SOLENOID SAFETY SHUT-OFF VALVE

TROUBLESHOOTING

WARNING
Electrical Shock Hazard.
Can cause serious injury or death.
Use extreme caution while troubleshooting; line
voltage is present.
IMPORTANT
Do not replace the valve until all other sources of
trouble are eliminated.
Troubleshooting Procedure
If the valve does not open when the thermostat or controller
calls for heat:
1. Check for line voltage at the valve leadwires or terminal
block.
2. If there is no voltage at the valve leadwires or terminal
block, make sure:
a. line voltage power is connected to the master
switch;
b. master switch is closed and overload protection
(circuit breaker, fuse or similar device) has not
opened the power line.
3. If there is still no voltage at the valve leadwires or
terminal block, make sure all appropriate contacts in the
thermostat or controller, limits and flame safeguard
controls are closed. If one or more are open, determine
the cause(s); correct the trouble, and proceed.
4. If there is proper voltage at the valve but the valve still
does not open, check for normal gas pressure.
5. If the valve still does not open, replace the valve.
If the valve does not close when one or more of the
appropriate contacts in the thermostat, controller, limits or
flame safeguard control is open:
1. Make sure the valve is wired in the correct circuit.
2. Open the master switch to remove power from the
valve.
3. If the valve closes now, check the wiring for the valve
and correct the wiring as necessary.
4. Check for a short in the electrical circuit and repair it as
necessary.
