CHAPTER 4. INITIAL START-UP
4.1 INITIAL START-UP REQUIREMENTS
The requirements for the initial start-up of the Benchmark 2500 and 3000 MBH boilers consists of the
following:
•
Complete installation (Chapter 2)
•
Set proper controls and limits (Chapter 3)
•
Perform combustion calibration (Chapter 4)
•
Test safety devices (Chapter 6)
All applicable installation procedures in Chapter 2 must be fully completed prior to performing the initial
start-up of the unit. The initial start-up must be successfully completed prior to putting the unit into
service. Starting a unit without the proper piping, venting, or electrical systems can be dangerous and
may void the product warranty. The following start-up instructions should be followed precisely in order to
operate the unit safely and at a high thermal efficiency, with low flue gas emissions.
Initial unit start-up must be performed ONLY by AERCO factory trained start-up and service personnel.
After performing the start-up procedures in this Chapter, it will be necessary to perform the Safety Device
Testing procedures specified in Chapter 6 to complete all initial unit start-up requirements.
An AERCO Gas Fired Startup Sheet, included with each Benchmark, must be completed for each unit for
warranty validation and a copy must be returned promptly to AERCO via e-mail at:
STARTUP@AERCO.COM
Do not attempt to dry fire the unit. Starting the unit without a full
water level can seriously damage the unit and may result in injury
to personnel or property damage. This situation will void any
warranty.
ALL APPLICABLE INSTALLATION PROCEDURES IN CHAPTER 2
MUST BE COMPLETED BEFORE ATTEMPTING TO START THE
UNIT.
4.2 TOOLS AND INSTRUMENTATION FOR COMBUSTION CALIBRATION

attached to the unit. The following sections outline the necessary tools and instrumentation as well as
their installation.
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
•
16 inch W.C. manometer or equivalent gauge and plastic tubing
•
1/4 inch NPT-to-barbed fittings for use with gas supply manometer or gauge
