1 PRODUCT DATA Registered TrademarkCopyright 1996 honeywell Inc. All Rights Reserved68-0135-2S8610 UUniversal Intermittent Pilot ModuleAPPLICATIONThe S8610U Universal Replacement ignition Module isdesigned to provide easy field replacement of a wide range ofintermittent Pilot ignition modules manufactured byHoneywell, Robertshaw, Johnson and others. The S8610 UModule provides ignition sequence, flame monitoring, andsafety shutoff for Intermittent Pilot central furnaces, residentialboilers, and other heating Provides up to Pilot and main valve currentrating. System uses rectification principle for flame sensing. For use with separate igniter and sensor orcombination igniter-sensor. Q345, Q348, Q362, Q373or Q381 Igniter-sensor recommended as combinationigniter-sensor; Q179C with igniter and sensormounted on one bracket, or Q354 Sensor with Q345,Q348, Q362, Q373 or Q381 Igniter-sensorrecommended as separate igniter and sensor.

2 Q3450/Q3480 Hot Surface Pilot hardware plugsdirectly into system control. Can be used on natural or LP gas; provides 100percent shutoff on ignition failure. Waits six minutesnominal following shutoff, then reinitiates the pilotignition sequence. The ignition trial-shutoff-wait cyclerepeats until the Pilot lights or the call for heat ends. Replaces numerous honeywell and competitormodules. Capacitive discharge spark output. Temperature rating is -40 F to 175 F (-40 C to 79 C)when used with or less main valve; -40 F to 165 F(-40 C to 74 C) when used with to main .. 1 Features .. 1 Specifications .. 2 Ordering Information .. 2 Planning the installation .. 4 installation .. 6 Startup and Checkout .. 15 Maintenance .. 15 Operation .. 17 ANSI Standards .. 21S8610U Universal Intermittent Pilot MODULE68-0135 22 ORDERING INFORMATIONWhen purchasing replacement and modernization products from your TRADELINE wholesaler or distributor, refer to theTRADELINE Catalog or price sheets for complete ordering number, or TRADELINE order you have additional questions, need further information, or would like to comment on our products or services, please write local Home and Building Control Sales Office (check white pages of your phone directory).

With or without vent complete list of the specific honeywell and other modulesthat the SUPER TRADELINE S8610U is designed toreplace is provided in Table S8610U SUPER TRADELINE package containscomplete, easy-to-use instructions, plus the accessoriesrequired to adapt the existing spark cable (Rajah, stud, nail,or other) to the spark terminal on the S8610U . It also provideslabels to help assure proper marking of the wires attached tothe existing S8610U SUPER TRADELINE Universal Module is notdesigned to replace controls with the following characteristics: Flame sensing other than by flame rectification (WhiteRodgers Cycle- Pilot , Robertshaw thermal sensing). Flame rectification modules with shutoff/lockout times ofless than 30 seconds, prepurge times of more than fourseconds, or Pilot burners larger than 1500 Btuh.

9 Standing Pilot provides additional control packages toaccomplish these replacements. See the HoneywellElectronic ignition Service Manual, form 70-6604, or call yourHoneywell THE INSTALLATIONWARNINGFIRE OR EXPLOSION HAZARDCAN CAUSE PROPERTY DAMAGE, SEVEREINJURY OR these warnings exactly:1. Plan the installation as outlined Plan for frequent maintenance as described inthe Maintenance Intermittent Pilot systems are used on central heatingequipment in barns, greenhouses, and commercial propertiesand on heating appliances such as commercial cookers,agricultural equipment, industrial heating equipment and poolheaters, heavy demands are made on the controls. Specialsteps may be required to prevent nuisance shutdowns andcontrol failure due to frequent cycling, severe environmentalconditions related to moisture, corrosive chemicals, dust orexcessive heat. These applications require honeywell Homeand Building Control Engineering review; contact yourHoneywell Sales Representative for the following conditions that could apply to yourspecific installation and take the precautionary CyclingThese controls are designed for use on appliances thattypically cycle three to four times an hour only during theheating season only.

10 In year-round applications with greatercycling rates, the control can wear out more quickly. Performa monthly Or Steam CleaningIf a Module or gas control gets wet, replace it. If the applianceis likely to be cleaned with water or steam, protect (cover) thecontrols and wiring from water or steam flow. Mount thecontrols high enough above the bottom of the cabinet so theydo not get wet during normal cleaning procedures. Use aNEMA 4 enclosure for the ignition Module ; see the ElectronicIgnition Service Manual, form Humidity or Dripping WaterDripping water can cause the Module to fail. Never install anappliance where water can drip on the addition, high ambient humidity can cause the gas controlto corrode and the appliance is in a humid atmosphere, make sure aircirculation around the controls is adequate to preventcondensation. Also, regularly check out the system. A NEMA4 enclosure is recommended for the ignition Module ; see theElectronic ignition Service Manual, form ChemicalsCorrosive chemicals can attack the Module and gas control,eventually causing a failure.
