THEORY OF

The Fuel System: The air pump forces air through the air line. The air is then

OPERATION

pushed through the burner head nozzle. This air causes fuel to lift from the tank. A

fine mist of fuel is sprayed into the combustion chamber.

 

 

 

The Air System: The motor turns the fan. The fan pushes air into and around

 

the combustion chamber. This air is heated and provides a stream of clean, hot air.

 

The Ignition System: The electronic ignitor sends voltage to the spark plug.

 

The spark plug ignites the fuel and air mixture.

 

 

 

The Flame-Out Control System: This system causes the heater to shut down

 

if the flame goes out.

! WARNING

 

Use only kerosene or No. 1 fuel oil to avoid risk of fi re or explosion. Never use gasoline, naphtha, paint thinners, alcohol or other highly fl ammable fuels.

Do not use heavy fuels such as No. 2 fuel oil or No. 2 Diesel. Using heavy fuels will result in:

clogged fuel filter and nozzle

carbon build up on spark plug

use of non-toxic anti-icer in fuel during very cold weather

IMPORTANT: Use a KEROSENE ONLY container. Be sure storage container is clean. Foreign matter such as rust, dirt, or water will cause the flame-out control to shut down heater. Foreign matter may also require you to clean fuel system often.

Moving on to the PH70EDI, this model provides a higher wattage of 7000 watts, making it suitable for larger rooms or open spaces. The heater incorporates advanced infrared technology, which directly warms people and objects rather than the air, resulting in a quick and consistent temperature increase. The PH70EDI also features adjustable heat settings, giving users the ability to customize their comfort level.

The PH100EDI offers an even greater heating capacity with its 10000 watts output. This model excels in commercial environments, such as warehouses or large workshops, where robust heating is essential. It is designed with a durable, weather-resistant casing that ensures longevity even in harsh conditions. The heater's user-friendly digital controls enhance convenience, enabling precise temperature adjustments and timely scheduling for automated heating.

Finally, the PH150EDI stands as the most powerful in the lineup, with a remarkable output of 15000 watts. Ideal for sizable commercial spaces and industrial applications, this model has advanced safety features, including overheat protection and a tip-over switch, ensuring safe operation under all circumstances. The PH150EDI also benefits from a sophisticated heating element that ensures uniform heat distribution throughout the space.

Each of these models exemplifies Desa's commitment to creating efficient, reliable, and user-friendly heating solutions. Their lightweight, portable designs, combined with advanced infrared technology, make them formidable choices for anyone looking to enhance their heating efficiency while minimizing energy costs. With the Desa PH series, users can expect enhanced comfort and warmth tailored to their specific space requirements.
