6. Mount the G93 on a horizontal manifold with the
solenoid pointed up (vertical) or in a position not
exceeding 90 from vertical. The valve may also
be mounted on a vertical manifold in any position
around its axis (Figure 1).
Vertical mounting may
be 360 around it axis
with the gas flow either
up or down, but always in
the direction of the arrow.
Figure 1: G93 Mounting Positions
7. Installer must be a trained, experienced, flame
safeguard control technician. Threads of the pipe
and nipples must be smooth and free of tears and
burrs. A sediment trap should also be installed in
accordance with the National Fuel Gas Code
NFPA 54 (see Figure 4). Mount the valve to the
pipework, use a quality rated pipe tape, UL listed
seal material rated for gasoline, propane, and
other gases. If not available, a quality grade pipe
dope, a light amount on the male threads, starting
two threads away from the first engaging thread. If
pipe dope lodges on the valve seat, it will prevent
proper closure. Remove excess compound after
mounting the valve to the pipework.
8. Thread pipe (the amount shown in Table 1) for
insertion into the control. Do not thread the pipe
too far. Valve distortion or malfunction may result if
the pipe is inserted too deep.

9. For any threaded connections, threads of pipe and
nipples must be smooth and free of tears and
burrs. Steam clean all piping inside diameter to
remove foreign substances such as cutting oil or
thread chips before installing into the valve. Apply
a moderate amount of good quality pipe
compound (do not use Teflon tape) to pipe only,
leaving two end threads bare (see Figure 2). On
LP installation, use compound resistant to LP gas.

PIPE COMPOUND TO PIPE ONLY
(LEAVE TWO END THREADS BARE),

10. Connect pipe to gas control inlet and outlet. Use a
wrench on the square ends of the control. If a
flange is used, place the wrench on the flange
rather than on the control. This process should be
used for both the installation and removal of the
valve in a gas system. (see Figure 3).
APPLY WRENCH TO THE FLATS
FROM THE BOTTOM OF THE
GAS CONTROL VALVE.
