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
Gas Control Valve
• Straight through body pattern
• VR8304M capacity is 270 ft
3
/hr (7.6 m

/hr)
• VR8204A capacity with or without 1/2” x 3/4” adapter is
150 ft
3
/hr (4.2 m
3
/hr)
• Manual ON-OFF valve blocks gas flow into the gas control
when in the OFF position
• Two main automatic valves: one solenoid-operated, and
one a servo-operated diaphragm system
Igniter-Sensor
• Single electrode made of Kanthal provides both ignition
and flame sensing
• Rated for 1775°F (968°C) at electrode tip; 1250°F (677°C)
at ceramic insulator
