Field testing oil valves
Always disconnect power source
before wiring to avoid electrical
shock or damage to electrical com-
ponents.
Checking SVC-10FF coil resistance
• You can determine whether the oil valve
coil is normal by measuring the resis-
tance across the coil.
• Disconnect power to the burner. Then
disconnect one of the oil valve wires in
the junction box.
• Measure the resistance from one coil
wire to the other. If the coil is good, the
resistance should be between 494 and
526 ohms. If not, replace the oil valve.
Check A2VA-3006 oil valve coil resistance
• You can determine whether the oil valve
coil is normal by measuring the resis-
tance across the coil.
• Disconnect power to the burner. Then
remove the power lead to the A2VA-3006
coil.
• Measure
the resistance
between the
bottom two
terminals
of the
coil. The
resistance
should be be-
tween 350 and
550 ohms. If not,
replace the oil valve.

Application tips
1. Carlin solenoid oil safety shut-off
valves help to provide years of safe,
effi cient oil burner performance
while adding reliability to the burner
and oil delivery system.
2. Carlin’s SVC oil valves are direct-act-
ing, two-way, normally-closed. Use
on single or two-pipe oil systems to
isolate the fuel pump, preventing the
possibility of oil tank siphoning.
3. Carefully review the burner instruc-
tion manual when applying to en-
sure the oil valve is correctly wired
and the burner fuel lines are cor-
rectly installed.
