■ Even if you are not properly trained in the service and
repair of radiant heaters, ALWAYS be consciously aware
of the odors of propane gas and natural gas.
■ A periodic “snif f test” around the heater or at the
heater’s joints; i.e. hose, connections, etc., is a good
safety practice under any conditions. If you smell even
a small amou nt of gas, CONTACT YOUR FUEL G AS
