Questions about this item

How do I install the Weber 67033 manifold assembly on my Spirit II 18 grill?

Turn off the LP tank and disconnect the regulator. Remove the control panel to access the old manifold. Unscrew the burner tubes from the old valves, swap the manifold, then reattach each tube securely to the new valves before reassembling the panel and leak-testing every joint with soapy water.

What maintenance or replacement will the Weber 67033 manifold assembly need over time?

Inspect the valve orifices and burner tubes each season for spider webs, grease blockage or corrosion. Clean the venturi tubes with a brush and replace the LP regulator and hose every five years or if cracking appears. The manifold body itself rarely needs replacement unless physical damage occurs.

What is the first limit that appears when the Weber 67033 manifold assembly runs under sustained high heat?

The three LP valves are rated for standard Spirit II 18 output; prolonged maximum settings can cause valve stems to stiffen from heat soak, making fine flame adjustment harder until the manifold cools.
