APPLICATION
The SUPER TRADELINE
®
S8610U Universal
Intermittent Pilot Gas Ignition Control Module is designed
to provide easy field replacement of a wide range of
intermittent pilot ignition modules manufactured by
Honeywell, Robertshaw, Johnson Controls, and others.
The S8610U control 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 15 seconds or longer
• Prepurge configurable to 30 seconds or no prepurge
• Pilot burners with flow rates of 1,500 Btuh or less
• With or without integral damper connector
Table 1 describes the key features of the S8610U
control.
WARNING
Check Table 2 on page 2 before replacing an
existing intermittent pilot control with the S8610U.
If the existing control is not listed, do not use the
S8610U to replace it unless you are certain the
specifications match those of the existing control.
A complete list of the specific Honeywell and other
modules that the SUPER TRADELINE
®
S8610U is
designed to replace is provided in Table 2 on page 2.
The SUPER TRADELINE
®
S8610U 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 control module.
It also help assure proper marking of the wires attached
to the existing control and a label with LED code
information that can be affixed in the appliance.
IMPORTANT
The S8610U control module is
not
designed to
replace controls with:
— Flame sensing other than by flame rectification
(White Rodgers Cycle-Pilot
®
, or Robertshaw
thermal sensing)
— Standing pilot appliances
— Direct main burner ignition
The S8610U provides:
• Natural or LP gas
• Pilot burner ignition using an internally generated high
voltage spark
• Flame rectification circuit to monitor flame presence
• Monitoring of 24 Vac, pilot, and main gas valve
• Two LED indicators for flame presence/strength and
system status/errors
• EnviraCOM™ communication protocol for system
diagnostics
• Vent Damper connection
The S8610U is designed for a wide variety of natural or
liquid propane fueled applications.

•
If established flame is lost, trial for
ignition restarts immediately.
•
If pilot fails to light, pilot gas and spark
Off (100% shutoff). After 5 minute delay,
a new trial for ignition is initiated. This
sequence continues until lightoff or “Call
for Heat” is removed.
Included for use as
needed.

If initially installed
and powered up
with damper
attached, unit
must always have
a vent damper
connected.
