APPLICATION
The Honeywell TRADELINE® SmartValveTM System
Controls provide easy field replacement of a wide range
of SV9500, SV9501, SV9502 and SV9602 SmartValve
System models. Gas appliance manufacturers use these
models in many types of gas fired heating appliances
including central furnaces, residential boilers, rooftop
furnaces, commercial cooking appliances, and unit
heaters. These TRADELINE® controls provide
intermittent pilot gas ignition sequencing, pilot flame
sensing, and both pilot and main gas control functions in
a single control. They are directly compatible with the
Q3450 or Q3480 Intermittent Pilot burners used with the
original controls on the appliance.
The TRADELINE® SV9501 and SV9502 SmartValve
models are replacement controls only for the SV9500,
SV9501, and SV9502 models noted in Table 5. Do not
use these controls to replace other types of intermittent
pilot or direct ignition controls. Do not use these controls
to replace SmartValve
Replacement table. The controls might fit, but the gas
flow control functions might not be compatible with the
appliance.
The TRADELINE® SV9602 SmartValve
replacement controls only for the SV9500P, SV9501P,
SV9502P, SV9600P and SV9601P models noted in Table
5. The SV9602 is a prepurge, step-opening model.
IMPORTANT
Do not use these controls to replace
SmartValve
replacement table.
Prepurge is nominally 30 seconds.
The step opening function provides a timed step outlet
pressure at the start of each heating cycle to allow main
burner ignition at reduced outlet pressure.
Reducer bushings are provided with the SV9602 and
SV9601 models for adapting to smaller pipe sizes.

SYSTEM CONTROL
demands on the controls. Special steps are
recommended to prevent nuisance shutdowns and control
failures due to frequent cycling, or severe environmental
conditions such as exposure to moisture, corrosive
chemicals, dust, or excessive heat. Following are the
possible causes of shutdown and the preventative
solutions.
Frequent Cycling
These controls are designed to cycle three to four times
each hour during the heating season. Year around
applications and applications with more frequent cycling
rates can wear out controls more quickly than normal
operation. Perform monthly system checks to make sure
the system operates properly.
Water or Steam Cleaning
Replace any electronic control that gets wet. If the
appliance is likely to be cleaned with water or steam,
cover the control and wiring to protect them from water or
steam flow. Mount the control high enough above the
cabinet bottom to avoid getting it wet during 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. High
humidity around the control can cause the control to
corrode and fail. If the appliance is located in a humid
atmosphere, make sure the air circulation around the
control is adequate to prevent water condensing on the
control. Check the system regularly for signs of
condensation and corrosion.
Corrosive Chemicals
Corrosive chemicals can erode the control, eventually
causing a failure. If chemicals are used for routine
cleaning, make sure they do not touch the control. Where
chemicals are suspended in air, for example, 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 are
problems, cover the control to limit contamination.
Installation
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
Follow these warnings exactly as written.
1. Disconnect the power supply before wiring to
prevent electrical shock and equipment
damage.
2. Turn of the gas supply at the appliance service
valve before starting installation to avoid
dangerous accumulation of fuel gas.
3. Perform gas leak test after completing
installation.
4. Do not bend pilot tubing at ignition system
control or pilot burner after tightening the
compression fitting. Bending can cause gas
leakage at the connection.
5. Always install a sediment trap in the gas supply
line to prevent contamination of the ignition
system.
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
Follow this warning exactly as written.
• Always change the main and pilot burner
orifices when converting between LP and
natural gas. Follow appliance manufacturer
specifications and instructions.
CAUTION
Equipment Damage Hazard.
Improper device replacement will damage the
equipment.
The SV9501, SV9502, SV9602, and SV9601
provide direct replacement only as shown in Table
4 or Table 5 of this manual. Use the Y8610 to
convert standing pilot systems to electronic
ignition systems.
Heat
Excessively high (above 175°F [79°C]) temperatures can
damage the control. Make sure the ambient temperature
at the control does not exceed the control rating. If the
appliance operates at very high temperatures, use
insulation, shielding and proper air circulation as
necessary to protect the control. The appliance
manufacturer should provide proper insulation or
shielding. Make sure there is proper air circulation when
installing the appliance.

SYSTEM CONTROL
Ignition system controls are set at the factory for natural
or LP gas. Do not attempt to use an ignition control made
for LP gas on a natural gas system. Do not attempt to use
an ignition control made for natural gas on an LP gas
system.
Ignition system controls with standard opening regulators
(SV9501M, SV9502M, and SV9601M) or slow opening
regulators (SV9501H and SV9502H) can be converted
between natural gas and LP gas.
Ignition system controls with step opening regulators (P
suffix) cannot be converted between gases.
Selecting the Valve
Make sure when replacing any SmartValveTM that you
know what valve is going in and what valve is coming out.
The SV9501 and SV9502 look slightly different from the
SV9500. The SV9500 features an ON/OFF control knob,
as shown in Fig. 1. The SV9501, SV9502, SV9602, and
SV9601 have an ON/OFF switch, as shown in Fig. 2. The
SV9501, SV9502, SV9601, and SV9602 have a
connector located at the top of the valve instead of on the
front.
The SV9501, SV9502, SV9602, and SV9601 have
identical valve body features and use the same
connectors.
NOTE: The SV9601 and the SV9602 do not have flange
mounting capability.
Use of Pipe Adapters
In some field service applications, space limitations make
it difficult or impossible to thread the gas control onto the
gas supply line. This problem can be resolved for many
installations by using a pipe adapter. Install the pipe
adapter on the end of the supply line in place of the gas
control by following the same precautions and instructions
that are used for installing the gas control. After the pipe
adapter is installed, attach the gas control to the adapter.
NOTE: Using a pipe adapter increases the overall length
of the gas control.
Install Pipe Adapter to Gas Control
Install adapter to gas control as follows:
Bushings
1. Remove seal over gas control inlet or outlet.
2. Apply moderate amount of good quality pipe com-
pound to bushing, leaving two end threads bare.
3. Insert bushing into gas control and carefully thread
pipe into the bushing until tight.
Installing Flange Adapters to Control
(If Required)
Mount any necessary adapters as follows:
Flanges
1. Choose the correct flange for the application.
2. Remove the seal over the ignition system control or
outlet.
3. Make sure the O-ring is fitted in the flange groove. If
the O-ring is not attached or is 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.
5. Insert the screws provided with the flange.
6. Tighten the screws firmly but do not over tighten

nominal range, as shown in Table 2 and 3, 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 the maximum
capacity as shown in Table 3, it might not be possible to deliver the desired outlet pressure. This
is an application issue, not a control failure. Take
whatever steps are necessary to correct the situation.
MAINTENANCE
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
Do not attempt to take the control apart or clean it.
Improper cleaning or reassembly may cause gas
leakage.
Regular preventive maintenance is important in
applications that place a heavy load on system controls.
This include applications in commercial cooking,
agricultural, and industrial industries where these
conditions often exist:
• Heavy cycling. In commercial cooking, the operation,
the equipment operates 100,000 to 200,000 cycles per
year. This can wear out a gas control in one to two
years.
• Exposure to water, dirt, chemicals, and heat can
damage the gas control and shut down the control
system.

• Intermittent use. Appliances that are used seasonally
should be checked before shutdown and before each
use.
• Consequence of unexpected shutdown. Where the
cost of an unexpected shutdown would be high, check
the system frequently.
• Dusty, wet, or corrosive environment. Since these
environments can cause the gas control to deteriorate
more rapidly, check the system frequently.

1. Do not apply a jumper across or short the
control terminals. Doing so may burn out the
heat anticipator in the thermostat or damage
the system transformer.
2. Make sure to check operation after service.
Sequence of Operation
1. Make sure the ignition system control switch is in
the ON position.
2. Follow the sequence of operation shown in Fig. 14.
If the Main Burner Does Not Come On with
Call for Heat
1. Make sure the ignition system control switch is in
the ON position.
2. Adjust the thermostat several degrees above room
temperature.
3. Make sure the appliance is receiving power. See
Fig. 15 or 16, as applicable.
INSTRUCTIONS TO THE
HOMEOWNER
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
Follow these warnings exactly as written.
1. Do not light the pilot flame manually. Pilot flame
lights automatically.
2. Smell around the appliance for gas. Be sure to
smell next to the floor, because LP gas is
heavier than air.
3. If you smell gas:
• Turn off the gas supply at the appliance
service valve. For LP gas systems, turn off
the gas supply at the gas tank.
• Do not light any appliances in the house.
• Do not touch any electrical switches.
• Do not use the phone.
• Leave the building, and go to a neighbor’s
phone to call your gas supplier.
• If you cannot reach your gas supplier, call the
fire department.
4. Do not force or use tools to move the ignition
system control switch. If the switch does not
operate by hand, the ignition system control
must be replaced by a qualified, licensed (if
required) service technician. Force or
attempted repair can result in fire or explosion.
5. Replace the ignition system control if it shows
any evidence of physical damage, tampering,
bent terminals, missing or broken parts,
stripped threads, or exposure to excessive
heat.
IMPORTANT
Follow the warnings in the Instructions to the
Homeowner section.
Follow the operating instructions provided by the
manufacturer of your heating appliance. The
following information assists in a typical ignition
system control application, but the specific
controls used and the procedures outlined by the
manufacturer of your appliance can be different.
Such appliances require special instructions.
Turning the Appliance ON
The pilot flame is lit automatically. If the appliance does
not turn on when the thermostat is set several degrees
above room temperature, follow these instructions:
69-1270—3 10
1. Set the thermostat to its lowest setting to reset the
safety control.
2. Disconnect all electric power to the appliance.
3. Remove the ignition system control access panel.
4. Move the ignition system control switch to OFF.
5. Wait a minimum of five minutes to clear out any
unburned gas. If you smell gas, follow step 3 in the
warning. Otherwise continue to the next step.
6. Move the ignition system control switch to ON.
7. Replace the ignition system control access panel.
8. Reconnect the power to the appliance.
9. Set the thermostat to the desired setting.
10. If the appliance still does not turn on, set the ignition
system control switch to OFF and contact a
qualified, licensed (if required) service technician.

TROUBLESHOOTING
The attached flowcharts provide specific troubleshooting
information for the SV9500, SV9501 and SV9502/
SV9600, SV9601, SV9602 products. These charts assist
the field technician to analyze appliance operation
difficulties.
CAUTION
Equipment Damage.
Can damage connectors on wiring harness.
1. Proper troubleshooting requires measurement
of voltage and resistance with a volt/ohm meter.
2. Use proper size probes and appropriate testing
techniques to assure good test information
without damaging the control terminals,
Use the following basic troubleshooting procedure.

1. Review this information carefully prior to going to
the job site.
2. Identify the specific SmartValve
SV9501, SV9502, SV9600, SV9601, SV9602).
3. Make sure the Q3450/Q3480 HSI element is good.
Disconnect the HSI element from the SmartValveTM.
4.
5. Using a multimeter, measure the HSI element room
temperature resistance. It should be less than 10

SV9601/SV9602 is different from the HSI
element action for SV9500/SV9600. For
SV9500/SV9600, the element is on continuously
during a call for heat until shortly after the pilot
flame is detected, the main valve energizes and
the element turns off. For SV9501/SV9502/
SV9601/SV9602, the call for heat generates a
90-second “trial for pilot ignition.” If no pilot flame
is sensed, it retries after a five minute delay. The
element cycles off and back on once during the
trial for pilot ignition.
