Customer Questions & Answers

Are there a lot of false alarms for the explosive gas component of model KN-COEG-3?

Asked by: SuzyQ
My experience after 2 months of use is NO false alarms....I have located it in a small furnace room that contains both a natural gas furnace and natural gas water heater. As for placing it in the furnace room when the instructions say not to place in furnace rooms--It was my only common sense option in the raised ranch home.-----In any event if i had a gas leak and had placed the detector in an upstairs location or down stairs bedroom far from the furnace and incoming gas lines It may be tooooo late as the gas would never reach the detector in time.... Am I missing something by placing It in the furnace room for earliest possible detection of a gas leak? Agan,I have had NO false alarms and like the units, but you must take time and educate yourself thru the instructions.

I have propane heat in a room in my garage. I never knew that you had to have a combination detector to have it to detect a propane leak. This unit does detect propane leaks? Just want to be sure before in purchase.
