Heiman ZigBee Gas Sensor

I am new to smartthings and need some help adding a Heiman Zigbee Combustible Gas sensor to my hub. I recently bumped the nob on my gas stove before leaving and left with the gas running for over 8 hours. somehow my house managed not to blow up. But I need to get this sensor working so I can prevent this in the future.

Any help would be greatly appreciated. below is the information on the device.
