Propane Wolf grill fades when the temperature drops

What you are looking at

• Strong flame early in the evening and a fade by the end of it.
• It will hold a low setting and will not reach a sear any more.
• Worst on the coldest nights and fine again on a warm afternoon.

What to check yourself

1. Start with how much is left in the cylinder. A tank near the end behaves differently from a full one.
2. Make sure the cylinder valve is open all the way and the coupling was made up properly the last time the tank went back on.
3. Look over the flexible hose for cuts, cracks and wear. Wolf asks for that before each use, and the hose that wintered outdoors is the one.
4. Give it a wind block if the patio is open. Where wind is taking the flame, Wolf says shelter the grill rather than touch the burner.

If you can smell gas, stop. Shut the supply off at the grill, put out any flame, open the hood, and move away before you call your gas utility or the fire department from outside. That call comes before this one, and it is not a call for an appliance shop.

What happens on the visit

1. Inlet pressure taken under load and set against the propane figures Wolf publishes: ten inches of water column at the appliance, eleven as the minimum in the line.
2. The regulator and hose supplied with the grill, and the coupling at the cylinder, where cold and handling both land.
3. The burners and their ports afterwards, so a grill starved on the supply side is never treated as a dirty one.
