ik INSTALLATION AND MAINTENANCE INSTRUCTIONS
Installation and maintenance must be done to the Click here to view installation steps
iiirequirements of the local building code or
governing agency; or, in the absence of local building codes, to the requirements of the
National Fuel Gas Code (ANSI Z223.1), and, if applicable, the National Electrical
Code (ANSI/NFPA 70). Installation and maintenance must be performed by personnel
having the qualifications required by law to install and service natural gas lines and
equipment.
Whenever possible, the valve should be installed in the gas line before the line enters
the protected structure. Generally this is on the customer's side of the meter; but may
be upstream of the meter if allowed by the utility.
` Install valve in upright position with the gas flow in the direction of the arrow on the
valve body. The plumb chain in the level indicator on the side of the valve must be
centered in the hole in the bracket through which it passes.
C�, OP�Z Warning: If the valve is installed so the gas flow is in the direction OPPOSITE
THE ARROW on the valve body, the valve WILL NOT OPERATE

8/31/2015 Strand::Installation Instructios::Horizontal California Valves
Unless otherwise specified by code, it is recommended that the valve be inspected at
least once a year to assure it is level and has not been damaged. If the valve is found
to be out of level or appears damaged, the customer should call a qualified gas service
• person to arrange repairs.
Warning: Read the following sections before attempting to reset the valve.
OPENING&RESETTING OF THE VALVE—MODELS 300,301,302,303
When the valve is closed, a Red Bar will be visible through the window in the position
indicator, which is located on the bottom of the red bonnet,just above the clamp band.
To open the valve, first verify that the main gas shutoff valve is closed, then gently
rotate the Reset Cam(located on the side of the valve)in the direction indicated by the
"to open" arrow, until the Green Bar is visible through the window. Release the turning
effort. If reset has occurred, the Reset Cam will return to its original position, and the
Green Bar will remain visible through the window. The valve is now open, and the
acceleration trigger mechanism is set to respond to a seismic disturbance. The main
gas shutoff valve may now be opened.
OPENING&RESETTING OF THE VALVE—MODELS 310,311,312,313,314,314F,
315,315F,316,316F,317F,318,318F,&319F
When the valve is closed, a Red Bar will be visible through the window in the position
indicator, which is located on the bottom of the red bonnet,just above the clamp band.
To open the valve, first verify that the main gas shutoff valve is closed, then gently
rotate the Reset Cam(located on the side of the valve) in the direction indicated by the
"to open" arrow, which will open the pressure-release poppet in the center of the
valve's disc. Hold the Reset Cam in this position until the pressure equalizes across
the valve's disc. Then, with very little turning effort, continue rotating the Reset Cam
until the Green Bar is visible through the window. Release the turning effort. If reset
has occurred, the Reset Cam will return to its original position, and the Green Bar will
remain visible through the window. The valve is now open, and the acceleration trigger
mechanism is set to respond to a seismic disturbance. The main gas shutoff valve may
now be opened.
Warning: If the reset shaft does not return to its original position, or the valve remains
closed and will not reset, the gas service must be shut off and the valve replaced
before service can be restored. If the valve will not reset, please call the factory or
your distributor for technical service.
After an Earthquake
The acceleration trigger mechanism within the valve has been factory tested to verify
that the finished valve complies with national (ASCE 25-97) and state (California 12-
16-1) standards. Gas plumbing damage may have occurred during an earthquake or
aftershock. If a gas leak exists, gas service should be turned off at the main shut-off
valve. Do not restore the gas service without assistance from a qualified person. You
will be safer if you let authorized personnel restore service.
