OEM Natural Gas Valve Less Ignition Control(Lennox)


Perform the following procedure to install the replacement VLV49A valve.

1. Turn off power to the appliance.
2. Turn off the gas at the manual shutoff valve adjacent to the appliance.
(If the manual shutoff valve services more than one appliance, be sure
to light the other pilots before leaving.)
3. With the gas and power to the appliance turned off, disconnect the
power supply (transformer) and the thermostat lead wire at the
ignition control.
4. Disconnect the sensing probe lead from Terminal 4 on the ignition
5. Disconnect the high voltage cable from the spark transformer.
6. Disconnect the Pilot Valve 1 and Main Valve 3 leads from the
terminal board or end plug-in Heyco terminals (see Figures 2 and 3).

Blower Time Delay Fan Control:
7. Remove Screws A and B holding the ignition control assembly to the
valve and plate assembly (see Figure 1). These two screws are located
on the bottom surface of the ignition control assembly.
8. Remove the ignition control.
9. Disconnect the pilot burner tubing from the pilot tap connection on
the gas valve (see Figure 1).
10. Verify (when looking on the inlet of the valve) that the location of the
grommet and wire leads on the old valve and new replacement valve
are on the same side.
If they are not on the same side, remove the grommet of the new
replacement valve and insert it into the other side of the mounting
plate (see Figure 4). This allows the placement of the ignition control
spark transformer over the outlet of the valve instead of the inlet.

Blower Time Delay Fan Control:

11. Remove the old valve from the manifold and install the new
replacement valve. Ensure the gas flows through the valve body in the
direction indicated by the arrow on the valve body. If the valve is
installed with the gas flow opposite the arrow, leakage can occur.
A thread lubricant has been factory applied to the first two or
three threads of the valve inlet and outlet to avoid galling. Use an
approved pipe-joint sealing compound on male threads before
assembling. Take care that excess compound does not work into the
valve and get onto the valve seats. Threads of pipe and nipples must
be smooth and free of tears and burrs.
12. Reconnect the pilot burner tubing at the pilot tap connection.
13. Fasten the ignition control assembly to the valve and plate assembly
with the screws provided with the replacement valve.
14. Break off the portion of the plate that protrudes if it interferes with
surrounding surfaces (see Figure 4).
15. Reconnect the thermostat leads, the sensing probe lead, and the high
voltage cable according to the labels on the wires. Do not connect
the electrical supply at this time.
a. On grounded versions (part numbers ending with the
letters H, L, G, or J [e.g., G60QBG or G60QBJ]), connect the
black lead wire to one of the ground terminals on the ignition
control. Four ground spade terminals are located just below the
terminal board on terminal board models (see Figure 2) or in a
square arrangement on the end of the plug-in Heyco models
(see Figure 3).
On ungrounded versions (part numbers ending with a K
[e.g., G60QBK]), connect the black lead wire to Terminal 5 on
the ignition control.
On systems using G600 ignition controls, connect the black lead
wire to a ground terminal on the ignition control.
b. Connect the blue lead wire to Terminal 1 on the ignition control.
IMPORTANT: To permit verification of pilot operation, do not connect
the red lead wire to any terminal at this time.
16. Check for leakage.
a. Open the pressure connection between the manual shutoff valve
and the VLV valve.
b. Connect air tubing with a maximum pressure of 1-1/2 times the
valve’s maximum operating pressure (as indicated on the valve)
to the opened pressure connection.
c. Paint all valve body connections with a rich soap and water
If bubbles occur, this is an indication of a leak. To stop a leak,
tighten joints and connections. Replace the part if the leak
cannot be stopped.
If bubbles do not occur, remove the air tubing and close the
pressure connection.
17. After installation of the replacement valve is complete, except for the
attachment of the red lead wire, turn on the gas at the manual
shutoff valve.
a. Reconnect the power supply lead wire to the ignition control and
turn the power On.
b. Set the thermostat to the highest setting. The pilot valve will
open, spark will be energized, and the pilot will light.
c. Test for gas leaks in the pilot line with a soap solution.
d. After the check is complete, turn off the power and connect the
red lead wire to Terminal 3 on the ignition control.
18. Turn on the power and set the thermostat to the desired setting.


IMPORTANT: All adjustments must be made in conjunction with
the gas appliance and in accordance with the
appliance manufacturer’s instruction. Only
authorized personnel should make adjustments.

! WARNING: Explosion Hazard. The minimum flow rate of the
valve must not be adjusted below the minimum safe
working rate of the appliance.

The pressure regulator is adjustable and has been factory set. If a different
setting is desired, follow these instructions.
1. Shut off all gas to the appliance.
2. Turn the thermostat to the lowest setting or Off position.
3. Remove the pressure tap plug at the valve outlet or in the manifold
pipe downstream of the valve.
4. Install a manometer or pressure gauge suitable for measuring the
desired orifice pressure.
5. Remove the seal screw at the end of the regulator stack.
6. Turn the gas on and place the thermostat at the highest setting to
cycle the ignition system.
7. Allow the system to stabilize. Adjust the screw in the regulator stack
to the desired reading on the manometer. (Turn clockwise to increase
the outlet pressure and counterclockwise to reduce the outlet
8. Reinstall the seal screw, which incorporates the proper size hole for
venting to the atmosphere. (It may be necessary to cycle the valve
several times to verify the desired outlet pressure.)
9. Turn off the gas supply and place the thermostat at the lowest setting.
10. Remove the pressure manometer and reinstall the pressure tap plug.
11. Turn the gas on and set the thermostat to the desired setting.
12. Check for leaks at the pressure tap plug with a soap solution before
leaving the site.


! WARNING: Fire or Explosion Hazard. Avoid personal injury
or property damage by making sure the valve
functions properly and there are no gas leaks.
Follow this checkout procedure before leaving the
Make sure all components are functioning properly by performing the
following test:

1. Test for leaks on all pipe joints and connections upstream of the gas
valve with a soap solution.
2. Turn the thermostat to a low setting.
3. Turn on the gas and purge the gas lines of all air.
4. Turn the thermostat to a high setting. The appliance should operate in
accordance with the manufacturer’s specified sequence of operation.
5. Test for leaks on all pipe joints and connections downstream of the
gas valve with a soap solution.
6. Turn the thermostat down for at least 30 seconds and then back up
again. Verify successful ignition at least three times before leaving
the installation.
