Both propane and natural gas are colorless and odorless. For safety rea-
sons, an odorant (Mercaptan) is added so that any leak can be detected
by smell. The common detection threshold for smelling the gases is
around 20% of the lower explosion limit (LEL). This can vary greatly
depending on the individuals’ sense of smell and how long they have
been exposed to either gas. The LEL of each of these gases defines the
bottom range of flammability for the gas. Your CO and Gas alarm is cali-
brated to alarm before 25% of the LEL of either gas detected. Therefore,
it is possible that you may smell gas before the alarm activates.
