V4297S
Normally Open Vent Valve
APPLICATION
The V4297S provides the vent function in a double block and
bleed configuration.The valve is part of the Honeywell
Integrated Valve Train System, which allows gas train
components to be directly bolted together.
FEATURES
• Used with natural, manufactured, mixed or liquefied
petroleum (LP) gases.
• V4297S valves are normally open valves to be used as
vent valves in double block and bleed
configurations.The gas flows through the vent
connection when the valve is not energized.
• V4297S are used with 110/120Vac 50/60Hz
controllers.
• Two valve body types (small and large)
applicable to seven pipe sizes:
Small body type for 3/4 in. (19 mm), 1 in. (25 mm),
1-1/4 in. (32 mm), 1-1/2 in. (38 mm) and
2 in. (51 mm) pipes.
Large body type for 2 in. (51 mm),
2-1/2 in. (64 mm) and 3 in. (76 mm) pipes.
• Small body has a 1 in. NPT threaded vent connection.
Large body has a 1-1/4 in. NPT threaded vent
connection.
• Two 1/4 in. NPT threaded pressure taps available for
the small body valve, three for the large body valve.
• NEMA 1 enclosure standard.
• V4297S is not gas flow direction dependent. It can be
connected either way in the valve train.
• Unpainted die-cast aluminum body.

OPERATION AND CHECKOUT
Operation
The V4297S is a normally open valve.The valve closes when
it is energized, and opens when the power is removed. It
provides the vent function in a double block and bleed
application.The V4297S is open when the two Safety Shutoff
Valves (SSOV) are closed, and is closed when the two SSOV
are open.

WARNING
Explosion Hazard And Electrical Shock Hazard.
Can cause explosion, serious injury or death.
1. Do not put the system into service until you have
satisfactorily completed the following Valve Leak
Test, all applicable tests described in the Checkout
section of the instructions for the flame safeguard
control, and any other tests required by the burner
manufacturer.
2. All tests must be performed by a trained,
experienced, flame safeguard control technician.
3. Close all manual fuel shutoff valves as soon as
trouble occurs.
After the installation is completed, cycle the valve several
times with the manual fuel shutoff cock closed. Make sure the
valve functions properly.Also perform the Valve Leak Test
before putting the valve into service.

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.
