OPERATION WITH PORTABLE GENERATOR

WARNING: Before operating heater or any appliance from a portable generator, verify that generatorhasbeenproperlycon- nectedtoearthground.Improper grounding or failure to ground generator can result in electro- cution if a ground fault occurs. Refertoowner’smanualsupplied by generator manufacturer for proper grounding procedures.

The operating voltage range of the heater is 108 to 132 Volts (120 Volts +/- 10%). Prior to plugging heater into generator the output voltage should be verified (if generator is equipped with the au- tomatic idle feature, the output voltage should be measured with the generator running at full speed).

If the voltage does not measure in this range the

heater should not be plugged into the generator.

Refer to Operation, page 4, for starting, stopping

and resetting heater procedures.

These heaters utilize high-quality kerosene fuel, which offers a robust heating output while maintaining a clean burn. Kerosene is widely available and often more cost-effective than other heating fuels. The heaters are designed to efficiently burn kerosene, ensuring minimal emissions and environmental impact. This makes them suitable for both indoor and outdoor use when proper ventilation is provided.

Safety is a primary focus in the design of Desa high-pressure heaters. They are equipped with multiple safety features, including automatic shut-off mechanisms, which activate in the event of overheating or abnormal operation conditions. Additionally, robust construction ensures durability, allowing these heaters to withstand tough working conditions while providing reliable performance over time.

Ease of operation is another key characteristic of Desa heaters. Many models come with user-friendly controls that allow for straightforward adjustments of temperature settings and fan speeds. Portability is enhanced through built-in handles and lightweight designs, allowing users to transport the heaters with ease.

In conclusion, Desa Kerosene High Pressure Portable Forced Air Heaters offer effective heating solutions that combine high performance, safety, and convenience. With their advanced features, durability, and efficiency, they stand as a reliable choice for anyone needing substantial heat output in challenging environments. Whether for commercial, industrial, or agricultural use, these heaters provide an essential service by delivering warmth whenever and wherever it is most required.
