SV9540; SV9640
SmartValve™ System Controls
INSTALLATION INSTRUCTIONS

APPLICATION
The SV9540; SV9640 SmartValve™ System Controls
combine gas flow control and electronic intermittent pilot
sequencing functions into a single unit. The low voltage
igniter, flame sensor and pilot burner are supplied by the
Q3450 or Q3480 Pilot Hardware. Provides all gas ignition
safety functions by controlling gas flow, ignition source,
and a 120 Vac or 240 Vac combustion air blower. The
control also monitors the appliance airflow proving switch
and limit string to assure proper appliance operation.
Provides prepurge, postpurge, timed trial for pilot igniton,
with 100 percent shutoff and continuous retry. Diagnostic
LED indicates system status.
This control communicates directly with the ST9160
Electronic Fan Timer (EFT) in typical forced warm air
furnace applications. It also interfaces with the 208907
Terminal Board, providing compatibility with power stealing
thermostats. Or, it directly interfaces with the appropriate
power supplies and a system thermostat for additional
appliance applications. When controlled directly by a
thermostat, the control does not provide a postpurge
function, as power to the control is removed when the
thermostat call for heat ends.
The SV9540; SV9640 system is suitable for a wide range
of fan assisted combustion gas-fired appliances including
furnaces, rooftop furnaces, boilers, unit heaters, infrared
heaters, water heaters and commercial cooking appliances. The specific application of the SmartValve System
is the responsibility of the appliance manufacturer. See
Table 1 for temperature ranges and regulator types.

When intermittent pilot systems are used on central
heating equipment in barns, greenhouses, and commercial
properties and on heating appliances such as commercial
cookers, agricultural equipment, industrial heating
equipment and pool heaters, heavy demands are made on
the controls. Special steps may be required to prevent
nuisance shutdowns and control failure due to frequent
cycling, severe environmental conditions related to
moisture, corrosive chemicals, dust or excessive heat.
These applications require Honeywell Home and Building
Control Engineering review; contact your Honeywell Sales
Representative for assistance.

Flange kits include one flange, one O-ring and four
mounting screws.
Do not use flanges on control models with 3/4 in. inlet
and 3/4 in. outlet. On models with 1/2 in. inlet and
3/4 in. outlet, use flanges only on the 1/2 in. inlet side.

69-1059

Review the following conditions that can apply to your
specific installation and take the precautionary steps
suggested.

SV9540; SV9640 SmartValve™ SYSTEM CONTROLS

Frequent Cycling

WARNING

This control is designed for use on appliances that typically
cycle three to four times an hour only during the heating
season. In year-around applications with greater cycling
rates, the control can wear out more quickly. Perform a
monthly checkout.

FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH
Follow these warnings exactly:
1. Disconnect power supply before wiring to
prevent electrical shock or equipment
damage.
2. To avoid dangerous accumulation of fuel gas,
turn off gas supply at the appliance service
valve before starting installation, and perform
Gas Leak Test after completion of installation.
3. Do not bend pilot tubing at ignition system
control or pilot burner after compression fitting
is tightened, or gas leakage at the connection
can result.
4. Always install a sediment trap in gas supply
line to prevent contamination of ignition
system control.

Water or Steam Cleaning
If a control gets wet, replace it. If the appliance is likely to
be cleaned with water or steam, protect (cover) the control
and wiring from water or steam flow. Mount the control
high enough above the bottom of the cabinet so it does not
get wet during normal cleaning procedures.

High Humidity or Dripping Water
Dripping water can cause the control to fail. Never install
an appliance where water can drip on the control.
In addition, high ambient humidity can cause the control to
corrode and fail. If the appliance is in a humid atmosphere,
make sure air circulation around the control is adequate to
prevent condensation. Also, regularly check out the
system.

WARNING

LINE VOLTAGE
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH.
Never apply a jumper across or short any of the
terminals in the SV9540; SV9640 wiring harness.
This can damage the system transformer or the
control.

Corrosive Chemicals
Corrosive chemicals can attack the control, eventually
causing a failure. If chemicals are used for routine
cleaning, avoid contact with the control. Where chemicals
are suspended in air, as in some industrial or agricultural
applications, protect the control with an enclosure.

Follow the appliance manufacturer instructions if available;
otherwise, use these instructions as a guide.

Dust or Grease Accumulation

Converting Ignition System Control
from Natural Gas to LP Gas Application
(or LP Gas to Natural Gas Application)

Heavy accumulations of dust or grease can cause the
control to malfunction. Where dust or grease can be
a problem, provide covers for the control to limit
contamination.

WARNING

Heat

FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH
Do NOT attempt to convert step-opening models
(SV9540P/SV9542P; SV9640P/SV9642P). Always
change the main and pilot burner orifices when
converting from natural to LP gas or from LP to
natural gas. Follow appliance manufacturer
specifications and instructions carefully to assure
proper appliance conversion.

Excessively high temperatures can damage the control.
Make sure the maximum ambient temperature at the
control does not exceed the rating of the control. If the
appliance operates at very high temperatures, use
insulation, shielding, and air circulation, as necessary, to
protect the control. Proper insulation or shielding should be
provided by the appliance manufacturer; verify proper air
circulation is maintained when the appliance is installed.

INSTALLATION

Ignition system controls are factory-set for natural (and
manufactured) or LP gas. Do not attempt to use an ignition
system control set for natural (manufactured) gas on LP
gas, or an ignition system control set for LP gas on natural
(manufactured) gas.

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.

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

1. Cut tubing to the desired length and bend as
necessary for routing to the pilot burner. Do not
make sharp bends or deform the tubing. Do not
bend the tubing at the ignition system control after
the compression nut is tightened, because this can
result in gas leakage at the connection.
2. Square off and remove burrs from the end of
the tubing.
3. Unscrew the brass compression fitting from the pilot
outlet (Fig. 4). Slip the fitting over the tubing and
slide out of the way. See Fig. 6
4. Push the tubing into the pilot gas tapping on the
outlet end of the control until it bottoms. While
holding the tubing all the way in, slide the fitting into
place and engage the threads—turn until finger tight.
Then tighten one more turn with a wrench. Do not
overtighten.

FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH
Check for gas leaks with soap and water solution
any time work is done on a gas system.

Fig. 11. Proper flame adjustment.

Check and Adjust Gas Input and
Burner Ignition

CAUTION

Do not spray soap and water solution on the
SmartValve housing. Do not use an excessive
amount of soap and water solution to perform the
gas leak test. These can damage the control.

Gas Leak Test
1. Paint pipe connections upstream of the ignition
system control with rich soap and water solution.
Bubbles indicate a gas leak.
2. If a leak is detected, tighten the pipe connections.
3. Stand clear of the main burner while lighting to
prevent injury caused from hidden leaks that could
cause flashback in the appliance vestibule. Light the
main burner.
4. With the main burner in operation, paint the pipe
joints (including adapters) and the control inlet and
outlet with rich soap and water solution.
5. If another leak is detected, tighten the adapter
screws, joints, and pipe connections.
6. Replace the part if a leak cannot be stopped.

Check and Adjust Pilot Flame
The pilot flame should envelop 3/8 to 1/2 in. (10 to 13 mm)
of the tip of the flame rod. It should also be in continual
contact with the ground electrode. See Fig. 11. If the pilot
flame is small or lazy, or does not touch the ground
electrode, the inlet gas pressure may be too low, or the
pilot orifice may be partially clogged. Check and repair as
necessary. If the pilot flame is hard and noisy, the inlet gas
pressure may be too high. The ignition system control has
a pilot adjustment mechanism to reduce the pilot flow if
necessary. The pilot adjustment is shipped at the full pilot
gas flow rate. If pilot adjustment is necessary, proceed as
follows:

Do not exceed input rating stamped on
appliance nameplate, or manufacturer’s
recommended burner orifice pressure for size
orifice(s) used. Make certain primary air
supply to main burner is properly adjusted for
complete combustion. Follow instructions of
appliance manufacturer.
IF CHECKING GAS INPUT BY CLOCKING
GAS METER: Make certain there is no gas
flow through the meter other than to the
appliance being checked. Other appliances
must remain off with the pilots extinguished (or
that consumption must be deducted from the
meter reading). Convert flow rate to Btuh as
described in form 70-2602, Gas Controls
Handbook, and compare to Btuh input rating
on appliance nameplate.
IF CHECKING GAS INPUT WITH MANOMETER: Make sure the ignition system control
is in the OFF position before removing outlet
pressure tap plug to connect manometer
(pressure gauge). Also move the ignition
system control switch to the OFF position
when removing the gauge and replacing the
plug. Before removing inlet pressure tap plug,
shut off gas supply at the manual valve in the
gas piping to the appliance or, for LP, at the
tank. Also shut off gas supply before disconnecting manometer and replacing plug.
Repeat Gas Leak Test at plug with main
burner operating.

NOTE: Check the inlet pressure before adjusting the
pressure regulator.

SV9540; SV9640 SmartValve™ SYSTEM CONTROLS

using a manometer at the ignition system control
inlet pressure tap. If the inlet pressure is in the
nominal range (see Tables 7A and 7B), replace the
ignition system control. Otherwise, take the
necessary steps to provide proper gas pressure to
the control.

1. Carefully check the main burner lightoff. Make sure
that the main burner lights smoothly and that all
ports remain lit.
2. Check the full rate manifold pressure listed on the
appliance nameplate. Ignition system control full rate
outlet pressure should match this rating.
3. With main burner operating, check the ignition
system control flow rate using the meter clocking
method or check pressure using a manometer
connected to the outlet pressure tap on the ignition
system control. See Fig. 4.
4. If necessary, adjust the pressure regulator to
match the appliance rating. See Tables 7A and 7B
for factory-set nominal outlet pressure and
adjustment range.
a. Remove the pressure regulator adjustment
cap screw.
b. Using a screwdriver, turn the inner adjustment
screw clockwise
to increase or
counterclockwise
to decrease the gas
pressure to the burner.
c. Always replace the cap screw and tighten
firmly to prevent gas leakage.
5. If the desired outlet pressure or flow rate cannot be
achieved by adjusting the ignition system control,
check the ignition system control inlet pressure

NOTE: If the burner firing rate is above 150,000
Btuh on SV9540 models (see Table 3 for
SV9640 capacities), it may not be possible
to deliver the desired outlet pressure. This
is an application issue, not a control failure.
Take whatever steps are required to
correct the situation.
6. STEP-OPENING PRESSURE REGULATORS
ONLY. Carefully check the burner lightoff at step
pressure. Make sure the burner lights smoothly
and without flashback to the orifice. Make sure all
ports remain lit. Cycle the burner several times,
allowing at least 60 seconds between cycles for
the regulator to resume the step function. Repeat
after allowing the burner to cool. Readjust the full
rate outlet pressure, if necessary, to improve
lightoff characteristics.

• Exposure to water, dirt, chemicals and heat can damage
the gas control and shut down the control system.

MAINTENANCE

The maintenance program should include regular checkout of the control as outlined in the Startup and Checkout
section, and the control system as described in the
appliance manufacturer literature.

WARNING

FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY, OR DEATH
Do not attempt to take the control apart or clean
it. Improper cleaning or reassembly can cause
gas leakage.

Maintenance frequency must be determined individually
for each application. Some considerations are:
• Cycling frequency. Appliances that may cycle 20,000
times annually should be checked monthly.
• Intermittent use. Appliances that are used seasonally
should be checked before shutdown and again before
the next use.
• Consequence of unexpected shutdown. Where the cost
of an unexpected shutdown would be high, the system
should be checked more often.
• Dusty, wet, or corrosive environment. Since these
environments can cause the gas control to deteriorate
more rapidly, the system should be checked more often.

Regular preventive maintenance is important in applications such as in the commercial cooking and agricultural
and industrial industries that place a heavy load on system
controls because:
• In many such applications, particularly commercial
cooking, the equipment operates 100,000 to 200,000
cycles per year. Such heavy cycling can wear out the
gas control in one to two years.

Setting Range

Step

SV9540; SV9640 SmartValve™ SYSTEM CONTROLS

The system should be replaced if:
• It does not perform properly on checkout or troubleshooting.
• The gas control is likely to have operated for more than
200,000 cycles.
• The control is wet or looks as if it has been wet.

CAUTION
1.

Do not apply a jumper across or short any of
the terminals in the SV9540; SV9640 wiring
harness. Doing so can damage the system
transformer or the system control.
After servicing, verify proper system operation.

SERVICE

IMPORTANT
Allow 60 seconds after shutdown before reenergizing step-opening model to assure lightoff
at step pressure.

WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
