SECTION 4 - INITIAL START- UP
4.1 INITIAL START- UP REQUIREMENTS
The initial start-up of the KC-1000 Boiler is 
comprised of the following steps: 
• installation completed 100%
• combustion calibration
• proper setting of controls and limits
• mode of operation settings (see Section 5)
• safety device testing (see Section 6)
Installation procedures should be completed 
100% before performing initial start-up and initial 
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 void the product’s warranty. 
These 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 KC-1000 must be completed for each 
unit for warranty validation and a copy must be 
returned promptly to AERCO at: 
AERCO International, Inc.

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 is 
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.
