Frequently Asked Questions
How does the dual-fuel system work?
The IDF350 features separate fuel systems optimized for either oil/diesel operation or propane/natural gas. The EZ Ball-Valve allows quick fuel type switching on gas models, while the 3-trial ignition system ensures reliable starts.
Is the Frost Fighter IDF350 safe for indoor use?
Yes, the indirect-fired design produces clean, fume-free heat, safe for occupied spaces. All combustion byproducts are vented externally while only heated air circulates indoors.
How do I control temperature remotely?
Add the Frost Fighter Remote Analog Thermostat with a 25-foot cord for precise temperature control from 30°F to 100°F.
What maintenance is required?
Regular maintenance includes fuel filter changes, burner inspection, and heat exchanger cleaning. The GenySis control system (oil models) provides diagnostic readings to simplify troubleshooting and maintenance scheduling.
Are Frost Fighter IDF350 heaters good for construction sites?
Yes. Frost Fighter heaters for construction are specifically designed to handle tough jobsite conditions, delivering reliable, fume-free heat for workers, curing concrete, and thawing frozen ground. The IDF350 is a portable indirect heater, meaning it can be safely placed outside while ducting clean, dry heat directly into enclosed or occupied spaces.z
