PLANNING THE
INSTALLATION
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
1. Planthe installation asoutlinedbelow.
2. Plan for frequent maintenance as described in
theMaintenancesection.
Intermittent pilot systems are used on a wide variety of
central heating equipment and on heating appliances
such as commercial cookers, agricultural equipment,
industrial heating equipment and pool heaters. Some of
these applications may make heavy demands on the
controls,eitherbecauseoffrequentcycling,orbecauseof
moisture, corrosive chemicals, dust or excessive heat in
theenvironment.Inthesesituations,specialsteps maybe
required to prevent nuisance shutdowns and premature
control failure. These applications require special
Honeywell review; contact your Honeywell Sales
Representativeforassistance.
Review the following conditions that can apply to your
specific installation and take the precautionary steps
suggested.
Frequent Cycling
These controls are designed for use on appliances that
typically cycle three to four times an hour only during the
heating season. In year-round applications with greater
cycling rates, the control can wear out more quickly;
perform a monthly checkout.
Water or Steam Cleaning
If the control gets wet, replace it. If the appliance is likely
to be cleaned with water or steam, protect (cover) the
controls and wiring from water or steam flow. Mount the
controls high enough above the bottom of the cabinet so
they do not get wet during normal cleaning procedures.
Use a NEMA 4 enclosure for the ignition control.

High Humidity or Dripping Water
Dripping water can cause the control to fail. Never install an
appliance where water can drip on the controls.
Inaddition,highambienthumiditycandamagethecontrol.
If the appliance is in a humid atmosphere, make sure air circulation
around the controls is adequate to prevent condensation. Also,
regularly check out the system. A NEMA 4 enclosure is recommended
for the ignition module.
Corrosive Chemicals
Corrosive chemicals can attack the module and gas control,
eventuallycausingafailure.Ifchemicalsareused for routine
cleaning, make sure they do not reach the controls. Where
chemicals are suspended in air,as in someindustrialoragricultural
applications,useaNEMA4 enclosurefortheignitionmodule.
Dust or Grease Accumulation
Heavy accumulations of dust or grease can cause controls to
malfunction. Where dust or grease can be a problem, provide
covers for the module and the gas control to limit contamination. A
NEMA 4 enclosure is recommended for the ignition module.
Heat
Excessively high temperatures can damage controls. 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 controls. Proper insulation or shielding
should be provided by the appliance manufacturer; verify proper air
circulation is maintained when the appliance is installed.
INSTALLATION
When Installing This Product…
1. Read these instructions carefully. Failure to follow them
could damage the product orcause ahazard- ouscondition.
2. Check the ratingsgiven intheseinstructionsto make

WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property damage.
Disconnect power supply before beginning wiring or
making wiring connections to prevent electrical shock or
equipmentdamage.
CAUTION
1. If a new gas control is to be installed, turn off the gas
supply before starting installation. ConductaGas

CAUTION
Equipment Damage Hazard.
Water can cause equipment damage or malfunction.
If the module must be mounted near water or moisture,
provide suitable waterproof enclosure.
Maintenance Requirements in Severe
Environments
Regular preventive maintenance is important in any application.
WARNING
Fire or Explosion Hazard.
May 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.
Maintenance frequency must be determined individually for each
application. Some considerations are:
• Cycling frequency. Appliances that may cycle more than 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 modules to deteriorate more rapidly,the system
should be checked more often.
Any module 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 has ever been wet. Protective enclosures as
outlined under “Planning the Installation” are recommended
regardless of checkout frequency.
Location
The mounting location must provide:
— Good,clearaccessto the field wiring terminals.

Mount the Ignition Module
Select a location close enough to the burner to allow a short (3 ft.
[0.9 m] max.), direct cable route to the pilot burner. Ambient
temperature at the module must be within the range listed under
Operating Temperature, on page 2. The module must be protected
from water, moisture, corrosive chemicals and excessive dust and
grease.
Mount the module with the terminals down to protect them from
dripping water and dust. As an alternative, it can also be mounted
with theterminals on either side.
IMPORTANT
Do not mount with terminals facing up.
M29897
Fig. 1. Incorrect Mounting (Model S8600M shown).
Fasten securely with four No. 6-32 machine or No. 8 sheet metal
screws.
Mount the System Controls
Mount any required controls, such as the gas control, spark
igniter, flame sensor, thermostat, limit, and transformer according
to manufacturer’s instructions.
Wire the System
CAUTION
Equipment Damage Hazard.
Disconnect power supply before beginning wiring or
making wiring connections to prevent electrical shock or
equipmentdamage.
All wiring must comply with local codes and ordinances. See Fig. 2
and Table 4 for proper wiring connections.
IMPORTANT
1. As shown in thewiringdiagrams,acommon ground
is requiredon:
aThe pilot burner mounting bracket, and bThe
GND(BURNER)terminalontheignition
module. Failure to use the GND(BURNER) terminal
may result in intermittent loss of spark and/or loss of
flame current sensitivity.
2. Make sure the transformer has adequate VA.The
ignition module requires at least 0.1 A at 24 Vac.Addthe
currentdrawsofallotherdevicesin the control circuit,
including the pilot and main valves in the gas control,
and multiply by 24 to determine the total VA requirement
of these components.Addthis totalto2.4VA (fortheigni-
tion module). The result is the minimum trans- former VA
rating. Use a Class II transformer if replacement is
required.

GAS LEAK TEST (DOWNSTREAM OF GAS
CONTROL)
Paint the gas control gasket edges and all pipe
connections downstream of the gas control,
including the pilot tubing connections, with a rich
soap and water solution. Bubbles indicate gas
leaks. Tighten the joints and screws or replace
component to stop gas leak. Recheck with soap
and water solution.

temperature. Make sure the main burner and

OPERATION
Module operation can be conveniently divided into two
phases fortheS8600andS8610and threephasesforthe
S8670.
The phases are:
• Prepurge (S8670 models only)—See Fig. 10
• Trialfor ignition(allmodels)
• Mainburner operation (all models)
Fig. 9-10 summarize the normal operating sequences of
all the models.
Prepurge (S8670 models Only)
When an S8670 model is used in a fan-assisted
combustionsystem, the combustion air blower starts ona
call for heat. On proof of airflow, the air proving switch
closesandenergizestheS8670.Whenthismodelisused
in an atmospheric system, the “Call for Heat” energizes
themodule.
Ineither case, the module first initiates a 30second delay
to allow system prepurge. After prepurge, the module
starts the trialfor pilotignition sequence.
Trial for Pilot Ignition
On a “Call for Heat” (and after prepurge on S8670
models), the module energizes the spark source and the
pilot valve relay simultaneously. The pilot valve opens,
allowing gas to flow to the pilot burner for the ignition trial
time. The spark lights the pilot flame when pilot gas is
present.Aflamerectificationcircuitconfirmsthepresence
of the pilot flame, shuts off the spark source, and
energizes the main valve relay.
The S8600 family uses a two-level pilot flame proving
sequence. When a sufficient flame current is sensed, the
spark is turned OFF. However, the pilot flame must
generate a higher level of flame current to energize the
main valve. This approach assures a stable pilot flame to
support reliable burner lightoff. If the pilot flame is weak or
unstable, the spark may turn back ON. However, the trial
for pilot ignition will not exceed the stated ignition trial time
Main Burner Operation
When the main valve opens, gas flows to the main burner
where it is lit by the pilot flame. There is a short flame
stabilization period as the main valve opens to allow the
pilot flame to stabilize as the main gas lights. The system
isnowin therun modewith thepresence ofthe pilot flame
continuously monitored by the flamerectification circuit. If
the pilot flame goes out, the control senses loss of pilot
flame and shuts off both the pilot valve relay and the main
valverelay. Flowofgas topilotandmainburnersstops as
the valvesclose.
FAILED TRIAL FOR PILOT
IGNITION
Lockout Models—S8600B,H; S8610B,H;
S8670D,J
Lockout models provide a single trial for pilot ignition
sequence. If the pilot flame is not lit and sensed before
the end of the ignition trial time, the control shuts off the
pilotvalve(100%shutoff)andgoestolockout.Thecontrol
remains in lockout until power to the control is cycled by
the system thermostat or by removing and restoring
systempower.
Continuous Retry Models—S8600C,M;
S8610C,M; S8670E,J
Continuousretrymodelsprovidemultipletrialsforignition.
If the pilot is not lit or sensed before the end of the trial for
ignition time, the control shuts off the spark and pilot gas
(100% shutoff). There is a 5 minute delay before another
ignition sequence is initiated. The pattern of ignition
sequence followedbya 5minute delaycontinues until the
pilot lights and is proved or the “Call for Heat” ends. The 5
minute delay time can bebypassed by cycling the system
thermostat orremovingandrestoring systempower.
