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

Maintenance, Factory Technicians, and other Professional Trades that
require ease-of-use features such as a large lighted display with digital
informaon to more quickly pinpoint combusble gas leaks, and at lower
concentraons vs. convenonal 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 & Vibraon), plus 3 Gas
Concentraon 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 Concentraon key
for locang leaks down to 10 PPM. It also features Auto Calibraon, Auto
Zero, Auto O and a rechargeable lithium-ion baery.
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 combusble.
SENSOR FUNCTION
To detect combusble 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 concentraons 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 concentraons.
2. VIBRATION ALARM
The LSCG keypad has a dedicated key for turning the Vibraon alarm
On or OFF. This alarm is parcularly useful in noisy surroundings

8
where the audible alarm might be dicult to hear. Vibraon frequency
increases as gas concentraons increase.
3. “PPM SPEEDOMETER” (ON THE DISPLAY)
At the top of the LCD display, there is an innovave 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 reect the PPM level being detected. This speedometer
scale helps technicians (in their peripheral vision) to monitor the “rate
of gas concentraon 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 combusble gas (having a Methane com-
ponent), it generates numerical “PPM” (“Parts Per Million”) values
of Methane on the LCD display. A key benet of this innovave digital
display is that it gives HVAC/R technicians specic, real me, combus-
ble gas concentraon values. Therefore, technicians don’t need to
remember what mulple LEDS represent as is commonly required
on compeve 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 concentraons of combusble gas(es) can cause explosions,
res and other hazards that could cause serious personal injury or
death.
4. Before entering a jobsite, idenfy/conrm, what gases are known
or likely to be present on or around the jobsite.
5. Advance informaon allows technicians to obtain and use any/all
required safety equipment and beer prepare to inspect for gas
leaks. Know the characteriscs of the gas(es) you will be working
with and use proper precauons to avoid hazardous condions.
6. Due to the nature of conned spaces, it’s imperave that technicians
entering conned spaces exercise a high degree of cauon and take
extra steps to ensure their safety while working with or in the vicinity
of combusble gases or combusble substances. Working safely in a
conned space requires technicians to implement careful preparaon,
as well as an understanding of the potenal hazards within the space
being inspected.
Conned spaces present unique dangers when explosive or ammable
gases may be present. Generally, the oxygen content in these rooms
varies only slightly, whereas a conned space traps combusble gases
and vapors. Therefore, a slow leak can quickly reach an LEL required
for combuson or to start a re.
Gas detecon should begin BEFORE a technician enters a conned
space where explosive or ammable gases may be present.
