Y8610U INTERMITTENT PILOT RETROFIT KIT
7 68-0291—03
INSTALLATION
When Installing this Product…
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous condi-
tion.
2. Check the ratings given in these instructions and on the
product to ensure the product is suitable for your applica-
tion.
3. Installer must be a trained, experienced service techni-
cian.
4. After completing installation, use these instructions to
check product operation.
IMPORTANT
1. Installer must comply with local codes and ordinances
of the National Fuel Code (ANSI Z223.1—NFPA
No. 54) and National Electrical Code (ANSI NFPA
No. 70).
2. Installer must fill in and attach label to appliance being
converted.
3. Use Y8610 Retrofit Kit only with atmospheric burners.
Do not use on direct vent appliances, appliances with
induced draft, or power burners.
4. Do not use the Y8610 Retrofit Kit with mercury pilots
or 250 to 750 mV pilot systems.
WARNING
FIRE OR EXPLOSION OR ELECTRICAL SHOCK
HAZARD CAN CAUSE PROPERTY
DAMAGE,SEVERE INJURY, OR DEATH.
Follow these warnings exactly:
1. Disconnect the power supply before wiring to
prevent electrical shock or equipment damage.
2. To avoid dangerous accumulation of fuel gas, turn
off gas supply at the appliance service valve
before starting Installation and perform the Gas
Leak Test immediately following the installation.
(See “Checkout” on page 15.)
3. Never install where water can flood, drip, or
condense on module or gas control. Never use a
module or gas control that has been wet. If wet,
controls can malfunction and lead to an
accumulation of explosive gas.
4. Do not light or operate electric switches, lights, or
appliances until you are sure the appliance area is
free of gas. Liquefied petroleum (LP) gas is
heavier than air and does not vent upward
naturally.
Maintenance Requirements in Severe
Environments
Regular preventive maintenance is important in any
application, but especially so in commercial cooking,
agricultural, and industrial applications because:
• In many such applications, particularly commercial cooking,
the equipment operates 100,000-200,000 cycles per year.
Such heavy cycling can wear out the gas control in one to
two years. A normal forced air furnace, for which the
controls were originally intended, typically operates less
than 20,000 cycles per year.
• Exposure to water, dirt, chemicals, and heat can damage
the ignition control module or the gas control and shut down
the control system. A NEMA 4 enclosure can reduce
exposure to environmental contaminants.
The maintenance program should include regular checkout of
the system as outlined under “Checkout” on page 15.
WARNING
FIRE OR EXPLOSION HAZARDCAN CAUSE
PROPERTY DAMAGE, SEVERE INJURY, OR
DEATH.
Do not attempt to disassemble or clean the module.
Improper reassembly and cleaning can cause
unreliable operation.
Maintenance frequency must be determined individually for
each application based on:
• Cycling frequency: Appliances that cycle more than 20,000
times annually should be checked monthly.
• Intermittent use: Appliances that are used seasonally
should be checked before shutdown and again before the
next use.
• Consequence of unexpected shutdown: Where the cost of
an unexpected shutdown is high, the system should be
checked more often.
• Dusty, wet, or corrosive environment: Because these
environments can cause the controls to deteriorate more
rapidly, the system should be checked more often.
Any ignition control module or gas control should be replaced if
it does not perform properly on checkout or troubleshooting. In
addition, replace any ignition control module or gas control if it
is wet or looks like it has ever been wet. Protective enclosures
as outlined under “Planning the Installation” on page 6 are
recommended regardless of checkout frequency.
Perform the Pre installation Safety
Inspection
The pre-installation checks described below must be
completed before the Y8610U Intermittent Pilot Retrofit Kit is
installed. If a condition that could result in unsafe operation is
detected, the appliance should be shut off and the owner
advised of the unsafe condition. Correct any potentially unsafe
condition before proceeding with the installation. See “Exhibit
A” on page 22.
The following safety checklist should be followed in making the
safety inspection:
1. Conduct a Gas Leakage Test of the appliance piping and
control system downstream of the shut-off valve in the
supply line to the appliance.
2. Visually inspect the venting system for proper size and
horizontal pitch and determine there is no blockage or
restrictions, leakage or corrosion or other deficiencies
which could cause an unsafe condition.
3. Shut off all gas to the appliance and shut off any other
fuel-burning appliance within the same room. Use the
shutoff valve in the supply line to each appliance. If a
manual gas valve is not in the gas supply line within 6
feet of the appliance in an accessible location, one shall
be installed.
4. Inspect burners and crossovers for blockage and corro-
sion.
