryer need a hood?

Generally yes for normal grease-producing frying. Being electric does not eliminate the cooking emissions produced by the food and oil.

Do commercial ranges need hoods?

Commercial ranges are commonly installed under hoods because they can be used for grease-producing cooking. The exact requirement depends on the appliance and use.

Does a griddle need a hood?

A restaurant griddle used for typical grease-producing cooking is commonly installed beneath a Type I hood.

Does a charbroiler need a hood?

Commercial charbroilers are generally installed beneath Type I ventilation because they can produce substantial smoke and grease.

Does a wok range need a hood?

Commercial wok ranges are commonly installed under Type I ventilation because high-temperature wok cooking can create grease and smoke.

Does a tandoor need a hood?

Commercial tandoor installations should be planned with appropriate commercial ventilation based on the equipment manufacturer requirements and local approval.

Does a commercial oven need a hood?

It depends on the oven, fuel type, equipment listing, foods being cooked, and manufacturer requirements.

Does a combi oven need a hood?

It depends on the specific combi oven, what is being cooked, its listing, and local requirements.

Does a pizza oven need a hood?

Ventilation requirements differ between gas, electric, wood-fired, conveyor, and deck ovens. Check the exact oven.

Does a dishwasher need a hood?

Some high-temperature dishwashers use Type II condensate hoods to remove steam and moisture.

Does a rice cooker need a hood?

Many countertop electric rice cookers are used without traditional grease hoods, but the exact appliance and local installation requirements should be checked.

Does a commercial refrigerator need a hood?

No cooking hood is normally needed simply for a refrigerator because it does not cook food.

Does a commercial mixer need a hood?

Commercial mixers generally do not require cooking hoods because they are food-preparation rather than cooking equipment.

Does electric restaurant equipment need a hood?

It can. The heat source is not the only consideration. Electric equipment that produces grease or smoke can still require appropriate ventilation.

Can you put multiple appliances under one hood?

Yes. Commercial cook lines commonly have multiple appliances beneath a single properly designed hood.

Can I add another fryer under my existing hood?

Possibly, but the hood capacity, appliance arrangement, fire-suppression coverage, utilities, and local requirements should be reviewed first.

Can restaurant equipment be moved around underneath the hood?

Changes to equipment location can affect ventilation capture and fire-suppression coverage, so significant cook-line changes should be reviewed before equipment is moved.

Who decides whether restaurant equipment needs a hood?

The determination is based on the equipment manufacturer's instructions, applicable codes, equipment listing, cooking process, and the local authority having jurisdiction.

Final Thoughts: What Restaurant Equipment Needs to Go Under a Hood?

The simplest way to think about restaurant hood requirements is:

If the cooking process produces grease or smoke, it will commonly require Type I ventilation.

This often includes:

• Fryers
• Charbroilers
• Griddles
• Commercial ranges
• Wok ranges
• Tandoors
• Broilers
• Other grease-producing cooking equipment

If equipment primarily produces heat or moisture without grease, it may instead fall into a Type II hood application.

This can include certain:

• Dishwashers
• Steam equipment
• Light-duty non-grease-producing appliances

Equipment such as commercial refrigeration, work tables, mixers, and most cold food-preparation equipment generally does not need a cooking hood simply because it is located in a restaurant kitchen.

Most importantly, do not decide hood requirements based only on whether equipment is gas or electric. What the appliance cooks and the emissions it produces matter considerably.

If you are opening or remodeling a restaurant, plan the cook line before purchasing the hood or finalizing major cooking equipment.
