5. Mount the valve to the pipework. Use an approved
pipe joint sealing compound on the male threads
before assembly. Remove excess compound after
mounting the valve to the pipework. Threads of the
pipe and nipples must be smooth and free of tears
and burrs. Steam clean all piping to remove
foreign substances such as cutting oil or thread
chips. A sediment trap should also be installed in
accordance with the National Fuel Gas Code
(ANSI Z223.1).
6. 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.
7. 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.

8. 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.

9. 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.

10. Attach the thermocouple securely to the pilot
burner, and screw the terminal end to the BASO
power unit terminal on the valve. Make sure this
connection is clean. Tighten the thermocouple
lead nut finger tight, plus a maximum of 1/8 turn.
Do not overtighten.
