PLANNING THE INSTALLATION
Intermittent pilot systems are used on various types of central
heating equipment and on heating appliances such as
commercial cookers, agricultural equipment, industrial
heating equipment, and pool heaters. Some of these
applications can make heavy demands on the controls, either
because of frequent cycling or because of moisture, corrosive
chemicals, dust, or excessive heat in the environment. In
these applications, special steps could be required to prevent
nuisance shutdowns and premature control failure. These
applications require Honeywell Home and Building Control
Engineering review; contact your Honeywell Sales
Representative for assistance.
Frequent Cycling
These controls are designed for use on space heating
appliances that typically cycle three to four times an hour
during the heating season and not at all during the cooling
season. In applications with significantly greater cycling rates
and longer heating seasons, we recommend monthly
checkout because the controls can wear out more quickly.
Water or Steam Cleaning
Once a module or gas control has been wet, it can operate
unreliably and must be replaced. If the appliance is cleaned
with water or steam, the controls and associated wiring
should be covered so water or steam flow cannot reach them.
The controls should be high enough above the cabinet
bottom so flooding or splashing water can not reach them
during normal cleaning procedures. If necessary, shield the
controls to protect them from splashing water. A NEMA 4
enclosure is recommended for the ignition module; see the
Electronic Ignition Service Manual, form 70-6604.
High Humidity or Dripping Water
Over time, dripping water or high ambient humidity can create
unwanted electrical paths on the module circuit board,
causing the module to fail. Never install an appliance where
water can drip on the controls.
In addition, high ambient humidity can cause the gas control
to corrode, and finally to fail.
When the appliance is installed in a humid atmosphere, make
sure air circulation around the module and gas control is
adequate to prevent condensation. It is also important to
regularly check out the system. A NEMA 4 enclosure could be
needed; see the Electronic Ignition Service Manual,
form 70-6604.
Corrosive Chemicals
Corrosive chemicals can also attack the module and gas
control and eventually cause a failure. Where chemicals are
used routinely for cleaning, make sure the cleaning solution
cannot reach the controls. Where chemicals could be
suspended in air, as in some industrial and agricultural
applications, protect the ignition module from exposure with a
NEMA 4 enclosure; see the Electronic Ignition Service
Manual, form 70-6604.
Dust or Grease Accumulation
Heavy accumulation of dust or grease can cause the controls
to malfunction. Where dust or grease can cause a problem,
provide covers for the module and the gas control that emit
environmental contamination. A NEMA 4 enclosure is
recommended for the ignition module; see the Electronic
Ignition Service Manual, form 70-6604.
Heat
The controls can be damaged by excessively high
temperatures. Make sure the maximum ambient temperature
at the control location does not exceed the rating of the
control. If the appliance normally operates at very high
temperatures; insulation, shielding, and air circulation could
be necessary to protect the controls. Proper insulation or
shielding should be provided by the appliance manufacturer;
make sure adequate air circulation is maintained when the
appliance is installed.
INSTALLATION
When Installing this Product…
1. Read these instructions carefully. Failure to follow them
could damage the product or cause a hazardous
condition.
2. Check the ratings given in these instructions and on the
product to ensure the product is suitable for your
application.
3. Installer must be a trained, experienced service
technician.
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 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 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.
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.
