the product to make sure the product is suitable for
your application.
Installer must be a trained, experienced service
3.
technician.
After installation is complete, check out product
4.
operation as provided in these instructions.
WARNING
Oxygen depletion hazard.

asphyxiation.
Use only vented gas valve models on vented
1.
appliances.
Use only unvented gas valve models on
2.
unvented appliances.
WARNING
Fire or explosion hazard.
Can cause property damage, severe injury or
death.
Follow these warnings exactly:
Disconnect power supply before wiring to
1.
prevent electrical shock or equipment damage.
To avoid dangerous accumulation of fuel gas,
2.
turn off gas supply at the appliance service
valve before starting installation, and perform a
Gas Leak Test after the installation is
complete.
Always install the sediment trap in the gas
3.
supply line to prevent contamination of the gas
control.
Do not force the gas control knob. Use only
4.
your hand to turn the gas control knob. Never

CAUTION
Equipment damage.
Can burn out heat anticipator in thermostat.
Never apply a jumper across or short the valve
coil terminals.
IMPORTANT
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.
Follow the appliance manufacturer instructions, if
available; otherwise, use these instructions.
Converting Between Natural and LP Gas
WARNING
Fire or explosion hazard.
Can cause property damage, severe injury or
death.
Do not use a gas control set for natural gas on
1.
an LP gas system or a gas control set for LP
gas on a natural gas system.
When making a conversion, the main pilot
2.
burner orifices must be changed to meet the
appliance manufacturer specifications.
When making a conversion, change main pilot burner
orifices to meet the appliance manufacturer
specifications. Refer to the appliance manufacturer
instructions for orifice specifications and changeover
procedure. Gas controls are factory-set for natural (and
manufactured) or LP gas. Do not attempt to use a control
set for natural (manufactured) gas on LP gas, or a control
set for LP on natural (manufactured) gas.
VS8510A and VS8520A gas controls with a standard
regulator can be converted from one gas to the other with
a conversion kit (ordered separately). Order part no.
395991 to convert from natural (manufactured) to LP
gas. Order part no. 395992 to convert from LP to natural
(manufactured) gas.
VS8510E and VS8520E gas controls with a Convertible
High/Low regulator can be converted from one gas to the
other with a conversion kit (ordered separately). Order
part no. 396087-1 to convert from LP to natural
(manufactured) gas. Order part no. 396087-2 to convert
from natural (manufactured) to LP gas.
High/Low regulator models VS8510D and VS8520D
cannot be converted.
VS8510R and VS8520R
Convertible Pressure Regulators
Gas valves with suffix letter R are convertible pressure
regulator models. They can be converted from natural
gas to LP or from LP to natural gas without a converter
kit.
Before converting the gas valve from one gas to another,
check the gas valve label and the appliance
manufacturer rating plate to make sure the pressure
regulator setting (factory set) meets the appliance
manifold requirements after conversion.
NOTE: Convertible pressure regulator models (suffix
R) do not have field-adjustable regulators. The
natural gas and LP settings are factory-manufactured.
IMPORTANT
Follow these instructions carefully.
CONVERTING THE GAS VALVE
If the factory pressure regulator setting meets the
appliance manifold requirement, convert the gas valve as
follows (see Fig. 1):
Remove the black thread protective cap.
1.
Remove the conversion flip cap by turning it
counterclockwise .
Invert the conversion flip cap so the bottom of the
2.
letters and associated arrow for the gas type
appropriate for the appliance application are face
down toward the valve. NAT is for natural gas and
LP is for liquid petroleum gas.
Tighten the conversion flip cap by turning it clockwise
, using 10 in. lbs of force.
Replace the black thread protective cap.

Location
Locate the combination gas control where it cannot be
affected by steam cleaning, high humidity, dripping water,
corrosive chemicals, dust or grease accumulation or
excessive heat. To assure proper operation, follow these
guidelines:
• Locate gas control in a well-ventilated area.
• Mount gas control high enough to avoid exposure to
flooding or splashing water.
• Assure the ambient temperature does not exceed the
ambient temperature ratings for each component.
• Cover gas control if appliance is cleaned with water,
steam, or chemicals or to avoid dust and grease
accumulation.
• Avoid locating gas control where exposure to
corrosive chemical fumes or dripping water is likely.

Install Piping to Gas 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.
Use new, properly reamed pipe free from chips.
1.
When tubing is used, assure the ends are square,
deburred and clean. All tubing bends must be
smooth and without deformation.
Run pipe or tubing to the control. If tubing is used,
2.
obtain a tube-to-pipe coupling to connect the
tubing to the control.
Install sediment trap in the supply line to the gas
3.
control. See Fig. 1.
Install Control
Mount control 0 to 90 degrees, in any direction,
1.
from the upright position of the gas control knob,
including vertically.
Mount the control so gas flow is in the direction of
2.
the arrow on the side of the control.
Thread pipe 9/16 in. into the control. Do not insert
3.
deeper than 3/8 in. Valve distortion or malfunction
can result if the pipe is inserted too deeply.
Apply a moderate amount of good quality pipe
4.
compound (do not use Teflon tape) to pipe only,
leaving two end threads bare. On LP installations,
use compound resistant to LP gas. See Fig. 2.
Remove seals over control inlet and outlet, if
5.
necessary.
Connect pipe to control inlet and outlet. Use
6.
wrench on either side of the pipe outlet. Refer to
Fig. 3 through 5.
Wiring
Follow the wiring instructions furnished by the appliance
manufacturer, if available, or use the general instructions
provided below. Where these instructions differ from the
appliance manufacturer, follow the appliance
manufacturer instructions. For typical wiring diagrams,
see Fig. 6 and 7.
All wiring must comply with applicable electrical codes
and ordinances.
Disconnect power supply before making wiring
connections to prevent electrical shock or equipment
damage.
Check the power supply rating on the gas control
1.
and make sure it matches the available supply.
Install the transformer, thermostat, and other
controls, as required.
This valve can only be used in a self-generating
2.
system.
Adjust the thermostat heat anticipator to the 0.1A
3.
at 750 mV rating stamped on the valve operator.
OPERATION
The Millivolt Gas Valve System has two different
configurations. The first configuration includes a gas
valve, quick drop-out thermocouple, thermopile, millivolt
thermostat and a pilot burner. In this configuration, the
thermopile drives the operator and the quick dropout
thermocouple operates the power unit. See Fig. 7. The
second configuration includes a gas valve, thermopile,
millivolt thermostat, and a pilot burner. The thermopile
drives the operator and the power unit. See Fig. 8.
