Corrosive Chemicals; Installation - Honeywell SmartValve SV9540 Installation Instructions Manual

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.

SV9540; SV9640 SmartValve™ SYSTEM CONTROLS
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 completion of installation.
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 gas supply
line to prevent contamination of ignition
system control.
WARNING
LINE VOLTAGE
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH.
Never apply a jumper across or short any of the
terminals in the SV9540; 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.
Converting Ignition System Control
from Natural Gas to LP Gas Application
(or LP Gas to Natural Gas Application)
WARNING
FIRE OR EXPLOSION HAZARD
CAN CAUSE PROPERTY DAMAGE,
SEVERE INJURY OR DEATH
Do NOT attempt to convert step-opening models
(SV9540P/SV9542P; SV9640P/SV9642P). Always
change the main and pilot burner orifices when
converting from natural to LP gas or from LP to
natural gas. Follow appliance manufacturer
specifications and instructions carefully to assure
proper appliance conversion.
Ignition system controls are factory-set for natural (and
manufactured) or LP gas. Do not attempt to use an ignition
system control set for natural (manufactured) gas on LP
gas, or an ignition system control set for LP gas on natural
(manufactured) gas.
Ignition system controls with standard or slow opening
regulators (SV9540M,H; SV9640M,H) can be converted
from one gas to the other with a conversion kit (ordered
separately). Order part no. 393691 to convert from natural
(manufactured) to LP gas; order part no. 394588 to
convert from LP to natural (manufactured) gas.
IMPORTANT
Ignition system controls with step-opening
regulators (SV9540P; SV9640P) CANNOT be
field-converted to LP or natural gas.
