Converting a Wolf Range to Propane — What Changes, and What Goes Wrong

Yes, these ranges are designed to be converted, and the conversion kit is supplied by the manufacturer. It means changing the burner orifices, adjusting the low-flame settings on each valve, and setting the regulator — not flipping a switch. A conversion done badly is closest to correct at full output and worst at simmer, so a range that has never simmered well since installation is usually a conversion problem rather than a problem that developed.

What a conversion actually is

Three things, and none of them is a setting:

  1. The orifices. Each burner has a small brass jet sized for the gas it is burning. Propane is delivered at higher pressure and carries more energy per unit of volume, so its orifices are smaller. Every burner gets a different one — they are not all the same size.
  2. The low-flame adjustment. Each valve has a screw that sets the minimum flame. It is adjusted with the flame in front of you, burner by burner, until the low setting is stable and will not blow out.
  3. The regulator. Set for the fuel actually being supplied.

On an all-gas range the oven and broil burners have their own orifices and they are part of the job. On a dual fuel range the oven is electric and only the cooktop is involved.

Why the low end is where a bad conversion shows

Three causes of clicking, in the order they occur Clicking that carries on after a burner has lit comes from three places, all under the cap. Moisture around the ceramic electrode is by far the commonest and clears itself once dried. A cap set back a millimeter out of its recess keeps the flame away from where the sensor expects it. Debris in the ports is the third. Only after those three is it the module or the switch.

Everything off and cold before anything is lifted. If a clean or a boil-over came first, dry it and give it a full day — the ceramic holds water longer than the surface suggests.

A burner running at full output is fairly forgiving: there is plenty of gas and plenty of air, and a slightly wrong orifice still produces a flame that looks acceptable. At simmer there is almost no margin. The flame lifts, goes yellow, or goes out.

That is why the complaint is nearly always "it will not simmer" rather than "it will not light", and why the simmer page sends people here.

Yellow flame on every burner is the signature. One burner burning yellow is a blocked port on that burner. All of them burning yellow, together, is the fuel setup.

The other tell: it has always been like this

A range that has never simmered well since the day it went in did not develop a problem. It arrived with one. That distinction matters because it changes what is being fixed and it usually means nothing has failed at all.

Ask yourself whether there was ever a period when it worked properly. If the honest answer is no, this page is more likely to be your page than any of the repair pages.

Going the other way

Converting from propane to natural gas is the same job in reverse, with larger orifices. It comes up when a house moves from a tank to a mains supply, and the symptoms of getting it wrong are the opposite: lazy, oversized flames and sooting.

When to call

A range whose flames are yellow across every burner, one that will not hold a simmer anywhere, or one that is about to be moved between a propane and a natural gas supply.

Tell us which fuel is being supplied now, which the range was set up for, and whether the manufacturer's conversion kit was used. What installation and conversion work involves.

If it turns out to be a repair

Every job on this site is priced the same way: an on-site diagnostic first, the figure agreed in writing before anybody starts.

  • Two burners alight at a low setting on a dark gas hob, blue flames reflected in the surface
    Low flame is a real specification

    Burner will not simmer

    The burner works, but it will not hold a genuine low flame — it either goes out at the bottom of the dial or sits too high to melt chocolate. On professional equipment this is a specification rather than a preference.

    • Flame goes out at the lowest setting
    • Nothing between "off" and "too hot"
    • A simmer that used to work and does not
    What it usually means
  • A gas burner with its cap lifted off, the spreader and igniter electrode exposed
    Cap first, igniter second

    Burner clicks and will not light

    One burner sparks and sparks and never catches while the others are perfect. The gas half of this appliance publishes no codes at all, so this page carries the whole diagnosis — and the first step is free.

    • One burner clicking with no flame
    • A burner that lights and goes straight out
    • Clicking that carries on after the flame is up
    What it usually means
  • A fitter kneeling at a base unit below a gas hob, tool case open on the floor beside him

    Appliance installation

    Fitting professional cooking equipment into a finished kitchen. Most of what goes wrong with this equipment in its first year is decided on installation day, and most of it is clearance, gas and ventilation.

    • Cutout, clearance and ventilation checked first
    • Gas and orifices correct for the fuel supplied
    • Levelled, anti-tip fitted, and handed over properly
    What this involves
  • A wide professional gas range in a home kitchen, cast-iron grates and a row of metal control knobs

    Ranges

    The appliance the brand is built around, and on a dual fuel range it is two appliances sharing one cabinet: gas burners on top, an electric oven underneath, one control answering for both. Which half is misbehaving is the first question, because the two have almost nothing in common inside.

    • A burner that clicks and never lights
    • The oven not reaching or holding temperature
    • A four-character code on the panel after a power cut

Questions people ask about this

Can I do it myself?

We would not recommend it, and in many jurisdictions the gas connection has to be made by somebody licensed anyway. The orifice change is mechanical; the low-flame adjustment on each valve is done with a flame in front of you, burner by burner, and that is the part people skip.

How do I know it was done wrong?

Yellow flames on every burner at once, and a simmer that will not hold. One burner behaving badly is that burner; all of them behaving badly the same way is the fuel setup.

It has been like that since installation.

Then it never developed — it arrived. That is genuinely good news, because it is correctable and nothing has failed.

Does the oven need converting too?

On an all-gas range, yes — the oven and broil burners have their own orifices. On a dual fuel range the oven is electric and only the cooktop is affected.

Does converting affect the warranty?

Using the manufacturer's own kit, fitted correctly, is the intended path. Improvised orifices are not, and that is worth knowing before somebody drills anything.
