PLANNING THE INSTALLATION

WARNING
Fire or Explosion Hazard.
Can cause product damage, severe injury,
or death.
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 contamina-
tion.
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.
