S8610U
Universal Intermittent Pilot Module
SUPER TRADELINE®
INSTALLATION INSTRUCTIONS
APPLICATION
The SUPER TRADELINE® S8610U Universal Replace
ment Ignition Module is designed to provide easy field
replacement of a wide range of intermittent pilot ignition
modules manufactured by Honeywell, Robertshaw,
Penn-Johnson and others. The S8610U module provides
ignition sequence, flame monitoring, and safety shutoff
for intermittent pilot central furnaces, residential boilers,
and other heating appliances. The S8610U replaces
existing flame rectification type intermittent pilot ignition
modules with the following characteristics:
• Single rod (local sense) or two rod (remote sense)
flame sensing.
• Non-100 percent shutoff, 100 percent shutoff/lockout,
or 100 percent shutoff/continuous retry.
• Natural or LP gas.
• Shutoff/lockout times of 30 seconds or longer.
• Prepurge times of four seconds or shorter.
• Pilot burners with flow rates of 1500 Btuh or less.
• With or without vent dampers.
A WARNING
Check Table 1 before replacing an existing
intermittent pilot module with the S8610U. If the
existing module is not listed, do not use the
S8610U to replace it unless you are certain the
specifications of the S8610U match those of the
existing module.
A complete list of the specific Honeywell and other
modules that the SUPER TRADELINE® S8610U is
designed to replace is provided in Table 1.
The S8610U SUPER TRADELINE® package contains
complete, easy-to-use instructions, plus the accessories
required to adapt the existing spark cable (Rajah, stud,
nail, or other) to the spark terminal on the S8610U. It also
provides labels to help assure proper marking of the wires
attached to the existing module.
The S8610U SUPER TRADELINE® Universal Module is
not designed to replace controls with the following
characteristics:
• Flame sensing other than by flame rectification (White
Rodgers Cycle-Pilot®, or Robertshaw thermal sensing).
• Flame rectification modules with shutoff/lockout times
of less than 30 seconds, prepurge times of more than 4
seconds, or pilot burners larger than 1500 Btuh.
• Standing pilot appliances.
Honeywell provides additional control packages to
accomplish these replacements. See the Honeywell
Electronic Ignition Service Manual, form 70-6604, or call
your Honeywell wholesaler.
SPECIFICATIONS
Electrical Ratings:
Voltage: 24V, 60 Hz.
Current Draw: 1A pilot valve, 2A main valve.
Valve Contact Rating: 0.2A.
Trial For Ignition:
90 seconds maximum, then 100 percent shutoff (pilot and
main gas).
Continuous Retry:
Five-minute minimum (six-minute nominal) delay if pilot
fails to light during trial for ignition. After delay, trial for
ignition is repeated. This sequence (trial, delay, trial, delay)
continues until pilot lights or call for heat ends.
Flame Failure Response Time:
0.8 sec max at 1.0 uA flame current.
Ambient Operating Temperature:
-40°F to 165°F (-40°C to 74°C). (If main valve current is 1A
or less, 175°F (79°C) maximum ambient applies.)
