Rotation

a) Check to see if either the knob or the

valve stem is rubbing the control panel.

If so, align the manifold pipe before

replacing the valve. If the alignment is

good, replace the valve.

Note: Any type of side pressure on the valve stem will cause the valve to leak.

Description

The top burner gas valves control the gas flow to the top burners. The valve is a barrel and core, grease sealed, locking type valve. Be- fore the stem can be turned, it must be pushed in to unlock the valve. The valve is made up of a hollow core, pressed into the barrel of the valve by a spring, and sealed with grease. Gas flows from the manifold pipe into the rear of the valve and enters into the hollow core. The core has one large and two small holes in its side. When the stem of the valve is rotated, the core rotates with it. As the core is rotated, gas is allowed to flow from the large hole into the mixer elbow.

When the core is rotated 90-angular degrees, the large hole in the core matches the hole in the barrel allowing the maximum amount of gas to flow. When the core is rotated past 90˚, the gas flow is reduced. When the core is rotated the full 210˚, the two small holes are aligned with the hole in the barrel, and the only path for gas to flow from the core, is through the two small holes. The amount of gas that flows through the two small holes, called the minimum flame, is controlled by an adjust- ment screw, located in the center of the valve stem. The adjustment of the minimum flame should be made at the time the range is in- stalled.

2.The valve stem is hard to turn, or cannot be turned.

a)Check to see if the control panel is preventing the stem from being pushed in. If so, adjust the manifold pipe. If not, replace the valve.

3.Valve lock release has failed.

a)Replace the valve.

4.Valve is not greased.

a)Replace the valve.

5.Minimum flame too high.

a)Make a minimum flame adjustment.

6.Burner flame goes out when valve stem is fully rotated.

a)Make a minimum flame adjustment.
