Shutoff Gas Valve

Applications

The BGA Series shutoff gas valve is an electrically operated gas valve that automatically open and close on a demand signal from a thermostat or other controlling device. Typical applications include heaters, wall furnaces, commercial cooking equipment, roof top makeup units and similar applications. The BGA Series can be used with natural gas and LP gas at pressures up to 0.5 psi. Its compact size permits installation in space restrictive applications.

Installation

IMPORTANT: Only qualified personnel should

install or service BASO® Gas Products. These instructions are a guide for such personnel. Carefully follow all instructions in this document and all

instructions for the appliance.

IMPORTANT: Make all gas installations in

accordance with applicable local, national, and

regional regulations.

CAUTION: Risk of Electric Shock.

Disconnect power supply before making electrical

connections to avoid electric shock.

WARNING: Risk of Explosion or Fire.

Shut off the gas supply at the main manual shutoff valve before installing or servicing the BGA Series. Failure to shut off the gas supply can result in the release of gas during installation or servicing, which can lead to an explosion or fire, and may result in

severe personal injury or death.

WARNING: Risk of Explosion, Fire, or

Electric Shock. Label all wires before they are

disconnected when replacing or servicing the BGA Series. Wiring errors can cause improper or dangerous operation and may result in an explosion, fire, or electric shock leading to severe personal

injury or death.

IMPORTANT: Verify that the valve is installed

only in applications where the specified maximum ambient (surface) temperature and maximum operating pressure does not exceed the limits in the

Technical Specifications section.

To install the BGA Series valve:

1. Shut off power to the appliance.

2. Shut off the gas at the main manual shutoff valve.

3. Label each wire with the correct terminal designation prior to disconnection.

4. Compare the voltage on the valve with the power source voltage to ensure the correct unit is being installed. For valves with 25-volt coils, use a National Electrical Code (NEC), Class 2 transformer.

Note: The transformer must be mounted to a

grounded metal enclosure.

5. Ensure that the gas flows through the valve body in the direction indicated by the “IN” and “OUT” or by the arrow on the valve body. If the valve is installed with the gas flow in the opposite direction, leakage can occur.

IMPORTANT: Do not use a wrench on any

surface other than the casting flats provided at the inlet and outlet ends of the valve body. The BGA Series may be damaged in the mounting process if a wrench is used on any other surface.

Using a wrench incorrectly may void the warranty.

6. The BGA Series valve may be mounted on a horizontal manifold with the solenoid coils pointed up (vertical) or in any position not exceeding 90° from the vertical. The valve may also be mounted on a vertical manifold in any position around its axis (see Figure 1). Do not install the solenoid coil upside down. Install vertically wherever possible.

WARNING: Risk of Explosion or Fire.

Verify that there are no gas leaks by testing with appropriate equipment. Never use a match or lighter to test for the presence of gas. Failure to test properly can lead to an explosion or fire and may

result in severe personal injury or death.

7. Installer must be a trained, experienced, flame

safeguard control technician. Threads of the pipe and nipples must be smooth and free of tears and burrs. Steam clean all piping to remove foreign substances such as cutting oil or thread chips. A sediment trap should also be installed in accordance with the National Fuel Gas Code NFPA 54 (see Figure 4). Mount the valve to the pipework, use a quality rated pipe tape, UL listed seal material rated for gasoline, propane, and other gases. If not available, a quality grade pipe dope, a light amount on the male threads, starting two threads away from the first engaging thread. If pipe dope lodges on the valve seat, it will prevent proper closure. Remove excess compound after mounting the valve to the pipework.

8. Check for leakage:

a. Shut off the gas at the main manual shutoff

valve and open the pressure connection between the manual shutoff valve and the BGA Series 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 solution.

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.

9. Make wiring connections. Refer to the Wiring

section for specific wiring instructions.

10. Perform the Checkout section before leaving the

installation.

Wiring

WARNING: Risk of Shock.

Disconnect the power supply before making electrical connections to avoid electrical shock or equipment damage. Ensure that the operating voltage is identical to the information on the product

identification label.

CAUTION: Equipment Damage Hazard.

For 12 VDC, 25 VDC and 25 VAC applications, the

ground wire must not be connected to prevent

possible grounding of the 12 VDC or 25 VDC power supply or 25 VAC transformer secondary.

The BGA Series valve is supplied with 3-tab and 2-tab electrical connections. The tabs of the solenoid coil are male tag terminals, and electrical connections should be made using 1/4 in. (6.35 x 0.8 mm) female, fully insulated push-on terminals. The earth ground terminal is clearly labeled with the earth ground symbol (see Figure 3).

Note: Electrical connections can also be made using pre-wired electrical plugs (DIN 43650 [ISO 4400]).

Setup and Adjustments

Checkout

IMPORTANT: All adjustments must be made in

conjunction with the gas appliance and in accordance with the appliance manufacturer’s instructions. Only authorized personnel should make

adjustments.

WARNING: Risk of Explosion or Fire.

Follow this or an equivalent checkout procedure after installation. Before leaving the installation, verify that the gas valve functions properly and that the system has no gas leaks. Gas leaks can lead to an explosion or fire, and may result in severe

personal injury or death.

Make sure all components are functioning properly by performing the following test.

1. Test all joints and connections for leaks with a rich soap and water solution. If leaks occur, see Step 8

in the Installation section.

2. Close the main manual shutoff valve and wait at least 5 minutes for unburned gas to escape from the appliance, and then reopen the shutoff valve.

3. Turn on the main electrical power switch and close the thermostat contacts. The appliance should operate in accordance with the manufacturer’s specified sequence of operation.

4. Turn the thermostat to a low dial setting to open the contacts. All burner flames should be extinguished. Repeat Steps 3 and 4 in this section at least three times.

5. Return the thermostat to a normal setting before leaving the installation.
