E. Complete the Conversion
Step 1: Adjust the burner venturi. Loosen the screw securing the
venturi cap and adjust to the correct setting. See FIGURE 5
and TABLE 2.
Regardless of venturi orientation, closing the air shutter will
achieve a desired yellow flame, but may produce soot on the
glass. Opening the air shutter will cause a short, blue flame that
may lift off the burner.
Slight adjustments to the venturi opening will create dramatic
results. Adjust at slight increments until desired look is achieved.
Step 2: Reinstall all components previously removed in section A (pg.
3). Refer to the installation manual for more information.
Step 3: Turn the manual valve counterclockwise to the ON position.
Step 4: Reconnect electrical power.
Step 5: Check for leaks at all connections with soapy water.
