Recommended Preparation
• Examine the SV-(DLE) for shipping damage.
• The main gas supply must be shut off before
installing the valve.
• The inside of the SV-(DLE), the flange, and piping
must be clean and free of dirt and debris before installing.
Failure to remove dirt and debris could result in valve
damage and/or improper performance.
Flange Mounting Procedure
• Verify that the o-ring and the groove is clean and in
good condition on the outlet side of the valve.
• Install the SV-(DLE) with the gas flow matching the
direction indicated by the arrows on the casting.
• Mount the SV-(DLE) with the solenoid vertical upright to
horizontal.
• Clean the mounting surface of the flange.
• Attach the flange to the outlet of the SV-(DLE) using the
screws supplied.
• Use a 4mm Allen wrench for the M5 screw.
SV / SV-DLE1005 & 1007
• Use a 5mm Allen wrench for the M6 screw.
SV / SV-DLE 1010, 1012
• Use a 6mm Allen wrench for the M8 screw.
SV / SV-DLE 1015, 1020
• Tighten the screws in a crisscross pattern
• Do not overtighten the screws. Follow the maximum
torque values below.

•
It is not recommended that this valve be painted. Paint-
ing covers date codes and other labels that identify this
valve.
•
If the valve needs to be painted, a paint free of volitile
organic componants (VOC's) must be used. VOC's can
damage valve o-rings, resulting in external gas leakage
over time.
•
Radiant heat must be considered as a heat source that
could result in an ambient temperature higher than the
rating of this valve.

Recommended Piping Procedure
• Use new, properly reamed and threaded pipe.
• Apply good quality pipe sealant, putting a moderate
amount on the male threads only. If pipe sealant lodges
on the valve seat, it will prevent proper operation. If using
LP gas, use pipe sealant rated for use with LP gas.
• Do not thread pipe too far. Valve distortion and/or mal-
function may result from excess pipe in the valve body.
• Apply counter pressure with a parallel jaw wrench only to
the flats on the flange when connecting to pipe.
• Do not overtighten the pipe. Follow the maximum torque
values listed below.

• After installation, perform a complete leak test using a
soapy solution. The presence of bubbles indicates a leak.
If the flow is not in the same direction of the arrows
on the valve body, the valve will not
operate properly.
•
During the painting process, use measures that will allow
the valve's date code and other labeling information to be
legible after the paint is dry.
•
Provide propor shielding to protect against radiant heat.
