Make Flame Sense Connection
For an ignition module used in remote flame sensing
(separate igniter and sensor rods) applications, the sense
jumper wire is not used. See Fig. 2 and Table 9 on
page 11 and perform the following:
— Clip the sense jumper wire as close as possible to the
base of the ignition control module and discard the
clipped end.
— Attach the flame sensor wire from the Pilot burner/
igniter to the REMOTE SENSE connector.
For an ignition module used in local flame sensing (single
rod) applications, see Fig. 2 and Table 9 on page 11 and
perform the following:
— Attach the sense jumper wire to the REMOTE SENSE
connector.
Connect Gas Control
Use No. 18 gauge solid or stranded wire. Use 1/4 in.
female quick connects for control connections. Connect to
gas control terminals as shown in wiring diagrams, using
terminals appropriate to the gas control.
Ground the Control System
The igniter, flame sensor, and ignition control 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
control 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.
Wiring Connections
Use Fig. 2 and Table 9 to make the remaining wiring
connections. Fig. 3–Fig. 5 beginning on page 12 illustrate
typical wiring connections in heating systems with
atmospheric burners and with power-assisted
combustion.
