■ Propane gas has a distinctive odor. Learn to
recognize these odors. (Reference Fuel Gas Odor
and Odor Fading sections above).

and repair of the heater, ALWAYS be consciously
aware of the odors of propane gas and natural gas.

good safety practice under any conditions. If you
smell even a small amount of gas, CONTACT
