WARNING: Risk of Fire or Explosion.
Follow this or an equivalent checkout procedure
after installation. Before leaving the installation,
verify that the gas valve functions properly and that
the system has no gas leaks. Gas leaks can lead to
an explosion or fire, and may result in severe
personal injury or death.
Make sure all components are functioning properly by
performing the following test:
1. Test all joints and connections for leaks with a
soap solution.
2. Close the main upstream shutoff valve and wait at
leat 5 minutes for unburned gas to escape from
the appliance, and then reopen the shutoff valve.
3. Turn on the main electrical power switch and close
the thermostate contacts. The appliance should
operate in accordance with the manufacturere’s
specified sequence of operation.
4. Turn the thermostat to a low dial setting to open
the contacts. All burner flames should be
extinguished. Repeat Steps 3 and 4 at least three
times.
5. Return the thermostat to a normal setting before
leaving the installation.
Regulator Adjustment
IMPORTANT: All adjustments must be made in
conjunction with the gas appliance and in
accordance with the appliance manufacturer’s
instructions. Only authorized personnel should make
adjustments.
!
WARNING: Risk of Fire or Explosion.
The minimum flow rate of the valve must not be
adjusted below the minimum safe working rate of the
appliance. This may cause gas leaks, which can
lead to an explosion or fire and may result in severe
personal injury or death.
The G960 can have a bottom adjust, right or let-
handed top adjust spring pressure regulator. Right or
left-hand orientation is determined by the position of
the adjustment when looking into the inlet connection
of the valve.
The regulator controls the gas pressure at the valve
outlet by positioning the regulator poppet for selected
throughput flow and pressure. This is achieved by the
valve outlet pressure acting on the regulator
diaphragm, which balances against the preset
regulator spring. Adjustment of the spring compression
determines the valve outlet pressure and the
throughput flow rate.
To adjust the outlet pressure, remove the leak-limiting
seal cap to expose the adjusting screw (see Figure 2).
Turn the screw (using a suitable screwdriver) in a
clockwise direction to increase the pressure or in a
counterclockwise direction to decrease the pressure.
