G292 Series BASO® Dual 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 G292. 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.
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 G292 valve:
1. Shut off the gas at the main manual shutoff valve.
2. When installing the valve on the manifold, 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 G292
may be damaged in the mounting process if a
wrench is used on any other surface. Using a
wrench incorrectly may void the warranty.
3. Mount the valve to the pipework. The G292 valve
may be mounted in any convenient position. 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 must
be installed in accordance with the National Fuel
Gas Code (ANSI Z223.1).
4. Attach a thermocouple securely to each pilot
burner, and screw the terminal end to each
BASO® power unit terminal on the valve. Make
sure these connections are clean. Tighten the
thermocouple lead nut finger tight, plus a
maximum of 1/8 turn. Do not overtighten.
5. Pilot gas connections.
a. Internal Pilot Gas Valve Models receive pilot
gas internally from the valve body.
Note: Pilot gas flow comes out of either gas valve
top housing portx.
On internal pilot gas valve models, plumb the
pilot burner fitting to either of the pilot gas ports
on the valve. Plug the unused pilot gas port on
the gas valve. See Figure 1.
