SV9540; SV9640

SmartValve™ System Controls

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 appli-

ances. The specific application of the SmartValve System

is the responsibility of the appliance manufacturer. See

Table 1 for temperature ranges and regulator types.

SPECIFICATIONS

CAUTION

The SV9540; SV9640 provide direct replacement

only. Use the Y8610 to convert standing pilot

systems to electronic ignition systems.

SV9540; SV9640 SmartValve™ SYSTEM CONTROLS

Frequent Cycling

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.

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.

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.

Dust or Grease Accumulation

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.

Heat

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.

appropriate time in the appliance operation, main

gas can flow to the main burner.

NOTE: Controls are shipped with the ignition system

control switch in the ON position. If the appliance

is operated with the ignition system control switch

in the OFF position, the system will respond as if

the air proving switch is stuck in the no airflow

position.

Turn on Main Burner

Follow the instructions provided by the appliance manufac-

turer or turn up the thermostat to call for heat.

Perform Gas Leak Test

WARNING

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.

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:

Fig. 11. Proper flame adjustment.

Check and Adjust Gas Input and

Burner Ignition

CAUTION

1. 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.

2. 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.

3. IF CHECKING GAS INPUT WITH MANOM-

ETER: 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 discon-

necting manometer and replacing plug.

Repeat Gas Leak Test at plug with main

burner operating.

NOTE: Check the inlet pressure before adjusting the

pressure regulator.

MAINTENANCE

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.

Regular preventive maintenance is important in applica-

tions 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.

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

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.

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.

The maintenance program should include regular check-

out of the control as outlined in the Startup and Checkout

section, and the control system as described in the

appliance manufacturer literature.

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.

69-105911

SV9540; SV9640 SmartValve™ SYSTEM CONTROLS

The system should be replaced if:

• It does not perform properly on checkout or trouble-

shooting.

• 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.
