Do not cover the oven bottom with foil - it can restrict air circulation.
Never use gas ranges for space heating.
Keep flammable materials away from burner flames.
Keep pot handles turned inward.
Have your unit serviced if the burner flame is not blue. The blue flame indicates complete combustion. A yellow flame means air inlets are clogged or burners need to be adjusted.
Schedule regular preventive maintenance checks for your appliances.
Never allow children to turn the burner control knobs on your propane gas range.
Keep the range surface clean.
Do not leave food simmering unattended.
