INITIAL START-UP
4-1
SECTION 4 - INITIAL START- UP
4.1 INITIAL START- UP REQUIREMENTS
The initial start-up of the KC-1000 Water Heater
is comprised of the following steps:
• Installation 100% completed (Section 2)
• Combustion calibration
• Proper setting of controls and limits
• Temperature calibration
• Safety device testing (Section 5)
Installation procedures must be 100% complete
before performing initial start-up. The initial start-
up must be successfully completed prior to plac-
ing the unit into service. Starting a unit without
the proper piping, venting, or electrical systems
can be dangerous and void the product’s
warranty. These start-up instructions should be
followed precisely in order to safely operate the
unit at a high thermal efficiency, and with low flue
gas emissions.
Initial unit start-up must 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 safety
device testing procedures in Section 5 to
complete the initial unit start-up.
An AERCO Gas Fired Startup Sheet included
with each KC-1000 must be completed for each
unit for warranty validation. 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
paragraphs 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 0.4%, and carbon monoxide in
PPM.
2. *A 16" W.C. manometer and plastic tubing.
3. One 1/4” and two 1/8” NPT-to-barbed fittings
for use with manometers.
4. AERCO differential gas pressure regulator
adjustment tool P/N GM-122643 (one
supplied per installation)
5. Small and large flat blade screwdrivers.
6. 7/16" open end wrench and small adjustable
wrenches.
7. Tube of silicone adhesive
*For propane fired units, an additional 8" W.C.
manometer and 1/2" NPT to barbed fitting is
needed.
4.2.2 INSTALLING THE SUPPLY GAS
MANOMETER
1. Close the main manual gas supply valve up
stream of the unit.
2. Remove the 1/4" NPT pipe plug from the
port on the inlet side of the safety shut off
valve (see Figure 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.
