Indoor & Built-In Pizza Ovens: What to Know Before You Install One

An indoor pizza oven can become the centerpiece of a kitchen, entertaining space, or commercial cooking environment. But choosing an oven for an indoor installation requires more than finding a model that fits the available space.

With Chicago Brick Oven, indoor suitability depends on the specific oven model and its certification. CBO offers wood-fired models certified for residential and commercial indoor or outdoor use, while its residential hybrid ovens are designed for outdoor use and its commercial hybrid ovens are certified for commercial indoor or outdoor applications.

This guide explains how to choose an indoor or built-in Chicago Brick Oven, what to consider when planning the installation, and how different CBO oven models compare.

Can You Install a Pizza Oven Indoors?

Yes, Chicago Brick Oven offers pizza ovens that are certified for indoor use, but the certification is specific to each model.

CBO has several wood-fired models including the CBO 500 Countertop, CBO 750 Countertop, CBO 500 DIY Kit, CBO 750 DIY Kit, and CBO 1000 DIY Kit as certified for residential and commercial indoor or outdoor use.

The hybrid lineup is different. The CBO 750 Hybrid Countertop Residential is certified for residential outdoor use only.

So, the first step in planning an indoor installation is simple:

“Choose the exact CBO model and verify its certification before designing the installation around it.”

What Is an Indoor or Built-In Pizza Oven?

An indoor pizza oven is installed inside an enclosed residential or commercial space rather than in an open outdoor kitchen or patio.

A built-in pizza oven refers to how the oven is incorporated into its surroundings. It may be integrated into a custom masonry structure, cabinetry system, or another purpose-designed enclosure.

The terms are related, but they do not mean exactly the same thing. An oven can be designed for indoor use without every possible enclosure or installation method automatically being suitable.

The oven's:

• Certification
• Dimensions
• Required clearances
• Chimney or venting arrangement
• Support structure
• Surrounding materials
• Installation environment

all need to be considered when planning the project.

Can You Install a Wood-Fired Pizza Oven Indoors?

Yes. CBO has several wood-fired ovens which are certified for residential and commercial indoor or outdoor use. These include the CBO 500 Countertop, CBO 750 Countertop, CBO 500 DIY Kit, CBO 750 DIY Kit, and CBO 1000 DIY Kit.

Wood-fired ovens produce combustion products, so an indoor installation needs to be planned around the appropriate chimney, flue, or other required venting system for the specific oven and installation.

For example, the CBO 500 and CBO 750 Countertop models are supplied with a Class A double-wall chimney, while the DIY kits provide the oven and installation components for a custom-built enclosure.

Before construction begins, confirm:

• The exact CBO oven model
• The model's current certification
• Required clearances
• Chimney or flue requirements
• Enclosure and surrounding-material requirements
• Applicable local building and fire requirements
• Any required permits or inspections

Do not assume that an existing fireplace chimney, kitchen exhaust system, or other venting system is automatically suitable for a CBO oven.

What About CBO Hybrid Pizza Ovens?

CBO's hybrid ovens combine gas and wood-fired cooking, but the residential and commercial versions have different certifications.

CBO 750 Hybrid Countertop Residential

The CBO 750 Hybrid Countertop Residential combines a two-burner gas system with wood-fired cooking.

However, CBO residential hybrid ovens are for outdoor use only. The model is certified for residential outdoor applications.

CBO 750 Hybrid Countertop Commercial

The CBO 750 Hybrid Countertop Commercial also combines gas and wood-fired cooking, with a two-burner gas system.

Unlike the Residential model, the Commercial Hybrid is certified for commercial indoor or outdoor use.

The Commercial Hybrid is available in Natural Gas (NG) or Propane Gas (LP), and the gas type must be designated when ordering because the unit cannot be retrofitted in the field.

The Key Difference

Always confirm the current product certification and installation requirements before beginning a project.

Ventilation, Chimney and Clearance Requirements

Indoor pizza oven installation should be planned around the requirements of the specific oven rather than a generic ventilation setup.

Chimney and Flue Requirements

Wood-fired cooking produces combustion products that need to be properly managed.

CBO's countertop wood-fired models include chimney components as part of the oven configuration. The CBO 500 and CBO 750 Countertop models, for example, include a Class A double-wall chimney.

For DIY installations, the chimney or flue system should be selected and installed according to the applicable product documentation and local requirements.

Commercial Hybrid Ventilation

The CBO 750 Hybrid Countertop Commercial is certified for commercial indoor or outdoor use.

For an indoor commercial installation, the CBO Hybrid oven must use a commercial ventilation system meeting NFPA 96 or UL 710, along with applicable local building, fire and mechanical requirements.

Clearance From Combustible Materials

Clearance is another important consideration.

There is no single clearance figure that should automatically be applied to every CBO oven. Requirements depend on the specific model and installation.

Before finalizing cabinetry, masonry, walls, or other surrounding structures, confirm the exact clearance requirements for the oven you are installing.

What Should You Consider Before Building an Indoor Pizza Oven?

1. Choose the Oven Model First

Start with the exact oven model rather than designing the enclosure first.

A CBO 750 Countertop and CBO 750 Hybrid Countertop Residential may have similar size references, but they are different products with different certifications.

2. Confirm the Certification

Verify that the specific model is certified for your intended residential or commercial application.

This is particularly important when comparing CBO’s Residential and Commercial Hybrid models.

3. Determine the Cooking Surface You Need

Consider how much food you expect to cook at one time.

The CBO 500 provides a 27" x 22" cooking surface, while the CBO 750 provides 38" x 28". The CBO 1000 DIY Kit increases the cooking surface to 53" x 39".

4. Decide Between Countertop and DIY

A countertop oven arrives preassembled, while a DIY kit allows you to create a more customized enclosure.

The CBO 750 DIY Kit, for example, can be incorporated into a custom indoor or outdoor design.

5. Plan the Chimney or Venting System

Determine the appropriate chimney, flue, or ventilation requirements before construction begins.

6. Check Clearances

Make sure the planned installation provides the required clearances around the oven and uses appropriate surrounding materials.

7. Check Local Requirements

Residential and commercial projects may have different building, fire, and mechanical requirements.

Check the applicable local requirements before beginning installation.

8. Involve a Qualified Professional When Needed

For complex installations involving structural modifications, chimney or flue routing, commercial ventilation, or major remodeling, involve the appropriate professional early in the planning process.

Indoor Pizza Oven Installation: A Simple Planning Process

A successful installation starts with planning in the right order.

Step 1: Select the Exact CBO Model

Identify the exact model you want to install.

Step 2: Verify Its Certification

Confirm that the model is certified for your intended indoor residential or commercial application.

Step 3: Review the Product Specifications

Check dimensions, cooking surface, chimney or venting components, clearances, and installation requirements.

Step 4: Design the Enclosure

Once the oven requirements are confirmed, design the surrounding masonry, cabinetry, countertop, or other structure around the oven.

Step 5: Plan Ventilation or Chimney Routing

Determine how combustion products will be safely managed according to the product requirements and applicable codes.

Step 6: Confirm Local Requirements

Check whether your project requires permits, inspections, or professional installation.

Step 7: Complete the Installation

Follow the product's installation instructions and applicable requirements before operating the oven.

Indoor Pizza Ovens: Pros and Cons

Expert Tip: Choose the Oven Before the Enclosure

One of the most important decisions when planning an indoor CBO installation is to select the oven before finalizing the surrounding structure.

A useful planning sequence is:

Oven Model → Certification → Specifications → Clearances → Chimney/Venting → Enclosure → Installation

This approach helps reduce the risk of designing a finished space around an oven that is not certified for the intended application.

It also prevents confusion between similarly named CBO products with different configurations and certifications.
