Y8610U INTERMITTENT PILOT RETROFIT KIT
3 68-0291—03
Transformer Sizing:
Add current ratings of Y8610, vent damper, and any other
control system components. Multiply this total by 24V to
determine the transformer VA requirement.
Mounting:
Mounts in any position except with terminals up. Recom-
mended mounting position is with terminals down to provide
maximum protection from dripping water or dust accumula-
tion. Refer to Fig. 14 on page 12.
Fasten with No. 6-32 machine screws or No. 8 sheet metal
screws or 8-18 x 5/8 pan head tapping screws of appropri-
ate length.
Wiring Connections:
— Between the module and gas control: 30 in. (762 mm)
wiring harness with 1/4 in. quick-connect terminals.
— Between the module and the igniter-sensor: 30 in.
(762 mm) ignition cable with stud terminal and 1/4 in.
quick-connect terminal.
Terminals:
1/4 in. male quick-connects. S8610U has Molex plug for
connection to a vent damper harness. Once the S8610U
has powered a vent damper, the module works only if the
vent damper is connected.
