INSTALLATION & OPERATING MANUAL
NATURAL GAS STOVE GUARD 2010
Revised June 15, 2011
Warning: This Gas Stove Guard is to be used with Natural Gas Cooking Stoves. It is not designated for use
with Propane cooking Stoves or Space Heaters!
STOVE GUARD is an electronic safety device for use with Natural Gas Stoves. It turns the gas stove OFF when you
forget by using the advanced technology found in security monitoring devices and a specially programmed micro-
controller.
STOVE GUARD controls the stove’s gas supply system to help prevent food and pots from burning, as well as
reducing the risk of fire caused by unattended cooking.
STOVE GUARD is preset at the factory at the highest fire safety setting of one minute.
This is the recommended setting for use by anyone with Alzheimer’s or similar medical conditions.
 When properly installed, adjusted, and set in AUTO mode, STOVE GUARD will automatically shut the gas
stove off if no one is present in the monitored cooking area (about 10 ft.) for a preset period of time.
 STOVE GUARD can also be used in a TIMER mode to set a maximum cooking time, after which the stove
will be automatically be turned OFF.
IMPORTANT TECHNICAL SAFEGUARDS
 DO NOT INSTALL the EMU (Electronic Monitoring Unit):
oDirectly above a heat source or where hot/cold air or steam will blow onto it.
oOn or above a microwave or toaster oven.
oDirectly on or above the gas stove.
 Do not allow grease to build up on the motion sensor window. This will reduce STOVE GUARD’s sensing
range and possibly turn the stove off even when someone is in front of the gas stove.
 Clean the outer surface of the EMU with a clean, damp cloth only. Do not use soaps or cleaning liquids.
IMPORTANT PERSONAL SAFEGUARDS
STOVE GUARD must be tested with the Individual who requires this device and adjusted to their personal needs, as
well as adjusted to the home environment of use to ensure proper functioning. Additional fire safety devices; such as
smoke detectors & fire extinguishers must also be used to ensure complete cooking fire safety.

INSTALLING the EMU (Electronic Monitoring Unit)
The best location for mounting the EMU is under an upper kitchen cabinet approximately 12” (30cm) from the right or
left side of the gas stove, or on the wallapproximately 18” (45cm) from the right or left side of the stove.
Remember: DO NOT place it directly on or above the stove.
MOUNTING TO THE BOTTOM OF A KITCHEN CABINET
 Remove the plastic covers from the 2 holes on the top and bottom of the EMU.
 Feed the two long screws from the bottom to the top of the EMU and screw directly into the
bottom of the cabinet.
 Ensure that the cable is properly routed back to the Power Box.
MOUNTING TO THE WALL
 Mark 2 points on the wall exactly 7 1/16 “ (18cm) apart.
 Drill 2 holes and install two short screws, leaving the screw threads exposed approx. 1/4” (6mm).
 Line up & Place the EMU on the screw heads and slide it down.
 Ensure that the cable is properly routed back to the Power Box.
USING GAS STOVE GUARD
After a power failure or after first use only the red Off LED (number 12 on the first picture) will blink and display (13)
will show "--". For the safety reason the valve is closed and the stove remain turned off until user press the ON button
(1). Preset time is restored. The Stove Guard keeps this user setting even if there is a loss of power.
The Stove Guard has 3 operating modes to control the stove: AUTO, TIMER and OFF.
AUTO mode
Green ON (7) and AUTO indicators (10) light. The AUTO mode allows the passive infrared detector to automatically
shut down the stove (close the valve) if user is out of the sensing area for longer than the preset time (factory default
is 1 minute). Green movement indicator (8) lights every time when movement is detected and resets clock to the
preset time. When the user enters the sensing area, the Stove Guard will turn the Stove Guards timer back onto the
preset time. Display (13) shows number of minutes left before Stove Guard turns off the stove if no movement is
detected. If no movement is detected (user lights stove and left the kitchen) for the preset time Stove Guard will turn
off the stove, display will show "00", red Off LED (12) will blink and the buzzer in the electronic monitor unit will make
two short beeps every minute. If user presses the OFF button (2) the buzzer stops beeping, but the Stove Guard
keeps the valve closed and the stove remains turned off. If ON button is pressed, the stove has gas supply again. To
prevent fire/explosion, turn stove burner knob to OFF position before turning Stove Guard ON. This will prevent gas
from permeating the room. The user must restart the ignition of the stove’s burner manually; Stove Guard will not
restart the stove burners.
DANGER:
ENSURE THAT ALL TOP BURNERS ARE SHUT OFF
BEFORE PRESSING THE ON BUTTON.
TIMER mode
Green ON (7) and TIMER indicators (9) light. In the TIMER mode stove will operate for the preset time (default is 1
minute), which can be adjusted to the cooking time of specific dish. Display shows number of minutes left before
Stove Guard turns off the stove. Once the preset time is over, the Stove Guard will turn the stove off. The movement
detection does not work in the TIMER mode. When display does not show decimal point, time is displayed in minutes.
When decimal point lights between digits on display, remaining time is displayed in hours and tenth of hours.
From 1.7 hours, display goes back to 99 minutes. When countdown timer reach 00 Stove Guard will turn off the stove,
red Off LED will blink and the buzzer beeps every minute until OFF button is pressed.

OFF mode
Red OFF indicator (12) blinks. When the Stove Guard is in OFF mode, the valve is closed, gas is disconnected and
the stove remains turned off.
HOW TO ADJUST THE STOVE GUARD
ON button (1)
Turns ON Stove Guard from OFF mode and resets preset time in AUTO mode. Also connects gas supply. To prevent
fire/explosion, turn stove burner knob to OFF position before turning Stove Guard ON. This will prevent gas from the
stove entering the room.
OFF button (2)
Turns OFF the Stove - disconnects gas supply. When stove is restarted, the timer will be reset to the last setting.
AUTO button (3)
Turns Stove Guard in AUTO mode and resets preset time. Factory preset time is 01 min., max. Time setting is 15
min.
TIMER button (4)
Turns Stove Guard in TIMER mode and resets time to 01 minute. User has to hold the TIMER button for more than 3
seconds. This delay is a safety feature – avoids accidental activation of timer mode.
TIME adjust buttons (5 and 6)
TIME buttons are used for adjusting the preset time for AUTO and TIMER mode. User can choose between 01 and
15 minutes in AUTO and 01 minutes and 7.0 hours in TIMER mode. Left button adds 10 minutes and the right
button adds 1 minute to the preset time. After reaching the maximum, the preset time go to 01 minute. After reaching
99 minutes in TIMER mode display shows time in hours and tenth of hours. Left button adds 1 hour and the right
button adds 0.1 hour (6 minutes) to the preset time.
GAS SENSOR
An additional safety device is a gas sensor. If the gas sensor detects presence of gas in the kitchen, it will shut off the
gas supply to the stove. Buzzer will be continuously buzzing as long as the sensor detects gas.
Display will show "A2" for higher or "A1" for lower gas concentration. When no presence of gas is detected, display
will show "A0", the buzzer will beep every minute and the stove remains disconnected from gas supply. User has to
manually turn off the stove to prevent gas leaking. After that user can press the ON button, Stove Guard will open the
Gas Valve, which will supply gas to the stove. Now the stove can be restarted. For the safety reason, pressing the ON
button will not open the valve as long as gas is detected ("A2" or "A1" shown on the display).
The Gas sensor needs to reach the working temperature in order to detect gas properly. In the first 4 minutes (time
for gas sensor heating) after a loss of power or after first use of Gas Stove Guard, gas sensing is disabled.
SENSING LEVEL ADJUSTMENT (Height Adjustment)
The sensing range of the EMU (Electronic Monitoring Unit) is over 4 meters (around 12 feet) at a radius of 110
degrees. Each time the motion sensor is activated and the STOVE GUARD is in AUTO mode, the green indicator
LED flashes.
 STOVE GUARD features an adjustable sensing height level to prevent the activation of the stove by
small children or pets that might be detected by the passive infrared detector.
 There is a screw located underneath the EMU, which allows you to adjust the viewing height range of the
detector. Normally this does not need to be adjusted.
Note: This adjustment should only be done in the following situations:

Page 6of 6
1. It is determined that the passive infrared detector is detecting movements other than those of the intended
STOVE GUARD user (such as small children, pets, etc.) which will pass within the lower portion of it’s
detection field.
 To RAISE the detection field when the EMU cannot be located higher, slowly turn the screw to the
LEFT.
2. STOVE GUARD is not detecting the movements of the user because its location is set very high up; the user
is very short, or seated in a wheelchair.
 To LOWER the detection field for these situations, slowly turn the screw to the RIGHT.
TROUBLESHOOTING
You cannot light the gas stove:
 The Stove Guard has been shut off the gas supply. Do not forget to press the ON button before
lighting the stove.
 Check connections between the Gas Valve and EMU.
False gas detection alarm:
 The gas sensor did not reach the working temperature. If the Gas Stove Guard was stored in a cold
place, the gas sensor needs more than default 4 minutes to reach the working temperature. Ignore the
false gas detection and keep the Stove Guard powered for a couple of hours.
The EMU’s LEDs do not light up:
 Check that all the connections to the STOVE GUARD Power Box and EMU (Power box has to be
plugged to the wall outlet and EMU has to be connected to the Power Box) and press the ON button.
The green INDICATOR LED flashes without any reason:
 Avoid placing the EMU within the proximity of the following sources of interference that might accidentally
trigger the passive infrared detector:
 Reflective Surfaces: direct airflow from vents, fans and windows.
 Sources of steam or cooking oil vapor.
 Infrared light sources: TV or other infrared Remote Controls.
 Objects causing temperature changes: such as heaters, refrigerators, toasters and ovens.
 Do not place objects that a pet can climb onto (e.g. a cat on furniture) within 10 feet (3m) of the EMU,
or furniture higher than 3 feet (1m).
 In addition, do not aim the EMU at a stairway a pet may have access to.
There was a loss of power (Electrical Outage):
 STOVE GUARD automatically closes the valve and the stove remains turned off until user press the ON
button. Gas sensor is disabled in the first 4 minutes after power is on.
