Below are some of the most frequently asked questions about preheating.

Q. When do I need to preheat?
Whenever the temps are below freezing.

Q. How long should I preheat?
Depending on the conditions, between 20 and 30 minutes.

Q. How long does a 16oz propane bottle last?
When using a lower heat setting, about 75 minutes. A higher heat setting may use 16oz in about 55 minutes. Figure an average of three to four preheats per bottle.

Q. Is propane better than electric?
Propane and electricity are just the fuels for creating heat. To that extent they are equally good. However, there are some noteable differences in how the two types of heaters are constructed that may provide certain benefits.

• You can take a small propane bottle with you, but will electricity be available where you're going?
• Electricity and water don't mix. Snow and wet winter weather can be dangerous when using electricity.

Q. 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.

Q. Is it legal to carry propane in an airplane?
Yes. Federal restrictions apply when transporting hazardous materials for commercial purposes. There are no restrictions when carring propane for personal use.
