Burner Tube Kit 85662

Removed cooking grates
Remove Flavor Bars
Pull off control knobs, remove 2 phillips head screws either side of the control panel. Lift off control panel.
Remove vertical face plate .
Remove large phillips head screws either side of the manifold cross member. ( holds the manifold and gas valves in place)
Slide ... Read more the cross member away from the cooking box an inch or two.
You should be able to remove each burner and access each ignition box.
Replace ignition boxes by sliding the igniter into the box, then the from
inside push ignitor box tabs through the two holes, large tab through large hole, small tab through small hole, then gently bend the small tab to 90 degrees to secure it to the box.
Install burners one at a time. Pay attention to orientation as each pair of burners has a right and left burner, plus a cross pipe. This should go back together very logically, simple.
Place manifold back over all gas nozzles and align screw holes. I put a little anti-seize on the screws when replacing. Tighten screws.
Replace vertical face plate, then control panel, then push knobs back on.
I suggest you do a short test fire before replacing the flavor bars and grates.
