PLANNING THE INSTALLATION
WARNING
Fire or Explosion Hazard.
Can cause severe injury, death or property
damage.
Follow these warnings exactly:
1. Plan the installation as outlined below.
2. Plan for frequent maintenance as described in
the Maintenance section.
When intermittent pilot 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 shutdowns and control failure due to
frequent cycling, 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
This control is designed for use on appliances that
typically cycle three to four times an hour only during the
heating season. In year-around applications and
applications with greater cycling rates, the control can
wear out more quickly. Perform a monthly checkout as
described in this instruction manual.
Water or Steam Cleaning
If a control gets wet, replace it. If the appliance is likely to
be cleaned with water or steam, protect (cover) the
control and wiring from water or steam flow. Mount the
control high enough above the bottom of the cabinet so it
does not get wet during normal cleaning procedures.

High Humidity or Dripping Water
Dripping water can cause the control to fail. Never install
an appliance where water can drip on the control. In
addition, high ambient humidity can cause the control to
corrode and fail. If the appliance is in a humid
atmosphere, make sure air circulation around the control
is adequate to prevent condensation. Also, regularly
check out the system as described in this instruction
manual.
Corrosive Chemicals
Corrosive chemicals can attack the control, eventually
causing a failure. If chemicals are used for routine
cleaning, avoid contact with the control. Where
chemicals are suspended in air, as in some industrial or
agricultural applications, protect the control in an
enclosure.
Dust or Grease Accumulation
Heavy accumulations of dust or grease can cause the
control to malfunction. Where dust or grease can be a
problem, provide covers for the control to limit
contamination.
Heat
Excessively high temperatures can damage the control.
Make sure the maximum ambient temperature at the
control does not exceed the control rating. If the
appliance operates at very high temperatures, use
insulation, shielding, and air circulation, as necessary, to
protect the control. The appliance manufacturer should
provide proper insulation or shielding; verify proper air
circulation is maintained when the appliance is installed.
