SV9540; SV9640 SmartValve™ SYSTEM CONTROLS
Install Adapters To Control
If adapters are being installed on the control, mount them
as follows:
Flanges
1. Choose the appropriate flange for your application.
2. Remove the seal over the ignition system control
inlet or outlet.
3. Make sure that the O-ring is fitted in the groove of
the flange. If the O-ring is not attached or missing,
do not use the flange.
4. With the O-ring facing the ignition system control,
align the screw holes on the ignition system control
with the holes in the flange. Insert and tighten the
screws provided with the flange. See Fig. 1. Tighten
the screws to 25 inch-pounds of torque to provide a
gas-tight seal.
1 DO NOT USE FLANGES ON 3/4 IN. INLET
AND 3/4 IN. OUTLET MODELS, AND ON
THE 3/4 IN. OUTLET SIDE OF 1/2 IN.
INLET AND 3/4 IN. OUTLET MODELS.
Fig. 1. Firmly fasten flange to valve,
but do not overtighten screws.
Bushings
1. Remove the seal over the ignition system control
inlet or outlet.
2. Apply a moderate amount of good quality pipe
compound to the bushing, leaving two end threads
bare. On an LP installation, use compound resistant
to LP gas. Do not use Teflon tape.
3. Insert the bushing in the ignition system control and
carefully thread the pipe into the bushing until tight.
Complete the instructions below for installing the piping,
installing the control, connecting the pilot tubing and wiring.
Make sure the leak test you perform on the control after
completing the installation includes leak testing the
adapters and screws. If you use a wrench on the valve
after the flanges are installed, use the wrench only on the
flange, not on the control. See Fig. 5.
Location
The SV9540; SV9640 are mounted in the appliance
vestibule on the gas manifold.
IMPORTANT
These ignition system controls are shipped with
protective seals over the inlet and outlet tappings.
Do not remove the seals until ready to connect
the piping.

Install Piping to Control
All piping must comply with local codes and ordinances or
with the National Fuel Gas Code (ANSI Z223.1 NFPA No.
54), whichever applies. Tubing installation must comply
with approved standards and practices.

1. Use new, properly reamed pipe free from chips. If
tubing is used, make sure the ends are square,
deburred and clean. All tubing bends must be
smooth and without deformation.
2. Run pipe or tubing to the ignition system control. If
tubing is used, obtain a tube-to-pipe coupling to
connect the tubing to the ignition system control.
3. Install a sediment trap in the supply line to the
ignition system control. See Fig. 2.

1. This ignition system control can be mounted 0 to
90 degrees in any direction, including vertically,
from the upright position of the ignition system
control switch.
2. Mount the control so the gas flow is in the direction
of the arrow on the bottom of the ignition system
control.
3. Thread the pipe the amount shown in Table 6 for
insertion into ignition system control or adapters. Do
not thread pipe too far. Valve distortion or malfunc-
tion can result if the pipe is inserted too deeply.
