4.2.1 Required Tools & Instrumentation
The following tools and instrumentation are necessary to perform combustion calibration of the
unit:
•
Digital Combustion Analyzer: Oxygen accuracy to ± 0.4%; Carbon Monoxide (CO) and
Nitrogen Oxide (NOx) resolution to 1PPM.
•
0 to 16 inch W.C. (0 to 4.0 kPa) manometer or equivalent gauge and plastic tubing.
•
1/4 inch NPT-to-barbed fittings for use with gas supply manometer or gauge.
•
Small and large flat blade screwdrivers.
•
Tube of silicone adhesive
4.2.2 Installing Gas Supply Manometer
The gas supply manometer (or gauge) is used to monitor the gas pressure on the downstream
side of the SSOV during the Combustion Calibration procedures described in section 4.3.
The gas supply manometer is installed at the upstream and/or downstream location shown in
Figure 4-1.
