SV9510/SV9520 SMARTVALVE™ SYSTEM CONTROLS

69-2014

WARNING

Electrical Shock Hazard.
Can cause severe injury, death, or property 
damage.

Disconnect power supply before wiring to prevent 
electrical shock or equipment damage.

IMPORTANT

Always install a sediment trap in gas supply line 
to prevent contamination of ignition system 
control.

CAUTION

Equipment Damage Hazard.
Improper wiring can damage equipment.

Never apply a jumper across or short the 
thermostat, 24V hot or 24V common terminal in 
the SV9510/SV9520 wiring harness. This can 
burn out the heat anticipator in the thermostat or 
damage the system transformer.

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.

Always change the main burner orifices when 
converting from natural to LP gas or from LP to 
natural gas. Follow appliance manufacturer 
specifications and instructions.

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 (SV9510M,H/ SV9520M,H, K) 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. 

Two-stage ignition system controls (those with N and Q 
suffix letters) can be converted using a conversion kit 
(ordered separately). Order part number 396021 to 
convert from natural (manufactured) to LP gas; order part 
number 396025 to convert from LP to natural 
(manufactured) gas.

IMPORTANT

Ignition system controls with step-opening 
regulators (SV9510P/SV9520P) CANNOT be 
field-converted to LP or natural gas.

Install Adapters To Control

If adapters are being installed on the control, mount them 
as follows:

Flanges

1.

Choose the appropriate flange for your application.

2.

Remove the seal over the ignition system control 
inlet or outlet.

3.

Make sure that the O-ring is fitted in the groove of 
the flange. If the O-ring is not attached or missing, 
do not use the flange.

4.

With the O-ring facing the ignition system control, 
align the screw holes on the ignition system control 
with the holes in the flange. Insert and tighten the 
screws provided with the flange. See Fig.1. Tighten 
the screws to 25 inch-pounds of torque to provide a 
gas-tight seal.

Fig. 1.  Firmly fasten flange to valve, but do not 

overtighten screws.

Bushings

1.

Remove the seal over the ignition system control 
inlet or outlet.

2.

Apply a moderate amount of good quality pipe 
compound to the bushing, leaving two end threads 
bare. On an LP installation, use compound resistant 
to LP gas. Do not use Teflon tape.

3.

Insert the bushing in the ignition system control and 
carefully thread the pipe into the bushing until tight.

Complete the instructions below for installing the piping, 
installing the control, and connecting the wiring. Make 
sure the leak test you perform on the control after 
completing the installation includes leak testing the 
adapters and screws. If you use a wrench on the valve 
after the flanges are installed, use the wrench only on the 
flange, not on the control. See Fig. 5.

Location

The SV9510/SV9520 is mounted in the appliance 
vestibule on the gas manifold.
