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 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.
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 rating
of the control. If the appliance operates at very high
temperatures, use insulation, shielding, and air
circulation, as necessary, to protect the control. Proper
insulation or shielding should be provided by the
appliance manufacturer; verify proper air circulation is
maintained when the appliance is installed.
INSTALLATION
When Installing this Product…
1.
Read these instructions carefully. Failure to
follow them could damage the product or cause
a hazardous condition.
2.
Check the ratings given in the instructions and
on the product to make sure the product is suit-
able for your application.
3.
Installer must be a trained, experienced service
technician.
4.
After installation is complete, check out product
operation as provided in these instructions.
WARNING
Fire or Explosion Hazard.
Can cause property damage, severe injury
or death.
Follow these warnings exactly:
1. Disconnect power supply before wiring to
prevent electrical shock or equipment
damage.
2. To avoid dangerous accumulation of fuel
gas, turn off gas supply at the appliance
service valve before starting installation, and
perform Gas Leak Test after installation is
complete.
3. Always install a sediment trap in gas supply
line to prevent contamination of gas control.
4. Do not force the on-off switch. Use only your
fingers to operate the on-off switch. Never
use any tools. If the electronic on-off switch
does not operate by hand, the gas control
should be replaced by a qualified service
technician. Force or attempted repair may
result in fire or explosion.
5. Gas will leak if installed backwards.
