S8600B,C,H,M; S8610B,C,H,M; S8670D,E,J,K INTERMITTENT PILOT GAS IGNITION CONTROL
Connect remaining system components to the ignition
module terminals as shown in the appropriate wiring
diagram.
• Fig. 3 is a basic circuit for the H and M models used in
heating systems with atmospheric burners.
• Fig. 4 shows the basic circuit for the B and C models
with separate sensor and igniter in a heating system
with atmospheric burners.
• Fig. 5—8 show typical circuits for power assisted
combustion applications and two-stage gas control
with power assisted combustion applications.
MAKE FLAME SENSE CONNECTION
For B, C, J, and K models:
These models have remote flame sensing (two rod).
Connect the flame sensor wire from the Pilot burner/
igniter to the SENSE connector on the ignition module.
For H, M, D, and E models:
These models have local flame sensing (single rod). The
spark lead carries the flame signal.
CONNECT GAS CONTROL
Use 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.
GROUND CONTROL SYSTEM
The igniter, flame sensor and ignition module must share
a common ground with the pilot burner. Use thermoplastic
insulated wire with a minimum rating of 221° F (105° C) 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 BRN GND terminal on the ignition
module.
2. Strip the other end of the wire and fasten it under
the pilot burner bracket mounting screw. If neces-
sary, use a shield to protect the ground wire from
radiant heat.
3. The pilot burner serves as the common grounding
area. If there is not good metal-to-metal contact
between the pilot burner and ground, run a lead
from the pilot burner to ground.
NOTE: Earth ground is not required.
