INITIAL START-UP
4-1
Chapter 4 - INITIAL START- UP
4.1 INITIAL START- UP REQUIREMENTS
The initial start-up of the Benchmark Boiler is
comprised of the following steps:
• installation completed
• combustion calibration
• proper setting of controls and limits
• mode of operation settings (see Section 5)
• safety device testing (see Section 6)
Installation should be completed 100% before
performing initial start-up; and the start-up must
be complete prior to putting the unit into service.
Starting a unit without the proper piping, venting,
or electrical systems can be dangerous and
voids the product warranty. The following start-
up instructions should be precisely followed in
order for the unit to operate safely, at a high
thermal efficiency, and with low flue gas
emissions.
Initial unit start-up is to be performed ONLY by
AERCO factory trained start-up and service
personnel. After following the steps in this
section, it will be necessary to perform the mode
of operation settings in section 5, and the safety
control test procedures in section 6 to complete
the initial unit start-up.
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 at:
AERCO International, Inc.
159 Paris Ave.
Northvale, NJ 07647

IS NOT COVERED BY WARRANTY.
CAUTION!
All installation procedures in Section 2 must
be completed before attempting to start the
unit.
4.2 TOOLS AND INSTRUMENTATION
FOR COMBUSTION CALIBRATION
To properly perform combustion calibration, the
proper instruments and tools must be used and
correctly installed on the unit. The following
sections outline the necessary tools and
instrumentation as well as their installation.
4.2.1 REQUIRED TOOLS AND
INSTRUMENTATION
The following tools and instrumentation are
necessary to perform combustion calibration of
the unit:
1. A digital combustion analyzer with oxygen
accuracy to +/- 0.2%, and carbon monoxide
in PPM.
2. A 16" W.C. manometer and plastic tubing.
3. Three, 1/8" NPT to barbed fittings for use
with the gas supply and differential
manometers (two fitting will be used if
differential pressures are taken).
4. AERCO differential gas pressure regulator
adjustment tool P/N 123643 (one supplied
per installation)
5. Small and large flat blade screwdrivers.
6. Tube of silicone adhesive
7. * Digital multimeter with 10 amp and AC/DC
volt capability.
*Although not necessary for actual start-up
procedures, recommended for troubleshooting.
4.2.2 INSTALLING THE SUPPLY GAS
MANOMETER
1. Close the manual gas supply valve up
stream of the unit.
2. Remove the 1/8" NPT pipe plug from the
port on the inlet side of the safety shut off
valve (see Fig. 4.1).
3. Install a barbed fitting into the pipe plug
tapping.
4. Attach one end of a length of plastic tubing
to the barbed fitting and one end to the 16"
W.C. manometer.
