Connect Ignition Cable
Use Honeywell ignition cable or construct an ignition
cable that conforms to suitable national standards such as
Underwriters Laboratories Inc. See Tables 2 and 3.
NOTE: When using an S8610 or S8670 to replace an S86,
use the enclosed adapter to convert the S86 ignition
cable to an S8610 ignition cable. Then, install adapter
and cable to the S8610 ignition module.

Cable must be no longer than 36 in. [0.9 m]. To construct
a cable, fit one end of ignition cable with 1/4 in. diameter
Rajah connector receptacle and the other with a 1/4 in.
female quick-connect. Protect both ends with insulated
boots.
NOTE: The cable must not run in continuous contact with a
metal surface or spark voltage will be greatly reduced.
Use ceramic or plastic standoff insulators as required.
To install:
1.
Connect one end of the cable to the male quick
connect SPARK terminal on the ignition module.
2.
Connect the other end of the cable to the igniter or
igniter-sensor stud on the pilot burner/igniter-sensor.
Connect Vent Damper
The D80B Vent Damper can be used with all ignition
modules, although the Molex plug provided on some mod-
ules simplifies wiring connections when used with the D80D
Plug-In Vent Damper.
Once a module with vent damper
plug has powered a vent damper circuit, it cannot be used
in a gas system without a vent damper
. A non-replaceable
fuse in the module blows on initial power-up. Once this fuse
has blown, the module won’t work unless the vent damper
is connected.
To connect the plug-in model to D80D:
1.
Remove the plug from the terminal strip on the ignition
module case and discard.
2.
Using the wiring harness supplied, insert the matching
pin plug into receptacle on case and other end to vent
damper.

Ground Control System
The igniter, flame sensor, and ignition module must
share a common ground with the main burner. Use thermo-
plastic insulated wire with a minimum rating of 105
°
C
[221
°
F] for the ground wire; asbestos insulation is not
acceptable. If necessary, use a shield to protect the wire
from radiant heat generated by the burner. Connect the
ground wire as follows:
1.
Fit one end of the ground wire with a female 1/4 in.
quick-connect terminal and connect it to the male quick-
connect GND(BURNER) terminal on the ignition module.
2.
Strip the other end of the wire and fasten it under the
igniter bracket mounting screw. If necessary, use a shield
to protect the ground wire from radiant heat.
3.
The burner serves as the common grounding area. If
there is not good metal-to-metal contact between the burner
and ground, run a lead from the burner to ground.
NOTE: “Earth” ground is not required.
To connect the D80B, follow the wiring diagrams sup-
plied with the vent damper or see Fig. 8 for typical connec-
tions.
Connect Ignition Module
1.
Connect remaining system components to the ignition
module terminals as shown in the appropriate wiring dia-
gram, Figs. 2 through 11.
•
Fig. 2 is a basic circuit for a heating only atmos-
pheric burner with S8610F,H or S8670D.
•
Fig. 3 shows S8610F,H with vent damper plug in
a heating only atmospheric burner system with
D80D Vent Damper.
Never
use a vent damper in
an LP gas system or in a fan-assisted combustion
system.
•
Figs. 4 and 5 show S8610A,B with separate
sensor and igniter, with and without the D80D
Vent Damper.
•
Figs. 6 through 11 show S8610F,H and S8670D in
a variety of systems with alternate connections for
modules with vent damper plug. Remember, how-
ever, that a vent damper should not be used in an
fan-assisted combustion system or an LP gas
system and that the vent damper plug must not be
removed except to connect the module to a D80D
with the plug-in cable. S8610A,B can be substi-
tuted in these drawings by simply connecting the
igniter and sensor as shown in Figs. 4 and 5.
2.
Refer to heating appliance manufacturer’s instruc-
tions for wiring auxiliary controls.
3.
Adjust thermostat heat anticipator to match system
current draw. The current draw equals the total current
required for the ignition module (0.2 A) plus the gas control
and any other auxiliary equipment in the control circuit.
Connect Gas Control
Use No. 18 gauge solid or stranded wire. Use 1/4 in.
female quick-connects for module connections. Connect to
gas control terminals as shown in wiring diagrams, using
terminals appropriate to the gas control.

IMPORTANT
1.
As shown in the wiring diagrams, a common
ground is required on:
a.
The pilot burner mounting bracket, and
b.
The GND(BURNER) terminal on the ignition
module. Failure to use the GND(BURNER) termi-
nal 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 0.2 A at 24 Vac.
Add the current draws of all other devices in 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.
Add this total to 4.8 VA (for the ignition module).
The result is the minimum transformer VA rating.
Use a Class II transformer if replacement is re-
quired.
MOUNT THE SYSTEM CONTROLS
Mount any required controls, such as the gas control,
spark igniter, flame sensor, thermostat, limit, and trans-
former according to manufacturer’s instructions.
WIRE THE SYSTEM
CAUTION
1.
Check the wiring diagram furnished by the ap-
pliance manufacturer, if available, for circuits dif-
fering from the wiring hookups shown. Carefully
follow any special instructions affecting the gen-
eral procedures outlined below.
