PCA
1.0 INTRODUCTION
Introduction
1.1 The Portable Combustion Analyzer
The Portable Combustion Analyzer (PCA) (Figure 1-1) is a commercial
grade, hand held, combustion efficiency analyzer that is designed for
continuous
(on demand) sampling of light industrial and residential
furnaces, appliances, and boilers. The basic instrument is supplied with a
probe, instruction manual, batteries, and carrying case.
Figure 1-1. PCA
Instruction 0024-9219 1-1

Introduction
1.2 Displayed Data
PCA
The PCA directly measures, displays, and stores the following data:
• Room Temperature in °F or °C (Primary Air/Ambient Temperature)
• Flue Gas Oxygen Content in %
• Flue Gas Temperature in °F or °C
• Flue Gas Carbon Monoxide Content (H
2
Compensated) in ppm
(For analyzers having a Carbon Monoxide sensor)
• Flue Gas Nitric Oxide content in ppm
(For analyzers having a Nitric Oxide sensor)
• Pressure/Draft in Millibars, Pascals, or Inches of Water Column
(For analyzers having a draft sensor)
• Differential Pressure in Millibars, Pascals, or Inches of Water Column
(For analyzers having a draft sensor)
The PCA will compute, display, and store the following data for any of the
seven standard fuels:
• Combustion Efficiency in %
• Excess Air in %
• Flue Gas Carbon Dioxide Content in %
• Flue Gas Carbon Monoxide Content referenced to Oxygen in ppm
(For analyzers having a Carbon Monoxide sensor)
• Flue Gas Nitric Oxide Content referenced to Oxygen in ppm
(For analyzers having a Nitric Oxide sensor)
The seven standard types of fuels that can be selected are:
• Natural Gas
• Oil #2
• Oil #4
• Oil #6
• Kerosene
• Propane
• Coal
The PCA continuously monitors flue gas exhaust conditions and updates
the above displayed values during a combustion test. If the analyzer is
equipped with an optional pressure sensor, then draft measurements can
be made simultaneously with the combustion test, or made separately.
The analyzer has the capability of storing data that was collected during
a combustion test or draft measurement. The stored data can then at a
later date be either viewed on the PCA’s display, printed using an op-
tional printer, or downloaded to a computer.

PCA 10 & 40
These basic instruments have the capability of measuring, displaying,
and storing combustion tests. They will also display flue gas Oxygen
content, flue gas Carbon Dioxide (CO
2 ) content, air temperature, flue gas
temperature, combustion efficiency, excess air , and the current fuel
selected. The ‘standard’ PCA 10 stores up to 10 combustion tests, while
the ‘advanced’ PCA 40 can store up to 100 tests.
PCA 15 & 45 with Draft
In addition to the features of the basic PCAs described above, these instru-
ments have the added capability of measuring, displaying, and saving draft
or differential pressure in either Millibars, Pascals, or Inches-of-Water
Column.
PCA 20 & 50 with Carbon Monoxide Measurement
In addition to the features of the basic PCAs described above, these
instruments have the added capability of measuring, displaying, and
saving Carbon Monoxide (CO) content, as well as calculating a CO level
that is referenced to Oxygen. The ‘standard’ PCA 20 calculates CO refer-
enced to 0% Oxygen, while the ‘advanced’ PCA 50 calculates CO refer-
enced to a user selected Oxygen level of between 0–15%.
PCA 25 & 55 with Draft and CO Measurement
These instruments combine the features of all the PCAs listed above.
Instruction 0024-9219 1-3

Introduction PCA

In addition to the features of the basic PCAs with CO measurement, these
instruments have the added capability of measuring, displaying, and
saving Nitric Oxide (NX) content, as well as calculating a NX level that is
referenced to Oxygen. The ‘standard’ PCA 30 calculates NX referenced to
0% Oxygen, while the ‘advanced’ PCA 60 calculates NX referenced to a
user selected Oxygen level of between 0–15%.
PCA 35 & 65 with Draft, CO & NX
These instruments are capable of measuring, displaying, and saving all
measurements as previously described.
Printout Capability
All PCAs have the ability to print the latest test data, or any of the saved
tests, to an optional printer via an infrared link.
CO Sensor Purge
On all PCAs that measure CO, if the ON/OFF k e y is pressed while the CO
reading is 100 ppm or higher, the analyzer will attempt to purge itself of
CO before turning off.

4.0 OPERATION
4.1 Key Pad Functions
Operation
Descriptions of the key pad functions are given below. Note that most of
the front panel key pad buttons perform multiple functions as determined
by what screen is being displayed at the time.
Turns the analyzer ON and OFF. Note that there is a 5 second
OFF-delay that allows an operator to turn the instrument back
ON by pressing the RUN key. This feature prevents the accidental
loss of test data if the analyzer is turned OFF by mistake.
Moves the cursor [ z ] in front of a menu item up through the
displayed items. This key also increases alphanumeric values in
screens requiring a value change.
Moves the cursor [ z ] in front of a menu item down through the
displayed items. This key also decreases alphanumeric values in
screens requiring a value change.
Chooses the highlighted item (the item with the cursor [ z ] in front
of it) in all menus and screens. This key also causes the cursor to
enter the number field in the Password Screen, and causes the
cursor to advance to the next field position in screens requiring
multiple alphanumeric entries.
Starts and stops a combustion test when the Combustion Test
Screen is displayed. Pressing this key in any other screen almost
always returns the instrument to the Combustion Test Screen.
However, there are four situations where this key behaves as an
enter key: 1)
After entering a correct password in the Password
Screen, press the RUN k e y to display the first calibration screen.
2)
After entering an offset or span value in any of the Calibration
Edit Screens, press the RUN k e y to store the new values. 3) After
entering a time or date value in the Time/Date Setup Screen,
press the RUN k e y to store the new values and return the cursor to
the left side of the display. 4)
After entering text in either the ID
Setup or User Name Screens, press the RUN k e y to store the text.

Turns the screen’s backlight ON and OFF.
Instruction 0024-9219 4-1

Operation
4.2 Sampling Hole Location
PCA
The analyzer requires that a ½" diameter sampling hole be made in the
furnace stack to accommodate the probe stop on the Probe and Hose
Assembly.
Locate the sampling hole downstream from the last heat exchanger,
and upstream from any source of dilution, such as a draft diverter
(Figure 4-1) .
Important! As the distance between the last heat exchanger
and sampling point increases, stack loss will falsely decrease
due to heat loss by convection from the flue or stack.
For residential and light-commercial combustion-equipment applications,
the following recommendations are applicable:
• Oil Gun Burners – Locate sampling hole at least 12 in. (30 cm) down-
stream from the furnace breaching, and at least 6 in. (15 cm) upstream
from the furnace side of the draft regulator.
• Gas Burners – Locate sampling hole
at least 6 in. (15 cm) upstream from
the furnace side of the draft diverter
on gas-converted units. For gas-
designed equipment, the probe may
be inserted down into the flue
through the draft diverter or hood.

4.3 Performing a Combustion Test
Operation
Important! Large rapid changes in the temperature of the
analyzer can affect its accuracy. This is important to know if
the analyzer is stored in a cold place (such as an unheated
vehicle in the winter) and then taken into a warm furnace
area. For the most accurate test results, allow the analyzer to
warm up to room temperature before use (about 10 minutes).
4.3.1 Analyzer Turn On and Warm Up
Important! Be sure the probe is at room temperature before
performing the following steps.
1.
Make sure that the analyzer is properly set up per Section 3.0.
2.
Place probe in an area of fresh, ambient air; then press the analyzer’s
ON/OFF key.
3.
Wait for the analyzer to countdown through its 60 second warm-up
period; then perform one of the following:
• If no errors were detected during warm-up, the Combustion
Test Screen will be displayed. Skip Step 4, and go to Section 4.3.2.
• If an error was detected during warm-up, proceed with Step 4.
4.
If one or more errors were detected by the analyzer’s microprocessor
during warm-up, these errors will be displayed at the bottom of the
Sensor Status Screen (Section 4.6). Address any problems now per
Section 7.2; then repeat this procedure starting with Step 1.
NOTE: If the error detected is not critical to your test, the
instrument can still perform any test not using the function
disabled by the error.
Instruction 0024-9219 4-3

Operation
4.3.2 Installing Probe in the Stack
PCA
1.
After making a sampling hole in the stack (Section 4.2), and turning
on the analyzer (Section 4.3.1), screw the probe stop supplied with the
Probe and Hose Assembly into the sampling hole (Figure
4-2).
2.
Insert the probe through the hole in the probe stop, then position the
probe tip inside the stack, near its center. Tighten the thumbscrew on
the probe stop to secure the probe.
