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 or power burner
equipment. Meets ANSI Z21.71 standard for automatic
intermittent pilot ignition systems for field installations.

FEATURES

• Y8610U kits can be used with either natural or LP gas.
• Y8610U provides a 90 second maximum ignition trial,
shuts off, waits six minutes nominal, then reinitiates
the pilot ignition sequence. The ignition trial, shutoff,
and wait cycle repeat until the pilot lights or the call
for heat ends.
• Y8610U kits can be used with either natural or LP gas;
it provides timed trial for ignition and 100 percent pilot
shutoff on loss of flame.

MODULE
• Uses rectification principle for flame sensing.
• Provides 13 kV peak capacitive discharge spark
output (at 25 pF load).
GAS CONTROL
• Straight through body pattern.
• VR8304M capacity at 1 in. wc pressure drop (0.25 kPa
pressure drop 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.
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.
