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 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.
CAUTION
Electrical Shock or Equipment Damage.
Can shock individuals or short equipment
circuitry.
1.
Never apply a jumper across or short the
thermostat, 24V hot or 24V common terminal
in the SV9401/SV9402/SV9403, SV9501/
SV9502/SV9503, or SV9601/SV9602 wiring
harness. This can burn out the heat anticipa-
tor in the thermostat or damage the system
transformer.
2.
Never short the electronic fan timer (EFT)
output. This can damage the EFT drive
circuitry.
IMPORTANT
These ignition system controls are shipped with
protective seals over the inlet and outlet tappings.
Do not remove the seals until ready to connect
the piping.
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.
1.
Do NOT attempt to convert step-opening
models (SV9401P/SV9402P/SV9403P,
SV9501P/SV9502P/SV9503P, or SV9601P/
SV9602P).
2.
Always change the main and pilot burner
orifices when converting from natural to LP
gas or from LP to natural gas. Follow appli-
ance manufacturer specifications and
instructions to assure proper appliance
conversion.
3.
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.
Convertible (Natural/LP) Regulator for
Mobile Home Applications
Ignition system controls with suffix letter R are convertible
pressure regulator models. They can be converted from
natural gas to LP or from LP to natural gas without a
conversion kit.
Before converting the ignition control from one gas to
another, check the ignition control label and the appliance
manufacturer rating plate to determine if the factory-set
pressure regulator setting meets the appliance manifold
requirements after conversion.
NOTE: Convertible pressure regulator models (suffix
letter R) do not have field-adjustable regulators.
If the factory pressure regulator setting meets the appli-
ance manifold requirement, convert the ignition control
using the following procedure:
1. Remove the pressure regulator cap. See Fig.
2. Turn over the cap so the letters facing up are for the
gas type the appliance uses—NAT for natural gas
and LP for LP gas.
3. Replace the cap and tighten firmly.
Install Adapters on Control
IMPORTANT
3/4 in. inlets and outlets do not accommodate
flange adapters.
If adapters are being installed on the control, mount them
as follows:
Flanges
1. Choose the appropriate flange for your application
as listed in Table 5.
2. Remove the seal over the ignition system control
inlet or outlet.
