S8610U UNIVERSAL INTERM ITTENT PILO T MODULE

Perform Preinstallation Safety Inspection

The preinstallation checks described in ANSI Standard
Z21.71 in Exhibit A must be done before the replacement
module is installed. If a condition that could result in unsafe
operation is detected, the appliance should be shut off and
the owner advised of the unsafe condition. Correct any
potentially unsafe condition before proceeding with the
installation.

Remove Old Module

Disconnect power supply before doing any work on the
unit. Disconnect and tag the wires from the old module
using the wire labels provided. Remove the old module
from its mounting location.

Mount New Ignition Module

W e recommend mounting the S8610U Module in the
same location as the old module, if possible. Otherwise,
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 in the Application section.
Mount the module with the terminals down to protect
them from dripping water and dust. The module can also
be mounted with the terminals on either side. Do not
mount w ith the terminals pointing up. Refer to Fig. 1 for
mounting recommendations. When it is necessary to drill
new mounting holes, use the S8610U as a template to
mark mounting hole pattern. Drill new holes, as required.
Fasten securely with four No. 6-32 machine or No. 8
sheetmetal screws.

Wire the Module

A CAUTION
1. Check the wiring diagram furnished by the
appliance manufacturer, if available, and
compare with Tables 3 through 6. Carefully
follow any special instructions affecting the
general wiring procedures outlined below.
2. Disconnect the power supply before making
wiring connections to prevent electrical shock
or equipment damage.

O Connect the wires to the S8610U Ignition Module as
shown in Tables 3 through 6. Make sure that
adequate system ground is provided as indicated in
the wiring tables.
0 Verify the thermostat anticipator setting as explained
in the Important.
NOTE: The wiring diagrams in Fig. 2 through 4 show
typical hookups with the S8610U Ignition Module
and should be used for reference only.
MOUNT IN ONE OF THESE POSITIONS
DO NOT MOUNT
WITH TERMINALS FACING UP
Fig. 1. Module mounting recommendations.
Modify Ignition Cable, If Necessary
Use existing ignition cable if it is in good condition. If the
existing ignition cable does not have a 1/4 in. quick-
connect on the module end, either use the Rajah adapter
or strip the wire and replace with the 1/4 in. insulated
quick-connect supplied. If the cable must be replaced,
order a Honeywell ignition cable, see Table 2. It might be
necessary to replace the connector at the pilot burner end
to match the pilot burner spark termination.
NOTE: When using an S8610U to replace an S86, use
the enclosed adapter to convert the S86 Ignition
Cable to an S8610U Ignition Cable. Then,
install the adapter and cable to the S8610U
Ignition Module.
