Installation Instructions

Note: Prior to using the IWTG-Gas Test Gauge

please read the installation instruction in their

entirety and observe warnings and cautions.

The IWTG-Gas Test Gauge is intended
to accurately measure low pressures and
detect the presence of leaks in natural gas
and liquefied petroleum piping.

The gauge is assembled to a 3⁄4" (8mm)
female NPT manifold. It is supplied with an
air valve and a shutoff valve.

Warning: Do not use pipe dope on the threads of the valve or manifold. Use of
pipe dope will void the warranty.

Installation to piping must be accomplished with Teflon tape only. Do not use pipe
dope. After installation of the IWTG-Gas pressurize the system per the applicable
local requirements.

Warning: Do not exceed the maximum pressure indicated on the gauge dial.
Damage due to over pressurization will void the warranty. The gas/air used to
pressurize the system must be dry and free of contaminants. On completion of
inspection and test, discharge air from the system using the air valve.

Caution: This precision instrument must be handled and stored with care.
