PLANNING THE INSTALLATION

WARNING
Fire or Explosion Hazard.
Can cause property 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.
Heavy demands are made on the controls when direct
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.
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 Combustion Engineering
review; contact your Honeywell Sales Representative for
assistance.
Review the following conditions that can apply to your
specific installation and follow the precautions 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 with greater
cycling rates, the control can wear out more quickly.
Perform a monthly checkout.
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.

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 with an enclosure.
