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

— 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 ft3/hr (7.6 m3/hr)
• VR8204A capacity with or without 1/2” x 3/4” adapter is 150 ft3/hr (4.2 m3/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
