Automatic Ignition Systems

ANSI Z21.20

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.

• 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

— 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)

• 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

• Straight through body pattern

• VR8304M capacity is 270 ft

• 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

• 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
