PLANNING THE INSTALLATION
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
1. Plan the installation as outlined below.
2. Plan for frequent maintenance as described in
the Maintenance section.
Intermittent pilot systems are used on a wide variety of
central heating equipment and on heating appliances
such as commercial cookers, agricultural equipment,
industrial heating equipment and pool heaters. Some of
these applications may 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 situations, special steps may be
required to prevent nuisance shutdowns and premature
control module failure. These applications require special
Honeywell review; contact your Honeywell Sales
Representative for assistance.
Review the following conditions that can apply to your
specific installation and take the precautionary steps
suggested.
Frequent Cycling
These controls are designed for use on appliances that
typically cycle three to four times an hour only during the
heating season. In year-round applications with greater
cycling rates, the control module can wear out more
quickly; perform a monthly checkout.
Water or Steam Cleaning
If the control module gets wet, replace it. If the appliance
is likely to be cleaned with water or steam, protect (cover)
the controls and wiring from water or steam flow. Mount
the controls high enough above the bottom of the cabinet
so they do not get wet during normal cleaning procedures.
Use a NEMA 4 enclosure for the ignition control module.
High Humidity or Dripping Water
Dripping water can cause the control 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 fail.
If the appliance is in a humid atmosphere, make sure air
circulation around the controls is adequate to prevent
condensation. Also, regularly check out the system. A
NEMA 4 enclosure is recommended for the ignition
control module.
Corrosive Chemicals
Corrosive chemicals can attack the ignition control
module and gas control, eventually causing a failure. If
chemicals are used for routine cleaning, make sure they
do not reach the controls. Where chemicals are
suspended in air, as in some industrial or agricultural
applications, use a NEMA 4 enclosure for the ignition
control module.
Dust or Grease Accumulation
Heavy accumulations of dust or grease can cause
controls to malfunction. Where dust or grease can be a
problem, provide covers for the ignition control module
and the gas control to limit contamination. A NEMA 4
enclosure is recommended for the ignition control module.
Heat
Excessively high temperatures can damage controls.
Make sure the maximum ambient temperature at the
control module does not exceed the rating of the control
module. If the appliance operates at very high
temperatures, use insulation, shielding, and air
circulation, as necessary, to protect the controls. Proper
insulation or shielding should be provided by the
appliance manufacturer; verify proper 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 hazard-
ous condition.
2.
Check the ratings given in these instructions to
make sure the S8610U module is suitable for your
application.
3.
Installer must be a trained, experienced service
technician.
4.
After installation is complete, check out operation
as provided in these instructions.
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
1. The ignition control module can malfunction if it
gets wet, leading to accumulation of explosive
gas.
— Never install where water can flood, drip or
condense on the ignition control module.
— Never try to use an ignition control module
that has been wet; replace it.
2. Liquefied petroleum (LP) gas is heavier than air
and will not naturally vent upward.
— Do not operate electric switches, lights, or
appliances until you are sure the appliance
area is free of gas.
WARNING
Electrical Shock Hazard.
Can cause severe injury, death or property
damage.
Disconnect power supply before beginning wiring
or making wiring connections to prevent electrical
shock or equipment damage.
