Install Igniter-Sensor Assembly
Install the ground rod, if needed. See Fig. 7.
• Mount adapter to the ground rod, if needed.
• Align the ground rod so the clip hugs the pilot burner
and keeps the ground rod from rotating. See Fig. 8.
• Insert the ground rod in place of the thermocouple
on the pilot burner. Push the ground rod all the way
up and fasten as shown in Fig. 7.
Slide the igniter-sensor mounting bracket over the top
of the ground rod.
Adjust the electrode position so the electrode tip and
spark gas are in the pilot flame. Turn the ground rod to
move the igniter-sensor up and down.
Check that the chosen position allows room to connect
the ignition cable to the stud terminal.
Tighten the setscrews on the mounting bracket using
the hex wrench provided.

To convert from natural gas to LP, use the 393691 LP
Conversion Kit that is included with the Y8610U Intermittent
Pilot Retrofit Kit. To convert from LP to natural gas, use the
GROUND ROD
394588 Natural Gas Conversion Kit (ordered separately).
Step-opening gas controls cannot be converted.

WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH.
Follow these warnings exactly:
1. Do not bend the pilot gas tubing at the gas
control or at the pilot burner after the
compression fitting is tightened. Gas leakage at
the connection can result.
2. Always install a sediment trap in the gas supply
line to prevent contamination of the gas control.
3. Do not force the gas control knob. Use only your
hand to turn the gas control knob. If the gas
control knob does not operate by hand, the gas
control should be replaced by a qualified service
technician. Force or attempted repair can result in
a fire or explosion.
These gas controls are shipped with protective seals
over the inlet and outlet tappings. Do not remove the
seals until ready to connect the piping.
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH.
1. Do not attempt to use a gas control set for natural
gas on LP gas or a gas control set for LP gas on
natural gas.
2. When making a conversion, main and pilot burner
orifices must be changed to meet appliance
manufacturer specifications.
Turn off the main gas supply to the appliance.
Remove the regulator cap screw and pressure
regulator adjusting screw. See Fig. 3.
Remove the existing spring.
Insert the replacement spring with the tapered end
down. See Fig. 9.
Install the new plastic pressure regulator adjustment
screw so that the top of the screw is flush (level) with
the top of the regulator. Turn the pressure regulator
adjustment screw clockwise six complete turns. This
provides a preliminary pressure setting of about 10.0 in.
wc (2.5 kPa) for LP regulator and 3.5 in. wc (0.9 kPa)
for natural gas regulator.
Check the regulator setting either with a manometer or
by clocking the gas meter. See the Checkout section.
Install the new cap screw.
Mount the conversion label on the control.
Install the control and appliance according to the
appliance manufacturer instructions.
