Change the Side Burner Orifice
1. Remove the two screws which were pre-assembled on
side burner tube, and the igniter wire from side burner
tube. Lift side burner tube out from side burner firebox,
as shown below.
2. Use 6 mm socket wrench or 6 mm nut driver to remove
the orifice. Replace with the Natural gas orifice.
IMPORTANT: Check that the orifice is properly
installed inside of the valve.
3. Reinstall the side burner. Install and tighten the two
screws and reconnect the igniter wire.
4. Open the manual shutoff valve in the gas supply. The
valve is open when the handle is parallel to the gas pipe.
5. Test all connections using an approved noncorrosive
leak- detection solution. Bubbles will show a leak.
Correct any leak found.
6. For normal operating sequence of the ignition system,
see "Lighting Instructions" on page 9.
