Direct Drive Rotisserie
Instead of utilizing a belt or chain drive to transfer power from the motor to the shaft, Wood Stone uses 1/4HP motor connected directly to the shaft. In the traditional horizontal rotisseries this eliminates the very common problem of the belt or chain failing, or the need to adjust the belt or chain.Note: the Wood Stone Vertical Spit Rotisserie does utilize a different style of drive system which incorporates a very durable belt.

Single-piece cast ceramic top to the oven.  It has a bit of an “igloo” shape.  The mass of the dome stores heat and the shape helps reflect that energy back down on the cooking surface.

The decoration put on or around the oven.  It may be as simple as adding tile to the oven directly, or as involved as an entire facade wall with extensions to the oven.  Typical facades are Tile, Brick, Stone, Stucco, etc.

Finishing Zone
Middle third of the oven from the flame where pizzas are placed for the last few minutes of cooking and other longer cooked foods are placed for a quick finish but not as direct as the “searing zone”.  This is 1 of 3 cooking zones in our ovens. Please see Searing-Saute zone and Raw Landing Zone.

The cooking surface of the oven; our preferred term is “hearth”.

Flue Collar
The exhaust collar extending from the oven which exits into the ducting or hood.  In the Mountain Series and Bistro ovens, and some Fire Decks, this can be directly connected to the venting ductwork (check with local officials) In the FD-6045 and FD-8645 it must go under a hood.

A “sticky” substance found in wheat which gives strength to flour.  Kneading can activate the gluten.  Wheat flour has different percentages of gluten; higher gluten tends to make a softer more “bready” dough while lower gluten levels in flour are part of a recipe for thinner and crisper pizza doughs.

We call the cooking surface, or floor of the oven, “the hearth”.  All Wood Stone ovens utilize a monolithic (single-piece) construction for the hearth and we use a special formula of high temperature refractory unique in the foodservice world.

Negative Air or Low Pressure Area
This is an area of the restaurant in which the air pressure is lower than the air pressure present at the oven door opening, which may affect proper oven operation when the oven is installed incorrectly. For example, this may occur in the back of the house (rear kitchen) (see venting dos and don’ts)
