ITRON RB4000 Installation And Start-Up Instructions

RB4000 and RB1700 Regulator Installation and
Start Up
Warning Itron does not endorse or warrant the completeness or accuracy of any third party
regulator installation procedures or practices unless otherwise provided in writing by Itron.
This product, as of the date of manufacture, is designed and tested to conform to all
governmental and industry safety standards as they may apply to the manufacturer. The
purchaser/user of this product must comply with all fire control, building codes, and other safety
regulations governing the application, installation, operation, and general use of this regulator to
avoid leaking gas hazards resulting from improper installation, startup or use of this product.
Follow your company's standard operating procedures regarding the use of personal protection
equipment (PPE). Adhere to guidelines issued by your company in addition to those contained
in this document when installing or repairing natural gas regulators.
To ensure safe and efficient operation of this product, Itron strongly recommends installation by
a qualified professional.
Prior to pressure regulator installation in any piping, check to ensure that:
•
The upstream and downstream flanges are parallel and the pressure regulating unit can be fitted
without undue stress.
•
The upstream piping is clean of all impurities (sand, welding, slag, or other foreign materials).
•
The pressure regulator is not visibly damaged.
•
The inlet and outlet regulator chambers are completely clean.
After the preceding installation conditions are met, install the regulator in the piping. Ensure the gas flow
direction corresponds to the arrow on the regulator body.
Itron recommends the following safety considerations for regulator installation:
•
The regulator valve body installation is in horizontal alignment.
•
If the incoming or outgoing piping is constructed from ferrous material, piping contains an
electrically insulating joint upstream and downstream.
•
Free passage for maintenance operations.
•
In systems with an on/off gas load, the downstream volume must be greater than 1 cubic foot per
1000 cubic feet per hour of flow rate.
and regulator piping includes:
•
an on/off valve upstream and downstream of the regulator.
•
a manometer or pressure gauge upstream and downstream for the regulator.
•
an upstream filter.
•
a relief valve for accidental overpressure (for example, downstream piping exposed to direct
sunlight at zero flow).
