V4297S NORMALLY OPEN VENT VALVE

65-0244

6

Valve Leak Test

This is a test for checking the closure tightness of the gas
valve. It should be performed only by trained, experienced,
flame safeguard control technicians during the initial startup
of the burner system, or whenever the valve is replaced.

1. Energize the V4297S to close the vent connection.
2. Close the manual gas cock downstream of the second

Safety Shutoff Valve (SSOV).

3. Turn on main gas and make sure the gas reaches the

V4297S (energize the first SSOV).

4. Check the V4297S for gas leaks using a gas leak

detector or a soap solution.

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 close when the thermostat or controller
is calling for heat:

1. Check for line voltage at the valve lead wires or terminal

block.

2. If there is no voltage at the valve lead wires 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 lead wires 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 close, check for normal gas pressure.

5. If the valve still does not close, replace the valve.

If the valve does not open 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 opens 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.

SERVICE INFORMATION

WARNING

Explosion and Electrical Shock Hazard.
Can cause explosion, serious injury or death.
1. Turn off the gas supply and disconnect all electrical
power to the valve before servicing.

IMPORTANT

Only trained, experienced flame safeguard control
technicians should attempt to service or repair flame
safeguard controls and burner assemblies.

Scheduled Inspection and Maintenance

Set up and follow a schedule for periodic inspection and
maintenance, including the burner, all other controls, and the
valve(s). It is recommended that the valve leak test in the
Checkout section be included in this schedule. Refer to the
instructions for the primary safety control(s) for more
inspection and maintenance information.
