Component Parts and 
Delivery Set 

The SGOES parts and delivery set consists of the following: 

 

One SGOES infrared combustible gas detector 

 

One Protective Weather Cover 

 

One SGOES Operating Manual  

 

Accessory Kit (bolts, nuts, washers, etc.).  

 

Calibration Magnet (magnetic wand), P/N 611-0005 

Compare the contents of the set to the packing list to be sure all items were received. If any 
items are missing, contact

Visual Examination 

Before installing the SGOES, examine the unit to ensure that: 

 

The nameplates and warning labels are in place. 

 

The external surfaces and joined surfaces of the SGOES casing are free of dents or 
damage.  

 

Make sure all removable parts are joined to the casing as tightly as possible. 

 

Guidelines for 
locating the SGOES 

 

There are no standard rules for selection and placement of sensors since the optimum 
sensor choice location is unique for each application.  Before installing the SGOES, check 
the conditions at the installation site to make a placement determination.   
 
The following guidelines can assist in determining the best possible placement of the 
SGOES: 

 

Locate the SGOES detectors near potential gas leak sources and away from 
excessive heat, light, wind, dust, water, vibration, shock, and radio frequency 
interference (RFI). 

 

Ensure the installation location has sufficient space to accommodate the 
SGOES housing and all necessary cabling. 

 

Mount the SGOES detector pointing horizontally 
 

 

Preparing For Installation 

 

Before installation, evaluate the gas leak locations and other conditions such as 
wind or air currents at the test site and configure the unit for that particular need. 
Also, be sure to consult local installation codes. 

 

Selection of gas sensor location is critical to the overall performance of the SGOES.  Five 
factors play an important role in the selection of sensor locations: 

 

Density of the gas to be detected 

 

Most probable leak sources within the industrial process 

 

Ventilation and prevailing wind conditions 

 

Personnel exposure 

 

Maintenance access
