Mounting the Gas Alarm
NOTICE
After mounting the Gas Alarm, test it following instructions in Troubleshooting Guide.
If possible, mount the Gas Alarm to a pipe meeting the criteria discussed in the "Selecting location for installation" section. To mount to a pipe:
(1) Pass a cable tie through the hole at the top of the Gas Alarm.
(2) Wrap the cable tie around the pipe and tie off.
If mounting to a pipe is not feasible, mount the detector to a wall. (1) Choose a location on the wall
between 4 inches (0.1 meters) to 12 inches (0.3 meters) from the ceiling. Make a mark in the Mounting Tab of the Gas Alarm where you will drill the mounting hole. (2) Use a 3/16" (5 mm) drill bit to drill the mounting hole and insert included anchor. (3) Tighten the screw into the anchor until the screwhead is about 3/16 inch (5 mm) away from the wall, leaving enough space for the Mounting Tab. (4) Hang the Mounting Tab on the screw.
