REVIEW THE INSTALLATION

WARNING
FIRE OR EXPLOSION HAZARD.
CAN CAUSE PROPERTY DAMAGE, SEVERE
INJURY, OR DEATH.
Follow these warnings exactly:
1. Review the installation as outlined in this section.
2. Plan for frequent maintenance as described in the
Maintenance section.
When hot surface ignition systems are used on central heating
equipment in barns, greenhouses, and commercial properties
and on heating appliances such as commercial cookers,
agricultural equipment, industrial heating equipment and pool
heaters, heavy demands are made on the controls. Special
steps may be required to prevent nuisance shut-downs and
control failure due to frequent cycling, and severe
environmental conditions related to moisture, corrosive
chemicals, dust or excessive heat. These applications require
Honeywell Home and Building Control Engineering 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 only three to four times an hour during the
heating season. In year-around applications with greater
cycling rates, the control can wear out more quickly. Perform a
monthly checkout.

Water or Steam Cleaning
If a module or gas control gets wet, replace it. If the appliance
is likely to be cleaned with water or steam, cover the controls
and wiring to protect from water or steam flow. Mount the
controls high enough above the bottom of the cabinet to avoid
getting wet during normal cleaning procedures. A NEMA 4
enclosure is recommended for the ignition module.
High Humidity or Dripping Water
Dripping water can cause 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 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 module.
Corrosive Chemicals
Corrosive chemicals can attack the module and gas control,
eventually causing a failure. If chemicals are used for routine
cleaning, avoid contact with the controls. Where chemicals are
suspended in air, as in some industrial or agricultural
applications, A NEMA 4 enclosure is recommended for the
ignition 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 module and the gas control to limit
contamination. A NEMA 4 enclosure is recommended for the
ignition module.
