URNERS

The infra-red burners require no air adjustment after they have left the factory. If a major change in burner operation is
noticed, check for obstruction of airflow, around the orifice. Burner performance is affected by (a) orifice size, (b)
pressure, (c) injection, and (d) primary airflow. The burner orifice must be centered within the air mixer opening.

EGULATOR

The pressure regulator is located in the right-hand interior compartment of the broiler. Accessing it will require
removing the front panel and the right side panel of the broiler. The regulator is preset for 4" W.C. for natural gas, or
10" W.C. for propane gas. If adjustment is necessary, do the following:

1. Turn broiler control knob to OFF.

2. Attach a pressure-measuring device to the 1/8" NPT connector located on the front of each burner manifold.

3. Turn the broiler control knob to HIGH and, with the burners lit, check the manifold pressure. The pressure should

be 4" W.C. (for natural gas) or 10" W.C. (for propane gas).

4. If necessary, adjust the pressure by unscrewing the top of the pressure regulator (use a screwdriver) to expose

the adjustment screw underneath. Rotating the adjustment screw clockwise increases the manifold pressure.

5. After the pressure has been adjusted, turn the broiler control knob to OFF, replace the top of the pressure

regulator, and disconnect the pressure-measuring device (replacing the plug into the connector on the manifold).
