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 gas controls 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.
Special procedures 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 Residential Thermal Solutions
Engineering review; contact your Resideo 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 hazard-
ous condition.
2.
Check the ratings given in the instructions and on
the product to make sure the product is suitable 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 the gas supply at the appliance service
valve before starting installation, and perform
Gas Leak Test after installation is complete.
3. Do not bend pilot tubing at ignition system
control or pilot burner after compression fitting
is tightened, or gas leakage at the connection
can result.
4. Always install a sediment trap in the gas supply
line to prevent contamination of the ignition
system control.
CAUTION
Electrical Shock or Equipment Damage Hazard.
Can shock individuals or short equipment
circuitry.
1. Disconnect power supply before installation.
2. Never apply a jumper across or short any of the
terminals in the SV9440, SV9540 or SV9640
wiring harness. This can damage the system
transformer or the control.
Follow the appliance manufacturer instructions, if
available; otherwise, use these instructions as a guide.
IMPORTANT
These ignition system controls are shipped with
protective seals over the inlet and outlet tap-
pings. Do not remove the seals until ready to
install adapters or connect the piping.
