WARNING
LIMITATIONS OF
PROPANE GAS ALARMS
THIS UNIT will not work without power. Examples
causing no power are: Cut lead wires, faulty circuit
connection, a blown or missing fuse, improper supply
(+) or ground (-) connections.
This alarm will only indicate the presence of propane
gas at the sensor. Explosive gas may be present in
other areas. If you smell unusual odors you may have
a gas leak. Immediately call a local propane gas
supplier or fire department to check for possible
leaks.
This alarm may not be heard. The alarm loudness
meets or exceeds regulatory standards. However, if
this alarm is in remote locations or behind closed
doors the alarm may not be heard. Persons who are
hard of hearing may not hear the alarm.
This alarm is not a smoke/fire alarm. It is also not a
carbon monoxide alarm.
This alarm is not suitable for installation in hazardous
areas as defined in the National Electrical Code.
HOW TO TAKE CARE OF YOUR ALARM
To keep your alarm in good working order, you must;
 Test the alarm weekly. (See “TEST
PROCEDURE”)
 Do not block or cover the alarm with any object that
can prevent a gas leak from reaching the sensor.
 Observe the color of the indicator light on the front
of the unit regularly. (See “Operating Instructions”)
 Vacuum the dust off the alarm cover weekly,
(more frequently in dusty locations), using the soft
brush attachment of your vacuum.
 Clean the alarm cover weekly. Hand wash using a
damp cloth, or paper towel. Dry with a soft cloth.
 DO NOT SPRAY CLEANING AGENTS OR
WAXES directly onto the front panel. This action
may damage the sensor, cause an alarm or cause an
alarm malfunction.
WHERE TO INSTALL GAS ALARMS
This alarm is UL

heater, stove or oven. If potential sources of a gas leak
are in separated areas, MTI recommends installing an
alarm in each area. See Figure 1 and 2.
