Ignition system controls with standard or slow opening
regulators (SV9520H) can be converted from one gas to
the other with a conversion kit (ordered separately).
Order part no. 393691 to convert from natural
(manufactured) to LP gas; order part no. 394588 to
convert from LP to natural (manufactured) gas.
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.
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 resis-
tant 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, and connecting the 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 SV9520H is mounted in the appliance vestibule on
the gas manifold.
CAUTION
Equipment Damage Hazard.
Water can damage equipment and wiring.
Do not locate where water can drip on the control.
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.

CAUTION
Gas Leakage Hazard.
Failure to follow precautions can result in a gas-filled work area.
Shut off the main gas supply before removing end cap. Test for gas
leakage when installation is complete.
ALL BENDS IN METALLIC TUBING MUST BE SMOOTH.
