Gas supply to the burners · Rose Hill
Wolf Range Pressure Regulator
The pressure regulator holds the gas feeding a Wolf range's burners at one steady pressure, however the house line varies. Wolf builds it into the range, and its installation notes ask for the range to be connected to a gas supply that is already regulated.

What We Usually Find · Rose Hill
- Most often
A second regulator fitted outside the range at installation. The range already carries its own, and Wolf's checklist for a weak or uneven flame asks for an added one to be ruled out.
- Sometimes
Supply pressure that is wrong for the range: too low when the house line struggles to feed several gas appliances at once, or too high. Wolf names both as causes of a poor flame.
- Rarely
The range's own regulator. Wolf lists a faulty or damaged regulator among the causes of weak flame and poor ignition, but it is the last part we condemn, after the supply has been measured.
What it means for the repair
We check the pressure arriving at the range and what the range passes on to its burners. That splits the answer three ways. A fault inside the range, in its own regulator or anything after it, is ours to repair. An added regulator or a supply problem belongs to the house: work on the gas line goes to a gas fitter, and we tell you which of the two it is and what pointed there.
Before you call
Light each burner on Hi in turn and note which look weak. If they all do, note whether other gas appliances in the house were running at the time; a line that sags under load is a clue worth having. Leave the regulator and the gas line alone, because neither is something an owner adjusts.
In Rose Hill kitchens
Rose Hill has seen a great deal of recent building: big houses on compact lots, many of them with a wide Wolf range put in when the house went up. A range that has run weak from its first week points us at the installation, an added regulator or a gas line sized for less than the house now asks of it, rather than at anything worn.
What it costs to put right
No set band. A fault in the range's own regulator is quoted after the diagnosis, as one figure for parts and labour. An added regulator or a supply problem is house gas work: it goes to a gas fitter, who prices it.
A flat $89 pays for the visit and the whole diagnosis; approve the repair and that $89 comes off its price.
Asked about this one
Every burner on my Wolf range looks low. Is it the regulator?
Possibly, but low flame on every burner at the same moment usually starts before the burners: the supply pressure, a second regulator, or a shut-off not fully open. One weak burner points at that burner instead. Wolf Repair Kirkland, (425) 699-2400, checks what arrives at the range before any part is changed.
Can the regulator be turned up for a bigger flame?
It is not an owner adjustment, and more pressure is not a cure. Wolf lists excessive supply pressure as a cause of poor flame just as it lists too little, so the aim is the pressure the range was built for. When the flame is weak, the cause is found and put right rather than overridden.
