Terminals may be marked 25V on some models and 24V on later models. These are functionally equivalent.
b
If 25V (2) and TH-R have wires connected, disconnect and splice together with solderless connector.
c
If TH-R and TH-W are jumpered together, connect 25V (2) lead from S86 to TH-W on S8610U.
d
On dual igniter and sensor models, remove jumper wire quick connect from S8610U Remote Sense terminal, then cut jumper wire at
circuit board and discard.
e
Leave black jumper connected.
f
Use Rajah to quick connector adapter (supplied) or cut Rajah connector off ignition cable at module end and attach insulated quick
connect for connection to S8610U.

* IMPORTANT
If the old module had a
vent damper connector but
a vent damper was not
installed, or if it did not
have a vent damper
connector, then connect
the 25V (2) or 24V wire
from the old module to the
TH-W terminal on the
S8610U. Do not use the
24V terminal on the
S8610U.
If the old module had a
vent damper, connect it to
the P1 connector on the
module, and wire the
terminals as indicated in
the table.
