INSTALLATION
Automatic Ignition Control domestic and commercial
boiler systems are used on a wide variety of equipment.
Some of these applications may make heavy demands on
the controls, either because of frequent cycling, or
because of moisture, corrosive chemicals, dust or
excessive heat in the environment. In these situations,
special steps may be required to prevent nuisance
shutdowns and premature control failures. These
applications require Honeywell Engineering review;
contact your Honeywell Sales Representative for
assistance.
Frequent Cycling
These controls are designed for use on domestic and
commercial boiler systems that typically cycle less than
10,000 cycles per year. In an application with significantly
greater cycling rates, we recommend monthly checkout
because the controls may wear out more quickly.
Water or Steam Cleaning
Once a module or gas control has been wet, it may
operate unreliably and must be replaced. If the appliance
is likely to be cleaned with water or steam, the controls
and associated wiring should be covered so that water or
steam cannot reach them. The controls should be high
enough above the bottom of the cabinet so they will not be
subjected to flooding or splashing during normal cleaning
procedures. If necessary, shield the controls to protect
them from splashing water. A NEMA 4 enclosure is
recommended.
High Humidity or Dripping Water
Over time, dripping water or high ambient humidity can
create unwanted electrical paths on the module circuit
board, causing the module to fail. Never install an
appliance where water can drip on the controls.
In addition, high ambient humidity can cause the control
to corrode and finally fail.
Where the appliance may be installed in a humid
atmosphere, make sure air circulation around the module
and gas control is adequate to prevent condensation. It is
also important to regularly check out the system. A NEMA
4 enclosure may be needed.
Corrosive Chemicals
Corrosive chemicals can also attack the module and gas
control and eventually cause a failure. Where chemicals
may be used routinely for cleaning, make sure the
cleaning solution cannot reach the controls. Where
chemicals are likely to be suspended in the air, as in some
industrial and agricultural applications, protect the module
from exposure with a NEMA 4 enclosure.
Dust or Grease Accumulation
Heavy accumulation of dust or grease may cause the
controls to malfunction. Where dust or grease may be a
problem, provide covers for the module and gas control
that limit environmental contamination. A NEMA 4
enclosure is recommended for the module.
Heat
The controls can be damaged by excessively high
temperatures. Make sure the maximum ambient
temperature at the control locations will not exceed the
rating of the control. If the appliance normally operates at
very high temperatures, insulation, shielding, and air
circulation may be necessary to protect the controls.
Proper insulation or shielding should b provided by the
appliance manufacturer; make sure adequate air
circulation is maintained when the appliance is installed.

INSTALLATION AND
CHECKOUT
When Installing This Product…
1. Read these instructions carefully. Failure to follow
them could damage the product or cause a
hazardous condition.
2. Check the ratings given in the instructions and on
the product to make sure they are suitable for your
application.
3. Installer must be a trained, experienced service
technician.
4. After installation is complete, check out product
operation as provided in these instructions.
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
1. The module can malfunction if it gets wet,
leading to accumulation of explosive gas.
• Never install where water can flood, drip or
condense on module.
• Never try to use a module that has been
wet—replace it.
2. Liquefied petroleum (LP) gas is heavier than air
and will not vent upward naturally.
• Do not light pilot or operate electric switches,
lights, or appliances until you are sure the
appliance area is free of gas.
3. If a new gas control is to be installed, turn off
gas supply before starting installation. Conduct
Gas Leak Test according to gas control
manufacturer instructions after the gas control
is installed.
4. If module must be mounted near moisture or
water, provide suitable waterproof enclosure.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect power supply before beginning wiring
to prevent electrical shock or equipment damage.
Perform Preinstallation Safety
Inspection
The preinstallation checks described in ANSI Standard
Z21.71 must be done before a replacement module is
installed. If a condition which could result in unsafe
operation is detected, the appliance should be shut off
and the owner advised of the unsafe condition. Any
potentially unsafe condition must be corrected before
proceeding with the installation.
Maintenance Requirements in Severe
Environments
Regular preventive maintenance is important in any
application, but especially so in commercial, agricultural,
and industrial applications, because:
1. In such applications, particularly commercial, the
equipment can operate 100,000 to 200,000 cycles
per year. Such heavy cycling can wear out the gas
control in one to two years. A normal boiler applica-
tion, for which the controls were intended, typically
operate fewer than 10,000 cycles per year.
2. Exposure to water, dirt, chemicals, and heat can
damage the module or the gas control and shut
down the control system. A NEMA 4 enclosure can
reduce exposure to environmental contaminants.
The maintenance program should include regular
checkout of the system as outlined under Checkout.
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
Do not attempt to take the module apart or to
clean it. Improper reassembly and cleaning may
cause unreliable operation, leading to an
accumulation of explosive gas.
Maintenance frequency must be determined individually
for each application. Some considerations are:
Cycling frequency. Appliances that may cycle more than
10,000 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 controls to deteriorate more
rapidly, the system should be checked more often.
Any control should be replaced if it does not perform
properly on checkout or troubleshooting. In addition,
replace any module if it is wet or looks like it ever has
been wet. Protective enclosures as outlined under
Planning the Installation are recommended regardless of
checkout frequency.
Mount Module
Select a location close enough to the burner to allow a
short (3 ft. [0.9 m] maximum), direct cable route to the
igniter. Ambient temperature at the module must be within
the range listed under Specifications. The module must
be protected from water, moisture, corrosive chemicals
and excessive dust and grease. Refer to Fig. 2 and 3 for
recommended slot/hole pattern in appliance.

WIRING
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect the power supply before making wiring
connections to prevent electrical shock or
equipment damage.
Check the wiring diagram furnished by the appliance
manufacturer for circuits differing from the wiring hookup
shown in Fig. 4. Carefully follow any special instructions
affecting the general procedures outlined below.
IMPORTANT
1. All wiring must comply with applicable local
electrical codes and ordinances.
2. When installing a hot surface igniter, the
leadwires should be kept as short as possible
and should not be allowed to rest against
grounded metal surfaces.
3. A common ground is required for the S93XX and
the main burner. The 24V “secondary” plug inter-
nally grounds one side of the transformer. Any
auxiliary controls or limits must not be in the
grounded leg. In addition, the appliance should
be earth-grounded.
4. Make sure the transformer has adequate VA.
The ignition module requires at least 0.2A at 24
Vac. Add the current draws of all other devices in
the control circuit, including the gas control, and
multiply by 24 to determine the total VA
requirements of these components. Add this
total to 5.0 VA (for the module). The result is the
minimum transformer VA rating. Use a Class II
transformer if replacement is required.
5. Check that L1 (hot) and L2 (neutral) are wired to
the proper terminals.
Connect Ignition Cable (S936XAXXXX,
S938XAXXXX)
Use Honeywell ignition cable or construct an ignition
cable that conforms to suitable national standards, such
as Underwriters Laboratories Inc. See Specifications
section. To construct a cable, fit one end (the module end)
with 1/4 in. connector receptacle and the other with a
connector to match the pilot assembly. Protect both ends
with insulated boots.
NOTE: Cable length must be 36 in. (0.9 m) or less.
The cable must not be in continuous contact
with a metal surface or spark voltage will be
greatly reduced. Use ceramic or plastic
standoff insulators as required.
1. Connect one end of the cable to the male
quick-connect SPARK terminal on the module.
2. Connect the other end of the cable to the igniter or
igniter-sensor stud on the pilot burner/igniter-
sensor.
S938X Direct Spark Ignition (DSI)
Versions
See Fig. 5 for direct spark ignition wiring details.
Connect Inducer (Inducer Models)
An inducer can be used with modules provided with an
inducer plug connector. The Molex®plug provided
simplifies wiring connections.
To connect the inducer, follow the wiring diagrams
supplied with the inducer for typical connections.
Connect Remaining Module Connectors
Connect remaining system components to the ignition
module terminals as shown in the appropriate wiring
diagrams, Fig. 4.
Connect Gas Control
Use No. 18 AWG solid or stranded wire. Connect to gas
control terminals as shown in wiring diagrams, using
terminals appropriate to the gas control.
Ground Control System
The igniter, flame sensor and module must share a
common ground with the main burner. Use AWM
insulated wire with a minimum rating of 105°C (221°F) for
the ground wire; asbestos insulation is not acceptable. If
necessary, use a shield to protect the wire from radiant
heat generated by the burner.
The burner serves as the common grounding area. If
there is not a good metal-to-metal contact between the
burner and ground, run a lead from the burner to ground.
NOTE: “Earth” ground is not required.
Transformer: Add current ratings of module, gas control,
vent damper and any other components of the control
system to determine transformer size requirements.

Temperature Control
Temperature control setpoint on the module can be
adjusted as described in the following sections. Some
modules with temperature control also include a three-
digit display on the printed circuit board to facilitate
adjustments and troubleshooting.
For modules that do not include temperature control on
the module refer to the Honeywell Installation Instructions
for the specific interface module or the appliance
manufacturer’s instructions. A separate automatic gas
shutoff device is not required in a system that uses this
control to meet requirements for CSA International ANSI
Z21.87 and UL 353.
The overall range of the setpoint is model-dependent but
is within 130°F to 240°F (54°C to 116°C). Select devices
may have different ranges.
Adjusting Settings for Models with
“On-Board” Display
To discourage unauthorized changing of settings, a
procedure to enter the adjustment mode is required. To
enter the adjustment mode, press the UP, DOWN, and I
buttons (see Fig. 1) simultaneously for three seconds.
Press and release the Ibutton until the parameter
requiring adjustment is displayed.
Then press the UP or DOWN button until the parameter
has reached the desired value. After 60 seconds without
any button inputs, the control will automatically return to
the READ mode.
Display
In the RUN mode, status items and parameters are
viewable.
To read settings, press and release the I key to find the
parameter of interest. For example, press and release I
until setpoint (sp) is displayed, followed by a three-digit
number, i.e., 220, followed by °F or °C. See Display

See Table 6 for the IBC display screens.
Boiler Temperature Controller
When the water temperature reaches setpoint, the
controller ends the heating cycle. When the water
temperature drops below the setpoint minus the
differential, the control restarts a heat cycle to re-heat the
tank of water.
If the water temperature exceeds the max allowed
temperature, the control enters a manual reset lockout
state. For models that have reset capability, press any on-
board button (when present), cycle power, or use the local
(“rSt”) to reset.
CHECKOUT
Put the system into operation and observe operation
through at least one complete cycle to make sure that the
controller operates properly. See Troubleshooting section
to assist in determining system operation.
LOCATION AND MOUNTING
Sensing Bulb(s)
The boiler manufacturer usually provides a tapping for the
sensing bulb at a point where average water temperature
can be measured. See Fig. 8. Follow the boiler
manufacturer instructions.
The sensing bulb can be installed in an immersion well.
Wells and fittings must be ordered separately. See 68-
0040.
When an immersion well is used, the sensor should fit
snugly and should touch the bottom of the well for best
temperature response. Use heat-conductive compound
(Honeywell part no. 107408) to fill the space between the
bulb and the well to improve heat transfer characteristics
(optional). Make sure the sensor is held firmly in the well.
WIRING
IMPORTANT:
For maximum trouble free operation, run the
sensor leadwires separately from any other cur-
rent-carrying wires.

Mounting Sensor and Thermowell
The remote upper temperature sensor is installed in an
immersion well (Fig. 9) that extends into the supply water
side of the boiler.
Immersion Well Fitting
The immersion well must snugly fit the sensing bulb for
good thermal response. Install as follows:
1. Use tapping provided by tank manufacturer, if possi-
ble, or select an area where typical water tempera-
ture is best measured.
2. If tank is filled, drain to below point where bulb will
be installed.
3. Screw well into tank.
4. Insert bulb into well, pushing wires until bulb bot-
toms in well.
5. Attach mounting clamp end of well spud.
6. With mounting clamp attached to well spud (make
sure jaws of clamp hook over ridge at end of spud,
as shown at points A in Fig. 9), adjust sensing lead-
wire to fit through mounting clamp groove, as shown
at point B in Fig. 9.
7. Tighten draw nut until mounting clamp is firmly
attached to well spud and wires are held securely in
place.
CAUTION
Do not secure draw nut so tightly that
mounting clamp collapses tubing.
Fig. 9. Immersion well fitting for sensor.
Wiring
Disconnect power supply before installation to prevent
electrical shock or equipment damage. All wiring must
comply with local codes and ordinances regarding wire
size, type of insulation, enclosure, etc.
OPERATION AND CHECKOUT
Operation
The S9360A, S9361A, S9380A and S9381A continuously
monitor the temperature of the boiler water and enable or
disable the burner based on this temperature data. In
general, when a “Call for Heat” occurs, the ignition portion
of the control module proceeds through the steps
necessary to start the burner and heats the water in the
boiler until the setpoint temperature is achieved. At this
point the burner is de-activated, the ignition module
completes the heating cycle, returns to idle and waits for
the temperature to drop again. The circulator is turned on
throughout the “Call for Heat.”
See Fig. 10 for a graphical representation of a simple
control cycle. Note that the setpoint differential may vary
based on OS number.
High Limit Controller
All models include a 3-wire temperature sensor interface,
“Sensor 1,” which is utilized for High Limit functionality in
addition to the thermostatic control of the water heater
burner. If the temperature sensor ever indicates a
temperature above the maximum limit then the control
enters over temperature mode. In over temperature mode
no heating will occur.
Fig. 10. Basic control algorithm example.
Thermal Purge Operation
The intent of thermal purge is to insure usable residual
heat in the boiler is circulated until it is sufficiently
depleted from the system before the burner is allowed to
fire. To that end, on a call for heat, the burner is held off
while the circulator runs until the boiler temperature drops
to the thermal purge temperature limit or a time delay is
exceeded. Both of these parameters are adjustable.
When the boiler temperature falls below the thermal purge
temperature limit or the time delay expires, the burner is
allowed to fire.
In addition to the thermal purge temperature and thermal
purge time delay parameters, two other conditions release
the integrated boiler controller from thermal purge and
allow the burner to run in order to maintain comfort in the
space:
• The boiler temperature has dropped 10 °F from the
boiler water temperature measured at the beginning of
the beginning of the call for heat.
• Boiler temperature is cooling at a rate greater than
5 °F/minute while the circulator is running.

TROUBLESHOOTING
IMPORTANT
1. The following service procedures are provided
as a general guide. Follow appliance manufac-
turer’s service instructions if available.
2. On lockout and retry models, meter readings
between gas control and ignition module must
be taken within the trial for ignition period. Once
the ignition module shuts off, lockout models
must be reset through the key buttons and dis-
play. On retry models, wait for retry or reset at
the thermostat.
3. If any component does not function properly,
make sure it is correctly installed and wired
before replacing it.
4. The ignition module cannot be repaired. If it mal-
functions, it must be replaced.
5. Only trained, experienced service technicians
should service ignition systems.
Perform the checkout as the first step in troubleshooting.
Then check the appropriate troubleshooting guide and the
schematic diagram to pinpoint the cause of the problem. If
troubleshooting indicates an ignition problem, see Ignition
System Checks below to isolate and correct the problem.
Following troubleshooting, perform the checkout
procedure again to be sure system is operating normally.
Intermittent Pilot
Ignition System Checks
STEP 1: Check ignition cable.
Make sure:
• Ignition cable does not run in contact with any metal
surfaces.
• Ignition cable is no more than 36 in. [0.9 m] long.
• Connections to the ignition module and to the igniter or
igniter-sensor are clean and tight.
• Ignition cable provides good electrical continuity.
STEP 2: Check ignition system grounding. Nuisance
shutdowns are often caused by a poor or erratic ground.
• A common ground, usually supplied by the pilot burner
bracket, is required for the module and the pilot burner/
igniter sensor.
— Check for good metal-to-metal contact between
the pilot burner bracket and the main burner.
— Check the ground lead from the GND(BURNER)
terminal on the module to the pilot burner. Make
sure connections are clean and tight. If the wire is
damaged or deteriorated, replace it with No. 14-18
gauge, moisture-resistant, thermoplastic insu-
lated wire with 105° C [221° F] minimum rating.
—Check the ceramic flame rod insulator for cracks
or evidence of exposure to extreme heat,
which can permit leakage to ground. Replace
pilot burner/igniter-sensor and provide shield
if necessary.
—If flame rod or bracket are bent out of position,
restore to correct position.
STEP 3: Check spark ignition circuit.
• Disconnect the ignition cable at the SPARK terminal on
the module.
WARNING
The ignition circuit generates over 10,000 volts
and electrical shock can result.
Energize the module and listen for the audible sparking
noise. When operating normally, there should be a
buzzing noise that turns on and off twice per second for a
duration of 1–7 seconds, depending on the model.
STEP 4: Check pilot and main burner lightoff.
• Set the system to call for heat by turning the
thermostat above room temperature.
• Watch the pilot burner during the ignition sequence.
See if:
— Ignition spark continues after the pilot is lit.
— The pilot lights and the spark stops, but main
burner does not light.
• If so, ensure adequate flame current as follows.
— Turn off furnace at circuit breaker or fuse box.
— Clean the flame rod with emery cloth.
— Make sure electrical connections are clean and
tight. Replace damaged wire with moisture-resis-
tant No. 18 wire rated for continuous duty up to
105° C [221° F].
— Check for cracked ceramic insulator, which can
cause short to ground, and replace igniter-sensor
if necessary.
— At the gas valve, disconnect main valve wire from
the MV terminal.
— Turn on power and set thermostat to call for heat.
The pilot should light but the main burner will
remain off because the main valve actuator is dis-
connected.
— Check the pilot flame. Make sure it is blue, steady
and envelops 3/8 to 1/2 in. [10 to 13 mm] of the
flame rod. See Fig. 12 for possible flame problems
and their causes.
— If necessary, adjust pilot flame by turning the pilot
adjustment screw on the gas control clockwise to
decrease or counterclockwise to increase pilot
flame. Following adjustment, always replace pilot
adjustment cover screw and tighten firmly to
assure proper gas control operation.
— Set temperature below room setpoint to end call
for heat.
• Recheck ignition sequence as follows.
— Reconnect main valve wire.
— Adjust thermostat above room temperature.
— Watch ignition sequence at burner.
— If spark still doesn’t stop after pilot lights, replace
module.
— If main burner doesn’t light or if main burner lights
but system locks out, check module, ground wire
and gas control as described in appropriate trou-
bleshooting chart.
Troubleshooting Error Codes
The integrated boiler control uses advanced diagnostic
capability to assist in troubleshooting error conditions.
Table 8 shows the codes that could arise on the remote or
integrated display during a fault. Suggestions are
provided in Table 5 for servicing these potential errors.
