Are you planning on adding a wood fired pizza oven to your indoor kitchen? While a residential pizza oven is a great addition for enjoying traditional cooking, you should be aware of additional considerations when installing indoors.

Every indoor pizza oven installation will be different depending on your residence structure and your geographical location so make sure that your installation complies with your local building codes. We recommend contacting your local building department or inspector for requirements specific to your area before purchasing or installing your new oven. Your local inspector will be comparing your installation to your manufacturer's specification guidelines so if your oven does not come with any specifications, you may not be able to install in your home.

With that said, below are some standard guidelines and best practices when installing an indoor wood fired pizza oven.

Non-Combustible Clearances

When installing an oven indoors, it is essential to maintain appropriate clearances away from any combustible materials. A major cause of oven-related fires is a failure to maintain required clearances to combustible material.

Just to give you a reference, safe clearances for your wood-fired oven are often recommended as follows:

1. Provide at least 30" to each side, and 36" in front of the door opening.
2. Provide 18" top clearance from the top of the oven to combustible building materials.
3. Provide 10" clearance from the back of the oven to combustible building materials.
4. Provide 30" bottom clearance from the bottom of the oven to combustible building materials.
5. Install only non-combustible facade materials 6 inches to either side of and above the doorway. Generally, non-combustible cement board is used as facing material while standard drywall and sheetrock are considered a combustible and should not be used.
6. Provide non-combustible floor surface extending 36 inches in front of, and 30 inches to either side of, the door. As with any cooking equipment, we suggest choosing appropriate surfaces in front of the oven to protect the floor from potential damage from hot, heavy items that may be removed from the cooking chamber.
7. Build any non-combustible mantel above your wood fired oven using non-combustible materials.


Although these may be typical recommendations, it’s your responsibility to ensure your installation meets any building regulations and any manufacturer’s recommendations outlined in the manufacturer’s installation manual.  

Chimney Flue Clearances

The chimney flue gets extremely hot when in use so most inside installations require a UL-certified steel double wall chimney system. You should never use any combustible materials near the oven’s flue stack.

A typical recommendation is a minimum 6 inches of air space between the flue or anchor plate and any combustible material. Again, contact your local HVAC company for details, buy only products rated for this use, and check your local building department for local building codes.

Ventilation / Carbon Monoxide

Venting a wood fired pizza oven is extremely important. Carbon Monoxide is produced when fossil fuels (wood, gas, etc) burn without a good supply of air. If that happens in a room without adequate ventilation, dangerous levels of CO2 can build up. This is why having enough oxygen available for the fire and properly venting your wood-fired oven is so important.

Telltale signs of carbon monoxide emissions may include “black sooty marks” on the wall around stoves, heaters or fires, in addition to smoke accumulating in rooms due to faulty flues and ventilation.

It is always advisable to have someone familiar with gas/wood appliances to go through the installation of your oven to be sure there will be enough oxygen supply and proper venting. To monitor carbon monoxide levels, it is always a good idea to have an audible carbon monoxide detector anywhere a wood-burning appliance is used.

Pizza Oven Stand / Wall Enclosure

It is usually recommended that you construct the supporting stand from metal for interior use. Following all local codes and manufacturer’s guidelines, build the oven wall enclosure of your choice using metal studs and non-combustible wallboard.

As an extra precaution, some installers cover the oven with a fire blanket or use pourable insulation such as "certified asbestos free" vermiculite or perlite to fill any void space not requiring airspace.

Indoor Pizza Oven Installation Summary

To summarize, having a pizza oven is a great addition to your kitchen as long as you have it installed safely and conform to your local building codes.
