Earthstone’s 90-PA Wood Fired Pre-Assembled Oven is their most popular free-standing residential model. With a 35″ cooking diameter interior and a 20″ wide by 9.5″ high oven entrance, it’s big enough to do three to four 8″ pizzas or two to three 12″ pizzas. It is also available as a gas model or combo gas and wood model.
The oven body parts are a cast 4 to 6 inch thick, high temperature refractory material. The steel support frame and enclosure are constructed of heavy gauge welded tube steel and angle iron. The void area between the cast oven body and steel circular enclosure is filled with a hardened lightweight insulation mixture. This combination of cast refractory body and outer insulation shell is designed to maximize thermal mass or heat storage capacity, and reduce temperature fluctuations. Total weight is 2500 pounds.
The exterior is gray powder coated steel. Most owners elect to install 90-PAs inside a more attractive, decorative outdoor kitchen setting.
The hearth floor tiles are composed of kiln fired refractory material. The cooking oven body and floor tiles are cast and assembled individually to reduce the possibility of stress cracks due to normal heat expansion and contraction and allow for easier replacement.
An Infrared Gun is useful to accurately check floor and dome temps. The cast aluminum door has Teflon handles. Your choice of a stainless steel or copper hood cover is included, along with a stainless flue adaptor and pizza peel.
The Model 90-PA is U.L. listed for installation with a 1-inch side clearance to combustible materials.
Earthstone Ovens was founded in 1987 by Maurice Sabbagh Yotnegparian, a car mechanic who relocated from France to California in the 1950s. An avid cook, Yotnegparian found time to explore culinary pleasures while pursuing his craft restoring luxury cars in the Los Angeles area. He became friends with several French chefs in LA and built a pizza oven at his home. Eventually he began importing and selling ovens from France. The initial success of this venture led him to design and build his own ovens. Today Earthstone produces a large selection of residential and commercial ovens and accessories.
Because much of their business is commercial, all components must be food grade. All ovens are manufactured in California and are UL and ULC listed backed with a five year limited warranty. Earthstone is still owned and operated by the Yotnegparian family.

The amazing Karubecue is the most innovative smoker in the world. The quality of meat from this machine is astonishing. At its crux is a patented firebox that burns logs above the cooking chamber and sucks heat and extremely clean blue smoke into the thermostat controlled oven. It is our favorite smoker, period.

This is the first propane smoker with a thermostat, making this baby foolproof. Set ThermoTemp’s dial from 175° to 350°F and the thermostat inside will adjust the burner just like an indoor kitchen oven. All you need to do is add wood to the tray above the burner to start smokin’.
