Force-Air Propane Construction Heater Operating Instructions and Owner’s Manual

FUEL GAS ODOR

LP gas and natural gas have man-made odorants added

specifically for detection of fuel gas leaks.

If a gas leak occurs you should be able to smell the fuel

gas. Since Propane (LP) is heavier than air you should

smell for the gas odor low to the floor. ANY GAS ODOR

IS YOUR SIGNAL TO GO INTO IMMEDIATE ACTION!
