4.2.3 PREPARING THE FLUE VENT
PROBE HOLE
1. If the unit has been installed using the
recommended AL29-4C vent, there will be a
3/8” hole, 18” to 24” above the exhaust
manifold. The outer vent section, that covers
vent connections must be loosened and
moved to uncover the hole (see Figure 4.2).
2. If equipped with one, adjust the stop on the
combustion analyzer probe so that it extends
into the flue gas flow without hitting the
opposite wall of the flue. Do not insert the
probe at this time.

4.2.4 INSTALLING THE DIFFERENTIAL
REGULATOR ADJUSTMENT TOOL
1. First, remove the cap from the differential
pressure regulator (see Figure 4.3).
2. Place the gasket from the regulator cap onto
the regulator adjustment tool.
3. Prior to Installing the tools on the regulator,
pull up the tool's screwdriver blade. Then,
thread the tool into the regulator.
4. Engage the tool’s screwdriver blade into the
regulator’s adjustment screw slot.

IMPORTANT
The unit is shipped from the factory set up for
either natural gas or propane, as specified by the
Style No. on the Sales Order. If desired, the unit
can be easily switched from natural gas to
propane (or vice versa) using the regulator
spring change procedure in Appendix J.
For propane units, disregard paragraph 4.3 and
proceed to paragraph 4.4.
4.3 NATURAL GAS COMBUSTION
CALIBRATION
The KC-1000 is shipped combustion calibrated
from the factory. Recalibration as part of a start-
up is necessary due to differences in altitude,
gas BTU content, gas supply piping and supply
regulators. Factory test data sheets are shipped
with each unit as a reference.
The following combustion calibration procedure
closely follows the factory procedure. By
following this procedure, readjustment of
combustion will be kept to a minimum.
