An indoor pizza oven is a novel and fun addition to your home. A true indoor pizza oven that runs on propane is difficult to manage, as it can be dangerous indoors. Even the tiniest of leaks can lead to a life-threatening explosion. If you decide to build an indoor pizza oven, it is suggested to build a wooden one, rather than a propane one. However, the decision is up to you. It will take some time to build your own indoor pizza oven, however, new pizza oven kits make the job much easier than ever before.

  1. 1

    Choose whether you want a precast refractory oven or a brick oven. A precast oven is the more economical choice, and is available in many sizes to fit different spaces and needs. A brick oven is perfect for the connoisseur home chef. Brick ovens are usually artisan made, and each design has its own characteristics. Many brick ovens are now modular in design, and can be built to accommodate a site specific hearth/stand or one designed especially for the oven. A precast oven is 50 per cent less in total cost than a brick oven, although the installation costs for both types are about the same. You will need to choose a pizza oven kit that has a propane run bottom grill rather than a standard solid cement one that would be used for a wood fire oven. If you cannot find the type of grill you like with the type of oven you like, order an outdoor propane pizza oven grill, and get the brick oven made to order.

  2. 2

    Measure the available space you have and compare it with the size of the available oven kits. Decide on the size of the oven, as well as the shape of the oven's opening. The size of your oven will determine how many items you can cook at once. The landing size (oven bottom and stand) required by the oven changes depending on the overall size of the oven. Drill a hole in one of the nearest walls, close to where the propane line attachment for the pizza oven is the closest.

  3. 3

    Install the oven stand and the back cement heat wall at the appropriate distances. The cement heat wall should be close to the back of the pizza oven so that it will protect the wall from the excess heat of the oven. The oven stand should be at least 30 to 36 inches away from the ground and surrounding walls. Attach the oven dome of your choice, based on whether you would like a precast or brick oven. Adjust the placement of the oven so that the vent opening in the dome lines up well with either the chimney flue, or a ventilation airway.

  4. 4

    Attach a ventilation pipe from the pizza oven vent opening to the exit opening in the house. This can either be created especially for the pizza oven, or be a pre-existing opening, such as a chimney. Make sure that the ventilation pipe is well secured and will not leak smoke. Do this by attaching and adjusting an o-ring with a flat head screwdriver. Do this on both ends of the pipe until it is snug.

  5. 5

    Run the propane line through the hole in the wall that you drilled after joining it to the attachment of the pizza oven grill. Attach the other end of the hose to the propane tank. It is safer to have the propane tank in a separate room from the grill. Confirm that the hoses are tightly and completely attached, and that there are no leaks. Attach any accessories or covers for your pizza oven. Often, oven kits come with a brick arch in a design of your own choosing, or you can choose to build your own arch from brick or stone.

Tips and warnings

  • Attempting to install a pizza oven indoors on your own is a dangerous activity if you do not have much previous experience in home repairs. If you are new to this, it is best to seek the advice of a professional installer. Your point of purchase for your pizza kit will be able to recommend a reputable installer in your area.
  • Having an indoor propane pizza oven is more dangerous than having a wood fire pizza oven. Even a small leak can result in an explosion. Make sure there are no leaks in your hose, your propane tank, and that the ends of the hose are firmly attached to the tank and the oven. It is strongly suggested to have a wood fire pizza stove rather than a propane one.
