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.
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.
