SV9510/SV9520 SMARTVALVE™ SYSTEM CONTROLS

5

69-2014

CAUTION

Equipment Damage Hazard.
Improper mounting location can damage 
control.

Do not mount the SmartValve™ System Control 
where water can fall on the device.

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.

Fig. 2. Sediment trap installation.

Install Control

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 
malfunction can result if the pipe is inserted too 
deeply.

Table 6. NPT Pipe Thread Length (in.)

4.

Apply a moderate amount of good quality pipe 
compound (do not use Teflon tape) only to the pipe, 
leaving two end threads bare. On LP installations, 
use a compound resistant to LP gas. See Fig. 3.

Fig. 3. Use moderate amount of pipe compound.

5.

Remove the seals over the ignition system control 
inlet and outlet, if necessary.

6.

Connect the pipe to the ignition system control inlet 
and outlet. Use a wrench on the square ends of the 
ignition system control. If a flange is used, place the 
wrench on the flange rather than on the ignition sys-
tem control. Refer to Fig. 4 and 5.
