INSTALLATION INSTRUCTIONS

APPLICATION

These valve operators provide automatic main valve operation in the VB00, VRB00, and VR8440 families of combination gas controls. The operators are interchangeable and can be used either for replacement or to add automatic operation to a C580/CS580 series manual valve. They cannot be used on VR850 series two-stage valves.
The V404, V804, and VSB24 are magnetic operators. They contain an electromagnet that is energized to open the main valve when the thermostat contacts close on a call for heat. The V404/V804/VS824 replacement operator package includes:

• Operator
• Operator Gasket
• Two Round Regulator Gaskets
• 388589BA Mounting Screws for Standard Capacity Valves

The V504 and V524 are mechanical operators. They use a bulb ·and bellows assembly filled with a temperature-sensitive liquid to open and close the main valve. The liquid expands and contracts with temperature changes, expanding and contracting the bellows and operating the valve. V504 provides modulating control; V524 provides on-off control. The V504/V524 replacement operator package includes:

• Operator
• Operator Gasket
• 394018 Red Knob and Setscrew
• 394138 Red Knob and Setscrew
• 394075 Black Knob and Setscrew
• 388589BF Mounting Screws for Standard Capacity Valves

The bulb and bellows assembly must be ordered separately; see Table 2.
Longer screws are required to mount the operators on nigh capacity valves.

Obtain four screws locally as follows:
V404, V804, VS824-No. 8-32 UNG, 1-13/16 in. V504, V524-No. 8-32 UNG, 2-3/8 in.

Ambient temperature ratings are as follows:
V404A, V804A, VSB24A-plus 32 F to 175 F [0 C to 80 C] V404B, V804B, VS824B- minus 40 F to plus 175 F [minus 40 C to plus 80 C].
V504, V524-plus 32 F to 125 F [0 C to 52 C].
The V504 and V524 operators include a pressure regulator; see Table 1 for settings. A separate pres-sure regulator is used with the V404, V804, VS824 operators.

GENERAL INSTALLATION CONSIDERATIONS

When Installing This Product…

1. Read these instructions carefully. Failure to follow them could damage the product or cause a hazard-ous condition.
2.  Check the ratings given in the instructions and on the product to make sure the product is suitable for your application.
3. Installer must be a trained, experienced service technician.
4. After installation is complete, check out product operation as provided in these instructions.

WARNING

Remember that liquefied petroleum (LP) gas is heavier than air and will not vent upward naturally. Do not light pilot or operate electric switches, lights, or appliances until you are sure work area is free of gas. Failure to follow these instructions may result in an explosion.

CAUTION

1. Disconnect power supply before beginning wiring to prevent electrical shock or equipment damage.
2. Turn gas cock to OFF position.
3. On systems with a 24 V valve operator, NEVER apply a jumper across (or short) the valve coil terminals, even temporarily. This may burn out the heat anticipator in the thermostat.
4. NEVER connect a millivoltage operator to voltage age greater than the operator’s rating, as this may destroy the control.

IMPORTANT

In a millivoltage system, the entire system is powered by the millivoltage generated by the Powerpile generator. It is important to clean and scrape all wires before connecting. Solder and tape all necessary splices using rosin flux to· prevent corrosion.Tighten terminal screws firmly. Total control circuit wiring must not exceed 30 ft [9 m] of 2-wire, 18 gauge cable or 50 ft [15 m] of 2-wire, 16 gauge cable.

STARTUP AND CHECKOUT

GAS COCK SETTINGS
The Lite-Rite gas cock knob has three settings:
OFF, which prevents any gas from passing through valve to e.ither main or pilot burner.
PILOT, which permits gas to flow to pilot burner only ON, which permits gas to flow to both main and pilot burners when the thermostat calls for heat.

PILOT LIGHTING PROCEDURE

1. Slightly depress Lite-Rite gas cock knob and turn clockwise to OFF.Wait 5 minutes for all unburned gas to vent.
   WARNING: Remember that liquefied petroleum (LP) gas is heavier than air and will not vent upward naturally. Do not light pilot or operate electric switches, lights, or appliances until you are sure work area is free of gas. Failure to follow these instructions may result in an explosion.

2. Turn the Lite-Rite knob to PILOT, depress it completely, and light the pilot burner while holding it down. Hold the knob down about one minute. If the pilot goes out when the.knob is.released, repeat steps 1 and 2.

3. Turn the knob to ON, and set the thermostat or the dial on the V504/V524. operator above room tem-perature to turn on main burner.

GAS LEAK TEST

WARNING

DO NOT OMIT THIS TEST
With main burner in operation, paint gasket lines between operator, pressure regulator or cover plate, and main valve with rich soap and water solution. Bubbles indicate gas leakage. To stop leak, tighten assembly screws or, if necessary, replace gasket.

CHECKOUT
Place the system into operation, and observe through one complete cycle to be sure all controls function properly. With V504/V524 operator, make sure the burner comes on when room temperature drops below the dial setting, and the system maintains the desired temperature.
