5. OVERVIEW
This Leak-Seeker brand Combusble Gas Leak Detector (Model LSCG) is
designed for use by HVAC/R, Plumbing, Mechanical Contractors, Facility
WARNING
WARNING

7
Maintenance, Factory Technicians, and other Professional Trades that
require ease-of-use features such as a large lighted display with digital
informaon to more quickly pinpoint combusble gas leaks, and at lower
concentraons vs. convenonal analog (“Lighted LED”) leak detectors.
The LSCG is for use in residential, commercial, and light industrial
environments to quickly identify the presence of and isolate the
location of at least 30 different combustible gases (see list on page
8-9) that have methane as a component.
The LSCG features 2 Sensory Alarms (Audible & Vibraon), plus 3 Gas
Concentraon Alarms (a “Speedometer” PPM scale, a Digital PPM and
Digital LEL% value) to alert and guide operators in virtually any environment.
It also features the largest backlit LCD display in its class, and a 20” (51cm)
exible probe for hard-to-reach areas. It has a High/Low Concentraon key
for locang leaks down to 10 PPM. It also features Auto Calibraon, Auto
Zero, Auto O and a rechargeable lithium-ion baery.
COMBUSTIBLE GASES
Methane typically makes up 80 ~ 90% of Natural Gas, and usually also
contains smaller amounts of Propane (C3H8), Butane (C4H10) and Etha-
ne (C2H6). All four are colorless, odorless, and highly combusble.
SENSOR FUNCTION
To detect combusble gases, the LSCG heats a sensor at the end of the
exible probe. Internal electronics interpret sensor data and communicate
results to the large LCD display.
HIGH/LOW CONCENTRATION SETTING
By pressing the “H/L” Key at any me, technicians can easily toggle between
viewing PPM concentraons within either a LOW Range (10 to 1,000 PPM)
or a HIGH Range (100 to 10,000 PPM).
FIVE TYPES OF ALARMS FOR PINPOINTING LEAKS
1. AUDIBLE ALARM
The LSCG keypad has a dedicated key for turning the Audible
(beep) On or OFF. The audible alarm beeps faster as a technician
encounters higher gas concentraons.
2. VIBRATION ALARM
The LSCG keypad has a dedicated key for turning the Vibraon alarm
On or OFF. This alarm is parcularly useful in noisy surroundings

8
where the audible alarm might be dicult to hear. Vibraon frequency
increases as gas concentraons increase.
3. “PPM SPEEDOMETER” (ON THE DISPLAY)
At the top of the LCD display, there is an innovave analog “speedometer”
display. If no gas is detected, only a “0” will appear at the top LEFT of the
speedometer. But, if gas is detected, the speedometer will “sweep” to
the right to reect the PPM level being detected. This speedometer
scale helps technicians (in their peripheral vision) to monitor the “rate
of gas concentraon change” as they move closer to, or further away
from the source of a leak.
4. “PPM” NUMERICAL DATA ON THE DISPLAY
When the LSCG detects a combusble gas (having a Methane com-
ponent), it generates numerical “PPM” (“Parts Per Million”) values
of Methane on the LCD display. A key benet of this innovave digital
display is that it gives HVAC/R technicians specic, real me, combus-
ble gas concentraon values. Therefore, technicians don’t need to
remember what mulple LEDS represent as is commonly required
on compeve analog leak detectors.
5. “LEL %” NUMERICAL DATA ON THE DISPLAY
For any gas (with a Methane component) detected, the LSCG
will also show an “LEL” or “Lower Explosion Limit” value as a
percent volume. This reading lets technicians know if the gas
being detected is close to, or well away from the point at which
it might combust. More detailed information on LEL can be
found on pages 13-14.

10. CHARGING THE LITHIUM-ION BATTERY
WARNING
DO NOT CHARGE THE ENCLOSED LITHIUM BATTERY IN THE PRESENCE
OF COMBUSTIBLE GAS. Set up and operate the gas detector according to
these procedures to reduce the risk of re, explosions and serious injury
and incorrect measurements.
1. IF BATTERY IS LOW, CHARGE IT IN AN AREA KNOW TO BE FREE OF
COMBUSTIBLE GAS) by using the original 5V/1A plug and cord supplied.
11. INITIAL PREPARATION
1. Before each use, inspect the LSCG and correct any problems to reduce
the risk of injury or incorrect measurements.
2. Ensure that all equipment has been properly inspected.
3. High concentraons of combusble gas(es) can cause explosions,
res and other hazards that could cause serious personal injury or
death.
4. Before entering a jobsite, idenfy/conrm, what gases are known
or likely to be present on or around the jobsite.
5. Advance informaon allows technicians to obtain and use any/all
required safety equipment and beer prepare to inspect for gas
leaks. Know the characteriscs of the gas(es) you will be working
with and use proper precauons to avoid hazardous condions.
6. Due to the nature of conned spaces, it’s imperave that technicians
entering conned spaces exercise a high degree of cauon and take
extra steps to ensure their safety while working with or in the vicinity
of combusble gases or combusble substances. Working safely in a
conned space requires technicians to implement careful preparaon,
as well as an understanding of the potenal hazards within the space
being inspected.
Conned spaces present unique dangers when explosive or ammable
gases may be present. Generally, the oxygen content in these rooms
varies only slightly, whereas a conned space traps combusble gases
and vapors. Therefore, a slow leak can quickly reach an LEL required
for combuson or to start a re.
Gas detecon should begin BEFORE a technician enters a conned
space where explosive or ammable gases may be present.
WARNING

11
It’s important to understand that jobsite conditions can change
suddenly. The LSCG sensor isn’t able to discern what specic gas
(or combinaon of gases) is being measured. Instead, the LSCG
sensor is designed to detect a range of gases (see pages 8-9) that
have “methane as a component”.
7. Operate this device according to these procedures to reduce the risk
of re, explosions and serious injury and incorrect measurements
1. Ensure there is no dirt, oil, grease, or other petroleum products on
the LSCG housing or covering the sensor area. Such materials could
cause false or distorted readings. Use only a so, damp cloth to clean.
Do not use any detergents.
2. Check the LSCG for any damage, worn parts, loose connecons or any
other problems that might aect safety and normal operaon.
3. If replacing the sensor, ensure the LSCG is turned OFF. This prevenve
safety measure can reduce personal injury and instrument damage
problems.
4. Use only accessories recommended or supplied by CPS Products, Inc.
for this device. Accessories suitable for one brand of equipment may
become hazardous when used with other equipment.
5. Do not use any powered equipment if the power switch does not turn
it ON and OFF. Any powered tool or device that cannot be controlled
with an On/O switch is dangerous and must be repaired or replaced.
6. After inspecting this device, and reviewing the Troubleshooting
Guide, if any doubts, set this device aside and don’t use for the
time being.
12. QUICK START GUIDE

e. If Entire LCD Flashes & Beeps- Sensor has failed and should
be replaced.
4. AFTER INITIAL START UP
a. Speaker & Vibration Alarm Icons Visible On the Display-
Both will be ON (visible in the upper LEFT) by default. These
indicate that the Audible and Vibration alarms will operate if
the LSCG detects a combustible gas. To turn either alarm
OFF, press one or both keys on the keypad.
a. APO (Auto Power OFF) Visible At Top Of Display -APO is the
default setting.
i. If “APO” Visible -The LSCG will turn OFF (to conserve the
battery) if device has NOT been used for 10 minutes. To
enable the LSCG to remain ON constantly, press the APO
key so that “APO” is not visible.
5. SET GAS CONCENTRATION
a. Use the Concentration Setting High/Low Key (H/L)
i. X10” (Low Concentration Scale: 10 To 1,000 PPM)- LOW is
the default sensitivity- “X10” will be visible on the RIGHT
SIDE of the display. “X10” means that any PPM value visible
(to its left) is to be multiplied by 10. 10 PPM is lowest PPM
“resolution”. Example: If “5” is visible, 5x10 PPM = 50 PPM
being detected.

13
ii. “X100” (High Concentration Scale (100 To 10,000 PPM))-To
change to this scale, press the YELLOW “H/L Key”. Any
value shown should be multiplied by 100.
6. TEST THE LSCG
a. In an area known free of combustible gas, test the LSCG to
confirm it is working properly.
i. Use a combustible gas (such as an unlit lighter), to confirm
the LSCG detects gas.
ii. If combustible gas is not detected with this simple test, do
NOT proceed with tesng for combusble gas on the jobsite.
iii. If a defective LSCG is still under warranty, return it to the
place of purchase for replacement or refund.
7. SEARCH FOR GAS LEAK(S) ON THE JOBSITE
a. In a piping system, slowly trace the system with the end of the
LSCG. Stop at pipe joints (where leaks typically occur) to monitor
gas levels.
b. If using the default X10 Concentration setting, the LSCG will
alarm at 10PPM (or 100 PPM if using the X100 setting).
8. CLOSELY MONITOR DISPLAY READINGS OR ALARMS
a. As gas concentration levels change, so will:
i. PPM Display (Always ON)- 1,000 PPM (when using the LOW
Concentraon Seng) Or 10,000 PPM (HIGH concentraon
Seng) is the maximum concentraon that can be displayed for
any gas the LSCG will detect.
ii. LEL Display (Always ON)- 20 % is the maximum concentraon
the LSCG will display.
iii. Audible Alarm Frequency- When ON this alarm increases
in step with gas concentration.
iv. Vibraon Alarm Frequency- When ON this alarm increases
in step with gas concentration.
9. WHEN GAS LEAK DETECTION IS COMPLETE
a. Press the ON/OFF key to turn LSCG OFF and store it in the
protective case provided.
APPENDIX
1. LOWER EXPLOSIVE LIMIT (Defined)
The MINIMUM concentration of a combustible gas needed to support

14
its combustion in air is its LOWER EXPLOSIVE LIMIT (or “LEL”). And,
an LEL varies from gas to gas, but most flammable gases are usually
less than 5% by volume (but nearly never greater than 20%). See the
full LSCG Owner’s Manual at cpsproducts.com for more information.
2 . NON EXPLOSIVE / EXPLOSIVE RANGE DIAGRAM FOR
METHANE
BELOW a specic LEL for a combusble gas, the mixture is too “lean”
(not enough gas is present to burn). See the above visual diagram
that applies to Methane only.

5. UPPER EXPLOSIVE LIMIT (Dened)
The maximum concentration of a gas that will burn in air is the Upper
Explosive Limit (UEL). ABOVE the UEL value for a particular gas, there
is too much gas present and not enough air (oxygen) so, the mixture
is too “rich” to burn.
