G95 Series BASOTROL® Single Operator Valve

Applications

The G95 valves are a combination single operator,
automatic valve with a pressure regulator for use in
applications that do not require solenoid redundancy.

Installation

IMPORTANT: Only qualified personnel should

install or service BASO Gas Products® 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.

!

WARNING: Risk of Explosion, Fire, or

Electric Shock. Label all wires before they are

disconnected when replacing or servicing the G95.
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 pressures do not exceed the limits in the
Technical Specifications section.

To install the G95 valve:

!

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 G95. 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.

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 arrow on the valve
body. If the valve is installed with the gas flow in
the opposite direction of the arrow, 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 G95 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. Mount the G95 on a horizontal manifold with the
magnetic operator pointed up (vertical) or in a
position not exceeding 90º from vertical. The valve
may also be mounted on a vertical manifold in any
position around its axis (see Figure 1).

up or dow n but always in

the direction of the arrow.

7. Mount the valve to the pipework. Use an approved
pipe joint sealing compound on the male threads
before assembly. Remove excess compound after
mounting the valve to the pipework. 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
(ANSI Z223.1). See Figure 2.

8. Attach the pilot gas line to the pilot burner fitting
and to the pilot gas outlet of the valve (if used).

!

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.

9. 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
G96 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 indicates 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.

10. Perform the Checkout section before leaving the
installation.
