Y8610U Intermittent Pilot Retrofit Kit
GENERAL
The Y8610U is a complete kit for converting conventional
standing pilot systems to intermittent pilot systems. It is used
on gas-fired atmospheric furnaces, boilers, and heating
appliances. Not for use on direct vent, induced draft, or power
burner equipment. Meets ANSI Z21.71 standard for automatic
intermittent pilot ignition systems on central furnaces and
boilers.
FEATURES
Y8610U kits can be used with either natural or LP gas.
The S8610U ignition control provides a 90 second
maximum ignition trial, shuts off, waits five minutes
nominal, then re-initiates the pilot ignition sequence. The
ignition trial, shutoff, and wait cycle repeat until the pilot
lights or the call for heat ends.
Each kit includes:
S8610U Intermittent Pilot Module
VR8304M Dual Valve Combination Gas Control
or
VR8204A Dual Valve Combination Gas Control
392431 Igniter-Sensor
394800-30 Ignition Cable
393691 Natural to LP Gas Conversion Kit
Wiring Harness
393690-14 Straight Flange Kit (3/4 in.)
Reducer adapters for gas control with VR8304M
Installation hardware
Temperature Ratings:
S8610U: -40°F to 165°F (-40°C to 74°C)
VR8304M: -40°F to 175°F (-40°C to 79°C)
VR8204A: 0°F to 175° F (-18°C to 79°C)
Intermittent Pilot Gas Ignition Control Module
Uses flame rectification for flame sense
Internal spark generator lights pilot gas; main burner lights
after pilot flame lights and proves
100% shutoff of pilot and main gas if burner fails to light
Continuous retry ignition sequence prevents nuisance
lockouts
Two LEDs indicate system status and flame signal strength

and flame sensing
Rated for 1775°F (968°C) at electrode tip; 1250°F (677°C)
