  1. Consult your local authorities to determine what permits are required before constructing your gas burnout oven. For the United States of America, compliance with the Clean Air Act is mandatory, and failure to comply with the act can result in severe fines and possibly jail time.
  2. Determine where the oven will be located; it should be situated close, but not too close, to an outside wall. Using form and rebar, construct a concrete pad in the location 4” deep. Ensure the pad is level and lay out the corners of the oven, placing anchor bolts into the pad.
  3. The oven box is better obtained pre-manufactured. However, if you decide to construct your own oven box, use heavy gauge steel. Pay very close attention to the quality of the weld and ensure that the tolerances at the floor and mechanical void locations are secure. Cut enough holes for the thermostat, oven venting, oven control, natural gas heat or air injection system, and the automatic oven door open shut-off mechanism.
  4. At the corners and at the 1/3 points along the top edges of the box and the roof section, weld fabric attachment clips. Place the oven box onto the concrete pad and bolt it into place with a floor jack.
  5. Hire a licensed electrician to install and wire all the oven units, including the natural gas heater, venting fans, shut-off, and thermostat units.
  6. To install the heat fabric and bricks, first, attach the heat-resistant fabric to the welded steel clips. Line the floor and walls with heat bricks, cutting the bricks only where needed, for equipment. After the final row of bricks is done, lay flat steel across the top for roof bricks.
  7. Cut a ventilation hole in the building wall and install the vent ducting to the exterior. To make connections accurately, hire the help of a trained electrician.
  8. Test the oven by slowly bringing it up to full temperature. Allow a good amount of time for a break-in before attempting a full cycle.
