Is a propane heater dangerous?
Not properly used and supervised. Remember: NEVER LEAVE A PREHEATER UNATTENDED! All of our heaters are intended to be used with either a high temperature hose or duct. This way, open flame is never directed where it could cause damage, such as the paint. • Both the SureFire™ and SureStart Pro™ come with a five foot high-temperature hose. • Our FireFli™ model can be used with either the high-temperature hose or four inch metal duct.
