G92 Series BASOTROL® Automatic Pilot Gas Valve

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.

WARNING: Risk of Explosion or Fire.

Shut off the gas supply at the main manual shutoff

valve before installing or servicing the G92. 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.

CAUTION: Risk of Electrical Shock.

Disconnect power supply before making electrical

connections to avoid electrical shock.

IMPORTANT: Verify that the valve is installed

only in applications where the specified maximum

ambient (surface) temperature and maximum

operating pressures will not exceed the limits in the

Technical Specifications section.

To install the G92 valve:

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

2. 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.

3. Ensure that the gas flows through the valve body

in the direction indicated by the arrow on the valve

body when installing the valve on the manifold. 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 G92 may

be damaged in the mounting process if a wrench is

used on any other surface. Using a wrench

incorrectly may void the warranty.

4. Mount the G92 valve on a horizontal manifold with

the magnetic operator point up (vertical) or in a

position not exceeding 90° from vertical. The valve

may also be mounted on a vertical manifold in any

position around its axis (see Figure 1).

Vertical mounting may be 360º

around its axis with the gas flow

either up or down, but always in

the direction of the arrow.

Horizontal mounting limited

to 90º from upright.

5. 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). 6.

Setup and Adjustments Checkout ! 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.

Pilot Servicing If pilot flame problems occur, check the following: • If the pilot flame burns yellow, it may be due to dirt or lint covering the lower portion of the pilot burner. Remove this using a soft brush or a vacuum. • A flame approximately 1/2 in. (12.7 mm) high must surround the thermocouple tip (see Figure 5). • Because this is an electrical connection, the thermocouple lead connection to the BASO power unit must be clean and free of grease.
