SECTION 4 – INITIAL START-UP
SECTION 4: INITIAL START-UP
4.1 INITIAL START-UP REQUIREMENTS
The requirements for the initial start-up of the Benchmark boiler consists of the following:
•
Complete the installation (Section 2: Installation)
•
Set proper controls and limits (Section 2: Operation of the of the Benchmark 750 – 3000
Operation and Maintenance Guide, OMM-0122 (GF-206)
•
Perform combustion calibration (Section 4: Initial Start-Up)
•
Test safety devices (Section 5: Safety Device Testing)
All applicable installation procedures in Section 2: Installation 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 below, it will be necessary to perform the
procedures in Section 5: Safety Device Testing, below, to complete all initial unit start-up
requirements.
An AERCO Gas Fired Startup Sheet, included with each Benchmark unit, 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.
WARNING!
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.
4.2 TOOLS & INSTRUMENTS FOR COMBUSTION CALIBRATION
To properly perform combustion calibration, the proper instruments and tools must be used and
correctly 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:
•
Digital Combustion Analyzer: Oxygen accuracy to ± 0.4%; Carbon Monoxide (CO) and
Nitrogen Oxide (NO
•
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
