3.
Make sure that the O-ring fits 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 con-
trol with the holes in the flange. Insert and tighten
the screws provided with the flange. See Fig. 2.
Tighten the screws to 25 inch-pounds of torque to
provide a gas-tight seal.
Fig. 2. 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.
Follow the instructions below to installing the piping, and
control. Connect the pilot tubing and wiring. Make sure
the leak test you perform on the control after completing
the installation includes 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
Location
The SV9401/SV9402/SV9403, SV9501/SV9502/SV9503,
and SV9601/SV9602 are mounted in the appliance
vestibule on the gas manifold.
IMPORTANT
Make sure the mounting location protects the
control from dripping water and excessive
humidity.
IMPORTANT
Make sure the mounting location maximum and
minimum ambient temperature are both within
the specified acceptable range.
Install Piping on Control
All piping must comply with local codes and ordinances
or with the National Fuel Gas Code (ANSI Z223.1 NFPA
No. 54), as applicable.
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 igni-
tion system control as shown in Fig. 3.
