Reference the Itron Gas Endpoint Meter Compatibility List (PUB-0117-002 or the 2.4GZ

OpenWay Remote Mount Gas Module Meter Compatibility List on page 3 for compatible

diaphragm meters.

Tools and Materials Supplied By You

Note 2.4GZ OpenWay Remote Mount Gas Module installation to a diaphragm
meter may require additional tools and materials over those listed in Installation

Prerequisites on page 7.

The following user/installer-supplied tools and materials are required to install, program,
and check the 2.4GZ OpenWay Remote Mount Gas Module:

• Medium flat-blade screwdriver for band clamps.

• Medium flat-blade, torque-measuring screwdriver for screws to attach adapter plates

to pipe brackets and screws to attach endpoints to adapter plates. (Use torque
measured 9 to 12 inch-pounds.)

• Medium Philips screwdriver to attach endpoints to flat surfaces

• Pliers to secure cable ties.

• Side-cutting pliers or similar tool for removing excess cable tie ends.

• 1/4" nut driver or other blunt tool for seating endpoint tamper seals.

• FC200SR handheld with Endpoint-Link or Endpoint-Link Pro (version 5.3 or higher)

for programming and checking endpoints.

• 1" putty knife or similar tool to remove old gasket material from the meter and index

Installing the 2.4GZ OpenWay Remote Mount Gas Module

The 2.4GZ OpenWay Remote Mount Gas Module mounts on a pipe using the Remote
Mount Installation Kit (Itron part number CFG-0005-003) or a vertical flat (wall) surface.
Always mount the 2.4GZ OpenWay Remote Mount Gas Module with the printed label
right-side-up (arrow pointing up -1), and the encoder wires (2) and tamper seals (3) at the
bottom, as shown.

Caution Upright vertical positioning is ver y im portant becaus e:

• 2.4GZ OpenWay Remote Mount Gas Module are designed with the
antenna in a vertical direction so the antenna is parallel to the
reading device (which has a vertical antenna). Matching antenna
polarity can greatly affect RF performance and enable easy module
reading.

• 2.4GZ OpenWay Remote Mount Gas Module are designed so the
tilt tamper is vertical. It is important to maintain vertical positioning in
the field to enable tilt tamper stability.

Encoders

Caution To insure proper adhesion, the 2.4GZ OpenWay Remote Mount Gas

Module encoder must be installed at temperatures between 40° to 95° Fahrenheit.

There are tasks when installing the 2.4GZ OpenWay Remote Mount Gas Module with an
encoder on a diaphragm meter:

• Remove the index cover and any gasket residue

• Install the 2.4GZ OpenWay Remote Mount Gas Module encoder on the index

• Program the 2.4GZ OpenWay Remote Mount Gas Module

• Attach the index cover to the meter.

To remove the index

Note Properly dispose all unused screws, old index c ov ers, gaskets, tamper seals,
and other leftover materials. Do not leave materials on customer premises.
Replace any stripped, worn, or corroded mounting screws.

1. Cut and remove any wire seal routed through the index cover screws. Remove the
index cover and set aside. Remove the index mounting screws in an alternating
fashion.

Chapter 5 Diaphragm Meter Installation

2. Remove the two index screws in an alternating fashion. Loosen the left index screw
two turns, loosen the index screw three to four turns. Hold the index while removing
the screws to keep the index from falling. Set the index aside where it will not be
damaged.

3. Remove old gasket and any gasket residue from the meter and index cover.

4. Use the FC200SR to read the 2.4GZ OpenWay Remote Mount Gas Module and

record the reading for comparison with progressive readings as installation is
completed.

To install the encoder

1. Take the magnet hub from the Encoder Installation kit (Itron part number CFG-0081-

001).

2. Verify there is only one magnet in the hub.

NOTE If there is no magnet or if there are two magnets in the magnet hub,

discard the magnet hub and use a hub with one magnet.

ng is not higher than the previous reading, the 2.4GZ OpenWay

3. Briefly place the magnet side of the magnet hub into the curved indentation in the
encoder, as shown.

4. Take the magnet hub away from the encoder and set it at least one inch away from the
encoder.

5. Use the FC200SR to read the 2.4GZ OpenWay Remote Mount Gas Module. If this
reading is higher than the reading taken after removing the index, the 2.4GZ
OpenWay Remote Mount Gas Module is counting and working properly.

NOTE If the readi
Remote Mount Gas Module is not reading. Repeat steps 3, 4, and 5. If the 2.4GZ
OpenWay Remote Mount Gas Module is still not counting, replace the 2.4GZ
OpenWay Remote Mount Gas Module and perform steps 3, 4, and 5.

6. Align the large notch in the side of the magnet hub spacer with the needle of the meter
drive rate dial (1 foot or 2 foot for residential diaphragm meters; 5, 10, or 100-foot for
commercial diaphragm meters).

7. Press the magnet hub spacer down over the dial needle as far as possible. The tip on
the bottom of the spacer may touch index face. Turn the dial after hub spacer
installation to verify the index dial functions with a smooth, easy rotation.

8. Align the pointer (1) on the top of the magnet hub and the notch (2) in the side of the
magnet hub with the needle (3) of the meter drive rate dial.

9. Press the magnet hub down over the hub spacer as far as possible. The bottom of the
hub spacer may touch the index face. Turn the dial after magnet hub installation to
verify the index dial functions with a smooth, easy rotation.

10. If the tip of the dial needle sticks out past the edge of the magnet hub, cut off the end
of the dial needle as close as possible to the magnet hub with a sharp, side-cutting
pliers.

11. Take the alcohol-saturated cleaning pad from the Remote Encoder Installation Kit
(Itron part number CFG-0081-001).

12. Select a location on the index face next to the magnet hub. After encoder installation,
the encoder cable must not interfere with the index dials.

Note If a TEMP COMP sticker is attached to the index where the encoder
cable will mount, remove it before priming. If the sticker (or replacement
sticker) must be put back on the register face, place it in a new location on
the index face after the encoder is attached.
