Control Valves
The control valves
supply and regulate the gas flow to the burner. These valves have a spring
loaded locking feature and are designed to lock into place when the valve
is in the OFF position. The valve must be depressed by pushing in the control
knob while turning to the ON position. If a problem occurs with the valve
lock not releasing, check that the valve stem extends sufficiently from
the control panel and is allowing full depression of the control knob which
releases the locking device.
- Repair parts - Individual repair
parts for control valves are not available. Replacement is necessary
if a control valve becomes broken or frozen and replacements for some
models are available individually or may occasionally require replacement
as a set. Valve configuration varies widely between makes and models
of gas grills and must be ordered specifically for your make and model
of grill.
- Orifice cleaning - The valve orifice
is an integral part of the control valve. Orifices on the valves will
sometimes plug from either insects invading through the venturi or from
debris inside the supply line. Orifices can be removed for cleaning.
Use an orifice cleaning tool or small wire to clear orifice hole. Use
caution not to scratch or damage the orifice hole. Do not operate
grill without orifice in place. This poses an extremely dangerous fire
hazard.
- Orifice size - The orifice, in
conjunction with the control valve, acts to regulate and restrict
the amount of gas delivered to the burner. The hole size in the orifice
varies by the gas supply pressure and by the BTU rating of the burner.
Grills equipped for LP gas operate at a much higher gas pressure and
therefore have a smaller size orifice.
- Conversion kits - Conversion kits
are available for changing the grill gas supply from propane to natural
gas for some brands of grills. Generally included in the kit are proper
sized orifices and a flexible hose and quick connect assembly.
- Knobs - Control knobs vary greatly
between grill brands. The variances are the knob shaft length, clockwise
and counter clockwise bezel, and the OFF position. Original equipment
knobs grarantee a proper fit and indication. In addition, universal
replacement knobs are available that can be set up for most brand grills.
NOTE:
The information provided is not intended to take the place of the
owners manual that was supplied with your grill. Specific safety,
repair and maintenance information varies between grill models and
brands. Always refer to your owners manual first.
